Natural Killer Cells Nourish & Promote the Growth of The Fetus

Posted on December 28, 2017August 31, 2020 by Andrew Orr

A study published in the journal Immunity shows that part of the uterine Natural Killer cell population helps to optimize maternal nourishment of the fetus at early stages of development, not hinder it.

These Natural Killer Cells have actually been shown to secrete growth promoting factors that can also reverse impaired fetal growth and help prevent miscarriage, not cause it.

For many year now I have had people contact me and trying to kill the killer cells, or treat high natural killer cells, or wipe out these cells that they are being told is causing them to miscarry, or not be able to hold an embryo.

For those same amount of years I always said that Natural Killer Cells are meant to be there and the reason they are there is because of inflammation and are doing their job. Now finally, what I have been saying has been proven to be true and now we have an explanation of what these immune cells actually do and the mechanism behind it. They don’t harm the embryo at all. They are there to protect it, nourish it and help it grow.

Natural killer cells are among the most abundant immune cells in the uterus during the first trimester of pregnancy, but their numbers decline substantially after the placenta forms. Up until recently many in the fertility profession have led people to believe that Natural Killer Cells are the cause of all their issues and these new findings may have them eating their words.

Not only have women been offered hormones, steroids and the likes that have never been proven to do they say they do, but they not only have major side effects, but could actually be trying to regulate the very thing that is meant to help a pregnancy.

The results of these new findings not only reveal new properties of natural killer cells during early pregnancy, but also point to approaches for therapeutic administration of natural killer cells in order to reverse restricted nourishment within the uterine environment

Acting as our bodies’ frontline defense system, natural killer cells guard against tumors and launch attacks against infections. This is something that I have been trying to explain for years. If natural killer cells are in high amounts, they are there for a reason and that reason needs to be treated, not the high killer cells.

There has been much research on how Uterine natural killer cells promote immune balance and the growth of blood vessels in the placenta, having a positive impact on birth weight as well as fetal growth. But until now, it was not clear which subset of natural killer cells in the uterus are responsible for promoting fetal growth, or whether these cells help to optimize fetal nourishment at early developmental stages.

In the new study it was discovered that a specific subset of natural killer cells in the human uterine lining secretes growth-promoting factors, which are involved in wide-ranging developmental processes. This subset of cells made up a smaller proportion of natural killer cells in the uterine lining of patients who experienced recurrent spontaneous miscarriage and reduced implantation (42%) compared to healthy females (81%). These findings suggest that insufficient secretion of growth-promoting factors by a specific subset of natural killer cells may be responsible for restricted fetal development in humans.

The studies also showed that a deficiency in this subset of natural killer cells resulted in severe fetal growth restriction and defective development of the fetal skeletal system. The studies also showed that the transfer of uterine natural killer cells reversed fetal growth impairments.

For the purpose of promoting fetal growth in humans, it may be possible to transfer natural killer cells via intravenous infusion or the administration of a vaginal suppository to mothers, avoiding the need for invasive procedures. Moreover, uterus-like natural killer cells are a much safer alternative to many of the methods used in immunotherapy and safer that steroids, or other immunosuppressant’s.

Obviously more study is needed, but these findings are about to turn part of the fertility profession upside down and make it re-evaluate itself.

I’ve always said it isn’t the natural killer cells killing off embryos and always said it was from inflammation and inflammatory gynaecological conditions that weren’t being treated.

We now know that stress uterine cells are also a big part of the issue too. I always say treat the cause to treat the symptoms and now we know that Natural Killer cells aren’t part of the cause, they are actually there to help.

If you are having troubles not conceiving, my fertility program may be able to assist you. If you would like to find out more, please call my friendly staff and they will be able to explain more to you.

Take care

Stressed Uterine Cells & Inflammation Cause Miscarriage, Not Natural Killer Cells

Posted on December 28, 2017August 26, 2019 by Andrew Orr

It is stressed uterine cells and inflammation causing miscarriage and causing the embryo not to implant, not Uterine Natural Killer cells.

For the first time the functions of natural killer cells in the womb have been identified by Researchers at the University of Warwick and University Hospitals Coventry

Although it has long been known that the lining of the womb harbours dynamic uterine natural killer cells, no functions have so far been given to these cells outside of pregnancy.

The researchers have discovered that the uterine natural killer cells remodel and refresh the lining of the womb at the time of embryo implantation. This is the first time a role for uterine natural killer cells in the lining of the womb has been identified outside of pregnancy. The research was published on December 14, 2017.

In addition they discovered that this process isn’t always balanced in each cycle. The natural killer cells perform the role of targeting and clearing inflammatory stressed cells, thereby making space for the implanting embryo. However sometimes not enough of these cells are cleared away and sometimes too many are targeted and removed. Excessive inflammation or insufficient clearance by uterine natural killer cells makes miscarriage more likely.

For many years I have been trying to tell people that they need to stop trying to get rid of the natural killer cells, or reduce their numbers. I have long known that natural killer cells are meant to be in the body and their job is to protect us from infections, bacteria, cancers, tumours and inflammation.

If killer cells are in high numbers, it means that there is something wrong and that is what needs to be treated, not the killer cells. But unfortunately, many clinics play on couples emotions and the use of the word “Killer”. So then we get this war on killer cells and people wanting to kill the killer cells because they think it is killing their babies.

No matter how hard I have tried to explain it, people just don’t listen and now it is finally great to have the research to back up what I knew all along, plus additional knowledge of how Killer cells actually help with implantation and reducing miscarriage.

The researchers have explained what happens if the natural killer cells cannot do their job properly, or there is inflammation that they haven’t been able to target. They said that a good analogy is Swiss cheese: without holes, the embryo has nowhere to go which will cause implantation failure; but if the holes are too large, the tissue will physically collapse and lead to miscarriage.

This imbalance, which may be short-lived or last for multiple cycles, explains the high rate of early pregnancy failure. It really can be a numbers game on how long that cycle could last and why it is important to make sure there are enough natural killer cells there to do their job properly. Without the natural killer cells, there is more chance of inflammation and stressed uterine cells being left behind, which will then lead to higher pregnancy loss and reduced implantation.

