The cryopreservation of murine ovarian tissue and its transplantation can be a promising technique for the preservation of fertility and an alternative for the future reconstitution of scientific valuable strains of mice. Accordingly, the aim of this study was to describe the entire surgical procedure for ovariectomy and dorsal subcutaneous autotransplantation in mice, and also some data about the efficiency of this procedure. Female C57Bl/6J mice (n = 18) were anaesthetised and bilaterally ovariectomized. After surgery, ovaries were autotransplanted in small subcutaneous pouches in the dorsal region of the forelimbs. The animals were inspected daily and, 23 days after transplantation, euthanasia and recovery of ovarian tissues were performed. Postoperative recovery, oestrous cyclicity, and folliculogenesis progression were evaluated. At 23 days after transplantation, the recovery of the ovaries was feasible, all classes (primordial to antral) of follicles were observed. Additionally, satisfactory efficiency rates were obtained, with 100% of anaesthesia survival rate, survival, graft recovery, folliculogenesis progression and oestrous cyclicity. In general, this short article describes ovarian ectopic autologous transplantation as an effective technique for maintaining rodent oogenesis and endocrine ovarian function. Even more broadly, we can still assume that the application of this technique may reduce the number of breeding matrices and experimental animals in the near future. |
