Sexual Well-Being After Bariatric Surgery Assessed with New Sexual Satisfaction Scale: A Case-Matched Study of Men...

Severe obesity is associated with lower health-related quality of life, including sexual health. Metabolic and bariatric surgery (MBS) is well-known for its benefits in weight loss and the resolution of obesity-related comorbidities, but its impact on sexual satisfaction remains less documented. Obesity can negatively affect sexual health through hormonal imbalances, lowered self-esteem, and physical limitations. This study aims to evaluate differences in sexual satisfaction following MBS using validated sexual health assessment tools.

This case-matched study involved patients awaiting MBS (preoperative group) and those at 1-year follow-up (postoperative group). Participants were matched by age and preoperative BMI. Sexual satisfaction was measured using the New Sexual Satisfaction Scale (NSSS), along with gender-specific tools: the Female Sexual Function Index (FSFI) and the International Index of Erectile Function (IIEF). Statistical analysis was performed using t-tests, Mann-Whitney tests, and χ² tests.

After matching, 190 pairs were analyzed based on gender. Postoperative patients reported a 24% higher NSSS score compared to preoperative patients (p < 0.001). Male participants showed significant improvements in all IIEF domains except orgasmic function, with the greatest improvement in erectile function. Female participants demonstrated a 20% higher FSFI score, with notable improvements in arousal and desire but not pain.

There are significant differences in sexual satisfaction before and after MBS in both men and women. Future studies should focus on the long-term sustainability of these effects and the role of psychological support in enhancing sexual well-being post-surgery.
