While there is literature on erectile dysfunction (ED) and premature ejaculation (PE) in men, conclusive evidence regarding these sexual health issues and potential associated factors in the young, single men who have sex with men (MSM) population is lacking.
The study sought to determine the prevalence and factors associated with PE and ED in young single MSM in the capital of Peru.
This was an analytical cross-sectional study in MSM using an online questionnaire. The presence of ED and PE was assessed using the 5-item International Index of Erectile Function and 5-item Premature Ejaculation Diagnostic Tool questionnaires, respectively. In addition, their association with personal, physical health, and sexual behavior variables was evaluated. Prevalence ratios (PRs) were estimated through regression models.
Premature ejaculation and Erectile dysfunction in MSM.
Of 315 participants, most were between 20 to 29 years of age (71.8%), 43.5% identified as homosexual, 59.1% had between 2 and 5 sexual partners, and 40.6% reported that the duration of their sexual relationship was between 1 and 12 months. The prevalence of ED was 53.3% (95% confidence interval [CI], 47.66%-58.95%), and PE was present in 8.3% (95% CI, 5.46%-11.86%). Factors associated with a higher prevalence of ED were having between 6 and 9 sexual partners (PR, 1.48; 95% CI, 1.05-2.11) and having a sexual relationship lasting 13 to 24 months (PR, 0.70; 95% CI, 0.50-0.98). Furthermore, for each additional year from the onset of the first sexual encounter with another man, the prevalence of PE increased by 7% (PR, 1.07; 95% CI, 1.02-1.13).
These findings suggest that there is a relationship between an increased number of sexual partners and a higher prevalence of ED. It also suggests that relationships that last for some time may have a protective effect against ED.
Strengths include the use of validated instruments, adequate sample size, robust multivariate analysis, and being one of the few studies in Latin America assessing PE and ED in the MSM population. Limitations include the cross-sectional design, nonprobability sampling, and access to participants.
Having more sexual partners is associated with increased ED, while relationships lasting 13 to 24 months are associated with decreased ED. Each additional year from the onset of the first sexual relationship increases the prevalence of PE. These findings can guide the design of health policies and programs tailored to the MSM community to enhance their well-being and sexual quality of life.
虽然有关于男性勃起功能障碍（ED）和早泄（PE）的文献，但在年轻的男男性行为者（MSM）群体中，关于这些性健康问题及其潜在相关因素的确凿证据仍然缺乏。
本研究旨在确定秘鲁首都年轻单身男男性行为者中早泄和勃起功能障碍的患病率及其相关因素。
这是一项针对男男性行为者的分析性横断面研究，采用在线问卷。分别使用5项国际勃起功能指数问卷和5项早泄诊断工具问卷评估勃起功能障碍和早泄的存在情况。此外，还评估了它们与个人、身体健康和性行为变量之间的关联。通过回归模型估计患病率比（PRs）。
男男性行为者中的早泄和勃起功能障碍。
在315名参与者中，大多数年龄在20至29岁之间（71.8%），43.5%为同性恋者，59.1%有2至5个性伴侣，40.6%报告其性关系持续时间在1至12个月之间。勃起功能障碍的患病率为53.3%（95%置信区间[CI]，47.66%-58.95%），早泄的患病率为8.3%（95%CI，5.46%-11.86%）。与勃起功能障碍患病率较高相关的因素包括有6至9个性伴侣（PR，1.48；95%CI，1.05-2.11）以及性关系持续13至24个月（PR，0.70；95%CI，0.50-0.98）。此外，从与另一名男性首次发生性接触开始，每增加一年，早泄的患病率就增加7%（PR，1.07；95%CI，1.02-1.13）。
这些发现表明性伴侣数量增加与勃起功能障碍患病率较高之间存在关联。这也表明持续一段时间的性关系可能对勃起功能障碍有保护作用。
优点包括使用了经过验证的工具、足够的样本量、强大的多变量分析，并且是拉丁美洲少数评估男男性行为者群体中早泄和勃起功能障碍的研究之一。局限性包括横断面设计、非概率抽样以及参与者的获取情况。
拥有更多性伴侣与勃起功能障碍增加有关，而持续13至24个月的性关系与勃起功能障碍减少有关。从首次发生性关系开始，每增加一年，早泄的患病率就会增加。这些发现可以指导针对男男性行为者群体量身定制的健康政策和项目的设计，以提高他们的幸福感和性生活质量。
