a Lobular atrophy was assessed by the pathologists using four categories. b The duration of testosterone therapy (TT) significantly correlated with increasing degrees of lobular atrophy (rho = 0.30, 95% Confidence Interval (CI) 0.21, 0.38, adj p < 0.001). c Stromal composition was assessed by the pathologists using three categories. d There was no correlation between duration of TT and stromal composition as assessed by the pathologists (rho = − 0.01, 95% CI − 0.11,0.08, adj p = 0.77)
