Forty-three nonsmokers attending an infertility clinic reported their degree of passive exposure to environmental tobacco smoke (ETS) and provided samples of blood and seminal plasma. Levels of nicotine and cotinine in biological fluid were evaluated by a radioimmunoassay. The data indicate that exposure to ETS results in measurable nicotine and cotinine levels in seminal plasma. Seminal plasma cotinine concentration also shows a significant positive correlation with degree of reported exposure.
43名前往不孕不育诊所就诊的非吸烟者报告了他们被动接触环境烟草烟雾（ETS）的程度，并提供了血液和精浆样本。通过放射免疫分析法评估生物体液中尼古丁和可替宁的水平。数据表明，接触ETS会导致精浆中尼古丁和可替宁水平可测。精浆可替宁浓度也与报告的接触程度呈显著正相关。
