Abstract: Objective To explore the optimal conditions for Cauda epididymis transport under room temperature and eliminate the effect of medium on the transport of cauda epididymides at room temperature. Methods The transport methods of cauda epididymides were modified in this study and the sperm motilities, fertility and developmental abilities of IVF embryos after transportation at room temperatures or 4~8℃ in 20 μl of medium M2 or medium-free tube were compared. Results Under room temperatures, delivery of cauda epididymides without medium was significantly superior to with medium, but was inferior to 20 μl M2 medium under 4~8℃. Conclusion The modified medium-free system was beneficial to room temperature transportation of cauda epididymides and maybe eliminate the side effects of medium on spermatozoa, and the delivery of cauda epididymides under room temperature was useful for transporting some valuable strains between mouse banks and research facilities.
