Unique risk factors for unplanned preterm delivery in the uterus transplant recipient.

STUDY QUESTION: Do characteristics of the lower uterine segment and cervix modify the risk of preterm delivery in uterus transplant (UTx) recipients? SUMMARY ANSWER: The cervical length showed little association with preterm delivery, however, cervical inflammation deserves further exploration as a cause of preterm delivery. WHAT IS KNOWN ALREADY: UTx recipients do not have the risk factors normally used to stratify pregnancies that would benefit from cervical length assessment. In addition, unique factors related to absent tissues, a different blood supply, inflammatory processes of rejection, cervical biopsies, and a different microbiome challenge the normal progressive remodeling of the cervix and thus cervical competence. STUDY DESIGN, SIZE, DURATION: This is a subanalysis of a clinical trial of 20 women undergoing uterus transplantation at Baylor University Medical Center from 2016 to 2020, in addition to two women who received transplantation outside of a research protocol at our institution through September 2022. In this report, the first 16 UTx recipients that achieved live birth are included. PARTICIPANTS/MATERIALS, SETTING, METHODS: The focus of this study was 20 pregnancies that reached the second trimester in 16 women following UTx. We analyzed recipient, transplant, and donor factors to determine if characteristics were associated with delivery outcome. We compared obstetrical outcomes, including planned versus unplanned delivery, by factors such as number of superior venous anastomoses, warm ischemia and cold ischemia times, donor factors including cesarean sections, cervical biopsy results, and cervical ultrasound results. MAIN RESULTS AND THE ROLE OF CHANCE: Planned term deliveries occurred in 44% (8/18) of live births. Of the preterm births, 30% (3/10) were planned and 70% (7/10) were unplanned. Unplanned deliveries occurred in women with spontaneous preterm labor, severe rejection, subchorionic hematoma, and placenta previa. Cervical length in UTx recipients averaged 33.5 mm at 24 weeks and 31.5 mm at 28 weeks, comparable to values from the general population. No relationship was seen between delivery outcome and number of veins used, ischemic time, or number of previous cesarean sections. LIMITATIONS, REASONS FOR CAUTION: The study's small size allows limited conclusions. The obstetric history of all donors was limited to mode of delivery. WIDER IMPLICATIONS OF THE FINDINGS: Cervical length measurements in the UTx population are not expected to deviate from those with a native uterus. While cervical length surveillance remains important, attention must be paid to the results of cervical biopsies which are obtained to monitor rejection. Inflammatory processes seem most predictive of preterm delivery. STUDY FUNDING/COMPETING INTEREST(S): No funding was provided for this study. The authors report no conflicts of interest. TRIAL REGISTRATION NUMBER: NCT02656550.

A new bicornuate model of rat uterus transplantation.

INTRODUCTION: Uterus transplantation has revolutionized reproductive medicine for women with absolute uterine factor infertility, resulting in more than 40 reported successful live births worldwide to date. Small animal models are pivotal to refine this surgical and immunological challenging procedure aiming to enhance safety for both the mother and the child. MATERIAL AND METHODS: We established a syngeneic bicornuate uterus transplantation model in young female Lewis rats. All surgical procedures were conducted by an experienced and skilled microsurgeon who organized the learning process into multiple structured steps. Animals underwent meticulous preoperative preparation and postoperative care. Transplant success was monitored by sequential biopsies, monitoring graft viability and documenting histological changes long-term. RESULTS: Bicornuate uterus transplantation were successfully established achieving an over 70% graft survival rate with the passage of time. The bicornuate model demonstrated safety and feasibility, yielding outcomes comparable to the unicornuate model in terms of ischemia times and complications. Longitudinal biopsies were well-tolerated, enabling comprehensive monitoring throughout the study. CONCLUSIONS: Our novel bicornuate rat uterus transplantation model provides a distinctive opportunity for sequential biopsies at various intervals after transplantation and, therefore, comprehensive monitoring of graft health, viability, and identification of potential signs of rejection. Furthermore, this model allows for different interventions in each horn for comparative studies without interobserver differences contrary to the established unicornuate model. By closely replicating the clinical setting, this model stands as a valuable tool for ongoing research in the field of uterus transplantation, promoting further innovation and deeper insights into the intricacies of the uterus transplant procedure.

Attitudes toward uterus transplantation. An option for motherhood?

