The Anti-Müllerian Hormone (AMH) test is a medical test that measures the level of anti-Müllerian hormone in a woman's blood, which is primarily produced by follicle cells in the ovaries. This test is mainly used to assess ovarian reserve, which is the total number of eggs available to a woman. AMH levels are an important indicator of a woman's fertility, as high levels suggest a good ovarian reserve, while low levels indicate a potential decrease in fertility. This information can help doctors guide treatment options for women experiencing difficulty conceiving or those planning to delay pregnancy. It is recommended to conduct this test during a specific period of the menstrual cycle, and it is generally considered a safe and quick test with results available within a few days.
