Semen Collection, Cryopreservation and Artificial Insemination in Dogs

Today, the methods of artificial insemination, that have recently become a biotechnological phenomenon, have being used in dogs especially for those partners that are largely unable to mate because of differences in their body sizes. Artificial insemination is likely only by diluting the semen collected in order to protect it from the environmental conditions, by using some short- and long-term preservation methods and by transferring it into the females with proper techniques. Therefore, in this brief review, some data about the approach to the male at the time of semen collection, as well as the collection itself (digital manipulation, conic plastic rubber along with hand massage, and electrical stimulations (the electro-ejeculator)), dilution (Tes, Bes, Hepes, Pipes, Tris, Tes/Tris and commercial extenders, at 1:1-1:5 dilution rate), short (at +4 oC) - and long-term (in ampoule, pellet and straw) frozen storage (within liquid nitrogen, at -196 oC) of semen and artificial insemination methods (intravaginal catheter, Norwegian intrauterine catheter, endoscopic intrauterine and surgical intrauterine technique)) are given in dogs.