INTRODUCTION: Uterus transplantation is a novel surgical procedure that allows women with absolute uterine factor infertility to carry a pregnancy and give birth. While previous studies have explored the attitudes of women with absolute uterine factor infertility toward uterus transplantation, none have surveyed and compare their views with other groups of interest (Morris syndrome women, relatives of Morris syndrome and Rokitansky syndrome women, infertile women and women of childbearing age) in the same sociocultural setting. The objective of this study was to evaluate attitudes and insights regarding uterus transplantation among women with Rokitansky syndrome and other groups of interest. MATERIAL AND METHODS: We designed a cross-sectional study including five groups of women: women with Rokitansky syndrome, women with Morris syndrome, relatives of women with Morris and Rokitansky syndrome, infertile women, and childbearing-age women. We conducted an online survey through the REDCap platform. The link was distributed by mail, telephone and in hospital outpatient visits. Baseline demographic information was assessed and information regarding motherhood preferences, attitude toward uterus transplantation, preferred uterus graft and perception of risk of the procedure was collected. RESULTS: We obtained a total of 200 responses, with a mean participant age of 34.5 years (±9.8). Overall, 17.5% (n = 35) were women with Rokitansky syndrome, 5.5% (n = 11) Morris syndrome women, 21.5% (n = 43) infertile women, 26.5% (n = 53) relatives of Morris and Rokitansky syndrome women and 29% (n = 58) childbearing-age women. 71.5% of women with Rokitansky syndrome would undergo uterus transplantations ahead of adoption and surrogacy with no statistically significant differences found between groups. Overall, more than one-half (58%) would prefer deceased over living donor. CONCLUSIONS: The results of this survey indicate that uterus transplantation is desired by most women who would benefit from the procedure, including those with either Morris syndrome or absolute uterine factor infertility. This was also the preferred option for motherhood if absolute uterine factor infertility was diagnosed among surveyed infertility patients or women of childbearing age with no known reproductive difficulties. Overall, most respondents indicated a deceased donor was preferable to a living donor and that patients may not be sufficiently aware of potential risks of uterus transplantation, highlighting the importance of adequate counseling by medical providers.

Midwifery students' spiritual and ethical values and their views and attitudes towards uterine transplantation: A qualitative study.

This qualitative study was conducted to examine the relationship between Muslim midwives' spiritual values and ethical orientations and their attitudes towards uterine transplantation. The phenomenological study sample group consisted of students in the Midwifery undergraduate programme of a public university in Istanbul (n:26). The data were collected in semi-structured focus group interviews. It was among the student midwives, it was determined that some students rejected uterine transplantation with thoughts such as "I am a Muslim, according to my religious belief, I should go to the grave without damaging my organs" or "This transplantation is not a vital necessity", as well as students who considered uterine transplantation as religious and ethically appropriate. It was determined that midwife candidates who will provide reproductive health services have different ethical and moral views regarding uterus transplantation, and there are some who see this method as religiously acceptable, and there are also students who emphasize that it is not suitable for Islam. In addition, training programs are planned to increase students' awareness and knowledge on this subject, aiming to be beneficial to the women they will care for in the future.

Cette étude qualitative a été menée pour examiner la relation entre les valeurs spirituelles et les orientations éthiques des sages-femmes musulmanes et leurs attitudes à l'égard de la transplantation utérine. Le groupe échantillon de l'étude phénoménologique était composé d'étudiants du programme de premier cycle de sages-femmes d'une université publique d'Istanbul (n : 26). Les données ont été recueillies lors d'entretiens de groupe semi-structurés. Parmi les étudiantes sages-femmes, il a été déterminé que certaines étudiantes rejetaient la transplantation utérine avec des pensées telles que "Je suis musulmane, selon ma croyance religieuse, je devrais aller dans la tombe sans endommager mes organes" ou "Cette transplantation n'est pas une nécessité vitale", ainsi que des étudiants qui considéraient la transplantation utérine comme religieusement et éthiquement appropriée. Il a été déterminé que les candidates sages-femmes qui fourniront des services de santé reproductive ont des opinions éthiques et morales différentes concernant la transplantation d'utérus. Certaines personnes considèrent cette méthode comme religieusement acceptable, et d'autres étudiants soulignent qu'elle n'est pas adaptée à l'Islam. De plus, des programmes de formation sont prévus pour accroître la sensibilisation et les connaissances des étudiants sur ce sujet, dans le but d'être bénéfiques aux femmes dont elles s'occuperont à l'avenir.

