Miscarriage rates following IVF increased in women with PCOS

Miscarriage rates following in-vitro fertilization are increased in women with polycystic ovaries and reduced by pituitary desensitization with buserelin.

Human Reproduction, Vol. 8, No. 6, pp. 959-964, 1993© 1993 European Society of Human Reproduction and Embryology

To assess the risk of miscarriage after in-vitro fertilization (IVF) with respect to age, cause of infertility, ovarian morphology and treatment regimen, a retrospective analysis was performed of the first 1060 pregnancies conceived between June 1984 and July 1990 as a result of 7623 IVF cycles.


Superovulation induction was achieved with human menopausal gonadotrophin (HMG) and/or purified follicle stimulating hormone (FSH) together with either clomiphene citrate or the gonadotrophin hormone-releasing hormone (GnRH) agonist buserelin, the latter either as a short ‘flare’ regimen or as a ‘long’ regimen to induce pituitary desensitization.

There were 282 spontaneous abortions (26.6%) and 54 ectopic pregnancies (5.1%). The mean age of women with ongoing pregnancies was 32.2 (SD 3.9) years compared with 33.2 (SD 4.1) years in those who miscarried, which were significantly different (P = 0.008). There was no relation between the miscarriage rate and the indication for IVF.

The miscarriage rate was 23.6% in women with normal ovaries compared with 35.8% in those with polycystic ovaries [P = 0.0038, 95% confidence interval (CI) 4.68–23.10%]. There was no difference in the miscarriage rate between treatment with HMG or FSH.

Women whose ovaries were normal on ultrasound were just as likely to miscarry if they were treated with clomiphene or with the long buserelin protocol. Those with polycystic ovaries, however, had a significant reduction in the rate of miscarriage when treated with the long buserelin protocol, 20.3% (15/74), compared with clomiphene citrate, 47.2% (51/108) (P = 0.0003, 95% CI 13.82–40.09%).

Miscarriage Myths Persist Despite Prevalence Of Medical Information

ScienceDaily (Dec. 7, 2007) — More than a third of women surveyed about their beliefs surrounding miscarriage and birth defects said they thought that a pregnant woman's foul mood could negatively affect her baby.

One in four of these women thought a pregnant woman's exposure to upsetting situations could hurt her unborn child, and one in five believed excessive exercise could cause a woman to miscarry.

Despite those beliefs, relatively few of the women surveyed blamed mothers for a poor pregnancy outcome. Ten percent suggested pregnant women are responsible for their miscarriages, and 3 percent said mothers should be blamed for their babies' birth defects. Women with less formal education were more likely to hold mothers responsible for bad pregnancy outcomes.

The recent Ohio State University study points to the persistence of folklore surrounding pregnancy despite advances in medical interventions and evidence that most miscarriages and defects result from circumstances beyond a woman's control, said study author Jonathan Schaffir, a clinical assistant professor of obstetrics and gynecology at Ohio State.

“The survey shows that a sizable proportion of the population believes maternal thoughts and actions contribute to adverse fetal outcomes – but despite these feelings, few assign responsibility to the mother,” Schaffir said. “I think it's kind of amazing that people out there still believe that a pregnant woman seeing something frightening could cause her baby to have a birthmark. That was an 18th-century belief and it's still circulating, even today.

“I had a call not long ago, before Halloween, from a pregnant woman asking if it would be OK to go to a haunted house. I told her it was fine.”

Most miscarriages result from genetic or chromosomal abnormalities in the fetus, or from medical complications relating to hormonal imbalances or problems with the uterus or placenta, Schaffir noted.

“Most of these things are beyond anyone's control and can happen to anyone,” he said. “In general, minor day-to-day experiences don't have an effect on whether a pregnancy is successful or not.”

Exceptions, of course, would include the abuse of alcohol or drugs during pregnancy, which can lead to complications, he said.

Schaffir surveyed 200 women by circulating a questionnaire in the waiting area of a Midwestern obstetrics and gynecology clinic. He asked respondents to rate their level of agreement with common folk beliefs about prenatal influences on fetal outcomes, and whether or not respondents had a history of an adverse pregnancy outcome.

