Anti-Müllerian hormone (AMH) is produced in the granulosa cells. It is mainly produced by the early stages of the follicles (egg follicles) that have not yet been consumed. Therefore, a determination of this hormone is suitable for assessing the "ovarian reserve". The hormone can be determined independently of the day of the cycle.

The number of egg cells is already determined at birth and decreases in the course of life. The level of anti-Müllerian hormone corresponds to the amount of follicles still present and therefore also decreases with the years.

Limit value: If the AMH value falls below 1 ng/ml (corresponds to 7pmol/l), one speaks of a reduced oocyte reserve or restricted ovarian reserve.
