This systematic review and meta-analysis evaluated the effects of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) on male sexual function in 848 patients. Both procedures were associated with improvements in sex hormone-binding globulin and testosterone levels. Notably, SG showed significant enhancements in erectile function (SMD: 1.38) and sperm concentration (SMD: 0.91), while RYGB did not demonstrate significant changes.
Key findings
- SG significantly improved erectile function (SMD: 1.38, p = 0.0002).
- SG also showed significant improvements in sperm concentration (SMD: 0.91, p < 0.00001).
- RYGB did not show statistically significant changes in erectile function (SMD: 0.62, p = 0.07).
- RYGB also did not demonstrate significant changes in sperm concentration (SMD: -0.01, p = 0.95).
Why it matters
Understanding the impact of bariatric surgery on male sexual function is crucial, as obesity-related sexual dysfunction can affect quality of life. This research highlights the potential benefits of SG over RYGB in improving sexual health parameters.
What to keep in mind
Direct comparative analyses between RYGB and SG were not performed, limiting conclusions about their relative efficacy.
