What Is PCOS?
2. Causes and Risk Factors
Unfortunately, there is no definitive answer as to what causes PCOS. Any woman of childbearing age can develop PCOS at any time. The typical age range of those who develop the condition is 15 to 44.
PCOS may have a hereditary component since certain genes have been linked to the syndrome. Moreover, some studies indicate that PCOS has an autosomal dominant mode of inheritance in many families. In short, this means that a person is more likely to develop PCOS if a first-degree relative has it (mother or sister). Finally, obesity and insulin resistance may also increase the risk of developing PCOS.