The researchers conducted an analysis of 2,111 endometrial biopsies, which is more than had ever been conducted previously. The research team examined the acutely stressed cells in the lining of the womb which generate tissue inflammation. They found that the natural killer cells which are in the womb perform the important function of selectively targeting and eliminating acutely stressed cells.

When there are high acutely stressed cells in the lining of the uterus, the lining of the uterus fails to sense the chemical signals from the fertilised egg and it then silences many of the genes involved in allowing the embryo to implant and embed into the uterus.

One of the chemicals needed for this process to take place is Trysin, which is a common enzyme the embryos gives off. If trysin isn’t detected the embryo is not accepted and left to disintegrate and then the cycle is reset once again. The lack of Trysin signal appears to indicate to the endometrium that the quality of the embryo is not very high and initiates a reduction of receptivity to implantation. These findings could help to improve the success rates of IVF, because one of the biggest problems with IVF is getting the embryo to implant

The research team also found that high numbers of Natural Killer cells in the endometrium are not only a sign of high inflammation and acutely stressed uterine cells, but also indicate a insufficient production of steroids, which in turn leads to reduced formation of fats and vitamins that are essential for pregnancy nutrition.

Again, this is exactly what I have been trying to say for years and why when I treat women who are having implantation issues and recurrent miscarriage I look at treating the cause of the issue, rather than masking it.

To treat miscarriage and help with embryo implantation you need to do the following

Reduce inflammation in the uterine environment and pelvic cavity
Make sure the pelvis, tubes and uterus have been surgically evaluated properly prior to conception, or assisted reproduction (IVF, IUI, ICSI etc)
Increase blood flow and nutrients into the uterine lining
Ensure adequate essential fats and nutrients are given prior to conception
Reduce stress levels
Increase protein and reduce inflammatory refined carbohydrates
Make sure the couple in are optimum health (healthy sperm + healthy eggs=health baby)
Make sure the man is being treated at the same time the woman is (up to 85% of miscarriage issues are related to chromosomal and DNA factors related to poor quality sperm, which cannot be measured by a normal semen analysis)

We need to stop blaming high NK cells as being the cause of miscarriage and embryos not implanting. We need to look at the real cause, which is inflammation, stressed uterine cells ( due to stress in the person), lack of nutrients and blood flow in the uterus and lifestyle factors that is also leading to increase miscarriage rates and reduced embryo implantation.

Let’s not forget that faulty sperm and DNA damage and chromosomal issues with sperm are also a big part of miscarriage too. Miscarriage is not just a woman’s issue. To be honest, statistically it is more likely to be on the male side of the equation and often gets overlooked. But that is a whole other post in itself.

Couples who are part of my fertility program are educated on issues such as this and all the things they need to do to assist them in having a child. The program has assisted over 12,500 babies into the world and my motto is “No Stone Left Unturned.”

Hopefully in the future this new information will be used to screen women at risk of reproductive failure and help with new treatment options for women suffering recurrent miscarriages or recurrent IVF failure.

If you are having trouble conceiving my fertility program may be able to assist you in getting the answers that you need. If you would like to find out more about my fertility program, please call my friendly staff to find out more.

Early Intervention & Early Management Is Vital For Gynaecological Conditions & Menstrual Issues

Posted on December 22, 2017June 19, 2018 by Andrew Orr

By now many of you would know my stance on Period Pain not being normal and that the sooner you get the cause treated and managed the better one is going to be in their day to day life.

Unfortunately not everyone knows that Period Pain is not normal and neither are some of the other symptoms women get each month with the onset of their menstrual cycle. Having heavy bleeding, bleeding in between cycles, menstrual cramps, severe pain, irritable bowel like symptoms, dark clotting, ovulation pain, bowel and bladder pain and urgency etc, are all not normal symptoms that a woman should endure with her cycle. Getting these symptoms at any time of your cycle is not normal either.

Early intervention and early management is the key to any disease state in the body and this definitely applies to menstrual issues and gynaecological disorders. Once a disease is expressed into the body, it can be very hard to treat, especially if it is left a long time and then inflammation spreads to other parts of the body, or in close proximity to where the initial disease was first expressed.

One of the reasons that prompted me to do this post was after a young woman, now in her 30’s, had contacted me and thanked me for helping her back when she was in high school. Since then I have known all of her family well and helped with maintaining their health. At the time she was about 14 years old and showed all the signs and symptoms of endometriosis. She was in so much pain each month, when her cycle came, and she was often curled up on the floor with nausea and vomiting from the pain. Everyone, including GP’s etc, had told her this is normal and that she needed to get used to it. They also told her that she is too young to have endometriosis, or any major gynaecological condition.

That is so bad. Please, please know that period pain IS NOT normal and that teenagers are not too young to have endometriosis. To be honest, they are now finding endometriosis in young girls under 10 years old. Many gynaecological issues can start very early on in a woman’s life, especially if there are hereditary factors involved. Gynaecological and menstrual issues can be passed from generation to generation, so if mum, or your grandmother, or someone in your family tree had menstrual issues, or a gynaecological condition, there is a good chance that you may inherit this as well.

The long and short of it all was that her mother was also getting frustrated at everyone not helping and somehow ended up finding out about me and ended up in my clinic. From there I got her into one of the advanced trained laparoscopic surgeons I work closely with as soon as possible and this is where stage 4 endometriosis was found and excised properly. Without coming to see me, this poor girl would never have found the cause of her menstrual pain and associated symptoms. I then did all her management of her disease moving forward. The main thing that this young girl and her mother were worried about was how this was affecting her education and daily life, but how this could also affect her future fertility.

The one thing I know is that the sooner there is intervention and treatment, the better the prognosis for a woman’s future fertility is. The one thing I do know is that endometriosis doesn’t always cause infertility, but it can make it harder to fall pregnant, if it isn’t managed early enough. The longer you leave a disease in the body untreated, the worse it gets, and then the symptoms get worse and the worse the future outcomes may be.

