The anti-müllerian hormone (AMH) level in the blood is measured in this test. Both males and females produce AMH in their reproductive tissues. The function of AMH and whether or not your levels are normal are determined by your age and gender. AMH plays a critical part in the development of a baby's sex organs while he or she is still in the womb. A baby's reproductive organs begin to mature during the first weeks of pregnancy. The kid will be born with the genes to be either a male or a female (XY genes) (XX genes).
