#380 : Clickbait in Uterine Transplant Surgery

Background and Aims: The proliferation of social media platforms has led to the emergence of diverse online communities, presenting unique challenges in terms of patient autonomy and quality of care within the field of uterine transplantation. This research delves into the psychosocial implications of social media communities throughout the uterine transplant patient journey. The absence of standardized guidelines in these virtual spaces presents a novel landscape for healthcare professionals to navigate. This study sheds light on the evolving nature of social media and its impact on the uterine transplant journey, emphasizing the need for healthcare providers to adapt to these unfamiliar territories. Moreover, social media communities introduce additional complexities by increasing the risk of undue influence and coercion on potential donors and transplant candidates. This study will highlight the importance of exploring these themes to ensure the integrity of the transplant process. This study aims to examine the social media discourse surrounding the experiences of both donors and recipients who have undergone uterine transplant surgery. Method: A qualitative research design was employed to observe and reflect on social media posts related to donor and recipient surgeries enrolled in our uterine transplant research study program. Thematic analysis was utilised to identify recurring themes and patterns within the data collected from both recipients and donors. Results: The analysis of social media posts revealed a range of experiences shared by donors and recipients undergoing uterine transplant surgery. Both recipients and donors often expressed mixed feelings associated with their unique transplant experience. Conclusion: Future research and guidelines are needed to navigate the evolving landscape of social media in the uterine transplantation field, safeguarding the well-being of all stakeholders.

Surrogacy in Our Region - How Do We Help Our Patients Who Have No Other Options?

Gestational surrogacy is a well-established fertility treatment with promising treatment success. Gestational surrogacy has multiple dimensions to consider such as medical, psychological, legal, and ethical aspects. Gestational surrogacy is allowed/supported only in some countries which limit access of the couples who require treatment in many countries. Many countries have surrogacy law to regulate gestational surrogacy and to provide legal rights of the intended parents over the birth of their child from the surrogate mother. Surrogacy law also provide protection to the right of the surrogate mother as well. Surrogacy law differs from countries to countries which lead to an increasing trend of cross-border gestational surrogacy treatment toward the countries which allow legal gestational surrogacy or to the country with no law to regulate gestational surrogacy. The intended parents may face legal problems before returning to their countries of origin or when trying to have their children legally recognized in their countries. The intended parents exploring cross-border surrogacy treatment should get legal counsel in their own country to assist with immigration, parentage, and citizenship for the child born through a surrogacy arrangement outside their own country. Due to limitation to gain access to gestational surrogacy for couples in many countries, there is rapidly growing research on the uterus transplantation with reported success on giving birth to healthy children. This could be an alternative to gestational surrogacy for women with uterine factor infertility. However, this also pose some ethical challenge on the uterus donation as organ.

The first successful uterus transplantation in Korea: from a longing wish to become a mother

Miracles of science: Birth after uterus transplantation.

The concept of regaining childbearing ability via uterus transplantation (UTx) motivates many infertile women to pursue giving birth to their own children. This article provides insight into maternal and neonatal outcomes of the procedure globally and facilitates quality of care in related medical fields. The authors searched ISI Web of Science, MEDLINE, non-PubMed-indexed journals, and common search engines to identify peer-review publications and unpublished sources in scientific reference databases. The feasibility of the procedure has been proven with 46 healthy children in 88 procedures so far. Success relies upon dedicated teamwork involving transplantation surgery, obstetrics and reproductive medicine, neonatology, pediatrics, psychology, and bioethics. However, challenges exist owing to donor, recipient, and fetus. Fetal growth in genetically foreign uterine allograft with altered feto-maternal interface and vascular anatomy, immunosuppressive exposure, lack of graft innervation leading to "unable-to-feel" uterine contractions and conception via assisted reproductive technology create notable risks during pregnancy. Significant portion of women are complicated by at least one or more obstetric problems. Preeclampsia, gestational hypertension and diabetes mellitus, elevated kidney indices, and preterm delivery are common complications. UTx has short- and long-term satisfying outcome. Advancements in the post-transplant management would undoubtedly lead this experimental procedure into mainstream clinical practice in the near future. However, both women and children of UTx need special consideration due to prematurity-related neonatal problems and the long-term effects of transplant pregnancy. Notable health risks for the recipient and fetus should be discussed with potential candidates for UTx.

