• Fertility preservation methods for prepubertal women about to undergo gonadotoxic chemo and/or radiation therapy are limited. Therefore, the aim of this study was to investigate the feasibility to develop an alternative fertility preservation method based on an ex vivo perfusion platform for whole ewe ovaries. Thirteen ewe ovaries were divided into two groups (group 1 and 2) that were perfused in a bioreactor for up to 7days. Group 1 (n =3) were stimulated with human menopausal gonadotropin (hMG) administered in single daily dose, while group 2 (n =10) were stimulated continuously for 24h. The perfused ovaries in group 1 showed no significant differences in follicular density, sub-follicular morphology and oocyte quality after ischaemia and after ex vivo perfusion compared with non-perfused control ovaries. The perfused ovaries in group 2 showed a significant decrease in the follicular reserve and oocyte quality compared with the control group. In total, 16 GV-MI oocytes were retrieved from both groups. This study describes for the first time the ex vivo maintenance of viable follicles of ewe ovaries with oocyte integrity and the retrieval of oocytes after ex vivo hormonal perfusion with two different protocols for up to 7days.
