Testosterone and omega 3 fatty acids.

Many men now have poor semen quality even at a young age.

This research investigated testicular function and semen quality in young and healthy men (Jensen TK, et al., 2020).

The researchers found that the men who supplemented with fish oil omega 3 fatty acids had a significant improvement in testicular function compared to the group not taking any.

There was a significant difference in semen volume and also testicular size in the men taking fish oil supplements compared to the ones not taking any.

Semen volume was higher and testicular size larger when taking fish oil, and it was a larger difference when it was taken for more than 60 days compared to taking it for less than 60 days.
