- Uterus transplantation (UTx) is the first available treatment for absolute uterine factor infertility, a condition due to absence of the uterus or presence of a non-functional uterus. The proof-of-concept of UTx as an infertility treatment for this group of patients occurred in 2014 in Sweden by the first birth after human UTx. That and subsequent cases of the Swedish trial were live-donor UTx procedures with laparotomy of both donor and recipient. Although results of the initial Swedish clinical UTx trial were very favorable in terms of take-home-baby rate, the drawback was the long duration (>10 h) of donor surgeries and associated long recovery periods. There exist three later publications, with uterus procurements from live donors by laparotomy with a range of surgical durations of 5.3 hours to 13 hours. Our collaborative Swedish-French team has initiated efforts to introduce minimal invasive surgery in one trial in Sweden and one in France. The principle of these UTx trials is to use modern concepts of robotic-assisted laparoscopy primarily in the live donor. There also exists a small number of published UTx procedures with donor surgery by partial conventional laparoscopy and one published case with total robotic-assisted laparoscopy procedure. This review discusses open versus minimal invasive surgery in relation to the accumulated knowledge in the field. Moreover, we propose some future directions for the development of this surgery in UTx. © 2019

- Congenital uterine aplasia, also known as Mayer-Rokitansky-Kuster-Hauser syndrome (MRKHS) is a condition associated to a non-functional uterus in the presence of functional ovaries. In a setting where surrogacy is illegal (or not accepted) and adoption is the only alternative, neovaginoplasty and subsequent uterus transplantation (UTx) can provide a route to motherhood for women with MRKHS. This review article describes a multistep process by which patients with MRKHS can achieve motherhood with their own biological child. This process involving a careful clinical diagnosis, psychological counselling, assessment of eligibility for neovagina creation and UTx, the surgical treatment, fertility treatment, and long-term follow-up was developed at the Tubingen University Hospital and in close collaboration with Sahlgrenska Academy, University of Gothenburg, Sweden, where the basic experimental and clinical groundwork for UTx was laid and the first-ever UTx procedure was performed.

- To contribute to establishing donor selection criteria based on our experience with two successful living-donor human uterus transplantations (UTx) and an aborted attempt. This interventional study included three patients with uterine agenesis, aged 23, 34, and 23 years, scheduled for UTx, and their uterus-donating mothers, aged 46, 61, and 46 years, respectively. Interventions included preoperative investigations, donor surgery, back-table preparation, and recipient surgery. Preoperative imaging, surgical data, histopathology, menstrual pattern, and uterine blood flow were the main outcome measures. In the first case (46-year-old mother/23-year-old daughter), donor/recipient surgery took 12.12/5.95 h. Regular spontaneous menstruations started 6-week post-transplantation, continuing at 24-28-day intervals throughout the 6-month observation period. Repeated follow-up cervical biopsies showed no signs of rejection. In the second case (61-year-old donor), surgery lasted 13.10 h; attempts to flush the retrieved uterus failed due to extreme resistance of the left uterine artery (UA) and inability to perfuse the right UA. Transplantation was aborted to avoid graft vessel thrombosis or insufficient blood flow during potential pregnancy. Histopathology revealed intimal fibrosis and initial sclerosis (right UA), extensive intimal fibrosis (parametric arterial segments), and subtotal arterial stenosis (myometrial vascular network). In the third case (46-year-old mother/23-year-old daughter), donor/recipient surgery took 9.05/4.52 h. Menstruations started 6-week post-transplantation. Repeated cervical biopsies showed no signs of rejection during the initial 12-week follow-up period. Meticulous preoperative evaluation of potential living uterus donors is essential. This may include selective contrast-enhanced UA angiograms and limitation of donor age, at least in donors with risk factors for atherosclerosis.

Tidskriftsartikel (refereegranskat)abstract
- Absolute uterine factor infertility, due to absence or non-function of the uterus, is one of the few major subgroups of infertility that has remained without any treatment. Uterus transplantation has now been proposed as treatment for this type of infertility. The first attempt of human uterus transplantation was in 2000. This was a live donor case, but due to suboptimal surgical solutions it resulted in a necrotic uterus being removed after 99 days. This first human case, although a failure, inspired several research groups around the globe to initiate animal-based studies to investigate uterus transplantation in relation to surgery, immunosuppression, rejection and pregnancy outcome. The research was carried out in several animal species and advanced the field substantially. In 2011, the second uterus transplantation attempt was performed, and this involved a deceased donor procedure. Although the case was surgically successful, with resumed menstruations, clinical pregnancy with live birth could not be achieved. The first clinical trial of uterus transplantation was initiated in Sweden in 2013 and involved nine live donor procedures. The world's first live birth was reported from that trial in September 2014 and this was followed by two more births within that trial in November 2014. Births after uterus transplantation has since been reported from Sweden and other centers in Europe, North America, Latin America, and Asia. Thirty human uterus transplantation procedures have been reported in the scientific literature so far but by our personal knowledge the double number of procedures have been performed. The published cases will be reviewed in detail, and we will also describe the pregnancies of the live births that have been published. A small number of graft failures have occurred. These may in part be linked to suboptimal selection of donors, specifically concerning the quality of the uterine arteries. Consequently, we will also address the issue of strategies for pre-surgical screening of donors. © 2019

