Where does Anti-Müllerian hormone (AMH) stand in fertility?

Anti-Mullerian Hormone or AMH is a fertility hormone produced in the body of women. It is produced by tiny preantral follicles present in the ovaries. As it is known, the quantity of eggs in the ovarian reserve depletes with time. And, with the depletion in the quantity of eggs, AMH levels deplete too.

Furthermore, AMH impacts ovarian follicle growth directly. This happens because the dropping levels of AMH affect the sensitivity of the ovaries to ovarian stimulating hormones.

Thus also makes AMH a strong and dependable source of information for the state of the fertility of a woman. In addition to this, AMH remains predominantly constant all through one’s menstrual cycle. Hence, it is a better choice for mapping and analyzing the condition of one’s fertility.

Test tube baby treatment experts and infertility treatment doctors enlist the following reasons why AMH is a more reliable marker of fertility:

  • The levels of AMH are consistent all through the menstrual cycle. A standard procedure of analysis can be followed in all kinds of clinical laboratories.
  • No specific time is required to measure AMH levels.  The doctor does not have to wait for the menstrual cycle to end or begin.
  • Other markers of measuring or analyzing the fertility of a woman such as Follicle Stimulating Hormone or FSH and Antral follicle count or AFC are much less reliable than AMH. FSH, on one hand, the FSH hormone loses its consistency at different stages of the menstrual cycle while on the other hand, AFC levels may predict ovarian response to fertility treatments with commendable accuracy, yet, they depend on the stages of menstruation too extensively. Additionally, there are high chances of misinterpreting its results.

So how can AMH levels be tested?
AMH levels can be tested or analyzed through a blood test. These tests help determine numerous things some of which include estimating if a women could undergo early menopause hence preparing her for the high chances of her losing her fertility earlier than average.

Below are mentioned the values obtained in an AMH test and their meaning:
