Sleep disturbance as a clinical sign for severe hypogonadism: efficacy of testosterone replacement therapy on sleep disturbance among hypogonadal men without obstructive sleep apnea.

ABSTRACT

OBJECTIVE: The present subanalysis of the EARTH study investigates the effects of one year testosterone replacement therapy (TRT) on sleep disturbance among hypogonadal men without obstructive sleep apnea. METHODS: Sleep disturbance was defined as three or more points in question 4 of the aging males symptoms (AMS) questionnaire. All participants completed the AMS scale, International Prostatic Symptoms Score (IPSS), Sexual Health Inventory for Men (SHIM) and Short Form 36 (SF-36) health survey at baseline and after 12 months. Sexual symptoms were also evaluated based on three AMS subscores (Q15, 16 and 17). RESULTS: We identified 100 patients with sleep disturbance, of whom 48 (24 each in the TRT and control groups) were ultimately included for analysis. All SF-36 categories , AMS scale, IPSS and SHIM score subdomains were significantly worse in patients with sleep disturbance than in those without disturbance. Statistically significant differences in sleep disturbance, erectile symptoms, sexual desire and some domains of the SF-36 were observed between the TRT and control groups after 12 months. CONCLUSION: Sleep disturbance may be one of the clinical signs for severe hypogonadism. Moreover, TRT improved sleep conditions, sexual function and quality of life among hypogonadal men with sleep disturbance.
