Amh (anti-müllerian Hormone)

The AMH test measures the level of Anti-Mullerian Hormone in the blood.

Other names: AMH Test

 Anti-Mullerian Hormone is a hormone produced by ovaries in females and by the testicles in males. The amount of AMH differs according to age and gender of a person.

In early years of development of a baby boy, the testicles produce AMH, thereby promoting the development of male reproductive organs. The levels of AMH remain high in boys until they hit puberty.

In girls the levels remain low until puberty thus allowing for the female reproductive organs to develop and post puberty, the ovaries produce AMH and the levels remain high during the child bearing years and taper off to undetectable levels post menopause.

In women, the AMH levels regulate the LH and FSH levels during the process of ovulation. Thus, the amount of AMH present in the blood is an indication of follicular growth.

Since AMH levels is a reflection of the follicular growth, it gives an indication of a woman’s ovarian reserve and therefore is an indication of fertility or the likelihood of conceiving. The test is also one of the many tests ordered to diagnose PCOS. PCOS is a condition where the levels of AMH is elevated due to excess follicles producing abnormally high levels of AMH. AMH can also predict the onset of menopause.

AMH test in women:

1. The test is used in women to evaluate infertility, determine ovarian reserve and to estimate the time that is available for conceiving. Basically AMH is used as an ovarian function test.
2. AMH is sometimes also ordered for women who are undergoing in-vitro fertilization. The amount of AMH will help evaluate the response to stimulation.
3. AMH can also be used to determine if menopause has already set
4. To diagnose PCOS and is used along with the clinical findings and other test results
5. In certain ovarian cancers, AMH levels are found to be high – in such cases, the AMH test is also used as a tumor marker test.

AMH test in infants is used along with other tests in case of ambiguous genitalia.

Response to hormonal stimulation - ng/ml

Negligible < 0.2

Reduced 0.2 - 1.0

Normal 1.0 - 7.0

High (OHSS Risk) > 7

Interpretation

Your doctor will help interpret the report basis your clinical findings. High levels of AMH indicate PCOS. Low levels of AMH relate to poor ovarian reserve. When AMH is found to be high in certain types of ovarian cancer, levels are monitored to estimate disease progression and treatment effectiveness.
