Anti-Mullerian Hormone (AMH)

Definition - What does Anti-Mullerian Hormone (AMH) mean?

Anti-mullerian hormone (AMH) is a hormone produced by immature eggs in the ovary that can be used to attempt to measure the pool of immature eggs remaining.

Low levels of AMH are indicative of low egg supply and can predict a woman’s response to in vitro fertilization (IVF). They can also be a part of assessing fertility disorders such as premature ovarian failure (POF) and polycystic ovary syndrome (PCOS).

FertilitySmarts explains Anti-Mullerian Hormone (AMH)

Women are born with a set number of immature eggs within each ovary. Ideally, at puberty and the onset of menstruation, one egg a month is matured and released through a menstrual cycle until a woman reaches menopause.

AMH is produced by these immature eggs and released into the blood in levels that can be used to estimate the level of ovarian reserve or the number of eggs a woman has remaining. Women undergoing in vitro fertilization (IVF) with elevated AMH are more likely to have a favorable response as it is an indication there is a good number of eggs available for extraction.

Low levels of AMH outside of menopause indicates a low ovarian reserve and might indicate polycystic ovary syndrome (PCOS), where a woman has most of her eggs replaced by cysts or premature ovarian failure where the ovary does not respond favorably to hormones.