The folkloric beliefs the participants considered included whether a pregnant woman's stress, bad mood, viewing of upsetting TV programs or attending upsetting events, excessive exercise, unfulfilled food cravings, or exposure to ugly or frightening sights could have a negative effect on her unborn baby. An additional item for consideration was whether a baby's appearance is determined at conception. Two final entries gauged whether respondents thought miscarriages and birth defects should be blamed on mothers.

Six percent of respondents thought a mother's unfulfilled food cravings could have an adverse effect on a fetus and 5 percent believed a pregnant woman's exposure to a scary sight could hurt her unborn baby. Thirty-eight percent of the women surveyed believed that a baby's appearance is determined at conception. More than three-fourths (76 percent) of women believed stress could cause a bad pregnancy outcome.

Schaffir expected women who had miscarried or delivered a baby with serious birth defects to be more inclined to believe that they had somehow contributed to their misfortune. But the survey results did not support his expectation. Instead, the level of a woman's education appeared to affect her belief system, with a lower level of education resulting in a higher likelihood of blaming mothers for bad pregnancy outcomes.

“Women with less education were more likely to think problems were a mother's fault. This isn't necessarily because women learn more about pregnancy during formal education, but reflects that women who have pursued higher education might read more and rely on more stringent sources for information about what they choose to believe. They might be more scientifically guided,” he said.

Education levels among respondents included some high school (33 women), high school graduate (46), some college (59), college graduate (40) and graduate school (19). Women with less education were also more likely to believe that stress can adversely affect pregnancy.

The pregnancy history of survey respondents appeared to have no bearing on beliefs in any but two areas. Women with no history of bad pregnancy outcomes were more likely to believe a bad mood or a fright could lead to birth defects or miscarriages, suggesting to Schaffir that women who had received medical care for an adverse pregnancy outcome were provided with more fact-based explanations for what had happened to them.

The mere existence of these beliefs suggests there is an opportunity for education in the exam room, Schaffir said.

“I do think there is room for educating women more, particularly those who have less formal education, to prevent them from feeling any guilt in association with their pregnancy,” he said. “Health care providers can reassure patients that these ‘old wives' tales' should not contribute to any feelings of personal responsibility.”

The survey respondents' belief that stress can affect pregnancy outcomes mirrors more conventional societal beliefs as well as a growing body of research about the effects of stress on health, Schaffir noted. But because he was gauging opinions and not facts about pregnancy, he did not explore that finding.

“A majority of people agree that stress can contribute to a bad outcome, and for more long-term behavioral disorders, it's not all that farfetched. But I was studying what people believe rather than what actually causes poor outcomes,” he said.

The study appears online in the journal Archives of Women's Mental Health.

Lower your miscarriage risk with new tests, treatments

When Kori Morrison had her first miscarriage, she and her husband, Tom, were upset but still hopeful. After all, she knew that 15 to 50 percent of all pregnancies end in miscarriage, and most of these women who've miscarried go on to have healthy babies. But in the next eight years, Morrison had four more miscarriages. Sadness and self-blame set in. "I wondered if I was eating the wrong things, if I was overstressed, or, worst of all, if my body just wasn't cut out for pregnancy," she says.

Morrison was eventually found to have a hormone imbalance: Low progesterone during pregnancy kept her uterus from nourishing the embryo. With treatment, she went on to have four children.

Although Morrison went through agony for years before discovering what was wrong, her story illustrates that there are ways to identify what causes miscarriages and what can be done to prevent them. Important to know because, while most women will go on to have a successful pregnancy, about 5 percent are likely to lose another baby. And the use of assisted reproductive technology such as in vitro fertilization (common among women 35-plus) seems to boost miscarriage risks even more.

