Anti-Müllerian hormone (AMH)

The anti-Müllerian hormone (AMH) is produced by the growing eggs in the ovaries and represents your egg supply.

AMH should always be interpreted in combination with age. This is because AMH is not particularly good for determining current fertility. Rather, the AMH is the best parameter for future fertility: the lower the age-specific AMH, the earlier the menopause begins.

Women with an AMH at the 50th percentile (meaning that 49% of all women at this age have a lower AMH value and 50% of all women at this age have a higher AMH value) usually reach menopause at the age of just under 52. Women with an AMH at the 25th percentile usually enter menopause at age 50. Women with an AMH at the 75th percentile usually reach menopause at age 54.

Perimenopause begins about 10 years before menopause. Important: Perimenopause, unlike menopause, is a defined moment. Menopause is the time when there has been no menstruation for a year.
