[Pregnancy following in vitro fertilization and intratubal embryo transfer].

The intratubar embryotransfer is a variation of the in vitro fertilization, where the procreated preimplantation-embryos are not transferred into the cavum uteri but the tube(s). The intracavitar embryotransfer is the only possibility to treat irreparable tubar sterility in contrary to sterility not caused by the tubes where the transfer can be effected directly into the tubes. Considering the gamete intrafallopian transfer (GIFT) one can assume, that the tubes are the best physiological place for the very young embryo's evolution. In opposition to the GIFT-method the embryotransfer into the tubes will be done only if a fertilization was proved: thereby superfluous operations can be avoided and additional diagnostic hints can be gained. The valuable indications are the following ones: idiopathic sterility, certain cases of andrological subfertility and immunological sterility; probably for some kinds of the last indication from the intratubar embryotransfer there will result a special area of application. It is reported about a viable pregnancy after in vitro fertilization and intratubar embryotransfer. The new method is supposed to be called IVF/IT-ET (i.e. in vitro fertilization and intratubar embryotransfer).
