Outcome in patients with post-pill amenorrhoea.

Ninety-six patients who developed amenorrhoea following the use of oral contraceptives were studied in two groups; one with a history of regular periods and the other with irregular periods prior to the use of oral contraceptives. Pregnancy rates were similar in patients with and without a previous history of menstrual dysfunction. Thirty-nine of 47 patients who desired pregnancy and in whom there was no definable factor inhibiting pregnancy, succeeded in conceiving.
