Treatment strategies for infertile women with polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is a common reproductive disorder that can be diagnosed when two of the following three criteria are present: menstrual irregularity, hyperandrogenism and polycystic ovaries. Factors such as the individual's body weight influence the severity of the phenotype and risk of metabolic comorbidities. While anovulatory infertility is a common issue among lean and obese reproductive-aged women with PCOS, obesity is associated with resistance to oral ovulation induction agents, lower pregnancy rates and a higher risk of pregnancy complications. Lifestyle modification is recommended as first line therapy among obese women with PCOS in order to optimize their outcomes. Among lean and obese women with PCOS, ovulation induction can be achieved with aromatase inhibitors, selective estrogen receptor modulators, insulin sensitizing agents, gonadotropins and ovarian drilling with varying rates of ovulation, live birth and multiple gestations. Assisted reproductive technologies are reserved for women who do not conceive despite restoration of ovulation or couples with additional factors contributing to their infertility. This review will outline treatment strategies for achieving a healthy pregnancy among lean and obese women with PCOS and infertility.
