AMH is an anti-müllerian hormone, which can detect the ovarian reserve capacity, and the normal value ranges from 2~6.8ng/ml. AMH value of only 0.01ng/ml may be a normal menopausal phenomenon, or it may be caused by premature failure of ovarian function, which is more serious. 1. Menopause: with age, ovarian function will gradually decrease, so AMH value will decrease. So when the AMH value decreases to 0.01ng/ml, it is likely to be a normal menopause, so there is no need to worry too much. 2. Premature Ovarian Failure: When there is premature ovarian failure, the AMH value will also decrease. When the AMH value drops to 0.01ng/ml, it means that the situation is more serious and may affect the ovarian function, which in turn leads to infertility. With an AMH value of only 0.01ng/ml, it is recommended to go to the hospital in time to find out the cause. If it is premature ovarian failure, it should be treated as early as possible to avoid affecting fertility.
