Women are born with their lifetime supply of eggs and over time, these eggs gradually decrease in quantity. The good news is that a simple blood test gives an indication of the egg reserve. It’s called an AMH (Anti-Mullerian Hormone) test. AMH is a hormone secreted by cells in developing egg follicles. Research performed at Repromed has proven that AMH testing gives the best indication of egg supply.
As women age, their ovarian reserve, and subsequently their fertility, gradually declines. However, for some women their fertility may decline at a faster rate than expected, even though they experience normal menstrual cycles.
The AMH test can identify women who may lose their fertility earlier that average and may help in deciding whether to start a family sooner or later.
In 75% of women, the AMH levels can also help predict how a woman will respond during IVF treatment. Your fertility doctor uses your AMH level to prescribe an appropriate dose of drugs to stimulate the ovaries to obtain a sufficient amount of eggs or to minimize the risk of hyper-stimulation.
AMH doesn’t change during the cycle so this blood test can be taken at any time, including while using oral contraception. Some patients may find that the contraceptive pill artificially lowers the AMH level and so the test may be repeated 8 weeks after stopping the pill. GP’s can organize an AMH test, or Repromed can organise this.

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.
