What Is AMH (Anti-Mullerian Hormone)?

Anti-Mullerian Hormone (AMH) is a protein hormone produced by granulosa cells in small ovarian follicles. AMH blood levels serve as one of the most reliable markers of ovarian reserve: the remaining egg supply.

Clinical significance

AMH levels help fertility specialists predict ovarian stimulation response and tailor IVF medication protocols. Low AMH (below 1.0 ng/mL) suggests diminished ovarian reserve and may predict fewer eggs at retrieval. High AMH (above 3.5 ng/mL) may indicate a higher risk of OHSS during stimulation.

Common confusion

AMH measures egg quantity, not quality. A patient with normal AMH but advanced age may still have a high proportion of chromosomally abnormal eggs. Age remains the strongest predictor of egg quality.
