Guide | Anti-Müllerian Hormone Levels: An Important Fertility Indicator
Anti-Müllerian hormone (AMH) is produced naturally in the body and plays an important role in fetal reproductive-organ development and lifelong reproductive health. AMH levels and functions vary by age and sex.
AMH Levels During Fetal Development
Early in pregnancy, fetal reproductive organs begin to develop. Male fetuses have much higher AMH levels than female fetuses, and the hormone helps prevent female reproductive organs from forming. If a male fetus does not produce enough AMH, ambiguous or both male and female reproductive structures may develop, a condition known as ambiguous genitalia or intersex development.
Female fetuses require only a small amount of AMH for reproductive-organ development. The hormone becomes more important after puberty because it is involved in egg development and reproductive function.
AMH and Fertility
Women concerned about fertility can ask a doctor about AMH testing. The test provides information about ovarian reserve and can help assess reproductive potential. It may also be used to monitor reproductive health and certain ovarian cancers.
Understanding the AMH Test
An AMH test measures the level of AMH in the blood and is often ordered for women having difficulty conceiving. The ovaries contain thousands of eggs over a woman's lifetime, and AMH levels are associated with the number remaining. AMH naturally declines with age, which may indicate fewer or no remaining eggs.
Health conditions can affect fertility even during the reproductive years. An AMH blood test helps a doctor understand reproductive potential, but additional laboratory testing is usually needed.
When Is AMH Testing Used?
A doctor may recommend AMH testing to estimate the timing of menopause, investigate early menopause (the average age is 51), or diagnose hormonal conditions such as polycystic ovary syndrome (PCOS). It can also help evaluate ambiguous genitalia in infants or monitor certain ovarian cancers.
Understanding AMH Test Results
A normal AMH level generally indicates a greater ovarian reserve. A high level may suggest PCOS and may lead to treatment or lifestyle changes to manage symptoms. A low level indicates fewer eggs available for fertilization and may be associated with difficulty conceiving, although low levels are normal before puberty and after menopause.
Factors Affecting AMH Testing
Several external factors may affect AMH results. Before recommending testing, a doctor usually reviews family history and lifestyle, including a family history or previous diagnosis of PCOS, ovarian surgery, chemotherapy, oral contraceptive use, obesity, genetic variants that increase breast or ovarian cancer risk, and vitamin D deficiency.
