A prospective randomized comparison of sexual function and semen analysis following laparoscopic totally extraperitoneal (TEP) and transabdominal pre-peritoneal (TAPP) inguinal hernia repair

Background With standardization of laparoscopic technique of groin hernia repair, the focus of surgical outcome has shifted to lesser studied parameters like sexual function and fertility. Methods This prospective randomized study was conducted in a single surgical unit at a tertiary care hospital. A sample size of 144 was calculated with 72 in each group (Group 1 TEP and Group 2 TAPP). Primary outcomes measured included comparison of sexual function using BMFSI, qualitative semen analysis and ASA levels between patients undergoing TEP or TAPP repair. Semen analysis and ASA was measured pre-operatively and 3 months post-operatively. Results A total of 145 patients were randomized into two groups, TAPP (73) and TEP (72) patients. Both the groups were comparable in terms of demographic profile and hernia characteristics with majority of the patients in both the groups having unilateral inguinal hernia (89.0% in TAPP group and 79.2% in TEP group). Both the groups showed statistically significant improvement in overall sexual function score (BMFSI) at 3 months; however, there was no inter group difference. Both the groups were also comparable in terms of ASA and qualitative semen analysis. Conclusion Both TEP and TAPP repair are comparable in terms of sexual function and effect on semen analysis. Laparoscopic repair improves the overall sexual functions in patients with groin hernia.
