Antimullerian Hormone (AMH Plus)

Anti–Müllerian hormone (AMH) is very important during the development of the male foetus as it is essential for the formation of male reproductive organs. In males, AMH is generated within cells in the testes, is detectable at birth in males and levels rise rapidly in infancy. After puberty, the levels of AMH decline in men.
In females, small amounts of AMH are produced by developing follicles in the ovaries. Levels are very low at birth, but increases significantly at puberty reaching a peak in early adulthood. As women age, the number of follicles (which produce AMH) decreases and so the level of AMH declines and becomes undetectable after the menopause. AMH levels in women therefore reflect the declining ovarian function, and its measurement is said to indicate ovarian reserve.