Gender-affirming hysterectomy in the United States: A comparative outcomes analysis and potential implications for uterine transplantation.

Hysterectomy is a gynecological procedure sometimes performed as part of the gender-affirming process for transgender and gender-expansive patients assigned female at birth. Our goal was to compare surgical outcomes between patients undergoing gender-affirming hysterectomy and patients undergoing hysterectomy for benign menstrual disorders. We then explored the implications of gender-affirming hysterectomy for uterine transplantation. We performed a retrospective cohort study using data from the American College of Surgeons National Surgical Quality Improvement Program database from 2009 through 2018. We identified patients undergoing hysterectomy in the United States based on Current Procedural Terminology code. We used the International Classification of Diseases 9 or 10 codes to identify patients with benign menstrual disorders (non-gender-affirming group) and gender dysphoria (gender-affirming group). We compared patient characteristics and surgical complications. Of the 40,742 patients that met inclusion criteria, 526 (1.3%) patients were individuals with gender dysphoria. Compared to patients who underwent hysterectomy for benign menstrual disorders, gender-affirming patients were younger, were healthier, had a lower prevalence of diabetes, and were more likely to undergo surgery in the outpatient setting, with shorter time to discharge. Complication rates were similar between groups. Logistic regression controlling for the American Society of Anesthesiology classification determined the difference of return to the operating room was not statistically significant (OR 1.082; 95% CI, 0.56-2.10; p = 0.816). Gender-affirming hysterectomy has a safety profile similar to hysterectomy performed for benign menstrual disorders. Researchers should further explore the possibility of uterus donation among these patients as they may be suitable candidates.

Perspectives on uterine transplantation

Uterine transplantation is a groundbreaking solution for absolute uterine factor infertility (AUFI), offering hope for motherhood. Advances in transplant surgeries and immunosuppressants have enabled thousands of women to safely become mothers. Approximately 1.5 million women globally suffer from AUFI and thus Uterine transplantation is a significant breakthrough in this arena. So far, 23 babies have been born from transplanted wombs. Uterine transplantation redefines possibilities for motherhood, empowering women's reproductive rights. Ethical considerations persist, but it marks significant progress in reproductive medicine and transplantation science. Further research is needed to evaluate risks and benefits for the future.

Three-year follow-up results of two children born from a transplanted uterus.

To evaluate the 3-year follow-up results of two children delivered at our institution in 2019 from mothers with a transplanted uterus. Observational data on pregnancy outcomes, neonatal course, and growth trajectory in two children born to mothers after uterus transplantation, including 3-year follow-up and neurodevelopmental status assessed using the Bayley Scales of Infant and Toddler Development, third edition (Bayley-III). Both children were born prematurely via uneventful caesarean sections, to mothers with Mayer-Rokitansky-Küster-Hauser syndrome and a transplanted uterus. An acute caesarean section was performed in one mother because of the onset of regular uterine contractions at 34 weeks and 6 days of pregnancy; in the other mother, an elective caesarean section was performed at 36 weeks and 2 days of gestation. The children were born healthy with no congenital malformations. They had an uneventful postnatal course and showed a normal growth trajectory during 3 years of follow-up. The Bayley-III neurodevelopmental scores of both children were within the normal ranges at ages 2 and 3 years. Though pregnancy after uterus transplantation is associated with the risk of premature delivery, no abnormalities were observed in the neonatal course and 3-year follow-up results, including the neurodevelopmental status, of two children born prematurely to mothers with a transplanted uterus. This is the first report on neurodevelopmental outcomes in children born after uterus transplantation. More data on children born after this radical procedure of uterine factor infertility treatment are required to support our promising results.

