[Comparison of 2 artificial insemination technics. (Sperm tubal perfusion and intrauterine insemination)]

In 1991 Kahn et al, described a method of intrauterine Insemination called Fallopian Tube Sperm Perfusion (FSP) using 4.0 ml for the insemination volume, unlike the classic Intrauterine Insemination (IIU) in which insemination volume is 0.5 ml. The aim of this study is to compare pregnancy rate per cycle in both technics. Between August 1993 and January 1994, 60 couples with infertility were studied, 131 ovarian stimulation cycles were done, 95 with IIU and 36 with PTE. 18 clinical pregnancies occurred, 11 with IIU and 7 with PTE, for a pregnancy rate per cycle of 11.5% for IIU and 19.4% for PTE. This result confirms the reports by Kahn. PTE represents a new possibility for the treatment of different etiology infertility.
