Does Aging Increase Fertility in PCOS?

Infertility.  Out of all of the symptoms of Polycystic Ovarian Syndrome (PCOS), this is nearly always the first on the list.

It seems obvious that it would be the most common symptom, right? Polycystic Ovarian Syndrome has “ovary” right in its name. Women with PCOS must be infertile.

NOT SO FAST…now a study from Miriam Hudecova and colleagues at Uppsala University in Sweden [i] turns this maxim on its head.

Hudecova’s study indicates that women with PCOS not only have roughly the same amount of spontaneous pregnancies, but that their rates of miscarriage are not increased.  Her research concludes this to be true because of a couple of hidden benefits of PCOS for women who wish to have children later in life.

First, women with PCOS may begin life with more eggs than women without PCOS.

In fact, “An important biopsy-study showed a much increased density of follicles at primary stages in polycystic ovaries compared with normal ovaries, suggesting that women with polycystic ovaries may actually be endowed with a larger ovarian reserve at birth[ii]” That means that as we age, we have more eggs left over than women without PCOS.  This increased ovarian reserve, together with other factors (discussed below) mean older women with PCOS have a better chance of pregnancy than their age matching non-PCOS counterparts[iii].

Second, ovarian aging naturally results in follicle loss.

This bodes well for women with PCOS since the major cause of infertility in women with the syndrome is that they have greater numbers of follicles or cysts on their ovaries than healthy women. As a result, they ovulate less frequently because these extra follicles interfere with their hormonal activity and prevent just a few healthy follicles from maturing. When aging naturally reduces the number of follicles, the hormonal problems should lessen (if not disappear). This may explain the normalized menstruation cycles reported by some older women with PCOS[iv],[v] .

In addition, the study concludes that, “Thus, in women with PCOS, this age-dependent reduction in the pool of resting follicles may eventually lead to more cycles becoming ovulatory and a catch-up of fecundity.”

Translation? As women with PCOS age (and women without PCOS become infertile because they are running out of eggs and losing follicles they need to ovulate), women with PCOS still have eggs remaining and have a more optimal number of follicles than in their youth.

Finally, the study showed that the rate of miscarriages was not increased in PCOS patients.

These findings are contrary to previous studies[vi],[vii],[viii]. Researchers think the difference is that, in other studies, infertile PCOS patients undergoing assisted reproduction were the only patients studied, whereas the Swedish study included PCOS patients seeking help for other PCOS symptoms such as oligomenorrhoea, hirsutism or infertility.

The study suggests that “factors other than the PCOS diagnosis might contribute to the increased risk of miscarriage reported in prior studies, such as obesity, fertility treatmentv or smoking[ix]. Indeed, in women with polycystic ovaries, but not a full syndrome, miscarriage rates have been reported to be normal[x].

This all comes together as very hopeful news.  It is possible that with a reduction in other factors (like obesity and insulin resistance) that our bodies will naturally come to a “normal” ovulation cycle- just much later than women without PCOS.

Could it be that two perceived negatives (aging and PCOS) can turn out to be a blessing?  Self-care plus Mother Nature may just equal PCOS fertility.

Amy Medling, best-selling author of Healing PCOS and certified health coach, specializes in working with women with Polycystic Ovary Syndrome (PCOS), who are frustrated and have lost all hope when the only solution their doctors offer is to lose weight, take a pill, and live with their symptoms. In response, Amy founded PCOS Diva and developed a proven protocol of supplements, diet, and lifestyle programs that offer women tools to help gain control of their PCOS and regain their fertility, femininity, health, and happiness.

  1. This must be what happened to me. I was irregular my entire life. After having my last baby at 36, I’ve had a regular period ever since. Like clockwork. It’s very strange for me, but I’m not complaining. I’m now 41.
