Antimüllerian hormone, a member of the transforming growth factor beta superfamily, is a glycoprotein secreted by immature Sertoli cells of the testis and granulosa cells of the antral follicles and small sinus follicles of the ovary, and is a timer reflecting ovarian reserve function. What are the main uses of anti-Müllerian hormone? First, to assess the reserve function of the ovary. Secondly, to predict premature ovarian failure. Third, to predict the age of onset of menopause. Fourth, auxiliary diagnosis of polycystic ovary syndrome. Fifth, prediction of ovarian responsiveness in assisted reproductive technology. Sixth, auxiliary diagnosis of abnormal gender development in children. Seventh, assessment of toxic damage to gonads by radiotherapy. Eighth, diagnosis and detection of granulosa cell tumors of the ovary. If a woman has problems with her ovaries, it will easily affect her fertility. In the face of fertility and physical health problems, hormone replacement therapy, sperm and egg transplantation, cryopreservation techniques, and psychotherapy can be used to help women be able to conceive again and become mothers. A better approach is that women should know how to regulate their body, work and rest regularly and protect their ovaries.
