Cover Story: Successful artificial reproductive technologies (ARTs) are paramount for conservation programs, establishing biobanks for threatened species. While the use of ARTs in wildlife species has advanced in recent years, without efficient collection and cryopreservation of sperm, ARTs are limited. The highly viscous nature of the rhino ejaculate reduces the amount of usable semen, making the high-risk procedure of semen collection inefficient. Using papain, we reduced the viscosity of ejaculates, increased the yield of sperm collected, and improved sperm motility post-cryopreservation, without any detriment to membrane characteristics. This work offers a new protocol to improve cryopreservation of rhino semen, contributing toward improved fertility outcomes for the rhino and other threatened species.
