title: The role of gamete intrafallopian transfer (GIFT) and tubal embryo transfer (TET) in the treatment of patients with patent tubes associated with male infertility factor.
abstract: OBJECTIVE
  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. During the first period (216 cycles), the only technique employed was GIFT, couples being divided into two groups: group A, couples with normospermic partners (118 cycles); and group B, couples with male infertility factor (98 cycles). During the second period (234 cycles), 140 cycles of GIFT were performed in couples with normospermic partners (group C). TET was utilized in 94 cycles (group D), in the case of couples with male infertility factor.
  
  
  RESULTS
  Results demonstrate that the pregnancy rate with GIFT in the case of oligoasthenospermic partners (group B) is significantly lower than that of normospermic partners (groups A and C) (P = 0.0001) and than that with TET in the case of oligoasthenospermic partners (group D) (P = 0.0001).
  
  
  CONCLUSIONS
  The implantation 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).
