Patients with polycystic ovary syndrome (PCOS) who do not have menstruation due to hormone level disorders in the body can be treated through lifestyle modification, medication and surgery. 1. Lifestyle modification: controlling diet and increasing exercise to reduce body weight and waistline can increase insulin sensitivity and lower insulin and testosterone levels, thus restoring ovulation and fertility, i.e. menstruation. 2. Medication: oral contraceptive pills to adjust the menstrual cycle, cyproterone, spironolactone and other drugs to reduce blood androgen levels, metformin to improve insulin resistance, clomiphene can promote ovulation. The use of specific drugs need to be under the guidance of the doctor. 3. Surgical treatment: such as laparoscopic ovarian perforation, surgical treatment is generally only applicable to the second-line treatment of clomiphene-resistant patients. Patients with polycystic ovary syndrome who want to have menstruation can go to the hospital and be treated under the guidance of a specialist.
