Post-pill ovulation resumption

ABSTRACT

The return of ovulation after discontinuation of oral contraceptives was studied in 247 pill users. Ovulation resumption was determined by studying the cervical mucus changes at mid cycle and first day endometrial biopsy. Ovulation was resumed in approximately 81 percent and 96 percent at second and fourth months respectively, after cessation of contraceptive pills. By 6 months, 99.5 percent of the pill users had ovulated. The pregnancy rate after 6 months of pill discontinuation was about 27.5 percent. The ovulation and pregnancy resumption, after pill discontinuation, was affected by the age, the duration of pill use. It was not affected by parity