Ethics of live uterus donor compensation.

In this paper, I claim that live uterus donors ought to be considered for the possibility of compensation. I support my claim on the basis of comparable arguments which have already been applied to gamete donation, surrogacy, and other kinds of organ donation. However, I acknowledge that there are specificities associated with uterus donation, which make the issue of incentive and reward a harder ethical case relative to gamete donation, surrogacy, and other kinds of organ donation. Ultimately, I contend that while reimbursement for the costs incurred by live uterus donors should be treated as a necessary ethical minimum, how much further we ought to remunerate uterus donations remains an open question.

Is suffering a sufficient legitimation for UTx?

Uterus transplantation is a relatively new intervention. A woman with absolute uterine factor infertility receives, by a surgical procedure, a transplanted uterus, most often by living donation. The uterus recipient may thus become pregnant and conceive her own child. As with any other medical treatment, UTx requires legitimation. The anticipated benefits must outweigh the risks of the medical intervention. The risks and benefits of UTx are by no means unequivocal and cannot be easily determined. The benefits depend on the final evaluation of the suffering to be alleviated by the intervention. In the following, we will analyze the suffering addressed by UTx and discuss its normative value. First, we point out that (a) suffering is generally considered an important normative criterion in medicine as well as in the context of UTx; (b) we then describe the risks and anticipated benefits of UTx for the three persons directly concerned: the child, the donor, and the recipient; (c) we further analyze the suffering addressed by UTx. The intervention addresses a form of existential suffering. We discuss the common notion that existential suffering should be evaluated from the subjective perspective of the sufferer; (d) afterwards, we argue that in a social practice like medicine, a one-sided evaluation stemming from the sufferer alone is not sufficient; and (e) finally, arguments from a societal perspective lead us to the conclusion that the existential suffering addressed by UTx does not possess a sufficiently strong normative value to legitimize a high-risk, expensive procedure.

Equality-enhancing potential of novel forms of assisted gestation: Perspectives of reproductive rights advocates.

Novel forms of assisted gestation-uterus transplantation and artificial placentas-are highly anticipated in the ethico-legal literature for their capacity to enhance reproductive autonomy. There are also, however, significant challenges anticipated in the development of novel forms of assisted gestation. While there is a normative exploration of these challenges in the literature, there has not yet, to my knowledge, been empirical research undertaken to explore what reproductive rights organisations and advocates identify as potential benefits and challenges. This perspective is invaluable. These organisations/individuals have an awareness not only of the needs of individuals but also of the political landscape in which regulatory decisions are made and which individuals navigate when seeking reproductive assistance. In this study, data was generated from two semi-structured focus groups (n = 11). Reflective thematic analysis was used to examine the views raised by study participants in these focus groups. This paper explores two of the themes constructed in the data. First, the equality-enhancing potential of assisted gestation exploring the multifaceted ways in which assisted gestation has structural benefits for marginalised groups. Second, realising the equality-enhancing potential of assisted gestation explores the intersecting barriers to access to reproductive technologies and how they may impede the benefits of these technologies in practice. These results can enhance conceptual understanding of the importance of novel forms of assisted gestation and ensure that attention is paid to practical barriers in further normative research.

How Surgical Research Gave Birth to a New Clinical Surgical Field: A Viewpoint from the Dallas Uterus Transplant Study.