1. Do a little detective work

When you're planning to get pregnant, your first move should be a careful prepregnancy checkup to reveal potential risk factors like diabetes-related problems, high blood pressure, polycstic ovary syndrome, fibroids, or thyroid abnormalities -- all of which are mostly treatable, says Mary Stephenson, M.D., professor of obstetrics and gynecology and director of the recurrent-pregnancy-loss program at the University of Chicago Medical Center.

Health.com: Simple steps can help when you're having trouble getting pregnant

Go over your medical history with your doctor, and also mention any medications, herbs, and supplements you are taking. You might learn something about potentially risky non-prescription meds such as ibuprofen or herbs such as ginkgo. Even taking a little time to discuss a family history of miscarriages with your doctor might uncover a correctable problem.

2. Stop the stress

We've all heard that being stressed isn't a good thing if you're trying to get pregnant. That's also true of trying to stay pregnant. British researchers recently found that feeling happy, relaxed, or in control is linked to a 60 percent reduction in a woman's miscarriage risk. What helps when you can't kick back with a glass of wine? Gentle workouts, dining with friends, or watching your favorite TV show might work (stick with The Office instead of nerve-janglers like 24 or ER).

Health.com: The Pill is dangerous, and other myths

And what about sex? If you've had a miscarriage in the past, says Jonathan Scher, M.D., assistant clinical professor of obstetrics and gynecology at Mount Sinai Medical Center in New York, it's probably best to skip nookie during your first trimester, when a hormone in semen may stimulate contractions. It's OK later, after the embryo is fully implanted.

Health.com: Is your fertility window closing?

3. Do some chromosome testing

After a miscarriage, a chromosome analysis of fetal tissue can provide some useful information, says Scher.

The test can reveal if there was an unavoidable chromosome problem -- the cause of as many as 50 percent of miscarriages. If the test result is abnormal (the tissue has an abnormal number of chromosomes), it's good news. This is a random event, and the chance of it happening again is no higher than normal. Time to try again. A normal test result, however, may require further investigation (there's more information on this in "Take a Few More Tests," below).

Unless you insist, you may not be offered chromosome analysis. "It's the most important thing we can do," Stephenson says, "But, unfortunately, it's very seldom done."

Why? Medical guidelines don't recommend it unless you've had multiple miscarriages. Even then, if you're healthy, doctors might beg off. But Scher and Stephenson advise any woman who has two or more miscarriages to get the test.

Health.com: A calendar method that works

4. Take a few more tests

- MayoClinic.com: Health Library
- Healthology: Health Video Library


If the chromosomes are normal and it's your second or third miscarriage, there's a good chance you have a fixable problem. But you won't find out without additional tests. You might be screened for a genetic tendency for blood clots, a weak cervix, a hormonal imbalance, or even an autoimmune problem such as lupus. If you have a blood-clotting disorder, anticlotting medication may cut your risk of miscarriage by up to 75 percent. If it's a weak cervix, a stitch applied at the end of the first trimester can prevent the cervix from opening early and starting premature labor.

To uncover these kinds of problems, you may need to go to a specialized, recurrent-pregnancy-loss clinic, Stephenson says. Most important, though, keep pushing for answers. That's what Darci Klein did after suffering three miscarriages, including the loss of twins at 20 weeks. Eventually, tests showed she had an inherited blood-clotting disorder and a weak cervix. After treatment -- injections of a blood thinner and a cervical stitch -- she carried a pregnancy to term and gave birth to a healthy baby boy. "You don't ever get over losing a child," says Klein, author of "To Full Term: A Mother's Triumph Over Miscarriage." "But you need to ask for testing."

A loss that is hard to bear

As soon as a pregnancy is detected, each prospective parent looks forward to and plans for their new arrival. If the pregnancy is lost this is often considered a death within the family. The loss of a pregnancy can be devastating for a couple regardless of the number of children in the family or the cause for the loss. Many couples blame themselves for their pregnancy loss. It is very rare that either member of the couple has done anything that would result in a pregnancy loss.

Recurrent pregnancy loss (RPL) (recurrent abortion; habitual abortion) is typically defined as three or more consecutive pregnancy losses that occur usually before 20 weeks of gestation.

