Objective: To report two cases of orthotopic transplantation of fresh ovarian tissue.
Setting: Academic hospital.
Patient(s): Two patients with severe endometriosis, who underwent left oophorectomy for recurrent endometriosis.
Intervention(s): Ovarian cortex was reimplanted in the heterolateral orthotopic site.
Result(s): Biopsies of the grafted tissue were taken 3 months after reimplantation. Viable primordial follicles were found. The presence of a neovascular capillary network was demonstrated.
Conclusion(s): Reimplantation of fresh ovarian cortex allows the survival of primordial follicles and may represent an alternative method for the preservation of ovarian cortex when oophorectomy is mandatory.
