Uterus transplantation (UTx) can provide a route to motherhood for women with Mayer–Rokitansky–Küster–Hauser syndrome (MRKHS), a congenital disorder characterized by uterovaginal aplasia, but with functional ovaries. Based on our four successful living-donor transplantations and two resulting births, this analysis presents parameters relevant to standardizing recipient/donor selection, UTx surgery, and postoperative treatment, and their implementation in routine settings. We descriptively analyzed prospectively collected observational data from our four uterus recipients, all with MRKHS, their living donors, and the two newborns born to two recipients, including 1-year postnatal follow-ups. Analysis included only living-donor/recipient pairs with completed donor/recipient surgery. Two recipients, both requiring ovarian restimulation under immunosuppression after missed pregnancy loss in one case and no pregnancy in the other, each delivered a healthy boy by cesarean section. We conclude that parameters crucial to successful transplantation, pregnancy, and childbirth include careful selection of donor/recipient pairs, donor organ quality, meticulous surgical technique, a multidisciplinary team approach, and comprehensive follow-up. Surgery duration and blood vessel selection await further optimization, as do the choice and duration of immunosuppression, which are crucial to timing the first embryo transfer. Data need to be collected in an international registry due to the low prevalence of MRKHS.

Congenital uterovaginal aplasia commonly occurs in Mayer-Rokitansky-K€ uster-Hauser syndrome. Various methods of neovagina creation exist, including nonsurgical self-dilation, surgical dilation, and surgical procedures involving skin or intestinal transplants. Subsequent uterus transplantation is necessary to enable pregnancy. We review the main characteristics, advantages, and disadvantages of established neovagina creation methods and discuss their suitability regarding subsequent uterus transplantation. Suitability criteria include sufficient vaginal length, absence of previous major intra-abdominal surgery, a natural vaginal axis, and a natural vaginal epithelium. In conclusion, Vecchietti-based laparoscopically assisted neovagina creation provides ideal functional conditions for uterus transplantation. Nonsurgical self-dilation and Wharton-Sheares-George vaginoplasty may also be suitable.

Objective: To report our experience with the screening and selection of potential recipients and living donors of our uterus transplantation (UTx) program. Design: Part of an observational program. Setting: University hospital. Patient(s): Patients with absolute uterine factor infertility (AUFI). Intervention(s): Screening by e-mail and telephone, selection during surgical consultation, and preoperative investigations according to a multistep procedure for living donation. Main Outcome Measure(s): Age, cause of AUFI, exclusion reasons, and preoperative workup. Result(s): A total of 212 potential recipients expressed interest in participation. Among the 46 potential recipients and 49 directed donors were 4 potential recipients, each with 2 directed donors. Mean (range) age of potential recipients was 29.6 (19-41) years. Of the potential recipients, 39 (84.8%) had congenital AUFI and 7 (17.3%) had acquired AUFI. Ultimately, 15 potential recipients with 16 directed donors were selected for participation, with 1 potential recipient having 2 directed donors. Mean age of included potential recipients was 28.9 (22-35) years, and mean donor age was 51.3 (37-62) years. Fourteen potential recipients (93.3%) had congenital AUFI, and one potential recipient (6.7%) had undergone hysterectomy for obstetric complications. Conclusion(s): The number of potential candidates for UTx is not inconsiderable, with congenital AUFI being the leading cause of AUFI in our cohort. However, our findings highlight that large numbers of AUFI patients need to be screened, considering our exclusion rates were >50%, owing to ABO incompatibility, unavailability of a directed donor, and self-withdrawal. Moreover, meticulous preoperative screening, including in-depth psychological assessment, is mandatory to maximize living donor safety and UTx success. (Fertil Steril Ò 2019;111:186-93.

Background/Aims: Uterine rudiments from patients with Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) contain all tissues typically found in the uterus. Endometrium from the rudiments predominantly exhibits basalis-like features, and endometrial proliferative capacity in patients’ epithelium and stroma is significantly lower. Methods: This single-center, prospective study conducted at a major German university hospital compared in-vitro decidualization in cultured ESCs from MRKHS patients and hysterectomy controls. Primary ESC cultures were established from both sources. Hormone-induced prolactin and IGFBP-1 secretion served as a measure of their ability to undergo decidualization in response to hormonal stimulation. Expression levels of 8 key marker genes of decidualization were also determined. Results: At day 9, mean secretion of prolactin and IGFBP-1 was significantly reduced by 89.0% and 99.5%, respectively, in MRKHS ESCs vs. hysterectomy controls, both indicating impaired decidualization of MRKHS ESCs. Key decidual markers confirmed impaired decidualization in MRKHS patients. Conclusion: Our results indicate that the ESCs from MRKHS patients lack hormone responsiveness as a potential sign of dysfunctional hormone receptor function, which may also play a role in the onset of MRKHS. Further studies are needed to corroborate our findings, directly address receptor function, and elucidate the role of other potential determinants of uterine development and adult function.

The identified variants on DNA level might impair receptor function through different molecular mechanisms. Mutations of ESR1 and OXTR are associated with MRKHS. Thus, we consider these genes potential candidates associated with the manifestation of MRKHS.

Objective The main objectives of our study were to demonstrate that laparoscopic supracervical hysterectomy (LSH) or total laparoscopic hysterectomy (TLH) can be performed safely even in patients with a uterine weight ≥ 500 g, to analyze the rate of conversions to laparotomy due to uterine size and to estimate the incidence and type of intraoperative and long-term postoperative complications. Study Design Retrospective open, single-center, comparative interventional study of LSH and TLH. Results The present study comprised a total of 138 patients that underwent laparoscopic hysterectomy with a uterine weight ≥ 500 g; 109 patients (79.0 %) underwent LSH and 29 patients (21.0 %) underwent TLH. Median uterine weight across the entire cohort was 602 g, with the largest uterus weighing 1860 g. A total of 24 cases (17.4 %) among the 138 hysterectomies were converted to a laparotomy due to lack of adequate intraabdominal space and size of the uterus. Mean uterine weight of the patients in the LSH group that underwent conversion was 883 g (SD 380 g, n = 13) and 757 g (SD 371 g, n = 11) in

Background: The Mayer-Rokitansky-Küster-Hauser syndrome, MRKHS, is a rare (orphan) disease characterized by the aplasia or hypoplasia of the uterus and the vagina. In women's health research, little is known as to how much care provision for patients with MRKHS takes into account their socio-demographic together with their clinical characteristics. This work examines the patients' socio-demographic characteristics, highlighting issues of inappropriate and deficient provision of care. Methods: The study was carried out as part of the larger TransCareO project and included a group of N=129 MRKHS patients who underwent surgery between 2008 and 2012. Using a specially developed questionnaire, we analyzed MRKHS patients' data found both in the clinical documentation of the Department for Women's Health, University Hospital of Tübingen and the patient surveys of the Center for Rare Genital Malformations (CRGM/ ZSGF). Patients who took part in interviews were compared with non-respondents. Results: Patient respondents and non-respondents did not differ as to the parameters of interest. In most cases, primary amenorrhea was reported as an admission reason. In 24% of patients, a medical intervention (hymenal incision or hormone treatment) already occurred before admission to the Center in Tübingen and proper diagnosis of MRKHS. About one third received in advance inappropriate treatment. During the therapy, more than half of the patients were in a solid partnership. 10% of the family anamneses documented the occurrence of urogenital malformations.
