Summary
After 24 weeks of GLP-1 treatment, men ages 18 to 65 showed higher testosterone, sperm counts, and improved sperm size and shape, according to a study presented by UK researchers.
The findings suggest the diabetes and weight-loss drugs may aid male fertility through weight loss, healthier hormone function, and lower inflammation and metabolic stress that can impair sperm production.
Researchers cautioned the study only included men with high body mass index, so it is unclear whether the benefits would extend to the broader male population or justify first-line infertility treatment.
Doctors also warned rapid fat loss can sometimes suppress fertility signals, and said men trying to conceive should seek a reproductive urologist evaluation and discuss treatment choices with their providers.
The results matter because about 15% of U.S. couples struggle to conceive, and male infertility contributes to more than half of those cases.
