One of the leading causes of infertility is Polycystic Ovary Syndrome, a hormonal condition where women don't ovulate.

It also causes a host of difficult symptoms, including pelvic pain, thinning hair and weight gain.  It's also very difficult to treat.

Now University of Colorado researchers, joining peers in six other states, have found a drug they say is more effective than the one now on the market. Their findings appear in a recent edition of the New England Journal of Medicine.  

Dr. Ruben Alvero, a professor of obstetrics and gynecology at the CU School of Medicine, speaks with CPR's "Colorado Matters." Alvero was one of the lead authors of the study.
