title: Ovulation recovery after hormonal contraception.
abstract: In an attempt to study the ovulation recovery after hormonal contraception, 20 patients who were on B. C. P. (birth control pills) during 12--36 months, were switched to I. U. D. contraception, and the ovarian changes occurred were assessed by laparoscopy and laparoscopic ovarian biopsy. Fresh corpus leuteum was found in 12 cases (60%), some follicular activity in 4 cases (20%) and no signs of activity in 4 cases (20%). Our results suggest that neither the length of hormonal contraception nor the patient's age have any particular influence upon the return of ovulation.