Lucky for this young lady is that she did have early intervention and management and she has proudly messaged me to tell me that she has had her 3^rd child and that she puts it all down to me helping her when she was younger. I have many women message me and tell me much the same thing. It is so important not to leave these things just because you are being told it is normal. What the hell is normal about being in so much pain that you feel like you could die?

All too often I see women having gynaecological conditions, like endometriosis, missed and dismissed and that the longer that the disease has been dismissed, the harder it is going to be to treat. That is a sad fact for many women and some will have to endure repeated surgeries due to being missed and dismissed and have a life of issues, if their issue isn’t managed properly either. Many have not seen the right healthcare professionals, or the right surgeon either.

I have discussed in many of my previous posts. Please have a read of my previous posts about this subject and the seeing the right team of people. This is why it is so important to have early intervention and also see a proper advanced trained laparoscopic surgeon who specialises in the excision of disease states like endometriosis. Then there needs to be proper management and treatments and lifestyle changes administered to help with suppression of the disease state, helping with inflammation and improving quality of day to day life.

There needs to be a multimodality/team like approach to the management of women with gynaecological issues, as there is no one single fixes all approach, with any medicine. While surgery may be a necessary part of the overall management of disease states such as endometriosis, it isn’t the saviour that many perceive it to be. Surgery does not sure endometriosis and there is no cure for the disease at present time. Once you have it, it is there for good.

Surgery is a necessary but small part of the overall picture that needs to combine many other treatments and modalities to give the best outcome for a woman overall. Once the surgery is done you need to look at managing and suppressing the disease and this is done by lifestyle changes, dietary changes, acupuncture, physio, herbal medicines, hormone therapies, pilates, yoga, pelvic floor and core exercises and many other modalities depending on one’s individual symptoms.

When I treat women with gynaecological conditions, or menstrual issues, I make sure they all get an individualised, person centred, caring approach tailored to how they are presenting rather than a one treatment for all approach that many seem to get. You won’t get the results you need that way because we are all individuals with different needs and different symptoms overall.

Lastly, please remember that period pain and menstrual irregularities are not normal and that the earlier you get onto it and get it treated and managed, the better your future outcomes will be.

No Bad Carbs + Increased Protein = Increased Fertility & Increased Pregnancy rates

Posted on November 23, 2017September 7, 2019 by Andrew Orr

I know I talk about it all the time, but a good diet, and I mean a good diet (not half hearted, I am trying to do it diet), can actually assist with increased fertility and pregnancy rates

Every day I get people ask me “What can I do to increase my fertility and my chances of pregnancy?”

Well, I always say “How long is a piece of string?”

While there are many things that people can do to increase their chances of a pregnancy, one important thing is starting with a good diet. That is one thing “You” are solely responsible for and something can do for yourself. This is for the couple too. Not just the woman.

Healthy couples produce healthy babies. That means health men produce healthy sperm and healthy women produce healthy eggs and the combination creates healthy embryos that go on to become healthy babies. It really is a fact. Even for same sex couples, a partner should be supporting their other half in the journey and at the end of the day a healthy diet is going to help everyone live longer to enjoy their children later on, and hopefully grandchildren too.

Obviously there is a lot more to it, and why in my fertility program I cover “everything” for the couple, but this is one way to ensure your body is ready to have a baby. This is also part of my PACE (Primal, Ancestral, Clean Eating) diet that I have formulated.

Recent studies have shown that when the bad carbohydrates (see below) are removed and the protein increased, that the clinic pregnancy rates shot up by 80%. Yes… a massive 80%

Let me explain what bad carbs are. They are:
Refined grains, refined sugars, refined flour products, breads (gluten free included), pastries, heavily processed foods etc. Anything highly refined and man made and highly processed.

Good carbs are the following:
Fresh fruits, fresh vegetables, fresh salads, sweet potato etc, and basically any carbohydrate that is not highly processed and man made.

Decreasing bad carbs and increasing protein increases embryo quality

The other thing that is important is that eating this way also improved the embryo quality. Blastocyst development was higher in the high-protein group than in the low-protein group (64% vs 33.8%), as were clinical pregnancy rates (66.6% vs 31.9%) and live birth rates (58.3% vs 11.3%). (1)

Reducing carbohydrates and boosting protein intake can significantly improve a woman’s and couples chance of conception and birth according to the research presented at the American Society of Reproductive Medicine (ASRM) several years ago.

The effect is “at the egg level,” said lead investigator. He presented the findings here at American Congress of Obstetricians and Gynecologists 61st Annual Clinical Meeting.

Refined Carbohydrate-loaded diets create a hostile egg and embryo environment even before conception or implantation, he explained.

“Eggs and embryos are not going to do well in a high-glucose environment.” By lowering carbs and increasing protein, “you’re bathing your egg in good, healthy, nutritious supplements,” he said.

These studies demonstrate how little many in the reproductive medicine and fertility profession know about the effect of micronutrients in our diets on various aspects of reproduction.

These studies demonstrate a field wide open for future research and shows how bad carbohydrates (refined grains, refined sugars etc) have an inflammatory effect that affects fertility and pregnancy outcomes and also detrimental to IVF outcomes.

This is why I always promote a grain free, primal based diet (PACE Diet) to all of my patients, especially my fertility and gynaecology patients. It is an essential part of my fertility program. If you do want to find out more about my fertility program, please give my friendly staff a call.

Vitamin D May Increase Fertility & Assisted Reproduction Success Rates.

Posted on November 20, 2017August 25, 2019 by Andrew Orr

Research has shown that there is a relationship between a woman’s vitamin D status and the success rates of assisted reproduction therapy(ART), which includes IUI, IVF and ISCI.

While this is research is nothing new, and something I have been promoting for years, finally it is now official. Women trying to conceive should be taking vitamin D supplements, eating vitamin D rich foods, and getting a healthy dose of the sun daily.

Infertility, or what we call sub-fertility, is becoming an increasing problem and affects millions of people worldwide. More and more people have to turn to assisted reproduction therapy (ART) which now means more and more people are having to use IUI, IVF and ICSI.

The problem is that even with assisted reproduction therapy (ART), at best the success rates are only around 25- 30% on average, and that depends on the clinics individual success rates. Some clinics are also inflating and bodgying success rates to bring in unsuspecting customers.