- Objective: To determine whether a uterus from the mother of a woman with absolute uterine factor infertility can be transplanted to daughter and carry a pregnancy with delivery of a healthy child. Patient(s): Twenty eight-year-old woman with uterine agenesis, her male partner, and her 50-year-old mother. Intervention(s): In vitro fertilization with embryo cryopreservation before live donor uterus transplantation (UTx). Induction immunosuppression. Embryo transfer 12 months after UTx, pregnancy controls, delivery, and hysterectomy. Main Outcome Measure(s): Results of IVF-ET, parameters of pregnancy/birth, and surgical data of transplantation/cesarean section/hysterectomy. Result(s): Two IVF cycles before UTx resulted in 10 cryopreserved embryos. Donor surgery included hysterectomy with vascular pedicles of uterine vessels and proximal vessels up to and including parts of internal iliacs. Recipient surgery was by bilateral vascular connections to external iliacs, vaginal-vaginal anastomosis, and uterine fixation. Pregnancy occurred at the first single ET, and the pregnancy proceeded uneventfully until gestational week 34, when the patient developed cholestasis with intense pruritus. Cesarean section was performed at 34+6, with delivery of a healthy boy (weight 2,335 g). Hysterectomy was performed 3.5 months after delivery. The weight of the healthy child at 12 months was 9.3 kg. Grandmother (uterus donor) and mother are in good health 3 years after UTx. Conclusion(s): This is the first report of a live birth after mother-to-daughter UTx, and it also represents the second birth ever after human UTx.

- This paper aimed to describe the basic aspects of uterine transplant (UTx) research in humans, including preliminary experiences in rodents and domestic species. Studies in rats, domestic species, and non-human primates validated and optimized the UTx procedure in terms of its surgical aspects, immunosuppression, rejection diagnosis, peculiarities of pregnancy in immunosuppressed patients, and patients with special uterine conditions. In animal species, the first live birth from UTx was achieved in a syngeneic mouse model in 2003. Twenty-five UTx procedures have been performed in humans. The first two cases were unsuccessful, but established the need for rigorous research to improve success rates. As a result of a controlled clinical study under a strictly designed research protocol, nine subsequent UTx procedures have resulted in six healthy live births, the first of them in 2014. Further failed UTx procedures have been performed in China, Czech Republic, Brazil, Germany, and the United States, most of which using living donors. Albeit still an experimental procedure in, UTx is the first potential alternative for the treatment of absolute uterine factor infertility (AUFI). © 2017, Sociedade Brasileira de Reproducao Assistida.

- Despite progress in the field of decellularization and recellularization, the outcome for pancreas has not been adequate. This might be due to the challenging dual nature of pancreas with both endocrine and exocrine tissues. We aimed to develop a novel and efficient cold-perfusion method for decellularization of porcine pancreas and recellularize acellular scaffolds with human fetal pancreatic stem cells. Decellularization of whole porcine pancreas at 4 degrees C with sodium deoxycholate, Triton X-100 and DNase efficiently removed cellular material, while preserving the extracellular matrix structure. Furthermore, recellularization of acellular pieces with human fetal pancreatic stem cells for 14 days showed attached and proliferating cells. Both endocrine (C-peptide and PDX1) and exocrine (glucagon and -amylase) markers were expressed in recellularized tissues. Thus, cold-perfusion can successfully decellularize porcine pancreas, which when recellularized with human fetal pancreatic stem cells shows relevant endocrine and exocrine phenotypes. Decellularized pancreas is a promising biomaterial and might translate to clinical relevance for treatment of diabetes.

- STUDY QUESTION: What are the effects on donors' health-related quality-of-life, mood and marital relationship 2 and 3years after uterus donation for transplantation? SUMMARY ANSWER: Overall, uterus donors were relatively stable regarding health-related quality-of-life, mood and marital relationship after donation, although slight negative deviations existed in a few participants, presumably associated with older age or with continued non-pregnancy outcomes from the donation. WHAT IS KNOWN ALREADY: Uterus transplantation has recently proved to be a successful treatment for absolute uterine factor infertility. However, there is no previous research on health-related quality-of-life and long-term psychosocial outcomes of donors. The present cohort of nine donors represents the cases of the first clinical uterus transplantation study, which took place in Sweden. Long-term follow-up studies of health-related quality-of-life in other living donors, such as of kidneys and livers, suggest that donors have above average quality-of-life prior to donation and that this typically continues during the years after donation. In our previous 1-year report on psychosocial and quality-of-life outcomes, we found that two out of nine donors showed decreased health-related quality-of-life at 6 and 12months post donation. STUDY DESIGN, SIZE, DURATION: This complete, prospective cohort study included the nine donors of the first uterus transplantation trial, which took place in Sweden in 2013. Donors were assessed by questionnaires 2 and 3years after surgery for uterus donation. PARTICIPANTS/MATERIALS, SETTING, METHODS: The nine donors (aged 39 to 62years) were all a close relative or friend of their recipient. Physical and mental component summaries of health-related quality-of-life were measured with the SF-36 questionnaire. Mood was assessed by the Hospital Anxiety Depression Scale. Relationship with partner was measured with the Dyadic Adjustment Scale. MAIN RESULTS AND THE ROLE OF CHANCE: The physical and mental components of the SF-36 were generally above the mean scores for a normative population. At Year 3, the two oldest donors (above 60years of age at surgery) showed clear negative deviations in the physical component. The mental component summary of SF-36 was essentially unaltered overall at Year 2, but slight negative deviations were seen in three donors at Year 3. These three donors were among the four with unsuccessful pregnancy outcomes for the recipients following donation. Scores of anxiety and depression (mood) were within normative values for all donors at Year 2, but one donor presented with increased (worse) values for both variables at Year 3. Two donors showed signs of relationship distress during the follow-up period and another had divorced during this period. LIMITATIONS, REASONS FOR CAUTION: The small sample size is a limitation. WIDER IMPLICATIONS OF THE FINDINGS: The present study suggests that live uterus donation does not in general negatively influence health-related quality-of-life, mood and relationship in a 2 to 3-year perspective follow-up. Longer follow-up studies, including larger number of donors and in different cultural settings, are needed.
