What is AMH used for?

AMH is most useful during IVF for predicting how the ovary is likely to respond to hormonal treatment with FSH. (For more information on IVF and FSH see my section on IVF/ICSI Treatment). This in turn will help to predict the numbers of eggs that may be retrieved at egg pick-up as well as give guidance on the dose of FSH to be used. In general, women with higher AMH levels require lower doses of FSH and will produce more eggs compared with women with very low AMH levels.

AMH has also been suggested to be able to predict fertility potential. However, AMH does not predict fertility potential, see section below on “Does AMH predict whether I can fall pregnant naturally?”

Another proposed use for AMH is to predict the time of the menopause. Again, studies do not clearly show that AMH is useful for this purpose. See my section on Menopause for more information.

AMH has also been linked with risk of miscarriage. Some studies suggest that very low AMH levels may be associated with a higher risk of miscarriage. The largest study on this issue did not find that AMH was linked with miscarriage. This year, the American College of Obstetricians & Gynaecologists concluded that “Routine antimüllerian hormone testing for prediction of pregnancy loss is not recommended”.