Estimation of the prevalence of uterine infertility and its different causes in France according to data from a literature review

IntroductionUterine infertility (UI) is defined as the complete absence of a uterus (absolute uterine infertility or AUI) or the presence of a non functional uterus (non-absolute uterine infertility or NAUI). The exact prevalence of uterine infertility is currently unknown. Our aim was to assess the number of French women concerned by Uterine Infertility according to a recent literature review. Materials and methodsWe have previously conducted a systematic review of the literature on UI and its various causes in the world. Based on these study and demographic data of 2022 from INSEE (Institut National de la Statistique et des Études Économiques), we attempted to estimate the number of women under 40 years of age in France affected by potential UI using direct standardization. Results and discussionBased on the estimation from INSEE data, approximately 2066 women of childbearing age would have MRKH syndrome in France, 380 the Androgen Insensitivity Syndrome and 3700 had an haemostasis hysterectomy in France. We did not find data on the prevalence of hysterectomies before the age of 40 in France. For the following pathologies: uterine malformations, radiation uterus, synechiae, myomas and adenomyosis there was a huge amount of missing data, which does not allow us to estimate the number of potentially infertile patients. ConclusionPrevalence of UI is poorly known. UI probably concerns several thousand patients in France. The creation of a UI registry would make enable to assess the number of patients potentially eligible for adoption, uterus transplantation or even surrogacy.

Mayer-Rokitansky-Küster-Hauser syndrome patients’ interest, expectations and demands concerning uterus transplantation

ObjectiveTo better understand patients’ conditions and expectations before starting a uterus transplantation (UTx) program for women suffering from Mayer-Rokitansky-Küster-Hauser syndrome (MRKH syndrome). MethodA web-based survey was conducted among MRKH patients via the French national association network from March to August 2020. The questionnaire comprised twenty-eight questions about their desire for parenthood, their condition's characteristics and previous reconstructive procedures, opinions and knowledge about UTx. ResultsAmong the 148 participants, 88 % reported a desire for parenthood, and 61 % opted for UTx as their first choice to reach this aim. The possibility of bearing a child and having the same genetic heritage were the main motivations. Once informed about the usual course of an UTx protocol, only 13 % of the participants changed their mind and 3 out of 4 of them opted for UT. ConclusionUterus transplantation seems to be the first option to reach motherhood in patients suffering from MRKH syndrome. The development of UTx programs could meet the demands of this already well-informed population.

Long-term Course of Kidney Function in Uterus Transplant Recipients Under Treatment With Tacrolimus and After Transplantectomy: Results of the First Clinical Cohort.

Chronic kidney disease is common after non-renal solid organ transplantation, mainly secondary to calcineurin inhibitors toxicity. Uterus transplantation (UTx) is an innovative treatment for women with absolute uterine factor infertility. UTx is exclusive because it is transient with the absence of lifelong immunosuppression and is performed in young healthy participants. Therefore, UTx provides a unique setting for evaluating the effect of time-limited calcineurin inhibitors treatment on recipients' kidney function. In the first UTx cohort worldwide, we studied kidney function using estimated glomerular filtration rate (eGFR) in 7 women over a median follow-up of 121 (119-126) mo. Median eGFR (mL/min/1.73 m2) of the cohort was 113 at UTx, which declined to 74 during month 3, 71 at months 10-12, 76 at hysterectomy (HE), and 83 at last follow-up. Median duration of tacrolimus exposure was 52 (22-83) mo, and median trough levels (µg/L) were 10 during month 3 and 5.8 at HE. Between UTx and month 3, decline in kidney function was observed in all 7 participants with a median eGFR slope for the whole cohort of -24 mL/min/1.73 m2, which declined further by -4 mL/min/1.73 m2 until months 10-12. Thereafter, eGFR slope improved in 3 participants, remained stable in 3, and worsened in 1 until HE/tacrolimus discontinuation, after which it improved in 2. Eventually, between UTx and last follow-up, 4 of 7 participants had a decline in their eGFR, the median annual eGFR slope being negative at -1.9 mL/min/1.73 m2/y for the whole group. Kidney function declined in all recipients early after UTx followed by a persistent long-term decrease in majority, despite transplantectomy and discontinuation of immunosuppression. Thus, UTx may incur an increased risk of chronic kidney disease even in this young and healthy population, highlighting the importance of close surveillance of kidney function and minimization of tacrolimus exposure.

Reproducibility of Rejection Grading in Uterus Transplantation: A Multicenter Study.