BACKGROUND: Uterus transplantation (UTx) has come of age in the 21st century, building on the 20th century developments in vascular anastomosis and effective immunosuppressive protocols that have enabled solid organ transplantation to become the life-extending and life-improving treatment option we know today. However, UTx has the goal of enabling reproduction, meaning that research has focused on establishment of pregnancy and healthy live birth in addition to surgical technique and immunosuppression. SUMMARY: The Dallas Uterus Transplant Study (DUETS), established at Baylor University Medical Center in 2015, is one of four UTx programs in the USA, and it holds the distinction of being home not only to the first US live birth but also the highest volume UTx program worldwide, with 23 uterus transplants performed to date, resulting in 15 live births. Innovations pioneered at our center span all aspects of the UTx process, all seeking to improve success for recipients in terms of achieving pregnancy and live birth, while also minimizing the burden on donors and recipients. They have included the following: (1) a deceased donor hysterectomy approach that allows the uterus to be procured prior to cross clamp; (2) proof of concept with use of only superior uterine veins after procuring both the superior and inferior uterine veins during the donor surgery, enabling the choice of the best option in terms of size and location for outflow, while also preserving ovary viability in living donors; (3) contribution to robot-assisted technique/minimally invasive technique with vaginal extraction of the uterus graft for living donor surgeries, shortening donor recovery times; (4) developing a robot-assisted technique for graft hysterectomies, improving recovery times for recipients at the end of their UTx journey; (5) refining immunosuppression protocols to enable embryo transfer as early as 3 months after induction therapy, increasing recipients' chances for achieving up to two live births during the 5 years posttransplant the UTx protocol specifies; and (6) building on our clinical trial experience to now offer UTx in the U.S. outside the setting of a clinical study. KEY MESSAGES: Our center along with others throughout the world has demonstrated that UTx can be reproducible, result in live births from both living and deceased donors, and be safely introduced as a clinical option. Due to the complexity of UTx as well as the need for long-term multidisciplinary care, centers implementing UTx should have an established abdominal transplant program, a gynecologic surgery program, high-risk obstetric and neonatal care, and institutional support and oversight, and should partner with established UTx programs for protocol development and operative proctoring.

Procedures and technical considerations of robotic-assisted human uterus transplantation.

BACKGROUND: Uterus transplantation is the only treatment for absolute uterine factor infertility. Complex vascular anatomy, long operation time, and intraoperative injuries are the main factors that limit progress in uterus transplantation. Moreover, robot-assisted uterus transplantation is not popular at present due to technical difficulties, with only a few countries reporting success. METHODS: In this paper, we present the key technical points of robot-assisted uterine transplantation by analyzing and summarizing our surgical experience and other successful cases of robot-assisted uterine transplantation. This study provides an evidence-based reference for clinicians planning robot-assisted uterine transplantation procedures. CONCLUSION: Minimally invasive technologies can shorten the operation time, reduce injuries, and contribute to analyzing the anatomy of complex blood vessels. Therefore, robot-assisted uterine transplantation is an important direction for the future of uterine transplantation, and the findings and procedures reported herein contribute to the standardization and promotion of robot-assisted uterine transplantation operations.

Uterine allograft removal by total laparoscopic hysterectomy after successful cesarean delivery in a living-donor uterus recipient with uterovaginal agenesis (MRKHS).

PURPOSE: To limit the burden of long-term immunosuppression (IS) after uterus transplantation (UTx), removal of the uterine allograft is indicated after maximum two pregnancies. Hitherto this has required graft hysterectomy by laparotomy. Our objective was to demonstrate, as a proof of concept, the feasibility of less traumatic transplantectomy by total laparoscopic hysterectomy (TLH). PATIENT: A 37-year-old woman with uterovaginal agenesis due to Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) who had undergone neovaginoplasty at age 19 years prior to living-donor (LD) UTx in 10/2019 at age 35 years gave birth to a healthy boy by primary cesarean section in 06/2021. During pregnancy, she developed impaired renal function, with bilateral hydronephrosis, necessitating early allograft removal in 09/2021 to prevent chronic kidney disease, particularly during a potential second pregnancy. METHODS: Transplantectomy by TLH essentially followed standard TLH procedures. We paid meticulous attention to removing as much donor tissue as possible to prevent postoperative complications from residual donor tissue after stopping IS, as well as long-term vascular damage. RESULTS: TLH was performed successfully without the need to convert to open surgery. Surgical time was 90 min with minimal blood loss. No major complications occurred intra- or postoperatively and during the subsequent 9-month follow-up period. Kidney function normalized. CONCLUSIONS: To our knowledge, we report the first successful TLH-based removal of a uterine allograft in a primipara after LD UTx, thus demonstrating the feasibility of TLH in uterus recipients with MRKHS.

Ethical issues raised by uterus transplantation: A report from the People's Republic of China.

