Bariatric Surgery Does Not Improve Semen Quality: Evidence from a Meta-analysis

Area of Science:

• Reproductive Medicine
• Metabolic Surgery
• Andrology

Background:

• Obesity is linked to impaired semen quality.
• Bariatric surgery is a treatment for severe obesity.
• The impact of bariatric surgery on male fertility is not well-established.

Purpose of the Study:

• To investigate the relationship between bariatric surgery and semen parameters.
• To determine if bariatric surgery improves semen quality in obese males.

Main Methods:

• A meta-analysis was conducted using data from PubMed, EMBASE, and CENTRAL.
• Included studies evaluated semen parameters before and after bariatric surgery.
• Nine studies with 218 patients were analyzed.

Main Results:

• Bariatric surgery showed no significant effect on sperm volume, concentration, total count, morphology, or motility.
• No significant changes were observed in sperm viability, semen pH, or semen leukocytes post-surgery.
• Overall, bariatric surgery did not lead to improvements in semen quality.

Conclusions:

• Bariatric surgery does not appear to enhance semen quality in obese men.
• Further research may be needed to explore long-term effects or specific patient subgroups.
