The amh value is clinically known as the anti-Mullerian hormone and ranges from 2.0 to 6.8 ng/ml. amh values also vary according to age, with older organisms having relatively low amh values. Because the amh value is used to indicate the function of the female ovaries, when the amh value is low it indicates poor ovarian function or even the possibility of premature ovarian failure. In menopausal women, the amh value will be lower than 2.0ng/ml. In women of childbearing age, if the amh value is below the normal range, it means that the ovarian reserve function is poor and the chance of conception is generally low. Once the amh value is higher than 6.8 ng/ml, it indicates that the woman is suffering from polycystic ovary syndrome and the possibility of granulosa cell tumor is higher, so it is recommended to go to the hospital for ultrasound examination in time.