Although approximately 25 per cent of all pregnancies result in miscarriage, less than five per cent will experience two consecutive miscarriages, and only one per cent will experience three or more.

Causes

The causes for RPL could be divided into two major categories namely, foetal and maternal.

Foetal causes: These include the genetic composition of the foetus. It is uncommon to find an inherited genetic cause for recurrent miscarriages. A chromosome analysis performed from the parents' blood identifies an inherited genetic cause in less than five per cent of couples.

In contrast to this, many early miscarriages are due to the denovo (by chance) occurrence of a chromosomal abnormality in the embryo. About 60 per cent or more of early miscarriages may be caused by a random chromosomal abnormality, usually a missing or duplicated chromosome.

Maternal causes: These include abnormalities in the environment in which the foetus develops. The chance of miscarriages increases as a woman ages.

After the age of 40 years, more than one-third of all pregnancies end in miscarriage. Most of the embryos have an abnormal number of chromosomes.

Distortion of the uterine cavity is considered to cause about 10 to 15 per cent of recurrent miscarriages. The most common abnormality is a uterine septum i.e., a partition of the uterine cavity. The diagnosis can be made by x-rays or ultrasound scan of the uterus.

The other congenital abnormalities include a double uterus, and a uterus in which only one side has formed. Scar tissue in the uterine cavity, large uterine fibroids and polyps could result in pregnancy loss. In the second trimester, a weak cervix can become a recurrent problem. Most of these conditions can be surgically treated.

Immunological Causes: Two major categories of immunologic causes of RPL are autoimmune, in which the woman's immune system attacks her own organs and tissues, and alloimmune, in which the immune system attacks tissues considered foreign.

Autoimmune disease or dysfunction may play a role in up to 10 per cent of RPL. Phospholipids are molecular building blocks that form a large portion of the walls of cells in the body, which includes placental cells.

Antiphospholipid syndrome (APS) is an autoimmune dysfunction where antibodies are produced against phospholipids that form part of the blood vessel walls.

Hence clots are produced in the placental blood vessels blocking off the blood supply to the foetus thus producing foetal demise.

Without treatment, couples with APS have a poor chance of carrying a foetus to term. Low dose aspirin and low molecular weight heparins definitely help in this sub-group of patients.

Allo immune dysfunction

Normally a person will reject dissimilar (non-self) tissues or structures from the body using the immune system.

In pregnancy, the placenta and growing embryo are not entirely self, but rather are a result of both the maternal and paternal genetic heritages. The placenta has a privileged relationship with the pregnant woman that allows for it to escape rejection. When this mechanism is disturbed, it can result in foetal loss.

Miscellaneous : Causes related to an action of the mother are very uncommon but can include exposure to chemical toxins, X-rays in early pregnancy and rarely heavy smoking and alcohol abuse. Medications taken during pregnancy should be reviewed with an obstetrician.

Treatment: The two main treatment options are as follows: Leucocyte immunisation with paternal or donor blood cells, or immunoglobulin treatment with IV injections, which is very expensive. This should be conducted only in research settings, as their benefits are largely unproven.

Poorly controlled diabetes increases the rate of miscarriage.

Women with diabetes improve pregnancy outcome if blood sugars are controlled before conception. Women who have insulin resistance, such as obese women and women with polycystic ovaries also have higher rates of miscarriages.

The second half of the menstrual cycle, that is the time from ovulation up to the next period, is called the luteal phase. This phase is characterised by high circulating levels of a hormone called progesterone in the blood.

Progesterone, which is produced by the ovary after release of an egg (ovulation), is necessary for a healthy pregnancy.

Inadequate levels of progesterone, often called as luteal phase deficiency may cause repeated miscarriages. This concept is still under controversy and needs more evidence to prove the absolute necessity of progesterone for the development of a strong pregnancy. If an inadequate progesterone effect is documented or believed to exist during the luteal phase of the menstrual cycle, then either supplemental progesterone (either as oral tabs, vaginal pessaries, vaginal gel or injections), or supplemental HCG (human chorionic gonadotrophins) as injections every few days following ovulation to enhance the ovary's own progesterone productions are treatment options.

