Methods: Semen analysis was performed in 112 patients following the laboratory manual for the examination and processing of human semen of the World Health Organization (WHO), fifth edition. Sperm were separated by swim up technique and sperm parameters were reevaluated. Relation between basal sperm morphology and sperm parameters after swim up were evaluated by correlation coefficient analysis. Results: Means of basal parameters were above lower limits established by the WHO. After swim up, the average of sperm recovery, total motility and progressive motility were 8.89 ± 0.86, 91.74 ± 0.97, 97.41 ± 0.66 respectively. Sperm parameters after swim up showed an apparently lower concentration of sperm recovered when normal sperm morphology is lower in basal samples; however, these results were not statistically significant. Conclusion: There is no correlation between basal sperm morphology and quality sperm recovered after swim up, despite an apparently lower concentration of sperm after sperm separation  is observed in patients  with a decreased normal sperm morphology.
