Anti-Müllerian hormone (AMH) is produced by Sertoli cells in males and granulosa cells in females, serving as a key marker for assessing ovarian reserve and predicting outcomes in Assisted Reproductive Technology (ART). It also aids in evaluating ovarian function in Polycystic Ovarian Syndrome and diagnosing conditions like Ovarian Granulosa Cell Tumors and testicular issues in infants.
