Anti-Müllerian Hormone (AMH) is a protein hormone produced by the ovaries in females and by the testes in males. In females, AMH plays a crucial role in the development of ovarian follicles, which are essential for fertility. It helps regulate the growth of these follicles and is often used as a marker for ovarian reserve, indicating the number of viable eggs a woman has. In males, AMH is important during fetal development, as it prevents the formation of female reproductive structures. Measuring AMH levels can provide insights into reproductive health for both genders, making it a valuable tool in fertility assessments and treatments.
