Anti-Mullerian Hormone (AMH) Serum Test

 AMH is expressed by granulosa cells of the ovary in the reproductive age and controls the formation of primary follicles by inhibiting excessive follicular recruitment by FSH. It therefore has a role in folliculogenesis, and some authorities suggest it is a measure of some aspects of ovarian function useful in assessing conditions such as polycystic ovary syndrome and premature ovarian failure.

AMH production by the Sertoli cells of the testes remains high throughout childhood but declines to low levels during puberty and adult life. AMH measurements have become widely used in the last few years in the evaluation of testicular presence.
