Investigating media that support red wolf () sperm viability and capacitation .

Unlabelled: The red wolf is a critically endangered canid, with ~250 and ~20 individuals in the and reintroduced wild populations, respectively. Assisted reproductive technologies such as sperm cryopreservation and fertilization therefore represent critically-needed tools to manage these populations. However, the motility of post-thaw red wolf sperm rapidly declines during incubation, hindering the ability to develop these technologies.
