美国和欧洲有关急性附睾炎发病率与患病率的数据有限,因为该疾病并非国家监测疾病。1977 年,美国估计有 63.4 万名患者寻求附睾炎治疗。[5]Berger RE, Alexander ER, Harnisch JP, et al. Etiology, manifestations and therapy of acute epididymitis: prospective study of 50 cases. J Urol. 1979;121:750-754.http://www.ncbi.nlm.nih.gov/pubmed/379366?tool=bestpractice.com在加拿大开展的一项研究表明,为期 2.5 年时间里,8712 名门诊男性中,0.9% 因附睾炎就诊。[6]Nickel JC, Teichman JM, Gregoire M, et al.

在美国,医疗保健费用与利用项目 (Healthcare Cost and Utilization Project) 数据显示,自 1996 年以来,急性附睾炎患者入院数量几乎没有变化。[8]Chorba T, Tau G, Irwin K. Sexually transmitted diseases. In: Litwin MS, Saigal CS, eds.

Washington, DC: US Government Printing Office; 2007: NIH Publication No. 07-5512:647-695.2001 年的退伍军人事务部门诊数据库显示,每 10 万例门诊就诊人次中有 50 例附睾炎,从 25-34 岁到 55-64 岁的所有年龄组(10 岁 1 组)中,发病率基本类似(从61 / 10 万,到 73 / 10 万)。[8]Chorba T, Tau G, Irwin K.

Washington, DC: US Government Printing Office; 2007: NIH Publication No. 07-5512:647-695.发病率最高的是黑人(87 / 10万)和居住在发达国家的人群(57 /10 万)。
