[Troglitazone for treatment of polycystic ovary syndrome]

Polycystic ovary syndrome(PCOS) is characterized by clinical symptoms such as menstrual dysfunction, unovulatory infertility, masculinization, obesity, polycystic ovary by ultrasound, and endocrine abnormalities such as hyperandrogenism, and elevated LH to FSH ratio. Recent reports suggest that insulin resistance plays an important role in the pathogenesis of PCOS, and several insulin sensitizing agents have been used for the treatment of PCOS. Troglitazone, one of the thiazolidinediones, improves not only insulin sensitivity but also hyperandrogenism and ovulatory function. Troglitazone appears to be useful in treating women with PCOS. Further investigations are needed to assess the effectiveness and safety.
