The Anti-Mullerian hormone level is a blood test that evaluates how many eggs remain in your ovary. This is also known as "ovarian reserve." It does not tell us anything about the quality of your eggs. The quality of your eggs will mainly depend on your age and cannot be evaluated unless the eggs are taken outside of your body, and fertilization attempts are made.Every woman experiences a natural decline in AMH over time. Therefore, your levels need to be interpreted in comparison to your age group. The reference intervals on your laboratory results are usually vast and might not be useful in putting your egg reserve into perspective.At the time of menopause, the AMH levels become undetectable. The AMH is a relatively novel marker of measuring ovarian reserve, introduced into clinical practice somewhere around 2005. Previously, it was used in research only, mainly during embryonic development, since it is highly essential for male and female genital development. It is also known as MIS (Mullerian Inhibiting Substance). While males also produce AMH in the testicle, it has no clinical relevance for male patients.
