AMH is a test commonly used to assess ovarian function, not to detect pregnancy.AMH is short for Anti-mullerian Hormone, a glycoprotein hormone secreted by the granulosa cells of the pre-sinus follicle and the sinus follicle. In layman’s terms, it is secreted by naïve follicles in the ovaries that are not yet developed and will be developed later. Therefore, you can check the level of this hormone in your body to indirectly know how many eggs are waiting to be developed in the ovaries. The level of this hormone is very low in childhood, gradually increases as sexual development matures, reaches a peak at the age of 20-25, and then gradually decreases with age until it reaches an undetectable level after menopause. Factors such as smoking, obesity, and vitamin D levels in the body can cause a decrease in this hormone. So in layman’s terms, this hormone is a test of egg reserve function in the ovaries and has nothing to do with pregnancy, the hormone that detects pregnancy is called HCG for short.
