The anti-müllerian hormone (AMH) level in the blood is measured in this test. Both males and females produce AMH in their reproductive tissues. The role of AMH and whether or not levels are normal depends on age and gender.
AMH performs a crucial part in the development of a baby’s sex organs while he or she is still in the womb. A baby’s reproductive organs begin to mature during the first weeks of pregnancy. The baby will be born with the genes to be either a male or a female (XY genes) (XX genes).
If the baby inherits male (XY) Genetic material, high levels of AMH, as well as other male hormones, are produced. This inhibits the development of female organs while encouraging the growth of masculine organs. Organs of both sexes may form if there isn’t enough AMH to inhibit the development of female organs. When this happens, a baby’s genitals may be difficult to distinguish between male and female. The term for this is “ambiguous genitalia”. Intersex is another term for this situation.
Small levels of AMH are produced if the unborn baby possesses female (XX) genes. Female reproductive organs can develop as a result of this. Females after puberty have a different role for AMH. The ovaries (glands that produce egg cells) start producing AMH about this period. The higher the level of AMH, the more egg cells there are.
AMH levels in women can reveal information about fertility and the ability to conceive. The test could potentially be used to diagnose menstruation abnormalities or keep track of the health of women who have specific types of ovarian cancer. Ovarian cancer is a cancerous development of cells in the ovaries. The cells reproduce rapidly and have the ability to penetrate and kill healthy bodily tissue.
An AMH test is commonly used to determine a woman’s ability to create fertile eggs for pregnancy. During her childbearing years, a woman’s ovaries can produce hundreds of eggs. As a woman gets older, her number decreases. The amount of AMH in a woman’s blood can indicate how many potential egg cells she still has.
Ovarian reserve is the term for this. A woman with a high ovarian reserve may have a better probability of becoming pregnant. She may also be able to put off attempting to conceive for months or even years. If a woman’s ovarian reserve is low, she may have difficulty getting pregnant and should try to have a baby as soon as possible.
AMH testing is useful for the following reasons, including:
- It can assist in predicting the start of menopause, the period in a woman’s life when her monthly periods stop and she is no longer able to conceive. When a woman reaches the age of 50, it typically begins.
- Learn why the individual is experiencing early menopause.
- Aids in the diagnosis of amenorrhea, or the absence of menstruation. It’s more likely in girls under the age of 15 who haven’t started menstruating
and women who have skipped many cycles.
- Assists with the identification of polycystic ovarian syndrome (PCOS), a hormonal disorder that is a common cause of infertility in women.
- Infants whose genitals aren’t marked as male or female should have their genitals examined.
Specific types of ovarian cancer in women should be properly watched.
AMH is important for the development of a baby’s sex organs while in the womb. Male newborns have higher levels of AMH because it suppresses the development of female reproductive organs. A tiny amount of AMH is required for the development of female infants.
AMH is produced by cells inside the follicles of the ovaries in women. Follicles are small fluid-filled sacs that hold and release eggs in the ovary.
The number of eggs you have or your ovarian reserve is related to your AMH levels:
- More eggs and a larger ovarian reserve are associated with greater
- Fewer eggs and a lesser ovarian reserve are associated with
decreased AMH levels.
Average AMH levels by age:
- AMH values of more than 1.0 Nanograms per millilitre are considered normal.
- A concentration of fewer than 1.0 Nanograms per millilitre may be cause for
- Polycystic Ovarian Syndrome (PCOS) is a hormonal condition that affects many women of reproductive age. Women with PCOS may have irregular or extended menstrual cycles, as well as high levels of the male hormone androgen. The ovaries may produce a large number of tiny collections of fluid (follicles) and fail to release eggs on a regular basis. PCOS could be the cause if AMH levels are higher than 3.0 Nanograms per milliliter.
- AMH levels that are undetectable may indicate poor reproductive health.
