Ага, примерно 2 миллиона и в одном цикле обычная женщина (без стимуляции) теряет от 40 до 100 штук.Women are born with around two million follicles. During each ovulatory cycle 40-100 follicles may be used and by the mid-30s this loss speeds up substantially to around 1,000 follicles per cycle being lost, by apoptosis [Figure 1]. Although most women accept that the menopause signifies the end of their fertility, they are generally unaware of how steeply their fertility declines in the years preceding the menopause. On average, fertility begins to decline 15 years before the menopause [4].  http://www.cli-online.com/featured-articles/ovarian-reserve-testing-in-the-assessment-of-age-related-infertility-the-role-of-amh/
