Another complication can be polycystic ovary syndrome (PCOS).This is caused by an imbalance in male and female hormones in the woman's body, whereby a woman's body produces more of the male hormone testosterone than usual. Due to this imbalance, the ovaries do not form follicles, and this can block the release of eggs (ovulation). A typical manifestation of this syndrome is the accumulation of follicles in the form of small cysts in the ovarian cortex.PCOS is often associated with obesity and diabetes.
