Int J Impot Res:在健康男性中,低估阴茎大小影响勃起功能么?

2018-07-01 AlexYang MedSci原创

最近,有研究人员在一个代表性研究的泌尿道检查中,评估了客观的(拉长的)和主观的阴茎大小对勃起功能的影响。研究包括了689名年龄在35岁-70岁的男性。研究人员在多变量模型中利用逻辑回归和线性回归调查了IIEF-5调查问卷、身体检查(阴茎长度、前列腺体积、血压、身体质量指数-BMI)、代谢综合征(MS)、并发症、习惯(性交频率、身体活动、酒精和烟草使用情况)、教育水平、血糖、总睾丸素、雌二醇、PSA

最近,有研究人员在一个代表性研究的泌尿道检查中,评估了客观的(拉长的)和主观的阴茎大小对勃起功能的影响。研究包括了689名年龄在35岁-70岁的男性。研究人员在多变量模型中利用逻辑回归和线性回归调查了IIEF-5调查问卷、身体检查(阴茎长度、前列腺体积、血压、身体质量指数-BMI)、代谢综合征(MS)、并发症、习惯(性交频率、身体活动、酒精和烟草使用情况)、教育水平、血糖、总睾丸素、雌二醇、PSA、血脂和自我认知(射精时间和主观阴茎大小)。

研究发现,客观阴茎平均长度为13.08cm±2.32,67名(9.72%)病人自我认为阴茎较小。76名(11.03%)参与者患有重度勃起功能障碍(ED),75名(10.88%)具有轻度到中等程度的ED,112名(16.25%)具有轻度ED,426名(61.83%)不患有ED。具有统计学显著意义的ED风险因子为自我认为阴茎较小(OR=2.23, 95% CI 1.35-3.69, p=.0017)、性交频率(每周)(OR=0.45, 95% CI 0.38-0.52, p<.0001)、令人满意的射精时间(no vs yes, OR=2.06, 95% CI 1.46-2.92, p<.0001)、并发症((yes vs. no, OR=2.01, 95% CI 1.46-2.76, p<.0001)、年龄大于65岁(OR=2.93, 95% CI 1.53-5.61, p<.0001)、抽烟(yes vs. no, OR=1.41, 95% CI 1.02-1.96, p<.0375)、常规身体运动(no vs. yes, OR=1.59, 95% CI 1.13-2.23, p<.0083)、血清总睾丸素小于200ng/dl(OR=3.48, 95% CI 1.69-7.16, p=0.0009)、血糖大于100mg/dl(OR=1.69, 95% CI 1.18-2.43, p=0.0044)和收缩压大于130mmHg(OR=1.60, 95% CI 1.16-2.19, p=0.0037)。

最后,研究人员指出,除了之前报道的风险因子,患者主观认为的阴茎大小能够负面的影响大约10%健康男性的性生活质量,而客观的阴茎大小对勃起功能的影响不具有显著影响。
