Polycystic Ovarian Syndrome has many causes, one such cause of PCOS can be Hormonal Imbalance

Polycystic ovaries develop when the ovaries are stimulated to produce excessive amounts of male hormones causing multiple ovarian cysts. The cysts are immature follicles that may appear as a chain of pearls but have stopped developing. Not all women with PCOS have trouble conceiving – but a course of treatment is required to achieve a successful pregnancy.
