GLP-1 weight-loss drugs linked to improved male fertility in a 24-week study

A CNN Health summary reports that men aged 18–65 with high BMI who took GLP-1 medications (used for diabetes and weight loss) for 24 weeks showed higher testosterone, increased sperm count, and better sperm quality. While findings hint at fertility benefits and potential as an alternative to testosterone therapy, experts caution that more research is needed and results may not apply to all men. Benefits may stem from weight loss and reduced inflammation, but clinicians emphasize fertility evaluations and ongoing healthy lifestyle choices, as weight loss alone does not guarantee improved fertility.
