A study including 1679 young men in Denmark found that fish oil supplements were associated with higher semen volume and total sperm count, larger testicular size, and a higher calculated free testosterone level. The higher the dose of the supplement, the higher the fertility in these men.
Conclusions and Relevance: The study concluded that fish oil supplements significantly improved fertility through improving the structure and function of the reproductive organs in the body.
How do Omega 3 fatty acids help fertility?
Fertility in men and women significantly depends on the nutritional status of both partners. In addition, fertility is adversely affected by inflammation. Omega-3 fatty acids are nutrients that play a very important role in the function of hormones and in maintaining the structure and performance of cells of multiple organs including the reproductive system. They are also important in reducing inflammation, which helps with fertility. See the figure below to understand the different factors that impact fertility.
