Objectives: (1) To describe sperm kinetics in semen samples in infertile couples; (2) Evaluation of the factors related to sperm kinetics. Subjects and methods: Descriptive study cross-sectional 50 semen samples in the husband of the infertile couple. Sperm motility and kinetics were evaluated using computer‐aided sperm analysis Hamilton Thorne IVOS II. Results: The mean values ​​of VCL, VSL, VAP, ALH in the normal morphological group were higher than in the abnormal morphology group (p < 0.05). There were the positive correlations between VCL (r = 0.373, p = 0.008), VSL (r = 0.343, p = 0.015), VAP (r = 0.381, p = 0.006), ALH (r = 0.311, p = 0.028) with normal sperm morphology; and negative correlation between VCL (r = -0.286, p = 0.044) with head abnormality. The normal morphological in the group with drinking alcohol was lower than in the group that did not drink, (p = 0.027). The neck-tail abnormality in the drinking group was higher than in the non-drinking group (p = 0.124); The neck-tail abnormality in the smoker group was higher than in the non-smoker group (p = 0.001). Sperm kinetics parameters (VCL, VSL, VAP, ALH, LIN, STR) recorded lower than in the drinking and smoker group, (p > 0.05). Conclusion: Motility and kinetics are related to sperm morphology. Sperm kinetics combines semen parameters to evaluate male fertility more totally. Key words: sperm, semen parameters, sperm kinetics, computer‐aided sperm analysis
