“What is the main cause of PCOS?”

There isn’t exactly a main cause, and there were different presentations of polycystic ovary syndrome. The hallmark feature is ovarian dysfunction, often elevated levels of androgen hormones like testosterone, and the absence of other hormonal disorders that can present with similar symptoms. In many patients there is a genetic component, and others it may be related to weight gain that they have struggled with during their life. The elevated weight can cause elevated insulin levels which contributes to a lot of the problem.

If you suspect you have PCOS, it’s important to consult with your provider to understand the diagnostic work up and then health implications if you do have the condition.
