Objectives: We aimed to investigate the effects of bariatric surgery on the sexual functions in both genders by comparing Female Sexual Function Indexes (FSFI) and International Index of Erectile Function (IIEF) scores with the physical, hormonal and biochemical findings after the Laparoscopic Adjustable Gastric Band (LAGB) procedure of morbidlyobese male and female patients.Methods: Obese patients between 18 and 65 years of age who underwent bariatric surgery and continued their followup visits were included in the study. At the postoperative 6th month, FSFI and IIEF surveys were performed to the LAGBpatients. Biochemical and hormonal tests were evaluated.Results: At the postoperative period, a significant decrease was detected in the BMI levels of both male and femalegroups in comparison to the preoperative period (p<0.01). There was no significant difference in the FSFI, IIEF, IIEF-5and IIEF-6 scores (p>0.05); however, there was a quantitative increase at the score levels. A negative correlation wasdetected between BMI and FSFI, IIEF, IIEF-5 and IIEF-6 scores.Conclusion: Although there was no significant difference in the sexual functions of the patients who underwent LAGBoperation in the early period, the long-term follow-up of the patients was become more of an issue.
