What indicates a low ovarian reserve in terms of AMH levels?

Anti-Müllerian hormone (AMH) is a crucial indicator of ovarian reserve, which reflects the remaining quantity of eggs in the ovaries. Low levels of AMH are associated with a diminished ovarian reserve, suggesting that the ovaries have fewer follicles and eggs available for ovulation. This is particularly important for assessing fertility potential.

As women age, AMH levels typically decrease, making low levels a reliable signal of reduced ovarian function. Physicians often use this information to help patients understand their fertility status and make informed decisions regarding family planning or fertility treatments. In contrast, high, normal, or variable AMH levels would not indicate a low ovarian reserve, as they suggest either an adequate or fluctuating number of follicles. Thus, low AMH levels serve as a clear marker for low ovarian reserve.
