title: The return of fertility following discontinuation of oral contraceptives in Thailand.
abstract: The return of fertility following discontinuation of oral contraception was studied in a survey of 437 Thai women who stopped taking the pill to have a planned pregnancy. Conception rates were reduced during the first 2 months after stopping the pill, and the median delay prior to conception was approximately 3 months. This delay was shorter for nulligravid women. Most women (94.3%) became pregnant within 2 years of stopping the pill. There was a cyclic pattern in the monthly pregnancy rates with peak rates around 3 and 6 months after discontinuing contraception. These findings are similar to those reported for Caucasian women.
