Polycystic ovary syndrome: symptomatology, pathophysiology, and epidemiology.
Women with polycystic ovary syndrome seek health care for 3 major reasons: infertility, menstrual irregularity, and androgen excess. The infertility is associated with anovulation. The menstrual irregularity is typically chronic, beginning with menarche. Although amenorrhea may sometimes occur, the more common presentation is irregular bleeding characteristic of anovulation. Androgen excess may be manifested by varying degrees of hirsutism. Patients may also report acne. The rapid development of virilizing signs, such as deepening of the voice, increased muscle mass, and temporal balding, should prompt a search for a tumor and lead one away from a diagnosis of polycystic ovary syndrome. Typically treatment is directed at alleviating the symptoms: ovulation induction for infertility, oral contraceptives or a progestin for menstrual irregularity, and oral contraceptives or spironolactone for hirsutism. On the basis of recent epidemiologic data suggestive of increased cardiovascular risk among women with polycystic ovary syndrome, such treatment might be complemented by a long-term approach that addresses the underlying pathophysiology of insulin resistance.
