We herein report clinical assessments of efficacy and side effects of T replacement therapy (TRT) in men with late-onset hypogonadism (LOH). The study included 56 patients who were diagnosed with LOH and treated with TRT for at least 6 months at our institution. Age, ageing male symptom (AMS) scale, and androgen decline in the ageing male (ADAM) questionnaires were examined. Fasting blood samples were analysed for sex hormones, total cholesterol (TC), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) cholesterol, triglycerides (TG), aspartate aminotransferase (AST), alanine aminotransferase (ALT), γ-glutamyl transpeptidase (γ-GTP), red blood cell count (RBC), haemoglobin (Hb), haematocrit (Ht), and prostate-specific antigen (PSA). Total and psychological symptoms scores were measured by the AMS scale and the ADAM questionnaire score, demonstrating that the sum of positive responses to the questions were significantly improved after TRT (P < 0.05). TC, HDL, and LDL cholesterol, TG, AST, ALT, γ-GTP, RBC, Hb, Ht, and PSA were not significantly different between before and after TRT. Although TRT for men with LOH may cause favorable changes in psychological conditions, it may not have effects on lipid metabolism, liver function, RBC, and PSA level.
