FALLOPIAN-TUBE SPERM PERFUSION HAS NO ADVANTAGE OVER INTRAUTERINE INSEMINATION WHEN USED IN COMBINATION WITH OVARIAN STIMULATION FOR THE TREATMENT OF UNEXPLAINED INFERTILITY

In this prospective randomized study we treated 60 couples with unexpl ained infertility with a combination of ovarian stimulation and either intrauterine insemination (IUI) or fallopian sperm perfusion (FSP). I n the IUI we used a volume of 0.5 mi of inseminate and in the FSP a vo lume of 4 mi. The demographic characteristics of the patients, the sti mulation parameters and the sperm data were not statistically differen t between the two groups. The pregnancy rate per cycle was 16.2% in th e IUI group and 14.5% in the FSP group and the pregnancy rate per woma n was 40 and 36.7%, respectively (not statistically different). We con clude that IUI and FSP are equally effective in the treatment of coupl es with unexplained infertility.
