Neither the percentage in the previous use of contraceptive pills nor the distribution of the time interval between the discontinuation of the pill and conception has shown any significant difference in twins and control singletons. Twin conception within one month after discontinuation of the norethynodrel type pill, however, was significantly more frequent, whereas after the use of the linestrenol type, it was lower.
