Probability that an adolescent with symptomatic anovulatory symptoms will have ongoing menstrual abnormality

Probability that an adolescent with symptomatic anovulatory symptoms will have ongoing menstrual abnormality. The "All symptomatic cases" curve represents the data of Southam, et al (Southam and Richart 1966). "Hyperandrogenic" and "Non-hyperandrogenic" curves are hypothetical, based on data discussed in the text. Hyperandrogenic cases are predominantly a mix of physiologic anovulation and PCOS, with PCOS persisting. Non-hyperandrogenic cases are a mix of physiologic anovulation and hypogonadal cases (ranging from primary hypogonadism through hypothalamic amenorrhea to hypogonadotropic hypogonadism), with hypogonadal cases persisting.
