Follicular right shift: Xenografting queens' ovarian tissue into severe combined imunnodeficiency mice and its responses to exogenous gonadotropin.

Ovarian xenografting is an auxiliary reproductive technique that allows the conservation of germplasm of high-value livestock and endangered species. The use of exogenous gonadotropins assists in developing xenografted tissues and obtaining viable follicles for in vitro embryo production; however, this use has not been reported in the xenografting of cats' (Felis catus) ovaries with C57BL/6 female SCID mice (Mus musculus) as recipients. Therefore, the aim of this study was to evaluate the responses of queens' ovaries to eCG when grafted into C57BL/6 female SCID mice.
