| Research Abstract |
Preservation of biological resources became more important, but no method for embryo/sperm cryopreservation is well established in Syrian hamsters, Mongolian gerbils, or guinea pigs, which are often used in laboratories. In this study, I tried to establish a method for preservation of these species by ovarian cryopreservation. I obtained pups by orthotopic transfers of vitrified ovaries in Syrian hamsters, but not in gerbils or guinea pigs. Graft immunity and operating procedures need to be considered for ovarian transfers in these two species.
