ĐẶC ĐIỂM HOẠT ĐỘNG TÌNH DỤC VÀ CHỨC NĂNG TÌNH DỤC Ở NAM GIỚI TUỔI 50-69

Abstract

Background: Sexual activity and sexual function in men tend to decline with age. Hospital-based studies have reported a high prevalence of sexual dysfunction in this age group; however, data on the level of sexual activity and sexual function among Vietnamese men aged 50-69 years in the community are still limited. Objective: To determine the prevalence of ongoing sexual activity and sexual function among community-dwelling men aged 50-69 years. Subjects and methods: A cross-sectional descriptive study was conducted on 105 men aged 50-69 years who participated in a community health screening program in Nghia Do Ward, Hanoi. Sexual activity was defined as ongoing sexual intercourse, intimate behaviors, or masturbation. Sexual function was assessed in four domains: sexual desire, erectile function, ejaculation, orgasm, and intercourse satisfaction, using the International Index of Erectile Function-15 (IIEF-15) and the Premature Ejaculation Diagnostic Tool (PEDT) among men who were still engaging in sexual intercourse. Results: Overall, 90.47% of participants remained sexually active (89.5% still had sexual intercourse, 79.0% still had intimate behaviors, and 3.8% reported masturbation). The proportions of participants who still had frequent sexual desire, orgasm, and intercourse satisfaction were 54.2%, 78.7%, and 76.6%, respectively; 77.6% reported moderate-to-high sexual desire. Erectile dysfunction was present in 54.3% of participants, predominantly mild (40.4%). The prevalence of premature ejaculation was low (6.4%). The proportions reporting loss of sexual desire, inability to achieve orgasm, and lack of intercourse satisfaction ranged from 1.1% to 2.1%. Age ≥60 years and diabetes mellitus were independently associated with reduced sexual desire. Conclusions: Most urban Hanoi men aged 50-69 years remained sexually active and maintained sexual function. Erectile dysfunction was the most common sexual disorder, but it was mainly mild, while premature ejaculation and complete loss of desire, orgasm, or intercourse satisfaction were uncommon. Age ≥60 years and diabetes mellitus were independently associated with reduced sexual desire.