The recent advances in assisted reproductive technology, such as hormonal stimulation, IVF, and intracytoplasmic sperm injection (ICSI), have made it possible to circumvent many causes of male and female factor infertility. However, uterine infertility is still considered an ''unconditionally infertile'' condition. Owing to the continued advances in organ transplantation, microvascular anastomosis techniques, and immunosuppressive medicine, the transplantation of organs is no longer restricted to the ones necessary for continued life. Quality-of-life enhancing types of transplantation, such as uterine transplantation, in recent years, have also entered the clinical arena. This undoubtedly brings new hope to such women, but also creates ethical challenges. Selection of the donor, the impact on the recipient and offspring, as well as challenges to moral and social norms are issues that cannot be ignored. In the present review, the ethical issues of transplantation of the uterus will be discussed in light of recent progress in the procedure.

The journey from infertility to uterus transplantation: A qualitative study of the perspectives of participants in the Dallas Uterus Transplant Study.

OBJECTIVE: To assess how absolute uterine factor infertility affects women who undergo uterus transplantation, how uterus transplantation impacts women with absolute uterine factor infertility and how uterus transplant recipients view uterus transplantation in terms of their reproductive autonomy. DESIGN: Qualitative semi-structured interview study. SETTING: Uterus transplant programme in a large academic medical centre in the USA. POPULATION/SAMPLE: Twenty one uterus transplant recipients. METHODS: A medical chart review was conducted to collect patient demographic information and clinical outcomes. Semi-structured interviews collected information regarding participants' experience. MAIN OUTCOME MEASURE(S): The outcomes of interest were participants' experience of infertility, experience with uterus transplantation and general perceptions of uterus transplantation. RESULTS: Six participants were pregnant (one with a second child), six had experienced early graft failure and removal, five had delivered a healthy baby, and four had a viable graft and were awaiting embryo transfer. The primary themes identified were: the negative impact of absolute uterine factor infertility diagnosis on psychological wellbeing, relationships and female identity; the positive impact of uterus transplantation on healing the emotional scars of absolute uterine factor infertility, female identity and value of research trial participation and the perception of uterus transplantation as an expansion of reproductive autonomy. All participants reported that uterus transplantation was worthwhile, regardless of individual outcome. CONCLUSION: Absolute uterine factor infertility has a negative impact on women from a young age, affects multiple relationships and challenges female identity. Uterus transplantation helps to reverse this impact, transforming women's life narrative of infertility and enhancing female identity. TWEETABLE ABSTRACT: Absolute uterine factor infertility (AUFI) adversely affects women. Uterus transplantation helps mitigate the negative impact of AUFI, by transforming women's life narratives of infertility and enhancing female identity.

Children after uterus transplantation: 2-year outcomes from the Dallas UtErus Transplant Study (DUETS).

OBJECTIVE: To describe outcomes in the first 2 years of life for the children born in the Dallas UtErus Transplant Study. DESIGN: Cohort study comprising all live births from uterus transplantation at a single centre. SETTING: Baylor University Medical Center, Dallas, Texas. POPULATION: A total of 14 children from 12 uterus transplantation recipients. METHODS: Retrospective review of data through 2 years of life. MAIN OUTCOME MEASURES: Information on children's development was collected based on the Bright Futures Guideline and the Bright Futures Previsit Questionnaire. Primary outcomes were anthropometric measures (children's body length, weight, head circumference), neurological status, cognitive status and physical development at 6, 12, 18 and 24 months of age. RESULTS: The median gestational age at delivery was 36+6  weeks, with a median birthweight of 2940 g. Follow-up data were available for 13 offspring. Physical and neurological developmental milestones were met and were age appropriate in all children within the first 24 months. General health was good, and no abnormalities in immune development were found. Cognitive deviations were only mild and temporary and improved with interventions. CONCLUSIONS: The children's growth and physical, neurological and cognitive development were age appropriate within the first 2 years of life. To confirm these outcomes, further data should be collected in collaboration with other centres.

Histopathological examination of the ectocervical biopsy in non-transplanted uteri: A study contributing to the provisional scoring system of subclinical graft rejection after uterus transplantation.

