When doctors want to determine a woman’s ovarian reserve, they measure her level of follicle stimulating hormone (FSH). When it’s high, it generally means she doesn’t have a lot of eggs left in her ovaries. This typically is the case as a woman ages. But even younger women can have a high FSH level. And while it might mean they’ll experience menopause early, it still may be possible for them to get pregnant. Even though the number of good eggs is diminished, the quality of the eggs that remain should still be good. Doctors say they’ve seen patients in their early thirties with significantly elevated FSH levels who have still been able to have babies.
