Seminal Plasma and Progressive Motility of Boar Spermatozoa

Abstract
Boar seminal plasma can enhance the progressive motility for washed boar spermatozoa. This effect is dose dependent and the full effect is obtained at 10% of the original seminal plasma concentration. This motility restoration (enhancement) stems not from a change of viscosity in the suspending medium. The component(s) in the seminal plasma responsible for such a restoration is non-nutrient in nature and was found to be heat labile but resistant to storage for two months at -20°C.
