Some clinical results of in vitro fertilization by the Malmö Group, Sweden.

In our in vitro fertilization program, only clomiphene/human chorionic gonadotropin-stimulated cycles have been used, yielding 1.6 preovulatory oocytes/woman at follicle aspiration. The cleavage rate was significantly influenced by the percentage of abnormal spermatozoa and by the percentage of motile spermatozoa in the spermiograms. At embryo replacement, a tilted uterus obtained by a full bladder in the woman simplifies the replacement procedure. In the last 12 months, 47 embryo transfers have been carried out, resulting in five clinical pregnancies. Of these pregnancies, one has proceeded to term, one resulted in a miscarriage, and three resulted in ectopic pregnancies.