Diagnosis of rejection after uterus transplantation is based on histopathological examination of ectocervical biopsies. Inflammation at the stromal-epithelial interface is the backbone of the histopathological classification proposed by our group in 2017. However, the reproducibility of this grading scheme has not been tested, and it is unclear whether it covers the full morphological spectrum of rejection. We present a multicenter study in which 5 pathologists from 4 uterus transplantation centers performed 2 rounds of grading on 145 and 48 cervical biopsies, respectively. Three of the centers provided biopsies. Additionally, the presence of perivascular stromal inflammation was recorded. During discussions after the first round, further histological lesions (venous endothelial inflammation and apoptosis) were identified for closer evaluation and added to the panel of lesions to score in the second round. All participants completed a questionnaire to explore current practices in handling and reporting uterus transplant biopsies. Cervical biopsies were commonly performed in all centers to monitor rejection. Intraobserver reproducibility of rejection grading (performed by 1 rater) was excellent, whereas interobserver reproducibility was moderate and did not improve in the second round. Reproducibility of perivascular stromal inflammation was moderate but unsatisfactory for venous endothelial inflammation and apoptosis. All lesions were more frequent in, but not restricted to, biopsies with rejection patterns. Grading of rejection in cervical biopsies is reproducible and applicable to biopsies from different centers. Diagnosis of rejection may be improved by adding further histological lesions to the grading system; however, lesions require rigorous consensus definition.

Hypothermic machine perfusion for uterus transplantation

To describe the feasibility of hypothermic machine perfusion (HMP) in uterus transplantation (UT) to potentially improve the preservation of the uterus and enhance graft preservation in the donation after brainstem death (DBD) context. Uterus transplantation is a new surgical approach to treating absolute uterine infertility; it can be performed after living donation or after DBD. In the DBD context, the uterus is typically the last organ removed after other vital organs, with the exception of the Baylor team, which removes the uterus first. This key aspect imposes an unavoidable mild temperature ischemia for >1 hour on the uterus during the removal of the vital abdominal and chest organs. In renal transplantation, the perfusion machine reduces the risk of delayed graft function; thus, we hypothesized that machine perfusion could result in a reduction of uterus graft dysfunction. The uterus graft dysfunction could be expressed by a low embryo implantation rate, pregnancy loss, or vascular pregnancy diseases such as preeclampsia or fetal growth restriction." To date, static cold storage of the uterus is the only standard method for preservation before transplantation. HMP is an emerging method that could potentially improve the preservation of the uterus to enhance graft preservation in the DBD context. This video article shows all the technical details of using the HMP for uterine transplantation. University. Porcine model. Porcine uterus was retrieved from a DBD domestic animal model and flushed with KPS MP (Bridge To Life Ltd in UK) at 4 °C. After vascular preparation on the back table, the uterus was perfused using KPS MP through a cannula in the aorta using the VitaSmart device (Bridge To Life Ltd in UK) for 18 hours. Then, the uterus was transplanted to the porcine recipient. The macroscopic appearance of the uterus at the end of HMP and the assessment of the uterus vascularization after transplantation in the recipient compared with the native uterus. This video shows the cannulation of the iliac vessels, cooling and removal of the uterus on a porcine model, uterus preservation using HMP during 18 hours, and then UT in a new recipient pig with the reperfusion of the transplanted uterus next to the native, intact uterus of the recipient. The macroscopic appearance of the uterus at the end of HMP appeared viable and was perfectly flushed. The assessment of the uterus vascularization after transplantation in the recipient was similar to that of the native uterus. To our knowledge, we describe here for the first time the UT procedure in DBD context on an animal model and the use of HMP for uterus preservation in UT programs; this could increase the number of uterine grafts available for a greater number of femalerecipients. Hypothermic machine perfusion could allow the duration of cold ischemia to be prolonged without altering the uterine graft. Nevertheless, this assertion has to be validated in a human context.

Psychosocial Outcomes in Nondirected Uterus Donors 1 Y After Donation.

