THE ROLE OF GAMETE INTRAFALLOPIAN TRANSFER (GIFT) AND TUBAL EMBRYO-TRANSFER (TET) IN THE TREATMENT OF PATIENTS WITH PATENT TUBES ASSOCIATEDWITH MALE-INFERTILITY FACTOR

Purpose: The relative effectiveness of gamete intrafallopian transfer (GIFT) and tubal embryo transfer (TET) combined with superovulation in the treatment of infertile patients with patent tubes were compared. Four hundred fifty consecutive cycles were divided into two periods. D uring the first period (216 cycles), the only technique employed was G IFT, couples being divided into two groups: group A, couples with norm ospermic partners (118 cycles); and group B, couples with male inferti lity factor (98 cycles). During the second period (234 cycles), 140 cy cles of GIFT were performed in couples with normospermic partners (gro up C). TET was utilized in 94 cycles (group D), in the case of couples with male infertility factor. Results: Results demonstrate that the p regnancy rate with GIFT in the case of oligoasthenospermic partners (g roup B) is significantly lower than that of normospermic partners (gro ups A and C) (P = 0.0001) and than that with TET in the case of oligoa sthenospermic partners (group D) (P = 0.0001). Conclusion: The implant ation rate is also significantly different between these groups (B vs A, P = 0.0001; B vs C, P = 0.0001; B vs D, P = 0.01).
