Irregular periods. This is the most common characteristic. Examples include menstrual intervals longer than 35 days; fewer than eight menstrual cycles a year; failure to menstruate for four months or longer; and prolonged periods that may be scant or heavy.
Excess androgen. Elevated levels of male hormones (androgens) may result in physical signs, such as excess facial and body hair (hirsutism), adult acne or severe adolescent acne, and male-pattern baldness (androgenic alopecia).
Polycystic ovaries. Polycystic ovaries become enlarged and contain numerous small fluid-filled sacs which surround the eggs.
