Be careful, semen diluents influence motility
Professor Aurich, at Centre for Artificial Insemination and Embryo
Transfer, University of Veterinary Medicine (Vienna) published results of different diluents' impact on dog semen motility. They found that TRIS and PROST were the media with the lowest influences on parameters of canine semen, and are therefore recommendable for the use in SpermVision. Due to the high concentration of fresh canine semen, dilution of the main fraction is usually required for further analysis in automated semen analyzers. So watch out what diluents do you choose to control semen quality.
