title: [Triple extra-uterine pregnancy following in vitro fertilization and embryo transfer].
abstract: The article reports on an ectopic pregnancy after IVF/ET that was characterized by the simultaneous nidation of three of the four transferred pre-implantation embryos in both (heavily damaged) Fallopian tubes. The ectopic nidation not only in one of the Fallopian tubes must be seen as a pointer to the importance of active mechanisms of transport from the cavum into the Fallopian tubes. Therefore it is unlikely that ectopic pregnancies after IVF/ET--even if the technique is satisfactory--can be avoided completely. In view of the fact that several IVF treatments were performed in vain, the nidation of three of the four transferred embryos must be interpreted as supporting the theory that the conditions in the Fallopian tubes are more favourable for the development of the human pre-implantation embryos.
