A study on conscious or unconscious resistances to contraception in women undergoing induced abortion was conducted on 233 patients receiving abortion services at the Family Planning Center of Bionne, France. A questionnaire was devised for this purpose, and answers were carefully evaluated. Resistance to contraception was caused by moral disapproval of contraception in 57.51% of women, by a strong ambivalence toward the desire to have a child in 51.07%, by fear of the reactions of the social environment in 38.20%, by physical contraindications in 27.90%, and by misinformation in 15.45%. Moreover, 10.30% of interviewed women thought that conception would be impossible at the time of intercourse, 9.87% had not expected to have intercourse, and 0.86% had been forced to have intercourse. Of the 57.51% of women who resisted contraception because of moral disapproval, 67.9% disapproved because of a personal refusal to accept their sexual identity, and 33.57% disapproved on religious grounds. Of the women who refused contraception because of the strong ambivalence toward the desire to have a child 47.05% wanted a child but knew it would have been impossible to keep it for practical reasons, 38.6% needed a proof of their fertility, and 27.72% wanted a pregnancy but not a child. The rationalization of the problems related with contraception refusal does not hide the fact that, in most cases, the refusal stems from emotional conflicts.
