GLP-1s drugs like Ozempic may boost male fertility: study

Key Points:

• Recent research suggests GLP-1 weight loss drugs like Ozempic and Mounjaro may improve male fertility markers, including testosterone levels and sperm quality, by addressing obesity-related hormonal imbalances.
• Obesity lowers testosterone through increased aromatase enzyme activity and reduced sex hormone-binding globulin, creating a cycle that impairs male reproductive health and complicates weight loss.
• Unlike testosterone replacement therapy (TRT), which carries risks and is unsuitable for some men, GLP-1s may restore hormone levels naturally by promoting weight loss and improving metabolic health.
• Studies showed liraglutide increased testosterone and sperm production hormones, semaglutide improved sperm morphology, while dulaglutide had no significant reproductive effects; benefits are thought to be indirect via weight loss.
• Researchers emphasize that current evidence is limited and varied, urging larger studies to confirm GLP-1s' impact on male fertility and cautioning against using these drugs solely for fertility enhancement.
