The ovarian function can be judged by clinical manifestations, the six female sex hormones, Mullerian duct inhibitor test, vaginal ultrasound test, etc. Usually everything is normal to indicate good ovarian function. The presence of menopausal symptoms, a significant decrease in Mullerian duct inhibitor, and follicle stimulating hormone over 40 U/L indicate a declining trend of ovarian function. 1. Clinical manifestations: The female menstrual cycle, menstrual volume, and female skin color can be used to make a comprehensive judgment. Decreased menstrual flow or even menopause, dull and yellow skin, especially menopausal symptoms such as irritability, insomnia, sweating, hot flashes, etc., indicate a decline in ovarian function. When ovarian function decreases, fertility decreases significantly; 2. Six female sex hormones: Six sex hormones include estrogen, progesterone, androgens, follicle stimulating hormone, luteinizing hormone and pituitary lactogen, of which ovarian function is mainly judged by checking follicle stimulating hormone, more than 40 U/L indicates a decreasing trend of ovarian function; 3. Mullerian duct inhibitor test: Mullerian duct inhibitor appears 4. Vaginal ultrasound test: It can observe the development of the fallopian tubes and ovaries bilaterally, as well as the number of follicles to determine whether the ovarian function is perfect. In the presence of decreased ovarian function, estrogen and progestin replacement therapy is usually given. However, in cases where there is a primary cause of decreased ovarian function, such as hyperprolactinemia-induced decreased ovarian function, the cause should be treated.
