PCOS: Youthful Infertility Balanced by Late-Blooming Ovaries
About seven percent of reproductive-age women have PCOS, which features irregular periods, high levels of male hormones and greater numbers of developing follicles, or cysts, on the surface of their ovaries. In a normal ovary, a few follicles appear each month, one or two of which mature and release an egg; the rest die off. Women with PCOS ovulate less often because their extra follicles interfere with normal hormonal activity and stop follicles maturing past a certain stage, lowering their fertility.
A new study out of Sweden, however, found that women with PCOS had just as many pregnancies and birthed as many babies, on average, as PCOS-free women of the same age. Some of the women with PCOS in the study had been treated for infertility, but more than two-thirds had become pregnant without such help.
The study observed that as women with PCOS age, their ovaries showed signs of being more active, with better hormone levels and more eggs available, indicating that as women with PCOS get older, their chance of getting pregnant may be higher.
