126 Relationship Between Sexual Function Improvement and Treatment Satisfaction by TRT in LOH Patients

ABSTRACT Introduction In the treatment of LOH (late-onset hypogonadism) syndrome, TRT (testosterone replacement therapy) is effective for various LOH related symptoms including sexual function. However, among Japanese population, sexual desire is not always strong in elderly men. Even if the patients do not have opportunities of sexual intercourse, TRT may still be beneficial for other symptoms derived from LOH syndrome. Objectives To examine patients’ satisfaction by TRT, we examined the relationship between TRT effect on sexual function and whole treatment satisfaction in our patient cohort. Methods Patients who have LOH symptoms and low serum free-testosterone (FT) levels were diagnosed as LOH syndrome. FT was diagnosed as “low” when <8.5pg/ml, while diagnosed as “borderline” when 8.5-11.8pg/ml. For TRT, testosterone enanthate 250mg/2-4weeks was given for more than 6 months. SHIM (Sexual Health Inventory for Men) score and our original questionnaire asking whether they are satisfied with the treatment were examined. Results Median patients’ age was 54 years (n=95). Before treatment, total testosterone was 4.5±1.8ng/ml and free testosterone was 6.2±2.3pg/ml. The majority of chief complaint before treatment were psychological or somatic symptoms. After treatment, SHIM score showed significant improvement in all questions of 1 to 5, and total SHIM score increased from 6.4 to 9.4. The number of patients who have few opportunities for sexual intercourse (0 point for SHIM Q3.4.5) decreased from 66% to 48% after treatment. Using the questionnaire for patients’ satisfaction, 71% were classified into the effective group. The number of patients who still had few opportunities of sexual intercourse after treatment was 39% in the effective group and 71% in the ineffective group. Conclusions From the point of patient satisfaction, TRT for LOH syndrome was effective in 71% of patients. Almost 40 percent of the patients who were satisfied with the treatment answered that there were few opportunities of sexual intercourse even after treatment. The improvement in sexual function may not be always required in a cohort of our patient population. Disclosure Work supported by industry: no.
