چکیده

I would like to comment on the article by Dr. Saleh and colleagues, which adds new information to the growing body of evidence about the negative effects of smoking on reproductive health (1). In 1998, two consecutive papers were published by our group dealing with the effects of smoking on human sperm viability via the seminal plasma factor and at the ultrastructural level of the sperm tail axoneme (2, 3). In one of the studies (2), spermatozoa fro nonsmokers were exposed to seminal plasma from smokers ( 30 cigarettes/d for at least 3 years), and spermatozoa from smokers to seminal plasma from nonsmokers. Our findings indicated that exposure of nonsmoker spermatozoa to seminal plasma from smokers significantly reduced sperm motility and membrane functional integrity. The negative effects on sperm viability increased during shortand long-term incubation in smokers seminal plasma. On the other hand, incubation of smokers’ spermatozoa with seminal plasma from nonsmokers improved viability. Thus, the negative effect of smokers’ seminal plasma seems to be reversible to some extent, as seen when reconstituting spermatozoa with nonsmoker seminal plasma or by washing with culture media.

A never-ending story

Today we won’t talk about dragons that take you for a walk if you get on its hump. Nor we’ll talk about men with feet on their heads or any other creature from the delusional mind of Michael Ende.

And why are there s...
