AMH is one of the most widely used biomarkers for assessing ovarian reserve because it provides insight into the number of remaining eggs within the ovaries. Unlike many reproductive hormones, AMH remains relatively stable throughout the menstrual cycle, making it a reliable marker that can be measured at almost any time. While AMH does not directly measure fertility or predict the ability to conceive naturally, it offers valuable information about reproductive aging and ovarian function.

AMH levels naturally decline with age, often years before noticeable changes in menstrual cycles occur. Monitoring AMH can help women better understand their reproductive timeline, identify trends in ovarian health, and make more informed decisions about future family planning. It also provides useful context when evaluating overall hormone health and age-related changes.
