Observational study explores fish oil supplements, testicular function in healthy young men

January 17, 2020

What The Study Did: An observational study of nearly 1,700 young healthy Danish men looked at how fish oil supplements were associated with testicular function as measured by semen quality and reproductive hormone levels. Limitations of this study include a lack of information on the actual concentration of omega-3 fatty acids in the fish oil supplements self-reported by the men. Researchers suggest randomized clinical trials are needed.
