摘要
Objectives: To assess erectile function in middle-aged and older men with asexuality status and further analyze their specific reasons for this condition. @@@ Subjects and Methods: Men who had regular sexual intercourse attempts (sex frequency >= 1 time per month) were classified into mild erectile dysED), moderate to severe ED and non-ED according to International Index of Erectile Function-5, and men having no sexual intercourse attempts for at least 6 months were defined as having an asexuality status. The risk factors associated with ED were collected in a sample of 1,531 Chinese men aged 40 to 80 years, and the self-report reasons for asexuality were recorded in asexual cohort individually. Comparative analyses and multivariate regression models were conducted among these groups. @@@ Results: The prevalence rates of ED and asexuality status were 49.9% and 37.2%. The asexuality status group had higher risk factors than the moderate to severe ED group in terms of old age (age >= 65, adjusted odds ratio (OR) 17.69 versus (Vs.) 7.19), diabetes (crude OR: 2.40 Vs. 2.36) and hypertension (crude OR: 1.78 Vs. 1.72). The specific reasons for the asexuality status were "erectile difficulty" (52.9%), "do not care about sexuality'' (53.5%)'', "no longer necessary to have sexuality at this age" (47.7%), "severe stress" (44.4%), "severe fatigue" (26.3%) and "masturbation" (26.9%). @@@ Conclusions: Men with an asexual status suffer from higher risk factors for ED than men with moderate to severe ED. The majority of this asexual status could be attributed to a full ED, although the reasons for this transient asexuality also involved sexual attitudes and interests, sexual partners and masturbation.
