P-60: The Comparison of Semen Parameters in Smokers and Non Smokers Who Refer to Infertility Clinic

Background: Facing infertility put too much emotional stress and physical burden on infertile couples that make it difficult to deal with. According to this fact that infertility in some men appears with specified disorder but in most cases there is no clear cause for male infertility which determine the special attention to lifestyle and environmental factors. In this study the effects of smoking on semen parameters in infertile couples are studied. Materials and Methods: This retrospective descriptive study on 1263 men, 948 non smokers and 315 smokers (279 light smokers and 36 heavy smokers) were done. All women who don’t have the factors affecting sperm except cigarette were entered into the study. Results: The result showed that the prevalence of smoking in the population studied was 24.9% which was only2.85% of them heavy smokers. Greatest impairment observed in the study population was impaired sperm motility which was 32.4% of the total population. Abundance count of abnormal sperm among smokers was 16.19% and among non-smokers was 10.4% (p<0.0001) abundance of abnormal sperm motility among smokers was 42% and among non-smokers was 29.2% (p<0.0001), morphology abundance of abnor mal sperm among smokers was 6.9% and among nonsmokers was 0.73% (p<0.0001). The age distribution in sperm count changes has shown a significant association (p<0.0001). Conclusion: In this study, smoking had an effect on every three factors, sperm number, motility and morphology. Greatest impact was on the sperm morphology and sperm motility disorders are the most common disorder in this study that could be a factor in semen quality reduction. Only light smoker didn’t show significant correlation with sperm count but sperm motility and morphology was dependent to light smoker as well and age changes only affected the sperm count.
