Experimental Factor Ontology entry EFO_0004769 (anti-Mullerian hormone measurement) can be described as follows. Is a quantification of anti_Mullerian hormone, and is used as a biomarker of ovarian reserve. The AMH is  produced by the granulosa cells of the early developing antral follicles.  These  are the immature eggs that wake up from their dormant state and develop into mature eggs.  As the number of oocytes decline, the number of  small antral follicles decline in number and  the serum Anti-Mullerian hormone level falls. Also known as: anti-Mullerian hormone level, anti-Mullerian hormone levels.
