Effect of smoking on concentration, motility and zona-free hamster test on human sperm.
The effect of smoking on sperm concentration, motility, and zona-free hamster egg sperm penetration assay (SPA) was evaluated in 293 smokers of more than 10 cigarettes/day and 382 nonsmokers. Prerequisites for inclusion in the study were sperm concentration of greater than 10 x 10(6)/ml, sperm motility of greater than 30%, and normal morphology of greater than 60%. Although a lower sperm concentration was found in smokers, no significant difference was observed in sperm motility and SPA.
