There is high global demand for new methods of male birth control (MBC). However, contemporary evidence regarding men's method-specific attitudes and their determinants is sparse.
Non-sterilized cisgender men ages 18-45 with recent history of female sex partners were surveyed at a large community event in the Midwestern US. We examined variation in participants' willingness to use MBC by method (gel, pill, injection, implant, and vas occlusion), potential side effects, and potential barriers. We estimated crude and adjusted prevalence ratios (aPRs) for associations between participant characteristics and willingness to use ≥ 1 MBC method.
Overall, 72% of participants (n = 187; mean age, 29) were very willing to use ≥ 1 MBC method although support for individual methods ranged widely from 62% (pill) to 24% (vas occlusion). In bivariate analysis of sociodemographic and health characteristics, few demonstrated associations with MBC willingness. In a multivariable model, willingness was independently related to age (30-39 vs. 18-29 years old, aPR = 1.24, 95% CI 1.04-1.48) and having ever been tested for HIV (aPR = 1.27, 95% CI 1.07-1.51). Willingness to tolerate side effects was < 10% for most items. The most commonly endorsed barriers to MBC use were high cost (77%) and side effects (66%).
Enthusiasm for MBC was high but waned in the context of potential side effects and barriers. Additional research on MBC attitudes in socioeconomically and culturally diverse populations worldwide is sorely needed.
全球对男性避孕新方法（MBC）的需求很高。然而，关于男性对特定方法的态度及其决定因素的当代证据很少。
在美国中西部的一次大型社区活动中，对18至45岁有近期女性性伴侣史的未绝育顺性别男性进行了调查。我们通过方法（凝胶、药丸、注射、植入和输精管阻塞）、潜在副作用和潜在障碍来研究参与者使用MBC意愿的差异。我们估计了参与者特征与使用≥1种MBC方法意愿之间关联的粗患病率和调整患病率（aPRs）。
总体而言，72%的参与者（n = 187；平均年龄29岁）非常愿意使用≥1种MBC方法，尽管对个别方法的支持率差异很大，从62%（药丸）到24%（输精管阻塞）。在社会人口统计学和健康特征的双变量分析中，很少有因素与使用MBC的意愿相关。在多变量模型中，意愿与年龄（30 - 39岁与18 - 29岁，aPR = 1.24，95% CI 1.04 - 1.48）和曾接受过HIV检测（aPR = 1.27，95% CI 1.07 - 1.51）独立相关。对于大多数项目，愿意忍受副作用的比例<10%。使用MBC最常被认可的障碍是成本高（77%）和副作用（66%）。
对MBC的热情很高，但在潜在副作用和障碍的背景下有所下降。迫切需要在全球社会经济和文化多样的人群中对MBC态度进行更多研究。
