Serum Total Testosterone Concentrations in the US Household Population from the NHANES 2011–2012 Study Population

Abstract

TotalT patterns were different among age groups in men compared with previous NHANES cycles. Covariate-adjusted totalT values peaked at age 55-60 years in men, which appeared to be consistent with the increased use of exogenous testosterone. Differences among race/ethnic groups existed and appeared more pronounced in children than adults.
