title: [Extrauterine pregnancy following in vitro fertilization, 2 of these associated with a developing intrauterine pregnancy].
abstract: Five cases of extra-uterine pregnancy occurred after in vitro fertilisation and embryo transfer. The case histories are given. All pregnancies occurred in the ampullary portions of the tubes. In two of the cases there was an on-going intra-uterine pregnancy as well as the ectopic. After the extra-uterine pregnancy had been operated on the intra-uterine pregnancies continued normally to term. In considering the tubal physiology the authors attempt to draw conclusions about the factors causing ectopic pregnancies after in vitro fertilisation.
