AMH level, testing for ovarian reserve

AMH (antimullerian hormone, mullerian inhibiting hormone) level is blood test that is used to check ovarian reserve. This hormone was first noted to be involved in process of organ development but is important for fertility because it is produced by the cells surrounding the eggs early on. The amount of AMH in the bloodstream gives us an indication of the number of eggs available to respond to fertility drugs and that potentially may result in a pregnancy. Ovarian reserve is a way a of measuring the quantity (number) and to a lesser extent, the quality of your eggs. 

Having a low AMH level ( <1.0) suggests that you may not respond as well to fertility drugs and may have a lower chance for success with IVF. A high level ( > 3.0) suggests that you have a large number of eggs or even a condition called polycystic ovarian syndrome (PCOS).  A very low AMH level while a cause for concern is not a cause for panic. We have seen women with barely detectable AMH levels conceive and deliver.


AMH is one of several tests for ovarian reserve including day 3 FSH and estradiol levels, antral follicle count (counting the number of eggs on ultrasound) and Inhibin B levels which is less commonly done.
