title: Amenorrhea following the use of oral contraceptives.
abstract: Clinical aspects and the incidence of the various underlying etiologic factors were studied in 86 patients with post-oral contraceptive amenorrhea. Patients were divided into two groups according to the presence or absence of detectable galactorrhea. Group I was composed of 55 amenorrheic patients without detectable galactorrhea and group II included 31 patients with amenorrhea associated with galactorrhea. Both groups were comparable for age, gravidity, duration of intake of oral contraceptives, and duration of amenorrhea. The incidence of previous oligomenorrhea and late menarche was high in both groups. The most striking difference between the two groups was in the incidence of pituitary prolactin-secreting tumor--32% among patients with galactorrhea and less than 2% among patients without galactorrhea. Identification of galactorrhea and accurate diagnosis of its causes are mandatory for successful management of postpill amenorrhea.
