Early experience with gamete intrafallopian transfer at Ramathibodi Hospital

This report summarises the result of the GIFT program at Ramathibodi Hospital during 1990-1991. There were 35 treatment cycles in 34 infertile couples. The age of the females varied from 29 to 41 years. Duration of infertility was 3 to 10 years. GIFT was performed during diagnostic laparoscopy in 26 cycles (78%). Other indications were endometriosis (5 cycles), concurrent with myomectomy (3 cycles) and unexplained infertility (1 cycle). Two cases received CC+HMG for superovulation, the others had GnRHa+HMG. Transvaginal ultrasound guided oocyte pick up yielded 2 to 10 oocytes (mean 5.8 oocytes per cycle). Two to 8 oocytes were transferred. All patients received progesterone or HCG for luteal support. In cases of diagnostic laparoscopy, the findings were normal (10 cases), endometriosis (7 cases), pelvic adhesion (6 cases) and myoma uteri 3 cases). No pregnancy was achieved among 18 GIFT cycles performed in 1990. In 1991, after changing some instruments and methods, there were 5 pregnancies out of 17 GIFT cycles (29%). The factors that influenced the outcome were good selection of instruments and method, maturity of oocytes and semen parameters.
