Polycystic ovarian syndrome (PCOS) affects between five and ten percent of women. This common endocrine disorder can cause disruption in ovulatory and menstrual cycles, as well as an excess production of male type hormones, all of which can cause infertility. The cause of PCOS is likely a combination of genetic and environmental factors. There is a twenty to forty percent incidence of PCOS in women where either a mother or sister has also been diagnosed with the disorder.
