[Clinical aspects of 7 pregnancies following in vitro fertilization and embryo transfer (IVF/ET)].
Between September 1, 1983 and June 15, 1984 69 patients were treated by in-vitro fertilization as part of a clinical research project. The scientific questions were aimed at optimizing the principal methodological aspects of the new technique. One hundred and sixty-nine follicle punctures were performed under laparoscopic or ultrasonographic control. A total of 207 preovulatory oocytes were obtained, 57 of which were transferred to the uterus as cleaving embryos following in-vitro fertilization. Seven clinical pregnancies were diagnosed. Two resulted in spontaneous abortion in the fifth and sixth week of gestation, the remaining five as three single and two twin births. The infrastructure of reproduction medicine has been broadened successfully within a short time. Considering the results of current clinical and experimental research, the efficiency of the methods used is likely to be improved.
