Objective: To assess the effects of smoking on total sperm count, progressive sperm motility and sperm morphology among couples attending an infertility clinic. Methods: A total of 223 sperm samples (126 smokers and 97 nonsmokers) from men attending an infertility clinic for routine infertility workup were compared on the basis of standard semen analysis. Results: Cigarette smoking is negatively correlated with progressive motile sperm count (r = -0.1464, p = 0.042), but not with sperm concentration (p = 0.961), total motile sperm count (p = 0.890) and sperm morphology (p = 0.838). Furthermore, packages/year (cumulative dose of cigarettes) did not correlate with any of the sperm parameters including sperm density (p = 0.976), total (p = 0.559) and progressive (p = 0.406) motile sperm count and sperm morphology (p = 0.449). Conclusions: Although the effect of smoking on male infertility remains inconclusive, smoking had an adverse effect on the progressive sperm motility, irrespective of total amount of cigarettes smoked per day.
