We investigated the incidence of cigarette smoking in a sample of patients and compared these figures with estimates of smoking among males in the general population. Among 178 impotent patients the number of current smokers (58.4%) and current ex-smokers combined (81%) was significantly higher than would be expected among males in the general population. In each age group, and at all levels of tobacco use, impotent patients smoked more than would be expected from population estimates. Smoking and nonsmoking impotent patients did not differ in terms of their hormonal profile; however, mean penile blood pressure (PBI) was lower among patients who smoked than among those who did not. A significantly higher proportion (20.9%) of impotent patients with a history of smoking showed abnormally low PBI compared with nonsmoking patients (8.8%). This study adds to preliminary evidence that smoking may be a significant risk factor in impotence, and its effects are evident in the small vasculature.
我们调查了一组患者中的吸烟发生率，并将这些数据与普通人群中男性的吸烟估计数进行了比较。在178名阳痿患者中，当前吸烟者（58.4%）和当前已戒烟者（81%）的总和显著高于普通人群中男性的预期比例。在每个年龄组以及所有烟草使用水平上，阳痿患者的吸烟量均高于根据人群估计数所预期的水平。吸烟和不吸烟的阳痿患者在激素水平方面并无差异；然而，吸烟患者的平均阴茎血压（PBI）低于不吸烟患者。与不吸烟患者（8.8%）相比，有吸烟史的阳痿患者中PBI异常低的比例显著更高（20.9%）。这项研究进一步证明吸烟可能是阳痿的一个重要风险因素，其影响在小血管系统中很明显。
