Association Between Dietary Intake of Omega-3 Fatty Acids and Serum Testosterone in Adult Males: Results From NHANES 2011-2016 and 2021-2023.

ABSTRACT: Mounting research reports that omega-3 fatty acids (Omega-3) may help improve health, but research on Omega-3 and male testosterone is limited. Our study included males aged ≥ 18 years in the 2011-2016 and 2021-2023 National Health and Nutrition Examination Survey. Multivariable regression analysis and generalized additive models and smooth curve fitting were used to explore the association between dietary intake of Omega-3 (including total Omega-3, docosahexaenoic acid [DHA], eicosapentaenoic acid [EPA], alpha linolenic acid [ALA], docosapentaenoic acid [DPA], and stearidonic acid [SDA]) and male testosterone. Subgroup analyses were performed according to body mass index (BMI) type. 8686 participants were included. Multivariable linear regression found that only DPA exhibited a significan
