GLP-1 medications may improve male fertility, study finds

Key Points:

• A 24-week study found that men aged 18 to 65 taking GLP-1 medications, commonly used for diabetes and weight loss, experienced improved testosterone levels, sperm count, and sperm morphology.
• The research suggests that GLP-1s may benefit male fertility, especially in men with high body mass index, potentially offering an alternative to testosterone replacement therapy which can suppress sperm production.
• Experts caution that more studies are needed before GLP-1s can be recommended as a treatment for male infertility, and emphasize the importance of fertility evaluations to understand underlying causes.
• Weight loss from GLP-1s may improve hormone function and reduce inflammation, but sudden or excessive weight changes could negatively impact fertility, highlighting the need for medical guidance.
• Men seeking to improve fertility are advised to adopt healthy lifestyle habits such as balanced nutrition, regular exercise, good sleep, and avoiding smoking and excessive alcohol, while consulting healthcare providers for personalized care.
