Introduction Cryopreservation is a process in which cells or whole tissues, sperm cells in this case, are preserved by cooling to sub-zero temperatures. Cryopreservation was carried out with sperm saved from the cauda epididymus and vas deferens of domestic dog testes in this study. Epididymal sperm freezing has had limited success in specific species of cat (Goodrowe and Hay, 1993); pig: (Nagai et al., 1988), and cattle: Watson (1978). In humans, with the use of epididymal sperm, oocytes have been fertilized and subsequent pregnancies have occurred successfully (Friedler et al. 1998). Dog sperm can be stored for several months and be used later with some success in fertility (Marks et al., 1994). Discrepancies between the shape and size of spermatozoa among various canine breeds at different stages of sperm maturation can allow for more water damage during the freeze- thaw process (Watson 2000). The objective of this study was to obtain a successful technique to cryopreserve epididymal dog sperm by modifying current methods that have already proven that they can retain the sperm’s functional ability.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
