What is AMH?
AMH (anti-Müllerian hormone) is secreted by small antral follicles in the ovary. It has received a lot of attention in recent years as it is thought to be a good indicator of a women’s levels of ovarian reserve, or, in other words, how likely she is to be able to conceive.
When tested, it has been suggested that higher levels of AMH are better, and are associated with greater chance of natural conception, as well as success in assisted conception such as IVF cycles.
Is it controversial?
Some scientists have claimed that once AMH is low, there is no turning back. In effect, you are approaching menopause, and there is little chance that you will conceive. However, many disagree with this view, and see clinically that AMH can increase as well as decrease.
AMH may, in fact, just be an indicator of the number of follicles that are currently developing in the ovaries. It takes around 120 days for primordial follicle to complete their life-cycle from formation to potentially releasing an egg. Processes and treatments that are able to increase the number of primordial follicles that are initiated to grow, may be able to increase the levels of AMH over a 3-4 month period.
What is less controversial is that low AMH in a cycle is a good indicator that success with IVF is less likely.
