Abstract
We observed the influences of low-temperature storage of the feline epididymis on the epididymal semen qualities and those after cryopreservation to identify the duration of low-temperature storage of the epididymis. After excision, the feline epididymis was stored at 4℃ for 0–72 hr, followed by epididymal sperm collection. When sperm refrigerated cauda epididymis were frozen and thawed, there was no significant difference in sperm motility between the 0- and 24-hr low-temperature storage groups, but sperm motility was significantly decreased in the 48-hr storage group. The above findings suggested that low-temperature storage of the epididymis until 24 hr is useful of frozen sperm collected from the feline cauda epididymis.
