Egg production is a lifelong process for women, and as they age, the amount and quality of their eggs steadily decline. An egg is typically released by a woman once a month. If a woman is not pregnant during that month, the eggs that are not chosen to ovulate will disintegrate and the cycle will start over. Follicles in developing eggs release a hormone called anti-Mullerian hormone (AMH). An accurate measure of a woman’s ovarian reserve may usually be found in her blood level of AMH.
What is AMH Level
In order to determine a woman’s ovarian reserve or egg count, OBGYNs and infertility specialists often employ a laboratory test known as anti-mullerian hormone (AMH). The tiny follicles in a woman’s ovaries create this hormone. AMH is one way to measure the quantity of oocytes. You may find out how many eggs you still have and whether your ovaries are aging too rapidly with an AMH test. It can show that your window of opportunity to become pregnant is shorter. How successfully you react to injectable fertility medications that stimulate your ovaries to develop numerous eggs in preparation for in vitro fertilization (IVF) may also be shown by an AMH test.
Which AMH values are typical for each age group?
Your age affects your AMH level. Adolescence is when women’s AMH levels begin to rise, and they peak at age 25. AMH levels then eventually drop after that. AMH levels are measured by providers in nanograms per milliliter, or ng/mL.
It is normal to experience a decrease in ovarian reserve in your 30s, 40s, and 50s as AMH levels typically decline as you age. Below are the AMH levels for different ages.
AGE AMH levels
20–25 years 4.23 ng/mL
26–30 years 3.48 ng/mL
31–35 years 2.43 ng/mL
36–40 years 1.28 ng/mL
40–44 years 0.52 ng/mL
