title: [Contraception with the Lippes Loop D with or without contraceptive foam (author's transl)].
abstract: Contraception with Lippes Loop D was compared in 1 group of women (N 172) who used a spermicidal preparation with intercourse and a second group (N 190) who used no spermicidal preparation. In the group with a Lippes Loop and a spermicidal preparation, there were 1.2% unplanned pregnancies compared to 6.4% unplanned pregnancies without spermicidal preparation. This combined method approaches the reliability of oral contraception. The third group of women who used a spermicidal preparation erratically is not comparable in the statistical sense to the other two groups. However in this third group there were less unwanted pregnancies than in the group without the use of spermicidal preparation.
