title: Effect of tobacco consumption on semen quality of a population of hypofertile males.
abstract: Effect of tobacco use (by chewing or smoking) on semen quality has been seen. Semen analysis of 119 tobacco chewers and 219 smokers was compared with those of 288 control patients. Some decrease in the ejaculate volume, sperm density, and total count was observed in tobacco users, but it was statistically insignificant. No difference was found in other parameters, like motility and morphology. It is concluded that tobacco use by chewing or smoking is not associated with impaired semen quality in males selected from an idiopathically hypofertile population.