While there has been much advancements in assisted reproduction (ART) such as IVF and improvements in success rates, the success rates not increased a great deal.

This is why couples need to look at all options and look at preconception care to help increase those success rates. This is why I have set up a fertility program to help educate a couple and assist a couple in everything they need to do in order to increase their chances of a health pregnancy. Couples need to look at a multimodality approach to increasing their chances of conception and this is something is also part of the fertility program.

I often explain to couples that it is like preparing for a marathon; because that is what doing ART can be like. You need to prepare the body (both the man and woman), get the right diet, get the right nutrients, prepare mentally, prepare physically and basically get the bodies into the best shape possible to give the best success. Nobody should ever run a marathon without adequate preparation and the same goes for assisted reproduction.

Vitamin D and reproduction

Researchers across the board know that there is room for improvement in ART success rates. A range of potential factors are being explored, and some scientists have turned their attention to the potential role of vitamin D. While vitamin D is something that needs to be explored, and something that I give to my patients, it needs to be combined with other things mentioned above. It isn’t just as simple as taking Vitamin D and all your fertility problems are gone. But, it is one of the things that can help increase your overall success rates and should be used.

Most of our vitamin D supply is generated in our skin after exposure to sunlight. We do get some from our diets as well. This means that individuals who live in colder or darker environments are more susceptible to lower vitamin D levels, or those who regularly wear clothes covering the majority of their skin, and those who rarely go outside.

The problem these days, many of us have jobs that require us to be inside most of the time and therefore were aren’t getting enough sunlight. The current figures actually show that up to 97% of Australians, and most probably other countries like the US are the same, are actually vitamin D deficient.

The other issue is that even though some of us do get out in the sun, it actually needs to be at a certain time of the day, for optimal absorption. The optimal times are 10am and 2pm in the afternoon. The thing is, most of us aren’t getting out in the sun at these times.

A link between vitamin D and fertility has been theorized for many years and based on a number of observations and studies. This is one of the reasons I have been promoting the use of Vitamin D for more than 20 years now, for those who are on my fertility program. For instance, vitamin D receptors and enzymes have been found in the endometrium.

This is why Vitamin D may be beneficial for women with gynaecological issues such as endometriosis, adenomyosis and other gynaecological conditions.

Vitamin D deficiency has been shown to increase the risk of pre-eclampsia, pregnancy-induced hypertension, gestational diabetes, and lower birth weight. Vitamin D is also essential for a health immune system and reducing inflammation in the body too. It also helps with bone health.

We have also seen that in animal studies, vitamin D deficiency causes poorer fertility and reduced function of the reproductive organs. Many of our breakthroughs in medical science, actually come from animal studies first, especially when it comes to ART and IVF. Many cows and other animals are now impregnated using ART and advancements in this area have helped with human studies.

Vitamin D deficiency and lower success rates

Getting back to the feature studies, Vitamin D was shown to help women undergoing IVF, or intracytoplasmic sperm injection (ICSI), frozen embryo transfer, or both.

All the participants’ vitamin D levels were checked by blood test. What people need to know is that many of the reference ranges still used are actually under review and that if levels of vitamin D in the blood are under 100 Nmols\L, then you need to be supplementing. Anything under 75 Nmols/L is actually deficiency in vitamin D.

This analysis of the current research showed that when women, who underwent ART and had adequate vitamin D levels, were “one third’ more like to have a successful live birth compared to those who were deficient. When compared with women who had insufficient vitamin D concentrations, those with sufficient amounts were “46 percent more likely” to have a clinical pregnancy, and “34 percent more likely” to have a positive pregnancy test result.

Vitamin D is something that I promote and all of my fertility patients are on, as well as other beneficial supplements, diet, emotional support, and medicines etc.

Before you run off trying to buy vitamin D just remember it is just one thing that can help, and it isn’t a miracle cure, but, it may help.

Lastly, before using any supplementations, please consult with a qualified healthcare professional and please don’t self-prescribe, or buy products of the internet. Make sure you buy practitioner dispensed supplements only, which are known to be of the highest quality and not filled with all sorts of things such as heavy metal, low levels of arsenic, toxic fillers etc, which is what some supplements off the internet can have.

The Truth About Natural Killer Cells & Miscarriage

Posted on November 8, 2017August 25, 2019 by Andrew Orr

On a daily basis we get people, who are having failed IVF cycles, calling my clinic looking for some miracle pill, to supposedly eradicate the body of natural killers cell and wipe them off the face of the planet in some war like rage, all because they have been told this will bring an end to their fertility woes.

I wish it was that easy and when my staff go on to explain that treating natural killers cells (uterine killer cells), and especially looking at the cause of natural killer cells (uterine killer cells), is complex, there is no one miracle cure, nor some magic pill, people get annoyed and hang up the phone in a huff ,without listening to the reasons why.

One of the things I always say, when people ask me about regulating natural killer cells for fertility purposes, is “How long is a piece of string?”

This is because this subject is very complex and there are many reasons why natural killer cells may be impacting implantation. So, hence the response is always going to be “How long is a piece of string?”

While Natural killer (NK) cells have an important role in the early responses to viral infections, they have also been linked with failure of pregnancy.

Increasingly, clinics are offering blood tests, at an increased cost to the patient, to measure the number and activity of circulating NK cells. As a result of these investigations, many women are offered treatments such as steroids, intravenous immunoglobulins, and tumour necrosis factor blocking agents. The scientific rationale for these tests and treatments, however, is not always supported by our current knowledge of the function of uterine NK cells.

So, I thought it was about time I set the records straight on the BS information, that seems to being handed around as gospel, by money hungry fertility clinics run by big health conglomerates, and by the rotten Dr Google, about natural killer cells (uterine killer cells) and these supposed miracle pills, that will miraculously fix someone’s fertility issues.

