Rating (out of 5): 4

Fish and shellfish are known to support the male reproductive system primarily due to their rich content of omega-3 fatty acids, zinc, selenium, and high-quality protein. Multiple scientific studies have highlighted the positive impact of these nutrients on male fertility. For example, omega-3 fatty acids found in fatty fish (such as salmon, mackerel, and sardines) have been shown to improve sperm count, motility, and morphology. Zinc, abundant in shellfish like oysters, is an essential mineral for testosterone production and overall sperm health; deficiencies in zinc are linked to reduced fertility in men. Selenium, also present in various seafood, is associated with improved sperm motility and a decreased risk of male infertility.

Randomized controlled trials and observational studies have provided evidence that regular consumption of fish and shellfish correlates with improved semen parameters. Additionally, the antioxidant properties of certain nutrients in seafood can help protect sperm from oxidative stress, which is a known contributor to male infertility. While the benefits are more strongly associated with regular dietary inclusion rather than isolated supplementation, there is a solid scientific rationale and growing body of evidence supporting the role of fish and shellfish in maintaining and improving male reproductive health.
