[Clinical study of sperm intro-fallopian transfer].
To explore the new technique of assistant pregnancy, we transferred sperm into fallopian tubes by laparoscopy Via an operation named sperm intra-fallopian transfer (SIFT). Twenty-nine infertile women (eighteen patients in natural menstrual cycle group, the others in the group of stimulated ovulation cycle) had their fallicle development with B ultrasonic scanning monitored. Patients were examined by laparoscopy before ovulation, then prepared sperm was transferred into fallopian tubes. Amony twenty-nine patients who had SIFT, three were pregnant in the operation month. The rate of pregnancy in operation month was 10. 3%, The rate of pregnancy during six months after SIFT was 31.0% (9 cases). Amony fifteen patients with "real" unexplained infertility, the rate of pregnancy during six months after SIFT was 46.7%. This preliminary result, showed that on the basis of skilled technique of laparoscopy, SIFT is a new, simple, safe, economic and effective method in treating infertility.
