[Human in vitro fertilisation and embryotransfer: first results at the 2nd department of obstetrics and gynaecology, university of vienna (author's transl)].
Methods and Results of human in vitro fertilisation at the 2nd Department of Obstetrics and Gynaecology, University of Vienna are reported. Applying preparations of media and culture techniques according to Edwards et al. no satisfactory results could be achieved: only 3 out of 11 preovulatory oocytes were fertilised, no cleavages occurred. Using modified Ham's F 10 medium according to Lopata et al. fertilisation could be observed in 60% as well as regular cleavages in 40%. 5 Embryotransfers have been performed in the 8 cell or in the 16 cell stage respectively. No implantation occurred in 4 of these, in one case evidence for a transient implantation could be proved by an increased activity of SP1 and HCG beta. In this case obviously postimplantation death occurred resulting in a bleeding 16 days after oocyte recovery. Possible reasons for failures in fertilisation and cleavage as well as possibilities for improving the rate of reimplantation are discussed.