Let’s Look at the Facts about Natural Killer Cells Relating to Miscarriage

There is no miracle pill, or one supposed miracle treatment, or a one pill solution to treat, or get rid of natural killer cells. You do not want to get rid of NK Cells.
Natural Killer Cells are a natural part of the immune system designed to target inflammation, kill of cancer cells, kill off bacteria and protect the body from harmful invasion of foreign organism
There is huge difference between natural killer cells that are circulating in the blood stream, compared to uterine killer cells
Uterine Killer Cells are in large numbers during a pregnancy to protect the embryo
Natural Killer Cells are only in large number and are only being sent out by the immune system because there is some inflammatory process going on in the pelvis, or the rest of the body
You cannot regulate Natural Killer Cells numbers unless you first address the inflammatory process that is causing them to be in high numbers in the first place (Eg- Inflammatory gynaecological conditions such as PID, Endometriosis, PCOS, Adenomyosis, Adhesions, STI’s, CIN, HPV, Herpes etc)
Many people have not had the proper initial fertility investigations and testing needed to actually fall pregnant in the first place and looking at Natural Killer Cells, before all that proper testing etc is done, is actually not assessing the patient properly.
If you do not treat the cause of the Natural Killer Cells being in high numbers, you will not be able to reduce the numbers of Natural Killer Cells that are actually doing the job they are meant to do, which is …. Protect the Body.
Many of the so called treatments for Natural Killer Cells, regarding fertility, have never been approved for such treatment and research on it is still inconclusive.
Some of the treatments being proclaimed as miracle cures (Intralipids etc) are purely money making exercises that are preying on the vulnerability of people who have been told wrong information and have this perception of some killer being inside their body attacking their embryos.
Intralipids have never been proven to treat Natural Killer Cells and are derived from highly inflammatory soy based compounds, which then in turn can cause more inflammation.
The drugs used in the treatment of Natural Killer Cells are steroidal based and carry many side effects and are for more harmful to the body that any natural killer cell will ever be. The steroids are also a category C drug that has been shown to have an effect on the neonate
Steroids, such as Prednisone, do work on regulating NK cells, but they do so by suppressing the immune system, thus compromising a person’s immunity. There are also risk to peoples minerals by using these long term and there are also other side effects to the body.
Natural Killer Cells are there to protect the body, not hurt it.
Natural Killer Cells may only be attacking embryos because they are seen as foreign body as well and when they are there trying to kill of the diseases and issues causing inflammation in the body, they just happen to kill of any other foreign organism and inflammatory processes at the same time
Again, to address natural Killer Cells, you need to address the inflammatory process as to why they are in high numbers in the first place
The perception around Natural Killer Cells being this “thing” killing off embryos in the body is misguided and is actually not a true representation of what Natural Killer Cells actually do. It is purely often used to tug on the heartstrings of unsuspecting patients, who are highly emotive and clinics use these emotions to get them to pay for treatments that have never been fully proven to work.
The name “Killer Cell” is too often exploited in the wrong context by many in the fertility world
Blood tests cannot measure the number of Natural Killer Cells in the Uterus, Only a biopsy can do this.
A Natural Killer Cell (uterine killer cells) Biopsy has to be done between the 24^th and 28^th day of your menstrual cycle to give the best results.
Blood tests can only measure the circulating NK cells in the body and not the uterine killer cell activity, which can be the cause of recurrent miscarriage. So, if you have had a blood test, it is not measuring what is needed. Everyone will have circulating NK cells in their blood stream.
The percentage of CD56+ NK cells in peripheral blood in normal healthy individuals varies from 5% to 29% (2)Despite this, more than 12% NK cells in women with infertility or miscarriage has been arbitrarily defined as abnormally raised and used as an indication for treatment (4)
The percentage of NK cells in blood can be affected by many factors including sex, ethnicity, stress, and age too.
There is now new evidence that shows that natural killer cells help with implantation and a healthy uterine environment, which now supersedes old outdated research.

Natural Killer cells (Uterine killer cells and other NK cells) are the main immune cell-type found in the uterus. Their numbers increase through the menstrual cycle to peak at the time of implantation. If an embryo does implant, NK cell numbers increase further to 70% of all cells.

Uterine NK numbers start to decrease at around the 20 week mark of pregnancy and are all but absent at the end of pregnancy.

Natural killer cells acquired their name as a result of the initial test used to identify them in vitro. Unlike T lymphocytes, NK cells are able to spontaneously kill cells in a non-MHC restricted manner.

Regrettably, this is a misleading name in reproduction, and the powerful image of maternal cells attacking the fetus is emotive and easily exploited. None the less, these NK cells can kill off the embryo at early stages of pregnancy, but there is nearly always a reason why. That reason is inflammation in the pelvic cavity and uterus. This needs to be addressed to regulate the number of NK cells, not some notion of killing off the “Killer Cells”.

Types of Inflammation causing high Natural Killer Cells (Uterine Killer Cells)

Endometriosis & Adenomyosis
PCOS/PCO
Fibroids, Myomas
Vaginal Infections & Bacteria
STI’s
Cancer, Trauma, Localised Lesions & Others
Stress

Yes, stress can lead to a compromised immune system, which then leads to high TNF (Tumor Necrosing Factor) and increase Natural Killer Cells, which then leads to prolonged increase activated T Cells, and this then causes reduced implantation of embryos.

This is also a reason why any inflammation in the uterus or pelvic cavity needs to be addressed to help fix this issue and one of the reasons why any woman having fertility issues needs to be investigated and treated properly.

This needs to involve proper differential diagnosis, proper pathology testing, genetic testing and surgical investigations such as laparoscopy prior to any further fertility treatment. A laparoscopy is the gold standard for addressing and treatment of issues in the uterine and pelvic cavity.

Natural Killer Cells (Uterine Killer Cells) may be a part of recurrent miscarriage, but we need to stop the misinformation and perception of them being some killer organism that isn’t meant to be in the body. They are meant to be in the body and the name is all too often exploited by many to offer unproven treatments and medications by clinics trying to increase profits.

If you want to regulate and treat natural killer cells (relating to recurrent miscarriage) properly, you need to find out what is causing them to be there in the first place. There is no magic pill to get rid of Natural Killer Cells.

You cannot rid the body of Natural Killer Cells anyway. They are meant to be there. You can only regulate the amount of killer cells doing their job and you need to find out why they are in higher numbers in the first place. This is usually because there is some sort of inflammation, infection, bacteria, or malignancy going on in the body that has not been investigated properly in the first place. Let’s not forget that stress, yes stress, increases the amount of Natural Killer Cells in the body too.

