Evaluation of cryopreserved ovarian tissue from prepubertal patients after long-term xenografting and exogenous stimulation

This is the first description of transplantation of human cryopreserved prepubertal ovarian tissue to mice, demonstrating that a very high number of follicles survive after transplantation and a large pool of primordial follicles remains dormant. Growing follicles were observed, proving the responsiveness of prepubertal ovarian tissue to gonadotropins.
