Anti-Mullerian Hormone (AMH) is a hormone produced by the ovaries in women and can be used to indicate the ovarian reserve, which is the number of eggs remaining in the ovaries. AMH is produced by the follicles that contain the eggs within the ovary, and levels can indicate how high or low a woman's ovarian reserve is. However, AMH is not routinely measured in men, and it may only be used by specialist fertility clinics to assess sperm production.