INTRODUCTION: Uterus transplantation is a causal treatment for absolute uterine factor infertility. Assessing rejection signs using a histopathological examination of the ectocervical biopsy from the transplanted uterus is common practice in all human uterus transplants worldwide to date. A provisional scoring system was used for the histopathological assessment of subclinical rejection signs in uterus recipients. Here we hypothesized that histopathological and immunohistochemical findings in the normal uteri would differ from the borderline category of subclinical rejection in uterine transplants. MATERIAL AND METHODS: This prospective observational study included ectocervical biopsies of 54 women who underwent hysterectomy for benign reasons. All biopsy samples were assessed histopathologically and immunohistochemically. RESULTS: Most of the ectocervical biopsies showed clustering lymphocytic infiltrates affecting the stromal-epithelial interface with the epithelial influx of lymphocytes, primarily CD45RO-positive activated T-cells with CD8 T-lymphocyte predominance. CD4-positive T-lymphocytes and B-cells were rarely detected in the ectocervix. These morphological findings and immunoprofiles of lymphocytic populations overlapped with the so-called borderline changes defined in the provisional scoring system for rejection in the transplanted uteri. The immunoprofiles of ectocervical and endocervical lymphocytic populations differed, with strikingly prominent B-cell participation in the endocervix vs the rare detection of B-cells in the ectocervix. CONCLUSIONS: The histopathological and immunohistochemical findings in the uteri of premenopausal women were similar to the borderline category of the currently used provisional scoring system of subclinical uterine rejection utilized in all uterine transplant studies. However, future similar studies are required to validate our findings.

Persons and women, not womb-givers: Reflections on gestational surrogacy and uterus transplantation.

In a recent article in this journal, Alex Mullock, Elizabeth Chloe Romanis and Dunja Begovic provide an analysis of gestational surrogacy and uterus transplantation (UTx) from the perspective of those who may decide to act as gestational surrogates and womb donors, referred to as 'womb-givers'. In this article, I advance two sets of claims aimed at critically engaging with some aspects of their analysis. Firstly, I argue that the expression 'womb-givers' obscures the biologically, socially and politically salient issue that those who engage in these practices are primarily persons and women. My contention is that this is of substance in discussions of the burdens and benefits of gestational surrogacy and UTx, which need to consider the specific position that women occupy in society, and the hierarchies that mediate their lives, experiences and preferences. Second, I argue that, if one were to take seriously the experiences and preferences of the women who may engage in these practices, and their bodily autonomy, then gestational surrogacy and UTx should be regarded as biologically and sociopolitically incommensurable. Mullock et al. overlook important aspects of gestational surrogacy, such as the embodied nature of pregnancy and childbirth, the sociopolitical significance of these experiences, and the often-oppressive social norms that shape them. Whilst biology is not destiny, I suggest that it is socially and politically 'sticky' when it comes to this significance and norms, especially within the sphere of reproduction. Towards the end of the article, I query the authors' conceptualisation of bodily autonomy and of the instruments that enable its respect and promotion.

Early initiation of embryo transfers after uterus transplantation to shorten the administration of immunosuppressive therapy.

Uterus transplantation seems to be a promising method for the causal treatment of absolute uterine factor infertility in women with an absent or non-functional uterus. Since uterus transplantation is still experimental in nature, there are no strict guidelines regarding each step of this comprehensive treatment method. Prior to uterus transplantation, ovarian stimulation and in vitro fertilization are performed on the potential uterus recipient, and the obtained embryos are cryopreserved and stored for the transfers after transplantation when only non-fetotoxic maintenance immunosuppressants are administered. In the first human uterus transplantation study, the start of embryo transfers was set at 12 months after transplantation. Due to the growing experience, especially with early rejections after transplantation and the course of pregnancy, several ongoing studies have experimentally shortened the uterus transplant-to-embryo transfer interval to 6 months. Shortening the total time of immunosuppression administration after uterus transplantation is the main reason for early initiation of embryo transfers after transplantation. However, the safety of an interval of less than one year between uterine transplantation and the first post-transplant embryo transfer should be further studied.

Clinical pregnancy rates and experience with in vitro fertilization after uterus transplantation: Dallas Uterus Transplant Study.

