Antimullerian Hormone (AMH) and Ovarian Reserve

By CNY Fertility Updated on

The field of fertility studies is constantly evolving and advancing.  In response to current research, we are happy to make Antimüllerian Hormone (AMH) testing available to our clients.  This hormone has been found to indicate ovarian reserve (the amount of follicles remaining) and predict challenges such as hyperstimulation and poor stimulation response.  This hormone does not greatly fluctuate during a cycle, and so it can be tested at any point.  The test required is a simple blood test, resulting in a number indicating the amount of hormone in the body.  Researchers have found a few interesting relationships between AMH levels and fertility:

  • When the level of AMH in the system decreases, so does ovarian reserve and fertility.
  • Age, obesity, administration of chemotherapy or radiation, and surgical of one or both of the ovaries, also decreases the level of AMH in the body.
  • Polycystic Ovarian Syndrome (PCOS) increases the level of AMH in the body.
  • Birth control pills, pregnancy, and day of cycle do not influence AMH.

After your simple blood test, you will receive a number indicating the amount of AMH within your body.  A level less than 0.2-0.5 nd/mL is commonly associated with an increased chance of cancelled IVF cycle, poor response, and fewer eggs retrieved from the ovaries.  Levels greater than 2.5 ng/mL are associated with greater egg production, and a better potential for fertility.  If your AMH is high, greater than 3.6 ng/mL, you may be at a higher risk for ovarian hyperstimulation.
If you are interested in testing your AMH level, please feel free to ask one of our nurses at your next visit.  We would be happy to further explain this test, its benefits, and limitations.
