Female Fertility Test (AMH)

Anti-mullerian hormone (AMH) is a female fertility marker that gives an estimate of the remaining egg supply, or “ovarian reserve”. AMH levels can be tested on any day of the cycle by a simple blood test.

What is AMH ?

Anti-Mullerian Hormone (AMH) is produced directly by granulosa cells in the ovarian follicles, therefore, AMH levels correlate with the number of antral follicles in the ovaries . It has been documented that women with lower AMH have lower antral follicular counts and produce a lower number of oocytes compared with women with higher levels.

AMH can be used for:

  • Evaluating fertility potential and ovarian response in IVF - AMH levels correlate with the number of early antral follicles. This makes it useful for predicting ovarian response in an IVF cycle. Women with low AMH levels are more likely to be poor ovarian responders.
  • Measuring diminished ovarian reserve - this is signalled by reduced AMH levels

Graph of Normal AMH Range

The graph below shows the change in normal AMH range with age.  The breadth and value of this range reduces with age, which reflects the diminishing ovarian reserve.