BACKGROUND: The clinical pregnancy rates among patients with uterus transplantation have been reported by only a limited number of centers, and those centers have not used preimplantation genetic testing for aneuploidy in their protocol. OBJECTIVE: This study examined clinical pregnancy rates among women with absolute uterine-factor infertility undergoing in vitro fertilization using good-quality, expanded-blastocyst-stage, euploid embryos after uterus transplantation. STUDY DESIGN: This cohort observational study involved 20 women who underwent uterus transplantation over 3 years. Notably, 14 of these patients had successful transplants and were followed prospectively for a median of 14.1 months (range, 11-34.8 months). In vitro fertilization was performed before subjects underwent uterus transplantation, and good-quality expanded-blastocyst-stage euploid embryos were obtained and frozen for future embryo transfer. Interventions consisted of in vitro fertilization, preimplantation genetic testing for aneuploidy, uterus transplantation, and frozen embryo transfer. RESULTS: All 14 subjects with successful transplants underwent single embryo transfer of a warmed, good-quality, euploid, expanded blastocyst and had at least 1 documented clinical pregnancy within the uterus. In 71.4%, the first embryo transfer resulted in clinical pregnancy. The median time from successful uterus transplantation to first embryo transfer was 4.5 months; from successful uterus transplantation to first clinical pregnancy, 7.3 months; and from successful uterus transplantation to first live birth, 14.1 months. A total of 13 live births have occurred in 12 subjects. CONCLUSION: Women with absolute uterine-factor infertility who have surgically successful uterus transplantation and in vitro fertilization using preimplantation genetic testing for aneuploidy can achieve high clinical pregnancy rates. We have reduced the time interval from uterus transplantation to embryo transfer by at least 50% and the interval from uterus transplantation to clinical pregnancy by >6 months compared with previous studies. We believe our approach may shorten the time from transplant to clinical pregnancy and therefore decrease patient exposure to immunosuppressant therapies.

Successful trachelectomy and re-vaginoplasty for cervico-vaginal stenosis following unsuccessful uterovaginal anastomosis and vaginoplasty in congenital cervical and vaginal aplasia: description of technique and a case report.

We describe a successful surgical technique of abdominal trachelectomy and re-vaginoplasty for cervico-vaginal stenosis following unsuccessful uterovaginal anastomosis and vaginoplasty in a patient with congenital cervical and vaginal aplasia. After the surgical procedure, cervico-vaginal stenosis was resolved and periodic menstruation without dysmenorrhoea resumed. While long-term follow-up is essential to ensure successful pregnancy and delivery, we conclude that this novel surgical procedure is a promising alternative for improvement of the quality of life and normal sexual function, and for preservation of fertility in patients with cervical and vaginal aplasia.

Pregnancy after CMV infection following uterus transplantation: A case report from the Dallas Uterus Transplant Study.

Uterus transplantation is a repeatedly proven treatment for women with absolute uterine-factor infertility, which is the congenital or acquired absence of the uterus, who desire to carry, and ultimately deliver, a child. No stranger to the field of transplant or obstetrics is cytomegalovirus. Cytomegalovirus is both a frequent complication after transplant, presenting as an opportunistic infection, and a common congenital disease in the newborn child from pregnancy. To date, there have been no reported cases of pregnancy following uterus transplantation from cytomegalovirus-positive donors into cytomegalovirus-negative recipients. We present a case report describing our experience of a cytomegalovirus-negative recipient, transplanted with a uterus from a cytomegalovirus-positive living donor, and subsequently diagnosed with active cytomegalovirus infection despite prophylactic treatment. She was treated for infection prior to embryo transfer and carried a healthy child to term. This case suggests transplanting a cytomegalovirus-positive uterus into a negative donor is possible to do safely.

Public funding of uterus transplantation: Deepening the socio-moral critique.

Human uterus transplantation (UTx)-the most radical and experimental of all current forms of assisted reproduction-gives rise to a range of complex ethical questions, including those related to individual safety, risk, and informed consent. I have argued elsewhere that the wider social impacts and implications of UTx provision must form part of a comprehensive ethical analysis. My socio-moral critique of UTx provision has been responded to with a number of defences of possible public funding of UTx. In this paper I examine a select number of those defences. These include: that UTx provision would address harms and needs that already exist and as such have priority; that UTx provision is fully compatible with the needed reform of the procreative context in which it would be offered; that UTx provision would not necessarily involve legitimation or endorsement of what are widely agreed to be problematic pronatalist or geneticist norms; and that UTx provision is required as a matter of justice and consistency with other practices. Importantly, defenders are not proposing a ceteris paribus justification of UTx provision; nor do my responses to their arguments represent a comprehensive opposition to UTx. Rather, my more limited purpose here is to show that whatever other defences may be given of publicly funded UTx provision, those considered here do not ultimately succeed and therefore do not allay the concerns underpinning the original socio-moral critique.