As part of my fertility program, I talk to couples about the facts about Natural Killer cells, and makes sure that proper investigations, testing and treatments are administered and managed properly. This can also be done alongside current medical protocols such as the Bondi protocol, or California protocol.

What You “Can” Eat During Pregnancy

Posted on November 2, 2017August 25, 2019 by Andrew Orr

A while back, I put up a post to see what people thought that you (can) and (can’t) eat during… pregnancy, or if you were trying to fall pregnant. It was really interesting to see what foods people thought you could not eat during pregnancy.

It is really interesting that most people want to tell you want you can’t eat, but hardly anyone tells you what you can eat during pregnancy and while trying to fall pregnant.

What prompted this post was that a while back I overheard one of my staff and lovely mother to be, talking to another mother to be about what she has been cutting from her diet while she was pregnant and how her food choices were so limited.

I heard all kind of wonderful things from not eating any seafood; not eating any cold meat, not eating soft cheeses, not eating eggs, not eating nuts and nearly the whole food pyramid was being added.

What many people don’t know is that I actually have a background in food science and that I used to teach about bacteria and food hygiene and the nasty consequences of what bacteria can do to the body.

Most pregnant women have the number one fear of foods containing Listeria. It is a rare form of bacteria but it can be fatal (very rare) to a lady if she is pregnant and cause issues such as miscarriage. So not discounting it at all and some countries around the world do not have the food hygiene standards we have here in Australia.

We only see about 5 cases per million people in Australia. Basically there is about 0.3-0.4% chance of getting it and we all make such a big deal about it. Again, this is not to discount it either. Listeria can be found in unpasteurised products such as diary and cheese and can be found in some forms of deli meats mainly. To be honest, it is usually the home made/backyard deli meats and cheeses you really have to watch, with regards to hygiene and bacteria.

But if a health issues such as Listeria poisoning is so rare, why do we make such a fuss about it and not warn women of other potentially worse factors that cause more cases per year, and can be potentially fatal too. The problem is if women only hear about the foods they can’t eat, many of them are going to be nutrient deficient all for the fear of a tiny chance of listeria causing an issue with a pregnancy.

The truth is, other bacteria such as Salmonella, Shigella and Camphyobacter have a higher rate of infection per year than listeria ever will and nobody ever talks about them. There are over 25,000 cases of these combined and most of the spread is through person to person contact, not just foods themselves.

Basically many food poisoning cases are actually from bacteria being on your own hands, which then at some stage end up in, or near your mouth. This is why smokers are at higher risk of food poisoning. To be honest, shopping trolley handles are probably one of the most unhygienic places you can put your hands on and probably cause more bacterial health issues than anything. Money can be the same.

Then we have a far wider implication of gestational diabetes, which account for about 15,000 plus, pregnant women per year, with an annual increase of 5% per year. When someone eats sugary foods, highly processed foods, grains etc during pregnancy, that are a major cause of diabetes, nobody says a thing. Yet mention the word Brie cheese, cold meats etc and everyone goes nuts. Oh yes, we now mention ‘nuts’ and people go nuts too. Again this is not to discount that some people have true allergies to nuts.

So what do pregnant women really need to know and what can you eat?

Basically the same food hygiene that is needed when you aren’t pregnant is to be observed when you are. There only needs to be a little bit more caution, not an ‘OMG’ stay clear of everything, that unreliable Dr Google, or ‘Someone’, has told you. I would love to know who ‘Someone’ is because he, or she, causes a lot of problems. Remember temperatures between 5 and 60 degrees C are you danger zone area. This is why foods need to be stored below 5 degrees and heated over 60 degrees C.

So what can you eat?

So basically you can eat any deli meats as long as they are cryo-vacced and in date. Cryovacced means the air has been taken out and not even bacteria can live in an non-oxygenated environment.
You can eat all seafoods as long as they are cooked and fresh.
You can eat all cheeses but need to be more careful around the soft cheeses. New research actually shows that small amounts can be beneficial for you. If you cook soft cheeses there is definitely no issue. Just don’t eat cheeses from unpasteurised sources.
You can have any form of pasteurised milk or UHT milk.
You can have soft serve ice-cream as long as the place you are getting it from looks hygienically clean. Maybe not a good idea to get them from the old ice-cream trucks that aren’t checked regularly by food standards.
You can eat nuts and now there is evidence to show that mums not eating nuts during pregnancy may now be the cause of nut allergies.
You can definitely eat eggs and you just have to make sure they aren’t raw. Boiled eggs, poached eggs and fried eggs are all fine. Egg custard is fine because it is cooked
You can eat all meats if they are cooked and you don’t have to char it until it resembles an old leather shoe. Medium is fine. You just need to cook all chicken right through because all chicken contains salmonella and cooking it kills it.
You can have coffee and tea and you just need to limit all caffeine to no more than two cups per day (remember tea has as much caffeine as coffee)

Basically the healthy food pyramid I teach at my clinic needs to be applied.

1. Take a good practitioner only Multivitamin, Omega 3 Oils, prebiotics and probiotics daily

2. Eat 2 handful of nuts daily or two tablespoons of healthy oils

3. Limit you grains to one serve (only) per day or cut them completely (best)

4. Eat 2 pieces of low GI fruits per day

5. Protein with every meal or snack

6. 3-5 serves of veggies or salads per day (just not from a salad bar)

7. 8 glasses of water

8. 2 serves of electrolytes per day when pregnant

9. 30 -45 minutes exercise 2-3 times per week

# No diet drinks or artificial sweeteners, or alcohol at all

Remember food is to be enjoyed and so is pregnancy. Don’t get too caught up in all the worry of what you can’t eat and look more at what you can eat and stick to those foods.

Take care

Alcohol Decreases Fertility & Makes Gynaecological Conditions Worse

Posted on October 31, 2017August 25, 2019 by Andrew Orr

In today’s modern society, alcohol has become the cornerstone for social engagements, business dinners and after work relaxation. It is important to realise however, that alcohol can directly impact the fertility of both males and females.

