The **Anti-Mullerian Hormone (AMH) test** is a blood test that measures the levels of AMH, a hormone produced by the small, growing follicles in a woman's ovaries. Because the amount of AMH in the blood directly corresponds to the number of remaining eggs, the test is widely used to assess a woman’s ovarian reserve (egg count).

This diagnostic tool is valuable in fertility planning, helping to predict responses to IVF treatments and evaluate conditions like Polycystic Ovary Syndrome (PCOS). Additionally, it can help estimate the onset of menopause or investigate early ovarian insufficiency.
