Fish Oil Supplementation to Improve Male Fertility

By Robin Miller RDN

Studies suggest that infertility affects approximately 15% of all couples, and although conventional wisdom suggests that infertility is a female issue, the reality is approximately 40% to 50% of fertility issues are due to male factors.  Much research suggests that a healthy diet rich in certain nutrients, such as omega-3 fatty acids, antioxidants, other vitamins, specifically, vitamin D and folate, and low in saturated fat and trans–fat is associated with good semen quality. Fish, shellfish, other seafood, poultry, cereals, vegetables, fruits, low-fat dairy, and skim milk have been found to be positively associated with several semen parameters as well. Fish and fish liver oil in particular also contain other essential nutrients, that have been associated with better semen quality. With that said, there is now new research and data focused on the intake of fish oil supplements and testicular function as measured by semen quality and reproductive hormone levels. 


After examining data from nearly 1,700 young men, researchers determined that fish oil supplementation was associated with a higher sperm count and improved levels of hormones, specifically lower FSH and LH levels; higher free testosterone to LH ratio that contribute to male fertility, according to the report published in JAMA Network Open. 

However, the amount of fish oil the men in the study took was wide-ranging, so there is no specific quantity that can be suggested from this study. Furthermore, because it’s an observational study, we can’t assume a causal or contributing relationship between fish oil supplements and positive outcomes; a double-blind, randomized, placebo-controlled study is the preferred method of research to support a positive correlation. 

In the meantime, most everyone can benefit from more fish in our diets! Incorporate wild, organic, preferably low-mercury fish, such as wild salmon, shrimp, tilapia and whitefish to name a few, into your diet 1-2 a week. Try swapping out a deli meat sandwich with a tuna sandwich or a steak for a piece of wild salmon during the week and you will be naturally getting in some healthy fish oil along with tons of other nutrients, like vitamin D, iron, zinc and magnesium that support fertility. If fish is not your jam, try supplementing a high-quality fish oil supplement to achieve optimal benefits.
