Criopreservação de sêmen de epidídimo de garanhões

It is a fact that Brasil has a featured position in the equine market due to the size and the high quality of its squad. To keep the competitivity, the reproduction biotechnologies have a big and important role. The cryopreservation of stallion semen, for example, generates innumerous advantages, which includes: larger number of obtained doses, storing genetic material for undetermined time, using the semen of a good stallion even after its dead or any other event that makes both semen collection and mating impossible, etc. In this context, the cryopreservation of epididymal sperm, has been seen as a promising technique in equine reproduction. The epididymal cauda has a significant quantity of fertile spermatozoa and this ensures a huge store of cells in cases of unexpected accidents, which can early interrupt with the reproductive life of a stallion. Lots of studies are being developed using the cryopreservation of stallion epididymal sperm. These studies permit the propagation of high quality genetic material and make possible for the stallion owner to opt for a final semen collect in unexpected circumstances
