Post-pill anovulation.
Basal temperature records were maintained by 346 women after ceasing to take oral contraceptives; 167 had ceased using combined and 179 had ceased using low-dose sequential formulations. In the first cycle after withdrawal of low-dose sequential pills, 11 (6%) women failed to ovulate and ovulation was delayed in five cases. Short luteal cycles occurred in 14 subjects. In 83% of the subjects there was no disturbance of ovulation. In the first cycle after withdrawal of combined oral contraceptives, 49 (30%) women failed to ovulate and ovulation was delayed in 29 cases. A short luteal phase was observed in 26 subjects. In only 38% of the subjects was there no disturbance of ovulation. The minimal disturbance to ovulation in the cycle after the withdrawal of low-dose sequential formulation indicates that this type of oral contraceptive carries little risk of producing post-pill infertility. Women under the age of 21 years were anovulatory nearly twice as frequently as older women after ceasing to use combined oral contraceptives.
Post-pill infertility.
One hundred and fifty-one nulligravid women and 63 parous women stopped taking low-dose sequential oral contraceptives in order to become pregnant. During the first post-Pill cycle, 39% of the nulligravid and 54% of the parous women conceived. These figures have been compared with data from the Royal College of General Practitioners survey in England, in which 13% of nulligravid and 17% of parous women conceived in the first cycle after ceasing to take combined oral contraceptives. The percentage of nulligravid women not pregnant six months after withdrawal of low-dose sequential formulations was 19% compared with 32% after withdrawal of combined oral contraceptives. The corresponding figures for parous women were 5% and 21%. Available data suggest that after withdrawal of low-dose sequential oral contraceptives, the incidence of post-Pill infertility is lower than that after withdrawal of combined oral contraceptives. The extent of this difference is 16% three months after withdrawal of the Pill and 10% six months after attempting pregnancy.
