To assess prevalence of condom-associated erection loss and to identify correlates of erection loss among men attending a sexually transmissible infections (STI) clinic.
Men (n = 278) attending an STI clinic responded to an anonymous questionnaire aided by a CD recording of the questions. The sample was screened to include only men who had used a condom during penile-vaginal sex at least three times in the past 3 months. Erection loss was assessed for 'the last three times a condom was used'.
The mean age of the participants was 23.7 years (s.d. = 4.1); 37.1% of the men reported condom-associated erection loss on at least one occasion. Men who had reported condom-associated erection loss were also reported having more frequent unprotected vaginal sex (P = 0.04) and were less likely to use condoms consistently (P = 0.014) than men without erection loss. Men with erection loss were also more likely to remove condoms before sex was over (P = 0.001). Age and race/ethnicity were not associated with erection loss. In multivariate analysis, three significant statistical predictors were identified: low self-efficacy to use condoms (P = 0.001); problems with 'fit or feel' of condoms (P = 0.005); and having more than three sex partners during the previous 3 months (P = 0.02).
Condom-associated erection loss may be common among men at risk for STIs. This problem may lead to incomplete or inconsistent condom use. Men may be more likely to experience condom-associated erection loss if they lack confidence to use condoms correctly, if they experience problems with the way condoms fit or feel, and if they have sex with multiple partners.
评估在性传播感染(STI)诊所就诊的男性中与避孕套相关的勃起功能丧失的患病率,并确定勃起功能丧失的相关因素。
在性传播感染诊所就诊的男性(n = 278)通过问题的CD录音辅助回答一份匿名问卷。样本筛选标准为仅纳入在过去3个月中至少有三次阴茎-阴道性交时使用过避孕套的男性。针对“最近三次使用避孕套时”评估勃起功能丧失情况。
参与者的平均年龄为23.7岁(标准差 = 4.1);37.1%的男性报告至少有一次与避孕套相关的勃起功能丧失。报告有与避孕套相关的勃起功能丧失的男性比没有勃起功能丧失的男性报告有更频繁的无保护阴道性交(P = 0.04),并且持续使用避孕套的可能性更小(P = 0.014)。有勃起功能丧失的男性在性交结束前更有可能摘掉避孕套(P = 0.001)。年龄和种族/民族与勃起功能丧失无关。在多变量分析中,确定了三个显著的统计学预测因素:使用避孕套的自我效能感低(P = 0.001);避孕套“贴合度或感觉”有问题(P = 0.005);以及在过去3个月中有超过三个性伴侣(P = 0.02)。
与避孕套相关的勃起功能丧失在性传播感染风险男性中可能很常见。这个问题可能导致避孕套使用不完整或不一致。如果男性缺乏正确使用避孕套的信心、如果他们在避孕套的贴合度或感觉方面有问题以及如果他们与多个性伴侣发生性行为,那么他们更有可能经历与避孕套相关的勃起功能丧失。