In males it can decrease sperm quality, reduce testicular size, decrease libido and cause impotence, all of which can impair fertility.

In females it has a more systemic response, affecting the reproductive hormones, leading to abnormalities in the menstrual cycle and an increased risk of miscarriage.

Many men and women these days are actually consuming copious amounts of alcohol and may think that their drinking habits are normal, when compared to others around them.

When people do things on a regular basis, it becomes their normal. But truth be told, many people’s drinking habits, both men and women, are actually in the realms of alcoholism. The impacts of that are far reaching and fertility and gynaecological conditions are definitely impacted by alcohol consumption.

Effect of Alcohol on Conception for Men

Fecundability refers to the probability of conception during a particular menstrual cycle. It is dependent on the reproductive potential of both partners. Alcohol decreases fecundability by its effect on sperm quality and quantity. Men who continue to consume alcohol on a regular basis, can decrease their sperm motility, morphology and their DNA in the sperm. All of which are important factors in achieving fertility.

While outwardly a man’s sperm may look OK, many forget that inwardly, the sperm DNA could be highly fragmented and unless this is tested every ejaculation, you will have no idea how bad the sperm actually is. A one off DNA fragmentation analysis does not mean the sperm each time is OK. It only measures the sperm from the ejaculate that was tested and sperm quality can change by as much as 20% each ejaculation.

Testicular size is also affected by alcohol intake; and can also affect sperm production. Alcohol is a depressant of the central nervous system (CNS), and can disrupt the autonomic system of the CNS. These effects are temporary and short lived. Abnormal sperm production is also temporary and also can resume after abstaining from alcohol.

One study, this one looking at couples going through IVF treatment, found that for every additional drink a man consumed per day, the risk of conception not leading to a live birth increased by 2 to 8 times. This was especially true if the drinking occurred within a month of the IVF treatment.

Effect of Alcohol on Conception for Women

In women, alcohol affects fecundability, by disrupting the delicate balance of the menstrual cycle. Clinical research data published in the “British Medical Journal” suggests that women, who drank socially, 1-5 drinks per week, were at a greater risk of decreased fecundability when compared to women who remained abstinent. These findings underscore the importance of remaining abstinent while attempting to conceive.

Alcohol disrupts the hormonal imbalance of the female reproductive system, leading to menstrual irregularities, and even Anovulatory cycles, (menstrual cycles where ovulation fails to occur). Menstrual pain can directly be linked to the amount of alcohol consumed in the lead up to the menses and consumptions of alcohol, even small amounts, exacerbates most gynaecological conditions. These changes can drastically decrease a woman’s chance of becoming pregnant and thus affect fertility.

Alcohol effects fertility in both partners, and can do so in so many ways. For couples who desire to have a baby, it is best to stay away from drinking completely. Presently there is no safe limit of alcohol intake; even socially acceptable amounts of alcohol can affect fertility potential and outcomes.

Moderate drinking (1-2 drinks in one sitting) is probably okay, especially if you reserve those drinks to a few times a week, instead of daily. However, if you’re going through IVF treatment, or trying to conceive naturally, you might consider cutting out alcohol for the time being.

A woman that is trying to concieve, or trying to improve a gynaecological issues, or menstrual issues, should not be consuming more than 4 standard drinks per week.

A male who is trying to conceive, or have sperm quality issues, should have no more than 2 standard drinks in one sitting and be having at least 2 alcohol free days per week. These are all part of the healthy drinking set out in health department and government safe drinking guidelines.

Trying to conceive is a special time in a couple’s life, it should be filled with love, devotion and safe health practices, which means a healthy diet and lifestyle and having a healthy mind too. It also means having healthy drinking habits as well.

Decreasing alcohol, having bete foods and looking at a healthy detoxification program is also a great idea for those trying to increase their fertility and get their reproductive systems working better. Healthy eggs and health sperm make healthy babies. Healthy reproductive systems also mean better menstrual cycles and better testicular health too.

Safe drinking everyone. This is something I talk about as part of my fertility program and preconception care. If you would like to find out more about my fertility program, please contact my friendly staff to find out more.

Seminal Fluid Improves Fertility in Women and Improves IVF Pregnancy Rates

Posted on October 26, 2017August 25, 2019 by Andrew Orr

Seminal fluid is often viewed as simply a vehicle to carry sperm to fertilize the female egg, but a more complex function in influencing female reproductive physiology is now evident.

Remarkably, seminal fluid contains special signaling agents that interact with the female reproductive tract to prime the immune response, with consequences for fertility and pregnancy outcome. This research isn’t new and we have spoken about this in previous posts.

But we now know a bit more about how sperm may assist in implantation for, especially for IVF.

See my other post https://drandreworr.com.au/sex-around-the-time-of-embryo-transfer-increases-the-likelihood-of-successful-early-embryo-implantation-and-development/

Recent studies demonstrate a key role for seminal fluid in enabling embryo implantation and optimal placental development. In particular, seminal fluid promotes health immune responses which facilitate embryo implantation by suppressing inflammation, assisting uterine circulation and blood supply and also protecting the embryo.

There is emerging evidence where seminal fluid provokes an adaptive immune response in the cervical tissues after contact at intercourse, and spermatozoa accessing the higher tract potentially affect the endometrium directly. Research has now shown that sperm and seminal fluid actually help with endometrial receptivity, which is needed to create the right environment for a healthy embryo to implant.

These biological responses may have clinical significance, explaining why

[1] intercourse in IVF ET cycles improves the likelihood of pregnancy

[2] inflammatory disorders of gestation are more common in women who conceive after limited exposure to seminal fluid of the prospective father

[3] preeclampsia incidence is elevated after use of donor oocytes or donor sperm where prior contact with conceptusalloantigens has not occurred.

Research like this is important to define the mechanisms through which seminal fluid interacts with female reproductive tissues, to provide knowledge that may assist in preconception planning and infertility treatment.

It also bring attention to the fact that couples still need to be engaging in regular intercourse during IVF cycles to help not only with implantation, but to increase pregnancy rates through optimisation on the endometrial lining through contact with seminal fluid.

