Since the mammalian spermatozoa became capable of motion, during the epididymal
transit, the spermatozoon swims in a liquid medium and it is completely dependent on the
environmental conditions. Some reports have suggested an influence of pH on sperm kinetic
characteristics, but no study has objectively described how motility changes in a different
environmental pH. In this study, we evaluated the effect of different environmental pHs (5.5,
6, 6.5, 7, 7.5, 8, and 8.5) on kinetic parameters, sperm viability, mitochondrial activity, and …
