Establishment of sperm cryopreservation and in vitro fertilisation protocols for rats.

ABSTRACT: Recently, genome-editing tools have come into common use in the field of rat research, and consequently, many genetically modified rat strains have been preserved and archived as frozen embryos. Although there have been many reports published on the topic of rat sperm cryopreservation, no report has yet provided satisfactory and acceptable protocols for the cryopreservation of rat sperm. In this study, we developed methods for both the cryopreservation of transgenic rat sperm and in vitro fertilisation using frozen sperm, which yielded high fertilisation rates.
