Changes of variables in 2 years were calculated (data of follow-up minus those of baseline). Testosterone levels were increased significantly, whereas job demands and somatic symptoms were reduced significantly, at follow-up. Changes in testosterone levels were negatively associated with changes in total andropause symptoms, psychological symptoms, and sexual symptoms (standardized β = −0.27, −0.24, and, −0.29, p
