MENDEZ, Yoeli; BAEZ, Francisco  and  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 0187-5337.

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.

Keywords : Vanadium; human spermatozoa; sperm motility; sperm viability; sperm chromatin integrity.