Estrogen for Miscarriage

Interesting that they were looking at estrogen even as far back as 1946!

Monday, Apr. 01, 1946 - Three successive spontaneous abortions are an almost infallible sign that a normal pregnancy is unlikely without medical aid. Obstetricians seeking the cause of such abortions have found many. Among them: external, physical influence (hot baths, long train rides, falls); malformation of internal organs; deficient hormone activity.

Manhattan Obstetrician Raphael Kurzrok believes that a large number of miscarriages are caused by "genital hypoplasia" (malformation plus deficient hormone activity). His analysis: in some women, because of insufficient output of estrogen (a female hormone) during pregnancy, expansion of the uterus fails to keep pace with growth of the fetus. Rupture of the membrane and miscarriage result.

To genital hypoplasia sufferers who desperately want to become mothers, Dr. Kurzrok holds out new hope: hormone therapy. In the current New York State Journal of Medicine he reports on the treatment of 42 women with previous histories of repeated miscarriages. After a daily dose of estrogen throughout the months of pregnancy, 39 gave birth to normal children; two had miscarriages for other reasons than genital hypoplasia, one for an undetermined cause.

Sensitivity to hormones linked to miscarriage

Could a heightened sensitivity to female hormones cause miscarriage? A small study found that women with recurrent miscarriage show a hypersensitivity to oestrogen and progesterone in skin tests.

The findings could lead to novel treatments for “unexplained” miscarriage, but they also call into question some current, controversial treatments for the disposition, including injecting women with progesterone.

Miscarriages often occur because the embryo has a genetic defect. But several consecutive miscarriages are unlikely to be the result of random genetic anomalies.

Instead, these can be caused by abnormalities in the uterus, unusual hormone levels, clotting disorders or lupus in the mother. “But in at least half of the cases, we can’t find the reason. It’s frustrating,” says Mark Walker at the University of Ottawa in Canada, who was not involved in the study.

Reaction time
Researchers at the Sheba Medical Center in Tel Hashomer, Israel, wanted to get to the bottom of these unexplained miscarriages. The team tested the immune reaction of women with recurrent early pregnancy loss to progesterone and oestrogen – the hormones that regulate pregnancy. Previous studies had shown a connection between miscarriage and unusual immune system responses, but none had looked at the role of these sex hormones, the researchers say.

The researchers injected the hormones into the skin of 29 women who had experienced at least three unexplained miscarriages, and 10 women who had successfully carried a baby to term and never had a miscarriage.

The injections sites, and the arm, were monitored for signs of redness and swelling. All but three of the women in the first group showed hypersensitivity to one of the two hormones, and 17 women showed hypersensitivity to both. None of the women in the control group had a reaction to the test.

“This is really novel,” says Walker. “It’s a small sample size but if the results are that profound, it definitely warrants more research.”

Killer cells
“It opens prospects as far as diagnostics and treatment,” says Alek Itsekson, who led the study. He thinks hypersensitivity to these hormones might be increasing the numbers of immune system cells called natural killer cells. These normally surround the embryo harmlessly as it grows, but an increase in their amount has been linked to early miscarriage (see Major flaw in miscarriage test).

Steroids have been tested as a possible treatment for this problem but they can have potentially dangerous side effects (see Is steroid treatment for miscarriage safe?). Knowing the mechanism behind the negative immune reaction to progesterone and oestrogen might lead to better options, the researchers say.

Itsekson’s team is looking at the same reaction in rats to try to understand exactly how the immune system is responding. They are also conducting follow-up clinical trials in humans.

The results call into question a practice sometimes used to treat recurrent miscarriage, in which injections of progesterone are given to women who have less of the hormone than normal. The usefulness of these injections is already controversial, the researchers say, and if the women are hypersensitive to progesterone the treatment may have unknown side effects.

Hypersecretion of luteinising hormone, infertility, and miscarriage.

