The recent successful births following live donor uterus transplantation are proof-of-concept that absolute uterine factor infertility is a treatable condition which affects several hundred thousand infertile women world-wide due to a dysfunctional uterus. This strategy also provides an alternative to gestational surrogate motherhood which is not practiced in most countries due to ethical, religious or legal reasons. The live donor surgery involved in uterus transplantation takes more than 10 h and is then followed by years of immunosuppressive medication to prevent uterine rejection. Immunosuppression is associated with significant adverse side effects, including nephrotoxicity, increased risk of serious infections, and diabetes. Thus, the development of alternative approaches to treat absolute uterine factor infertility would be desirable. This review discusses tissue engineering principles in general, but also details strategies on how to create a bioengineered uterus that could be used for transplantation, without risky donor surgery and any need for immunosuppression. We discuss scaffolds derived from decellularized organs/tissues which may be recellularized using various types of autologous somatic/stem cells, in particular for uterine tissue engineering. It further highlights the hurdles that lay ahead in developing an alternative to an allogeneic source for uterus transplantation.

Introduction: Uterine transplantation is currently intended for women with absolute uterine infertility. Since proof of the concept in 2014, many countries have started research programs and clinical activities. However, access to uterine transplantation remains limited given that only a few hundred transplants have been described worldwide compared with the 1.

Transplantation of decellularized uterus tissue showed promise in supporting regeneration following uterine injury in animal models, suggesting an alternative to complete uterus transplantation for uterine factor infertility treatment. However, most animal studies utilized small grafts, limiting their clinical relevance. Hence, we used larger grafts (20 × 10 mm), equivalent to nearly one uterine horn in rats, to better evaluate the bioengineering challenges associated with structural support, revascularization, and tissue regeneration.

Introduction: Since 2017, women with absolute uterine infertility due to Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome have been eligible to participate in a uterine transplantation clinical trial conducted by Foch Hospital in France. The aim of this study is to assess the psychological state of potential candidates, including recipients, their partners, and their living-related donors.
Material And Methods: Sixteen potential uterus transplant candidates, including recipients, partners, and living-related donors, participated in the study.

Background: Intrauterine adhesion (IUA), resulting from uterine trauma, is one of the major causes of female infertility. Previous studies have demonstrated that endometrial mesenchymal stem cells (eMSC) have therapeutic effects on IUA through cellular secretions. It is particularly true for most of the pre-clinical experiments performed on multiple animal models, as human-derived eMSC cannot maintain long-term engraftment in animals.
