SI conversion factors: To convert testosterone to nmol/L, multiply values by 0.0347
Attributes shown as mean (SD) for continuous variables and N (%) for ordinal variables.
By linear regression with adjustment for age and race, with the exception of strata of testosterone levels, which were tested by an unadjusted nonparametric trend test.
The cutoff of 348 ng/dL represents the lower limit of the reference range for normal testosterone levels, based on data from the Framingham Heart Study (see Bhasin S, Pencina M, Jasuja G, et al, J Clin Endo Metab. 2011; 96: 2430–2439.).
N = 18 for AAS users because of missing data
Scores on Erectile Function, Orgasmic Function, and Intercourse Satisfaction, as well as Total Score, are restricted to men reporting at least one sexual partner in the past month (N = 15 former AAS users and 32 non-users).
