[The pregnancy occuring during oral contraception or intra uterine device (i.u.d.) (author's transl)].

It seems possible to answer most of the questions asked by our patients after failure of the contraception. The pill stopped within the first five weeks of gestation has never been responsible of congenital malformations. When this treatment is prolonged during the pregnancy, a risk of masculinisation of female fetus exists. No severe malformations has been reported. The I.U.D. does not play a role in the frequency of tubal pregnancy. The I.U.D. must be removed when a pregnancy occurs to prevent the risk of sepsis.
