    Objectives: The aim of this study was to compare the results of an allograft en bloc vagino-utero-ovarian avascular transplant with those of autograft implantation in rats. Materials and Methods: Thirty-four inbred adult virgin female Albino rats (age range, 10 - 12 weeks) were divided into 2 groups: the control group (autograft, n=11) and the study group (en bloc vagino-utero-ovariectomy, n=23). In the study group, the uterus and adnexa and the ovaries of the donor rat were transplanted to the recipient animal. Twenty-five to 30 days after that procedure, all rats were killed, and the samples were assessed histopathologically. No immunosuppressive drugs were used. Results: Ten rats died during the postoperative period. In 16 rats, the transplanted system had survived completely at the conclusion of the study. In each of the study groups, complete survival of the uterus and ovaries was noted in 8 rats (34.8% in the study group and 72.8% in the control group). In all rats except 1, histopathologic examination did not reveal any signs of the classic criteria for tissue rejection reaction. The lack of revascularization, nonspecific signs of inflammation, and the presence of large granular lymphocytes and natural killer cells were reported. Conclusions: Our data indicated that the outcome of both allograft and homograft avascular en bloc transplant of vagino-utero-ovariectomy in rats was successful, and that immunologic rejection did not seem to have an important role in those procedures.
