PCOS delays menopause and extends the fertile window

Published on May 09, 2026 | Translated from Spanish

A recent study reveals that polycystic ovary syndrome (PCOS) delays perimenopause, allowing affected women the possibility of conceiving at more advanced ages. Only 3% of them reach that stage at age 46, compared to a higher proportion in the general population. This is due to a superior ovarian reserve and a different hormonal production that prolongs fertile life.

The biological mechanism behind ovarian delay 🧬

From a technical standpoint, PCOS maintains a greater number of antral follicles in the ovaries, which delays the depletion of the egg reserve. By ovulating less frequently, follicles are preserved for longer, and hormone levels, such as anti-Müllerian hormone, remain elevated. This means the fertile window is extended to ages where other women have already entered perimenopause. The key lies in follicular persistence.

The advantage of having fewer ovulations (and more time) ⏳

So, if you have PCOS, you can take it easy about having children. While your friends see their biological clock speeding up, you have plenty of follicles for a fertile retirement. Of course, you will ovulate fewer times a year, but when you do, it will be like a special event, like a farewell tour concert. In the end, having a polycystic ovary is like having an egg investment fund: long-term profitability.
