One-hundred-and-six gamete intra-fallopian transfer procedures with donor semen

A single attempt of gamete intra-Fallopian transfer was performed in 106 patients, who had previously failed to become pregnant after a certain number of artificial donor inseminations. A maximum of six unselected oocytes were transferred into the tubes. Fifty-five clinical pregnancies (51.9%) were obtained. There were 11 multiple pregnancies (20%) and 10 miscarriages (18.1%). Only one ectopic pregnancy occurred (1.8%). The age of the patients and the previous number of failed inseminations did not have any significant influence on the outcome of the procedure, whereas the number of transferred oocytes had a proportional, significant correlation with the pregnancy rate.
