Gamete and embryo transfer in conjunction with microsurgical treatment of sterility

: The authors evaluate the results of the programme of transfer of gametes into the oviduct or of embryos into the uterus in conjunction with microsurgery of sterile women. During the period between August 1981 and December 1988 a total of 211 microsurgical operations were made in stimulated cycles. The ovaries were stimulated with clomiphene citrate or in combination with human menopausal gonadotropin. The operation was made 36 hours after administration of human choriogonadotropic hormone. In 146 women at least one oocyte was obtained. A total of 72 gametotransfers into the oviduct were made and in eight, i. e. 11.1%; pregnancy was achieved. Of 43 embryotransfers five pregnancies were achieved, i. e. 11.6%. A total of 13 pregnancies were achieved with four spontaneous deliveries, seven miscarriages and two extrauterine pregnancies. The combination of selected cases of microsurgery of sterility with the IVF programme increases the rate of successful operations without a further burden for the patient, and it extends the possibilities of sterility treatment.
