Provider Knowledge and Support of Uterus Transplantation: Surveying Multidisciplinary Team Members

Exploring Divergent Views: A Comparative Study of Uterus Transplantation Perceptions among Transplant and Obstetrics/Gynecology Providers

Background: Uterus transplantation (UTx) provides women with absolute uterine-factor infertility (AUFI) the opportunity to carry their own pregnancy and deliver a child. There are multiple ethical and medical concerns associated with UTx. Since the last survey of US provider perceptions of UTx in 2018, there have been additional reports of successful transplantations and pregnancies. This study aimed to identify the perception of UTx among providers involved in the diagnosis of AUFI and on the transplant team to help us understand knowledge gaps and determine what barriers must be overcome for UTx to be used in general clinical practice. Methods: We administered REDCap surveys to conference attendees at the 2023 American College of Obstetricians and Gynecologists (ACOG) conference and 2023 American Transplant Congress (ATC). Participants were recruited by medical student volunteers. Results: Two hundred ACOG and ATC attendees completed the survey. Medical concerns related to UTx were reported by 42% of providers from ACOG compared to 22% of providers from ATC. Overall, 76% of participants agreed that UTx should be an option for patients with congenital AUFI. Lastly, 68% of participants agreed that the procedure should be presented as an option for transgender women. Conclusions: This study further elucidates the perception of UTx among obstetricians/gynecologists and transplant physicians. We found greater support for the procedure than in previous studies. This study also demonstrates provider support for presenting this procedure as an option for transgender women.

Who should provide the uterus? The ethics of live donor recruitment for uterus transplantation

Uterus transplantation (UTx) is an experimental surgery likely to face the issue of organ shortage. In my article, I explore how this issue might be addressed by changing the prevailing practices around live uterus donor recruitment. Currently, women with children - often the mothers of recipients - tend to be overrepresented as donors. Yet, other potentially eligible groups who may have an interest in providing their uterus - such as transgender men, or cisgender women who do not wish to gestate or to have children - tend to be excluded as potential donors. Moving forward, I recommend that donor inclusion criteria for UTx be broadened to be more inclusive of these latter groups.

Awareness and Interest in Uterus Transplantation over Time: Analysis of Those Seeking Surgical Correction for Uterine-Factor Infertility in the US

This study describes the characteristics of women who contacted an active program performing uterus transplantation (UTx) in the US, expressing interest in becoming a uterus transplant recipient or a living donor. Basic demographic and self-reported clinical information was collected from women who contacted any of the three US UTx programs from 2015 to July 2022. The three centers received 5194 inquiries about becoming a UTx recipient during the study timeframe. Among those reporting a cause of infertility, almost all of the reports (4066/4331, 94%) were absence of a uterus, either congenitally (794/4066, 20%) or secondary to hysterectomy (3272/4066, 80%). The mean age was 34 years, and 49% (2545/5194) had at least one child at the time of application. The two centers using living donors received 2217 inquiries about becoming living donors. The mean age was 34 years, and 60% (1330/2217) had given birth to ≥1 child. While most of the UTx clinical trial evidence has focused on young women with congenital absence of the uterus, these results show interest from a much broader patient population in terms of age, cause of infertility, and parity. These results raise questions about whether and to what extent the indications and eligibility criteria for UTx should be expanded as the procedure transitions from the experimental phase to being offered as a clinical treatment.

Uterus transplantation in a sheep model: novel surgical technique with long-term survival and uterus vitality. First case series in Argentina

OBJECTIVE

To develop a sheep autologous uterus transplantation (UT) program with an innovative surgical technique and assess long term uterus vitality and animal survival.

METHODS

A novel surgical technique consisting of the procurement of the complete uterus and the two ovaries, back table vascular reconstruction, and subsequent implantation in the same animal, performing only two arterial and two venous anastomoses.

RESULTS

Four autologous transplantations were performed; anesthesia and surgery were well tolerated by all the animals without complications. Direct observation and Doppler US performed a week after UT and laparoscopy performed three months later confirmed uterus vitality. All animals were alive more than a year after transplantation.

CONCLUSIONS

Our study was the first to describe a novel surgical technique for sheep uterus autologous transplantation in Latin America, showing long-term survival and uterus vitality.

Uterine Transplantation: Evolving Data, Success, and Clinical Importance

Uterine transplantation is an evolving procedure to allow for childbearing in paitents with absolute uterine factor infertility. The objective of this study was to review the existing literature using a comprehensive PubMed literature search. A systematic medical subheadings search strategy was used with the terms "uterus transplant" and "uterine transplantation". Of the 75 full-text articles assessed for eligibility, 68 were included in the qualitative synthesis. Of these, 9 were included in the meta-analysis on living donor uterine transplant, 5 on deceased donor uterine transplant, and 6 case reports of single uterine transplants. In conclusion, uterus transplant is a nascent field undergoing a rapid rate of evolution as programs mature their data and increase the number of procedures performed. The most recent publications and advances are thus summarized in this article to capture the most up-to-date information.
