Anti-Müllerian Hormone (AMH)
Last updated: March 2026 · Medically reviewed by Dr. Adnan Jabbar
Anti-Müllerian Hormone (AMH) is a blood test measuring ovarian reserve — the quantity of remaining eggs. Low AMH indicates diminished ovarian reserve; high AMH is associated with PCOS. AMH does not predict egg quality.
1.0–3.5
Normal AMH range in ng/mL for reproductive-age women (Endocrine Society, 2022)
<0.5
ng/mL threshold indicating diminished ovarian reserve
~25%
Decline in AMH per decade after age 30 (ESHRE, 2023)
What does AMH tell us?
AMH is produced by granulosa cells surrounding small antral follicles in the ovaries. A higher AMH reflects more available follicles — and therefore a larger pool of potentially retrievable eggs. It declines naturally with age as the follicle pool depletes.
In IVF, AMH is used to predict ovarian response to stimulation — specifically, how many eggs are likely to be retrieved. This guides medication dosing and protocol choice. Women with high AMH (often seen in PCOS) need careful stimulation to avoid ovarian hyperstimulation syndrome (OHSS).
Crucially, AMH reflects quantity — not quality. Egg quality is determined by age and other biological factors. A low AMH in a 28-year-old is a different clinical situation than a low AMH in a 40-year-old.
