Obstructive sleep apnea affects the sexual function of the male patient / 中华男科学杂志

ABSTRACT

Objective@#To explore the factors influencing the sexual function of the male patients with obstructive sleep apnea (OSA).@*METHODS@#Using Arizona Sexual Experience Scale (ASEX) and Epworth Sleepiness Scale (ESS), we conducted a questionnaire investigation among 81 male patients with OSA aged 40.5 ± 8.6 years and 35 healthy volunteers aged 38.8 ± 10 years. According to the sex drive (SD) score in ASEX, we divided the OSA patients into an SD reduction group (SD score = 4, n = 32) and a non-SD reduction group (SD score <4, n = 49), compared the clinical data and polysomnographic (PSG) indexes, and analyzed the factors influencing SD by evaluating the association of the PSG indexes with the SD score.@*RESULTS@#The OSA patients scored significantly higher than the healthy controls in ESS (8 ± 5 vs 5 ± 4, P <0.05) and ASEX (15 ± 4 vs 10 ± 2, P <0.05), and so did the patients of the SD reduction group than those of the non-SD reduction group in ESS (9 ± 5 vs 6 ± 5, P <0.05) and saturation impair time below 90% (SIT90) (41.01 ± 26.95 vs 21.87 ± 19.03, P <0.05). Multivariate regression analysis revealed that the SD score was significantly correlated with age (β = 0.25, P <0.001) and SIT90 (β = 0.4, P <0.001) in the OSA patients.@*CONCLUSIONS@#OSA affects various aspects of the sexual function, particularly SD, of the patient. The duration of hypoxia and age of the patient are independent risk factors for SD reduction, which can be considered as a main clinical symptom of OSA.
