MENDEZ, Yoeli; BAEZ, Francisco  e  PATRICIA, Villamediana. In vitro effect of vanadium pentoxide (V₂O₅) on sperm quality. Perinatol. Reprod. Hum. [online]. 2014, vol.28, n.4, pp.187-192. ISSN 2524-1710.

Vanadium is a heavy metal considered an environmental pollutant product of anthropogenic manipulation; it influences 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 V₂O₅ concentrations, and sperm motility and vitality, membrane integrity, acrosome reaction and sperm chromatin integrity were assessed. V₂O₅ altered sperm motility in a significant way, specifically moderated (p < 0.01), slow (p = 0.01), and non motile (p < 0.01) sperm motility patterns. The groups treated with V₂O₅ had a major percentage of live spermatozoa than the control group (p < 0.01). Membrane integrity and acrosome reaction were not affected by human sperm exposition to V₂O₅ (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.
