Anti Müllerian Hormone: More than a biomarker of female reproductive function

Anti-Müllerian hormone (AMH), known for its role during sexual differentiation, is a dimeric glycoprotein that belongs to the transforming growth factor-β (TGF-β) family. AMH has recently been identified as a reliable marker of ovarian reserve that can help predict early ovarian follicle loss and menopause onset. AMH levels also reflect the effects of damaging gynecologic surgeries or gonadotoxic treatments such as chemotherapy on ovarian reserve. Furthermore, AMH participates in the diagnosis of certain diseases such as granulosa cell tumors or Polycystic Ovary Syndrome (PCOS). Currently used to establish patient profiles and predict ovarian response to stimulation, its role in ART techniques is crucial. Nevertheless, AMH appears to be a weak independent predictor of qualitative outcomes such as implantation, pregnancy, and live birth. As the reliability and reproducibility of AMH dosage have raised many doubts due to different existing standards and thresholds, an international consensus is still expected to improve AMH measurement and interpretation.
