The Effect of Temperature on Sperm Motility and Viability

Abstract

Sperm motility is a key factor in permitting us to decide semen quality and capacity to fertilize. Motility in semen is for the most part constrained by K+ in salmonids, and presumably additionally in sturgeons, and by osmotic pressure in other freshwater and seawater fish species; however, different elements, for example, combination of encircling metabolites and particles (Ca2+, Mg2+, and so on.), pH and temperature likewise impact motility attributes. In the chapter, the author has fundamentally surveyed and abridged the impacts of temperature on the motility of spermatozoa in some fish species (salmonids, cyprinids, and sturgeons) and of humans also. DSper fluxes are initiated by warm temperatures and intercedecation conductance, which shares a pharmacological profile suggestive of TRPV4. Together, these outcomes recommend that TRPV4 actuation triggers early membrane depolarization, encouraging both CatSper and Hv1 gating and, therefore, sperm hyperactivation.