The relation between prepregnancy follicular-phase serum luteinising hormone (LH) concentrations and outcome of pregnancy was investigated prospectively in 193 women with regular spontaneous menstrual cycles. The group included 26 nulliparous and 167 multiparous women with various obstetric histories.

Of the 147 women with LH concentrations of less than 10 IU/l (normal LH group) 130 (88%) conceived, whereas only 31 (67%) of the 46 women with LH values of 10 IU/l or more (high LH group) did so. In the high LH group, 20 (65%) of the pregnancies ended in miscarriage, whereas only 15 (12%) of pregnancies in the normal LH group did so.

The adverse effect of a high prepregnancy LH concentration on fertility and outcome of pregnancy was seen in primigravidae, women with previously successful pregnancies, and women with a history of recurrent miscarriage.

These data indicate an important role for hypersecretion of LH before conception in miscarriage. This finding offers the possibility of a simple predictive test for women before pregnancy, and could also be used to identify patients with an endocrine abnormality that can be remedied

Hormones predict miscarriage risk

Doctors may be able to predict which women are at high risk of miscarriage by measuring their hormones, say researchers.

Women likely to miscarry tend to have lower blood levels of hormones produced by the placenta, scientists at University College London found.

In the future, it might be possible to correct the cause of these imbalances to prevent miscarriage, experts hope.

Recurrent miscarriage - three or more in a row - affects one in 100 women.

Recurrent miscarriage

Doctors had previously noted that levels of a certain hormone, called inhibin A, were lower in failed IVF pregnancies than in successful IVF pregnancies.

Professor Eric Jauniaux and his team, with funding from the Wellcome Trust, set out to investigate whether this hormone and others produced by the placenta might be useful markers of early pregnancy loss.

They took blood samples from 37 pregnant women, including women with a history of unexplained recurrent miscarriages, women with no history of miscarriage and women who had had one miscarriage in the past.

At as early as six weeks' gestation, levels of three placental hormones - inhibin A, hCG and oestradiol - were up to four times lower in the women who went on to miscarry compared with the women who subsequently had a live birth.

These hormones are known to be critical for the embryo's nourishment and development.

Professor Jauniaux said: "If we are able to identify these clear hormone variations early enough, we believe there is a real window of hope for the development of preventative therapies for these patients."

Work by other researchers supports the idea that inhibin A might be a good marker for predicting pregnancy outcome.

But a team of Australian researchers found it was not helpful.

Future studies

Professor Jauniaux' team acknowledge that more research is needed and are planning further investigations involving many more women.

A spokeswoman from the Miscarriage Association said: "We really welcome this research, particularly because it might lead to the development of treatments to prevent recurrent miscarriage.

"Although it is important to pick up miscarriages earlier, that is nowhere near as important as being able to possibly develop treatments that might prevent it.

"I know it's early days yet, but it does look a promising line of research.

"Recurrent miscarriage is very distressing and it is not uncommon. This type of research gives women who suffer from recurrent miscarriage real hope for the future."

More on Progesterone....

On Monday, we spoke about the benefits of progesterone and how easily it is stolen away due to stress. Unfortunately there is a lot of misinformation when it comes to properly measuring progesterone and estrogen levels. Just as scripture teaches, “my people are being destroyed by lack of knowledge,” we hope we can help women better understand why they haven’t been getting the results they have been looking for – even after they have been told by their doctor…. ”everything looks normal.”

Measuring those Hormones

Often times women will tell me they had their hormones tested and were told everything was normal. Unfortunately a one time blood or saliva sample doesn’t give an accurate measurement to those hormones due to the fact that they fluctuate so much in a month. A more accurate picture and diagnosis can be made when several hormone samples in a month can be mapped out to determine if there are any abnormal hormonal variations.

I encourage anyone who is struggling with infertility, PMS, or other hormonal issues to taking anywhere from 7-11 saliva samples to get a clear and accurate picture of your monthly cycle. When you map out your monthly cycle, you can easily see if your hormones are ‘truly’ staying within their normal range. If you are struggling with infertility, it is very important to also measure your LH and FSH in addition to estrogen and progesterone.

