This paper reports a review of 55 cases of polycystic ovary syndrome by general practice registrars in the Waikato region of New Zealand. In addition to demographic data, presenting symptoms, diagnostic tests, associated conditions and treatment post-diagnosis are discussed. The majority of cases (76%) were first diagnosed by the general practitioner. The review suggests there may be a need for better recording of key diagnostic criteria and that ultrasound is being widely used as a diagnostic test despite local guidelines discouraging its use if other appropriate diagnostic criteria are met.
