What is AMH and why does IVF depend on it?

AMH, or anti-Müllerian hormone, is more interesting than its name suggests. It’s a useful protein associated with the reproductive system – and an AMH test can help IVF patients evaluate their chances of success.

AMH is secreted by cells in a woman’s growing follicles. (Men produce a little AMH too.) Testing plasma levels of AMH before IVF is a useful indicator of ovarian reserve and potential response to IVF drugs. If AMH levels are within the normal range, your ovaries may react better to stimulating medication. Overly low or high levels aren’t so good.

So your AMH test lets you and your doctor make an informed choice on whether or not to go ahead. A reasonably high, rather than a reasonably low, AMH score is generally best. More follicles usually lead to more collected eggs after IVF stimulation. If there are more eggs to fertilise, there may be a better selection of embryos to transfer
