In the past 50 years, sperm density has fallen by 40%. Spermatozoa from asthenozoospermic (reduced motility or vitality of sperm) and oligozoospermic (reduced number of sperm in the semen) men have decreased concentrations of DHA compared with those from normozoospermic (normal sperm) men.

In a study that evaluated the relationship between dietary fats and semen quality in 99 men, the outcomes showed that higher intake of omega-3 fatty acids was positively correlated with sperm morphology. In another trial, 238 infertile men received daily 1.84 g of EPA and DHA or placebo for 32 weeks; in the omega-3 study group a significant improvement in total sperm count and sperm density was observed. Nutritional supplementation with omega-3 should be considered to improve semen quality.
