Danish and US scientists looked at the medical records of 1,679 young Danish men aged around 18, and say blokes who took fish oil supplements had higher sperm counts, higher semen volume, bigger testicles and higher testosterone levels, compared with men who didn't take the capsules. And the more fish oil supplements the men took, the higher their sperm counts, semen volume and testosterone levels were. This type of study cannot show cause and effect, but the fact that increasing doses of fish oil meant even bigger and better balls suggests there could be a causal link.

Observational Study Explores Fish Oil Supplements, Testicular Function in Healthy Young Men
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.
