Patients with polycystic ovary syndrome (PCOS) are not limited to ovulation induction; if metabolism improves and ovulation is not resumed after lifestyle improvement, ovulation induction therapy can be given. The impact of polycystic ovary syndrome on fertility is mainly manifested in the absence of ovulation or sparse ovulation, resulting in difficulties in conception. It is firstly recommended to reduce body weight and improve the symptoms related to hyperandrogenemia through “diet + exercise + cognitive behavioral” lifestyle intervention, so as to restore the function of ovulation, and those who have not yet resumed ovulation after the above efforts, can be treated with drug ovulation promotion. If ovulation is not restored after the above efforts, the patient can be treated with medication to promote ovulation. Patients with polycystic ovary syndrome should exclude their spouses’ infertility factors before ovulation induction therapy, and the commonly used drugs include letrozole and clomiphene, and the selection of drugs should be carried out under the guidance of reproductive medicine physicians, and if there is any discomfort during the medication period, timely hospital consultation should be made.