As uterus transplantation transitions to a clinical procedure for women with absolute uterine-factor infertility, transplant centers performing uterus transplantation need information about the experience of living donors. This study examined the psychosocial impact on 17 nondirected uterus donors in the Dallas UtErus Transplant Study 1 y following donation. A prospective longitudinal study was conducted to measure psychosocial outcomes of depression, anxiety, posttraumatic stress, quality of life, and resilience [measured using the Hospital Anxiety and Depression Scale or Patient Health Questionnaire 9-Item, Generalized Anxiety Disorder 7-Item, Posttraumatic Stress Disorder Checklist for the DSM-5, health-related quality of life Short Form-36, and Connor-Davidson Resilience Scale 10-Item, respectively) assessed at baseline, at 6-mo and 1-y follow-up. Differences among baseline, 6-mo, and 1-y postdonation were analyzed. The median age was 38.0 y, 16 were married, 15 were of non-Hispanic/Latino ethnicity. Most donors did not report psychosocial distress; however, 1 donor reported decline on the role limitations because of Emotional Problems Scale and also showed an increase in depression symptoms at the 6 mo, but at 1 y was below the clinical cutoff for depression. A second donor showed modest decline in emotional well-being. Improvements were seen in other donors on the Physical Functioning Scale and posttraumatic stress symptoms. Although most nondirected donors appeared to remain stable, both positive and negative changes were observed over the first year. Larger studies are needed to determine psychosocial risks and benefit and what additional resources might be needed to ensure optimal psychosocial outcomes.

Pregnancy management and outcome after uterus transplantation.

Uterus transplantation is a novel approach in women whose uterus is absent or severely abnormal. However, it is still an experimental procedure that poses risks to both mother and baby. To date, 32 live births after uterus transplantation have been reported in peer-reviewed journals, with several maternal, fetal and neonatal complications. The most common complications were preterm delivery, hypertensive disorders and placenta previa. Four patients experienced episodes of transplant rejection during pregnancy. The appropriate management of complicated and non-complicated pregnancies following uterus transplantation is still unresolved. In this review, obstetric outcomes after uterus transplantation and optimal management during pregnancy are discussed in light of the available data. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

No clitting! We need to talk about clitoris transplantation.

In the last two decades, genital transplants have emerged as another type of quality-of-life transplants. Successful allogenic transplantations of the uterus, ovary, testicle, and penis have all been reported. Yet, there is no discussion of clitoris transplantation in the medical literature, mass media, and everywhere else I searched. This surgery could be used for cisgender women who have a clitoral injury or disease or who have undergone female genital cutting. I examine the gender norms regarding sexuality and reproduction to show how they shape surgical advancements. My point in this paper is not to take a normative position on status of current genital transplantations. Rather, I highlight that their existence is due, at least in part, because they align with dominant gender norms: penis and testicle transplantations reinforce the importance of men's virility and the existence of "normal" male genitalia, whereas uterus and ovary transplantations uphold the conflation of women and reproduction and the strong valuing of women's fertility. That medical advances reflect cultural values is not a new claim. What is new in this paper is the discussion of how sexism norms-regarding the invisibility of the clitoris and the devaluing of women's sexual pleasure- has engendered various types of genital transplants, but not clitoris transplantation.

Attitudes, knowledge, and perceptions among women toward uterus transplantation and donation in the United Kingdom.

To assess the motivations and perceptions of the general public in the United Kingdom toward donating their uterus for Uterus Transplantation after death (UTx). A cross sectional study. A 32-item electronic questionnaire. One hundred fifty nine females over the age of 16 living in the United Kingdom, consented and took part in the study. The motivations and perceptions toward UTx among the general public including the willingness to donate and barriers preventing donation. One hundred fifty nine women completed the questionnaire. The majority had never heard of UTx (n = 107, 71%) and most were not aware the uterus could be donated after death (n = 130, 92%). 43% of the cohort were willing to donate their uterus after death (n = 57). 8% stated they wished to donate their organs but not their uterus (n = 10). 30% of women (n = 42) believed the child born following UTx would have genetic links to the donor. Over half of the respondents (n = 65, 51%) strongly agreed or agreed they would feel joy in the knowledge that donation would lead to bringing a new life into the world. A quarter of respondents strongly agreed or agreed (n = 45, 25%) that the use of their uterus by another woman would feel like an extension of life. The findings indicate a favorable opinion toward UTx and a positive attitude toward donation of the uterus after death among the general public in the United Kingdom. The findings also highlight the need for education around UTx now this therapeutic option is available.
