Objective: To compare the effect of laparoscopic salpingectomy and proximal fallopian tubes division on ovarian function after controlled ovarian hyperstimulation. Methods: Seventy six patients undergoing their first IVF-ET cycle were divided into (group 1) 20 patients undergoing laparoscopic salpingectomy, (group 2) 19 patients undergoing proximal tubal division and (group 3) 37 tubal-factor patients without hydrosalpinx as control group. Main outcome measure (s): Ovarian artery pulsatility

... ex (PI), basal follicle-stimulating hormone (FSH) levels before and after surgery, operative time, total dose and duration of IVF stimulation, number of retrieved and fertilized oocyte, and number of embryo transferred. Result (s): No significant differences in mean ovarian artery pulsatility indices among any of the groups before or after surgery. The mean FSH value was similar before and after laparoscopic proximal tubal division. The FSH value significantly increased after laparoscopic salpingectomy. The operative time in the PTD group was significantly shorter than in the salpingectomy group, total dose and duration of stimulation, number of retrived and fertilized oocyte, were not significantly different between group 1, group 2 or control group. Conclusion (s): Laparoscopic salpingectomy or proximal tubal division gives similar responses to IVF-ET cycles. However, proximal tubal division preserved ovarian function.
