Comparison of adjusted means improvement in each Quality of Sexual Function (QSF) component scores between the STT and placebo groups during the follow-up period of the study: a. QSF-psychosomatic quality of life; b. QSF-sexual activity; c. QSF-sexual (dys)function (-self-report), d. QSF-sexual (dys)function (partner’s view). Treatment with STT (the gray column, N = 27) significantly improved 3 of 4 component scores of sexual function quality in men compared with those of the placebo group (the white column, N = 27), i.e., QSF-sexual activity (p < 0.001), QSF-sexual (dys)function (self-report) (p < 0.043), and QSF-sexual (dys)function (partner’s view) (p = 0.002) from weeks 4, 8 and 12, respectively. There was no significant difference in QSF-psychosomatic quality of life between the STT and placebo groups
