Anovulatory dysfunction is common in adolescent women and also in menopausal women. It is mainly characterized by the absence of ovulation, increased menstrual flow, and prolonged menstruation. In most cases, the vaginal bleeding will be significantly reduced after the use of the drug. Functional uterine bleeding during menopause can be treated clinically with progesterone, which will also significantly reduce vaginal bleeding about 24-48 hours after administration. In this case, the key is to give a clinical diagnosis to exclude organic lesions, which requires ultrasound, routine blood tests, gynecological examination, and sex hormone tests.
