Polycystic ovary syndrome, a closely related ovarian disease to female infertility, is now very common. The pathogenesis is not well understood. The pathology of the ovary is explained by the thickening and sclerosis of the ovarian cortex causing abnormal follicular development and ovulation. Most patients see multiple follicles developing each menstrual cycle, but none of them can reach maturity or ovulate. A typical patient with polycystic ovary syndrome presents with the following symptoms: 1) obesity and weight gain; 2) hirsutism: long, coarse and black body hair and beard; 3) rough skin: coarse pores on the cheeks; 4) scanty or amenorrheic menstruation: prolonged cycles of 40 days, 2 months, 4 months, or even longer; 5) sex hormone tests: elevated follicle stimulating hormone (FSH), elevated testosterone (T), and elevated lactogen; 6) ultrasound Ultrasound: Bilateral ovarian polycystic changes (several or tens of small follicles), uterine volume can be reduced or small, thinning of the endometrium. Treatment of polycystic ovary syndrome: 1. Pharmacological ovulation promotion: short-acting contraceptives (Dain 35, etc.), clomiphene, chorionic gonadotropin (hCG), menopausal human gonadotropin (hMG). The first step: short-acting contraceptives, used for 3 months, without ovulation for 3 months after stopping the pill, is considered ineffective. Ovulation and pregnancy are considered effective. Step 2: Clomiphene for 3 months, with ovulation during the period of use is considered effective, while anovulation without pregnancy is considered ineffective. Step 3: Combined program (super ovulation), using hMG, hCG, FSH and other ovulatory drugs for 3 months, ovulation and pregnancy is considered effective, no ovulation is considered ineffective. 2.Surgical ovulation promotion: 3-6 months of medication, if not effective, surgical treatment can be performed. The preferred surgical method is laparoscopic ovarian perforation. The purpose of this surgery is to remove the thickened cortex on the ovarian surface to achieve ovulation. Most patients resume normal ovulation after surgery. If pregnancy is needed as early as possible, postoperative ovulation medication can be added.
