Fish oil linked to sperm health

Researchers have recently studied over 1,600 Danish men in a fertility study and discovered that taking fish oil supplements may increase sperm counts, semen volume, and improve testicular health in men.

The men in the study who took fish oil supplements for three months had a noticeably higher sperm count than those who didn’t, produced a greater proportion of morphologically normal sperm, had a higher than average semen volume, as well as a larger than average testicular size.

In addition to improved sperm concentration and quality, the men who took the fish oil supplements also had significantly lower follicle stimulating hormone (FSH) levels and lower luteinising hormone (LH) levels.

FSH and LH are hormones produced by the anterior pituitary gland and play an essential role in maintaining healthy sperm production. Elevated FSH and LH levels have been associated with azoospermia, which means that there is no sperm found in the semen.

The study also found that the effect of the fish oil was “dose dependent”, which means that the men who took the fish oil supplements for more than 60 days had a significantly better testicular function than the men who didn’t take the supplements as often.

Although these are preliminary results, it was found that the intake of fish oil supplements was associated with improved testicular function and once again shows the benefits of a fish-rich diet. As an added bonus, fish oil has also been proven to support healthy eye function, cardiovascular health, reduced joint inflammation and brain function.
