The patient with polycystic ovary syndrome

Introduction Polycystic ovary syndrome (PCOS) is the commonest hormone disorder of young women and, therefore, presents frequently in couples seeking to become pregnant either as a contributory factor to infertility problems or as an incidental finding amongst other causes.1,2 PCOS has many consequences for pregnancy, whether natural or assisted and it is essential that the diagnosis is made before a woman seeks to become pregnant. Even if the condition is not present as the syndrome, it is important to determine the ovarian morphology on ultrasound prior to stimulation with gonadotrophins.