Regular intercourse also promotes connection and bonding for the couple as well and this is something that is very much overlooked.

My clinic offers a comprehensive Fertility Program where couples are educated on important factors such as this… and more

If you would like to find out how you could improve your chances of having a baby, please give my clinic a call and ask about my fertility program that has assisted over 12,500 babies (and counting) into the world may be able to assist you as well.

Facts About Sperm Health and Their Lifespan

Posted on October 25, 2017August 25, 2019 by Andrew Orr

There is a lot of misinformation with regards to facts about sperm health and their lifespan.

Typically, millions of sperm cells are produced in the testicles every day. During this time, many things can affect their formation and interfere with their quality and maturity.

It takes around 90-120 days for a sperm to become motile

From a tiny sperm cell it can take between 90-120 days before a sperm is fully mature. The sperm eventually develops a head and tail, so that its cells start to resemble the shape of a tadpole.

The head contains all of the DNA, or genetic material, and the sperm uses the tail to help it move. A sperm doesn’t reach full motility until it actually reaches the egg, where when touching the egg it creates a reactions that causes “super motility” to give it the final power to push inside the egg. This is called the acrosome reaction.

There has been lots of debate about the actual time it takes for a sperm to mature and become fully motile, but general consensus is that it will take somewhere between 90-120 days.

This is why it is important that men look after their health long prior to conception, because the sperm they ejaculate today was created around 90-120 days ago and what they did to their bodies at that time, will influence how healthy those sperm are.

A man’s lifestyle affects his sperm quality

So if a man had a poor diet, was drinking, smoking, had heaps of stress and goodness knows what, this can all have an impact of the maturing sperm and this can result in poor sperm quality and damage to the DNA of the sperm, which will then be carried onto his offspring, should the sperm be successful in fertilising an egg. This is why the couple need to be healthy prior to conception, not just the female.

Biology 101 tells us it take a sperm and an egg to make a baby, not just an egg. Sperm quality issues make up a big part of fertility issues and they can also be a big part of miscarriage issues too. I have spoken about this many times in previous posts. Up to 85% of miscarriage issues can be related to chromosomal and DNA factors related to poor quality sperm and this is often very much overlooked.

What factors impact on sperm health?

There are always many factors that can affect the sperm formation process and interfere with sperm quality and the DNA of the sperm.

Health and lifestyle factors

Recreations drugs, medications or alcohol use
job, or occupation
tobacco use, or smoking in general (including recreational drugs)
stress
overheating the testicles (spas, saunas, bike riding)
excess weight gain and excess body fat
Trauma
Bike riding (due to heat and trauma through the seat of the bike)
Poor diet and nutrition
Excess sugars and additives
Preservatives and artificial colours and artificial sweeteners

Environmental causes

exposure to industrial chemicals
heavy metals
radiation or X-rays

Medical reasons

infection of the testicles
cancer of the testicles
swelling of the veins (varicoceles etc) that drain blood from the testicle
hormone imbalances
physical problems in the tubes that carry sperm through the reproductive system
chromosomal or genetic disorders (such as Kleinfelters syndrome)
certain medications
surgery involving the pelvis, abdomen, or reproductive organs

How long do sperm live inside the female body?

There is always a huge misperception about how long sperm can survive outside the man’s body and when they enter into the female reproductive tract. Many women are told all manner of untruths of sperm lasting for weeks at a time. The truth is that sperm cannot survive for long once they are released.

Precisely how long they can survive depends on the environment that they are released into and how quickly the fluid surrounding the sperm cells dries up.

Sperm lifespan inside the female body

After ejaculation, sperm may be able live inside the female body for several days, but that is dependent on many varying factors once they enter a woman’s body. To be honest, most of the 300-500 million sperm are dead with an hour. That is a fact.

The fluid in a woman’s reproductive tract, especially the fallopian tubes, has all of the nutrients that sperm need for their survival during that time. But while the woman’s body can help sperm on their way to meet the egg, it can also hinder it their survival as well.

An egg has 24 hours to be fertilised, otherwise it dies

But even so, sperm really only have about 24 hours to fertilise an egg once it is released. After 24 hours, if the egg isn’t fertilised it will die, so really, it doesn’t matter how long the sperm can survive for if the egg has already died.

Poor sperm have to contend with many things when they enter a woman’s body. A woman’s vagina is coated in acids, to protect her from infections and bacteria, but it is also lethal to sperm. This is why within minutes and hours, most of the 300-500 million sperm that set off in search of the egg will be dead. Only a few million will survive to swim through cervix.

Climax helps with getting sperm into the uterus

A woman’s body can help to get the sperm going up into to the cervix though. Through climax (orgasm) contractions are created that can help pull sperm up and into the uterus. Through these contractions the cervix is dipped time and time again into a pool of waiting sperm and this then helps carry the sperm up into the second stage of their journey through the uterus and then up into the tubes.

Only a small number is sperm survive the journey

Once inside the female reproductive tract, the sperm cells must swim through the cervix and into the uterus to reach the fallopian tubes and then on to find the female egg. It is a very long journey for sperm to make and very few survive. Many get lost inside the uterus and some are attacked by the woman’s immune system along the way. By the time the survivors make it to the fallopian tubes to have a rest, there will only be less than 20 or more left to make the final journey.

After the sperm have a rest in the tubes and actually feed off some of the nutrients in the tubes many more will die, or be lost inside the tubes and by the time the final sperm reach the egg, there will be less than 10 single sperm left. Only one may then go on to fertilise the egg and an embryo is then started to be created.

All men should have there sperm quality tested

This is why all men need to have their sperm quality checked by a proper andrology lab and some men will need further testing of the DNA (DNA fragmentation analysis) and further genetic testing if the semen results are poor.

This should all be done prior to trying to conceive, as 50% of fertility issues are related to men. If a man has any of these risk factors, he should try to change them at least 3-4 months before trying to conceive, since that is how long it takes for sperm to fully mature. Some men may need longer than this, depending on what is causing their sperm to be of poor quality.

I will discuss some more myths and facts around sperm and what the most important parameters are to look at with sperm, in some later posts.
