Impact of Cigarette Smoking on Sperm Parameters of Infertile Men in Center of Algiers (Capital of Algeria)

Abstract

Background : Cigarette smoking has negative effects on male fertility. Toxins from tobacco smoking can potentially affect sperm development and function, with a negative effect on semen parameters. In fact, the components of cigarette smoke pass through the blood-testis barrier and thus induce an alteration of sperm parameters and nucleus quality of the spermatozoa. The aim is to determine a diffence between tobbaco and no tobbaco patient and semen parameters. This article aimed to assess the relationship between smoking and male infertility. Subject and Methods : this is retrospective study focused on the effects of smoking on semen analyses.  377 men (165 non-smokers, 212  smokers) with infertility for at least 1 year were evaluated between  Mars  and  November 2018, in center of algiers (capital of Algeria). Sperm characteristics (concentration, motility, morphology, and volume) were detemined. Results: Sperm concentration, percentage motility and morphology were significantly lower in an infertile Smokers group than the infertile Nonsmokers group. We also observed that the infertility duration were significantly increased (p<0.05) in accordance with the age in an infertile Smokers group.  Our study shows that cigarette smoking is associated with reduced sperm count and motility. Conclusions: Our results suggest that cigarette smoking has an overall negative effect on semen parameters. Our study suggests that men should be advised to abstain from smoking in order to improve reproductive outcomes. Keywords: smoking, semen, male infertility, sperm, humans