Estrogen and progesterone tell us if your ovaries are getting the job done. While the LH and FSH are more indicative of the communication between your brain (pituitary) telling your ovaries to start the ovulation process.

The Stress Connection

Low levels of progesterone are often attributed to your adrenal glands stealing your progesterone. This is why it is recommended to first measure adrenal function and see how much stress we are truly placing on our body. The best way to measure your adrenal function is with a saliva test that measures both cortisol and DHEA.

Cortisol and DHEA are direct indicators to how much stress you are placing on the body. The constant demand for cortisol will eventually exhaust the adrenal glands and disrupt the production of your progesterone, estrogen, testosterone and DHEA. It is a basic cause and effect… and you will never get your reproductive hormones back to normal if your adrenal glands are burnt out.

A good ‘adrenal stress panel’ will include 4 cortisol measurements, 2 DHEA measurements as well as a measurement for your insulin levels. Measuring insulin is helpful and indicative to adrenal function, because high levels of cortisol trigger increased insulin which is associated with obesity, cravings, diabetes, high blood pressure, and heart disease.

The healing process is more than swallowing a handful of supplements and begins by restoring normal function to the body. If stress is throwing your body out of balance, check to see if your adrenals need support. If they are - support them and then it will be easier to rebalancing those reproductive hormones.

Progesterone: A Women's Best Friend During Pregnancy

Infertility, miscarriage and C-sections are fast becoming important topics of discussion for anyone wanting to become pregnant. The rate of infertility, miscarriages and C-sections are at an all time high. Add everyday worry and anxiety to the equation and you will easily see how stress can contribute to these problems.

Stress, as it does in so many areas of our life interferes with the reproductive process and a major cause for infertility and miscarriages. The reason is simple, lack of progesterone.

The word itself, progesterone means “for gestation,” meaning we need this hormone, in its right balance if we want be become pregnant and stay pregnant. Progesterone nourishes the uterine lining in preparation of the implanted fertilized egg. It is progesterone that continual feeds and nourishes the uterus during pregnancy. Unfortunately, constant stress causes a decrease in your progesterone levels.

When you are constantly in that “fight or flight” mode because of stress your adrenal glands will produce additional cortisol and adrenaline. This is a normal bio-chemical process. The problem is that in order to make cortisol, your adrenal glands need progesterone. This causes your progesterone to be used in making your stress hormones as opposed to what it is designed to do, which is support your pregnancy.

The adrenal glands can not make cortisol without progesterone. It is literally a raw material needed by your adrenal glands to make cortisol. It’s often referred to as the ‘progesterone steal’ because your body will steal however much progesterone it needs to make cortisol. This is one of the primary reason some women are having a hard time with infertility and miscarriages, they don’t have enough progesterone available to conceive or maintain a pregnancy.

The body is designed for survival and when you are constantly in that “fight or flight” mode it is more important for the body to run away from the saber-tooth tiger than it is to have a baby. The constant demand for cortisol is going to reduce your levels of progesterone. Inadequate levels of progesterone not only interferes with the reproductive process, but it is another reason so many women struggle with PMS, hot flashes, night sweats, etc…. their progesterone is being stolen away to make cortisol. This whole progesterone steal process causes a deficiency, but also affects the balance of progesterone to estrogen and testosterone.

Supplementing with progesterone (I prefer sublingual progesterone over topical creams) can do wonders for so many women who are struggling with infertility, miscarriages, PMS, hot flashes, night sweats and other hormonal imbalances . Yet I always encourage my patients to identify where the stress is coming from and support those exhausted adrenal glands.

If we merely add progesterone without nourishing those adrenal glands, we are going to always have to supplement with progesterone. But if we strengthen our adrenal glands and manage our stress, we allow the adrenal glands to function the way they are designed to. Most importantly – you can never get your progesterone levels back to normal without first supporting and nourishing those exhausted adrenal glands.

Next time we will discuss how to accurately measure your hormone levels and how to support your progesterone.
