Also known as:
Anti-Müllerian hormone, ovarian reserve test
A marker of how many small follicles remain. Useful for IVF planning and PCOS, not a fertility verdict.

VIDEO LESSON
What it measures
AMH is made by small growing follicles, so it tracks the size of the remaining follicle pool. It declines steadily with age.
When it helps
• Planning IVF and predicting response to ovarian stimulation
• Supporting a PCOS diagnosis in adults, where the 2023 guideline accepts it in place of ultrasound
• Counseling before treatments that can damage the ovaries
What it can't tell you
AMH does not predict natural fertility well. In a prospective study of women trying to conceive, low AMH was not linked to a lower chance of pregnancy. It also cannot pinpoint when menopause will arrive.
Good to know
AMH can be measured on any cycle day. Hormonal contraception may lower it modestly, and levels vary between assays.
