[First results of in vitro fertilization in the human (author's transl)]

In vitro fertilization was studied in human egg cells obtained by laparoscopy. In 1979 our studies included 65 women with long term infertility and proven tubal factor infertility. The primary diagnostic laparoscopy established disease of uterus, tubes and ovaries and was used to correct pathology. Lysis of adhesions was used to make aspiration of a spontaneous mature follicle for in vitro fertilization easier. The aspiration laparoscopy was performed after stimulation with HMG and HPG. Our prerequisite was the presence of at least one ovary with ovulatory cycles. In almost all cases the ovaries wer accessible only following lysis of ovarian and tubal adhesions. Aspiration of the follicle was successful in 55 of the patients stimulated with HMG/HCG. In 10 cases no follicle for aspiration was available. In 21 cases one egg cell was found. In 11 cases more than one egg cell was found. The maximum was 8 egg cells in one patient. In 34 patients only cumulus cells were aspirated following stimulation. Under the in vitro fertilization conditions described in this paper it was possible to obtain twice a pro-nucleus formation, twice the two cell and twice the four cell stage following conjugation with sperm of the partner. Of the 47 patients with a tubal occlusion, 30 were isthmic or utero-isthmic and 17 tubal occlusions were peripheral. In 15 patients chromo-tubation showed recanalization.
