What is polycystic ovary syndrome? Polycystic ovary syndrome is a complex disease with a wide range of clinical manifestations caused by defects in reproductive and metabolic functions. The most prominent manifestations are prolonged menstrual cycles, enlarged ovaries with polycystic-like changes, and hyperandrogenic symptoms. Patients with polycystic ovary syndrome have the following common features: 1. Irregular menstrual cycle. The most common ones are delayed menstruation and amenorrhea, and after the medication is adjusted to normal, then after some time, the delayed menstruation and amenorrhea are repeated. Because polycystic ovary syndrome is not a disease that can be cured, short term treatment can improve your menstrual cycle or help you to resume ovulation, but it will not eliminate the disease and prevent future attacks. 2. Ultrasound indicates that the ovaries are enlarged and there are more than 12 follicles larger than 5 mm in the ovaries. 3. Obesity. About 44% of the patients are obese, mainly because of the metabolic disorder, which leads to the reduction of sugar and lipid consumption, so diet control and physical exercise, is very important. 4, hairy 5, easy to miscarry
