DEAR DOCTOR K: I was just diagnosed with polycystic ovary syndrome. My doctor said it explains why I haven't been able to get pregnant. What else can you tell me about this condition?
DEAR READER: Polycystic ovary syndrome (PCOS) is a group of symptoms that results from an imbalance of certain hormones in the female body. It is relatively common: About 7 to 8 percent of adult women in the United States have PCOS.
