Services » Fertility Investigations » AMH Levels

The anti-mullerian hormone is produced by the very smallest follicles (which house the developing eggs). A low AMH indicates there may be fewer follicles developing. The number of small follicles developing is thought to be reflective of the total number of eggs remaining or ‘pool’ which has given rise to the association of a low AMH with a diminished ovarian reserve. However, the immune system can inhibit the recruitment of follicles in the ovary, leading to a low AMH even though there are plenty of eggs left.
