Efficacy of nasal continuous positive airway pressure on patients with OSA with erectile dysfunction and low sex hormone levels.
This study aimed to test the hypothesis that erectile dysfunction (ED) is common in men with obstructive sleep apnea (OSA). We also assessed the efficacy of continuous positive airway pressure (CPAP) treatment for ED and sex hormone levels in patients with severe OSA and ED.



A total of 153 OSA patients and 60 healthy controls were enrolled in this study. The International Index of Erectile Dysfunction-5 (IIEF-5) score was obtained, and blood samples were collected for analysis of sex hormones after polysomnography. The IIEF-5 score, sex hormone levels, and polysomnographic parameters were re-evaluated in 32 patients with severe OSA and ED after 1 month of CPAP treatment.



The present study showed that the prevalence of ED was 47.1% in all cases and only 13.3% in controls, and a lower sex hormone levels was presented in OSA patients. OSA patients with ED had greater severity of disease, and lower serum levels of follicle stimulating hormone (FSH) and testosterone than OSA patients without ED (p < 0.05). After CPAP therapy, there was a significant increase in the IIEF-5 score, and serum levels of FSH, luteinizing hormone, and testosterone, were elevated compared with baseline levels (p < 0.05). Multivariate regression analysis indicated the serum level of testosterone had impact on the ED.



OSA patients had lower sex hormone levels and a higher occurrence of ED than controls, and serum level of testosterone had effect on ED. CPAP treatment ameliorated the symptoms of ED and elevated serum levels of FSH, luteinizing hormone, and testosterone.
