Polycystic Ovarian Syndrome(PCOS) refers to women who present with a variety of complaints including irregular menses; long menstrual cycles; acne; excessive body hair; difficulty keeping weight down and infertility. Once the diagnosis is confirmed - based on a history, some hormonal blood tests and an ultrasound scan of the pelvis, further management is tailored to meet the patient's priorities eg ovulation stimulation if infertility is the problem; Dianette if acne and excess hair are the dominant problems; metformin with dietary and exercise advice if weight control is the main issue.
