The effect of cigarette smoking on conventional semen parameters was studied in voluntary men of reproductive age (n = 190). Special attention was focused on sperm motility and its quantitative and qualitative change in vitro during the observation period. The sperm output war normal in both smokers (n = 54) and non-smokers (n = 110), but semen volume was smaller (p less than 0.03) in heavy smokers (greater than 16 cigarettes/day) than non-smokers. In sperm morphology there was no difference between study groups. The only clear difference between men with different smoking habits was in the percentual change in the sperm motility during 24 hours. At the time of first examination, the sperm motility was better (p less than 0.02) in heavy smokers than those who smoked less than 16 cigarettes per day and the motility decreased more rapidly (p less than 0.007) in heavy smokers than non-smokers. The objectively measured initial mean velocities of the whole sperm population and of the progressive spermatozoa were slightly higher in subgroup of smokers than in non-smokers. The rapid decrease in the survival spermatozoa in smokers may be uneconomical and harmful in respect of fertility.
在190名育龄期自愿参与的男性中研究了吸烟对传统精液参数的影响。特别关注了观察期内精子活力及其在体外的数量和质量变化。吸烟者（n = 54）和非吸烟者（n = 110）的精子产量均正常，但重度吸烟者（每天超过16支香烟）的精液量比非吸烟者少（p < 0.03）。研究组之间精子形态无差异。不同吸烟习惯男性之间唯一明显的差异在于24小时内精子活力的百分比变化。首次检查时，重度吸烟者的精子活力比每天吸烟少于16支的人更好（p < 0.02），且重度吸烟者的精子活力下降比非吸烟者更快（p < 0.007）。吸烟者中存活精子的快速减少在生育方面可能既不经济又有害。
