Efecto in vitro del pentóxido de vanadio (V2O5) sobre la calidad espermática

Vanadium is a heavy metal considered an environmental pollutant product of anthropogenic manipulation; it infl uences the masculine reproductive potential, especially the sperm motility. This research had the objective of determining the effect of vanadium pentoxide on sperm quality in vitro. Spermatozoa were incubated for 24 hours under 0, 1 and 2 ppm V 2 O 5 concentrations, and sperm motility and vitality, membrane integrity, acrosome reaction and sperm chromatin integrity were assessed. V 2 O 5 altered sperm motility in a signifi cant way, specifi cally moderated (p 0.05). Similarly, we did not observe nuclear material alterations. Vanadium is able to alter sperm motility and viability without inducing changes on membrane and chromatin integrity.
