Aim:  Uterine transplantation is developing into a clinical treatment for uterine factor infertility. An animal model with a similar uterus size and vessels to humans and with pregnancy extending over several months would be beneficial for research on uterine transplantation. The aim of this study was to develop and evaluate autotransplantation of the sheep uterus to an orthotopic position in the pelvis. 

Uterine transplantation: one human case followed by a decade of experimental research in animal models

The results of these specific studies on surgical technique, ischaemia‐reperfusion injury, immunosuppression and fertility are discussed.

To see if: (i) a large vessel aortocaval vascular patch technique may bring about long‐term graft survival after allogeneic uterine transplantation (UTn) in a rabbit model; and (ii) fertility can be

First report on fertility after allogeneic uterus transplantation

For the first time pregnancy after allogeneic uterus transplantation is described, as a proof of concept of uterine function in a transplanted uterus in a standardized animal model (rat) under immunosuppression.

The development of an extended normothermic ex vivo reperfusion model of the sheep uterus to evaluate organ quality after cold ischemia in relation to uterus transplantation

This work aimed to develop an ex vivo sheep uterus reperfusion platform that mimics the reperfusions situation so that initial assessments and comparisons can be performed without the need for costly and labor‐intensive in vivo transplantation experiments.

Uterus Transplantation: An Update and Preparations for Introduction in India

The clinical field of composite tissue transplantation now also includes uterus transplantation (UTx), a new type of quality-oflife enhancing and in this case also life-giving transplantation. The

Uterus transplantation: How far away from human trials?

An overview of the animal research that has been conducted in preparation for human uterus transplantation is given and it is predicted that uterus transplants will be introduced as an experimental procedure in the human within a few years.

Achieving uterine auto‐transplantation in a sheep model using iliac vessel anastomosis: a short‐term viability study

To investigate, develop and evaluate anatomical, surgical and anastomotic aspects necessary for a successful uterine transplant in a large‐animal model.

Uterus transplantation: Toward clinical application in Japan

In recent years, uterus transplantation (UTx) has been applied as the treatment for patients with uterine factor infertility worldwide. Thus, the clinical application of UTx in Japan should be

Uterus transplantation in the baboon: methodology and long-term function after auto-transplantation.

This study demonstrates the feasibility of UTx by vascular anastomosis in a non-human primate species by developing surgical techniques for uterus retrieval and transplantation in the baboon.



Auto‐transplantation of the uterus in the domestic pig (Sus scrofa): Surgical technique and early reperfusion events

Aim:  To develop a method for auto‐transplantation of the uterus in the pig and to evaluate the early reperfusion events after short‐term cold ischemia.

Transplantation of the uterus

Successful uterine transplantation in the mouse: pregnancy and post-natal development of offspring.

These observations document the capacity of a transplanted uterus to harbour pregnancies to term, and reveal that offspring from a transplants uterus develop to normal fertile adults.

Heterotopic uterine transplantation by vascular anastomosis in the mouse.

An undisturbed function of the transplanted uterus horn was finally demonstrated by its ability to implant inserted blastocysts and to carry pregnancy with fetal weight being similar to that of fetuses in the native uterus and controls.

Rejection patterns in allogeneic uterus transplantation in the mouse.

A murine model to study rejection of allogeneic uterus transplants was characterized and signs of rejection were seen from day 2 to day 5 and severe rejection was seen from days 10 to day 15, useful in future studies on immunosuppressants in this model.

Short-term ischaemic storage of human uterine myometrium--basic studies towards uterine transplantation.

The results show that human uterine myometrial tissue is resistant towards cold ischaemia for at least 6 h if stored in UW and PER solutions.

Functional assessment of the autotransplanted uterus and ovary in the ewe

Ewes with utero-ovarian autotransplants showed regular oestrous cycles and had normal luteal phases, however, ewes in this series failed to show oestrus due to maintenance of the corpus luteum as indicated by the fact that the concentration of progesterone remained elevated for up to 220 days.

Pregnancy after transplantation of cryopreserved ovarian tissue in a patient with ovarian failure after chemotherapy.
