In recent years, advances in organ transplantation medicine have led to an increase in pregnancies and births following transplantation. Pregnancy after organ transplantation is considered high-risk, and its impact on both the recipient and the child must be carefully evaluated. In this review, we summarize the current landscape of pregnancy and childbirth after organ transplantation, with a particular focus on uterus transplantation (UTx). Traditionally, organ transplants have involved vital organs; however, UTx, developed for women with absolute uterine factor infertility, represents a novel approach. Although the number of births following UTx remains limited, it is expected to grow due to the international expansion of this procedure. Importantly, the concept of pregnancy and delivery following UTx is fundamentally different from that of other organ transplants. UTx is a life-enhancing, non-vital, and temporary transplant uniquely intended to enable the creation of new life. Pregnancy after UTx carries specific risks such as a higher incidence of miscarriage, preterm birth, hypertensive disorders of pregnancy, and gestational diabetes. All deliveries are performed via cesarean section, and conception is typically allowed after a relatively short period following transplantation, given the temporary nature of the graft and the goal to minimize recipient burden, with generally good neonatal outcomes. As pregnancies after both solid organ transplantation and UTx continue to rise worldwide, the development of standardized, organ-specific perinatal management strategies, particularly for UTx, is essential. Multidisciplinary collaboration will be critical to supporting these high-risk pregnancies and ensuring the best possible maternal and neonatal outcomes. Full article

Background: Vaginal reconstruction procedures for patients with Mayer–Rokitansky–Küster–Hauser syndrome (MRKH) have the main purpose of restoring the anatomy to increase the quality of life of these patients. To describe the surgical treatment of patients with type I Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome with complete vaginal agenesis in 10 steps, using a sacropexy technique by a double approach (laparoscopic and perineal), which could help make this procedure more accessible and safer. Methods: The surgical technique was used in a group of three patients diagnosed with MRKH syndrome with vaginal agenesis, in which a neovagina with peritoneal flaps was created, and the reconstruction of the vaginal apex and its sacropexy created the conditions for a favorable and lasting result. Results: Annual reevaluations for up to 5 years revealed a functional neovagina with an average length of approximately 11.33 cm, without stenotic aspects, and no granulation tissue formation. All three cases in which this technique was performed reported sexual activity as expected, excellent quality of life, and good psycho-emotional reintegration. It should be noted that two of the three patients also resolved their marital situation. Conclusions: Although the number of patients in this preliminary report is limited, the surgical technique presented is an effective, safe approach with very good anatomical and functional results at the 5-year follow-up. The favorable surgical outcome of these cases also determined the social integration of the patients, solving some ethnic and religious problems. Full article

Background: Uterus transplantation (UTx) is currently the only available treatment for absolute uterine factor infertility. Deceased donors have recently emerged as a valid alternative to living donors for uterus transplantation, with similar results. Methods: We report the first experience in Italy of uterus transplantation from deceased donors. Three uterus transplantations from deceased donors were performed at the Organ Transplant Unit of the University Hospital of Catania, Italy, between August 2020 and January 2022. Results: Two patients underwent UTx due to Mayer–Rokitansky–Küster–Hauser syndrome, while one patient had a previous hysterectomy due to benign disease. The donors’ ages were between 25 and 43 years and the mean cold ischemia time was 18.3 h. The mean age of the recipients was 31.6 years, and the mean recipient surgery duration was 5.3 h, with a mean blood loss of 766.66 mL. Two recipients developed a post-transplant hematoma, which was treated conservatively. No uterus recipient needed a re-operation during the first 30 days after transplantation. No histological signs of acute rejection were detected at the cervical biopsies performed at 1, 3, and 6 months after transplantation. First menstruation occurred in all recipients after 39 ± 12 days after transplantation. One live birth was reported 15 months after UTx. One graft was lost three months after UTx due to graft thrombosis. Conclusions: Uterus transplantation from deceased donors is emerging as a valid alternative to living donors in order to increase the donor pool. Full article

Background: Women with an aplastic uterus (ESHRE/ESGE classification) or Müllerian agenesis (ASRM MAC 2021) might present with functional uterine remnants. Our study aimed to report the clinical course of symptomatic uterine rudiments in adolescents and adults with Mayer–Rokitansky–Küster–Hauser syndrome (MRKHS). Methods: This study involved 20 patients with MRKHS who, between 2012 and 2023, underwent surgery for symptomatic uterine horns at the mean age of 25.2 years in the Division of Gynaecology, Gynaecological and Obstetric Clinical Hospital, Poznan University of Medical Sciences, Poland. The records of the patients were retrospectively analysed. Results: The volume of the uterine horns ranged from 0.8 to 58.3 cm3, and the volume of the endometrial cavity within the horns ranged from 0.03 to 12 cm3, with no significant difference between adolescents and adults (p = 0.36). In five patients (25%), MRKHS was identified during the diagnosis of recurrent pelvic pain at the age of 12.6–14.8 years. In 19 patients, uterine rudiments were removed: unilaterally in 3 patients (16%), bilaterally in 16 patients (84%), and laparoscopically in 89% of cases. In one patient, the horn was preserved (horno-neovaginal anastomosis). Histopathology confirmed the presence of the endometrium in uterine rudiments ipsilateral to the pain location in 75% of cases. Four patients (20%) were diagnosed with endometriosis. Conclusions: Recurrent pelvic pain in patients with MRKHS should prompt the diagnosis of functional uterine rudiments. The resection of symptomatic uterine horns can result in the complete resolution of pain. Patients with endometriosis are at risk of pain recurrence. In some patients strongly desirous of menstruation, horno-neovaginal anastomosis can be cautiously attempted. Full article

Uterus transplantation is the surgical treatment for absolute uterine factor infertility (AUFI), a congenital or acquired condition characterized by the absence of a uterus. More than 80 transplants have been performed worldwide, resulting in more than 30 live births, originating both from living and deceased donors. The collection of published articles on deceased donor uterus transplantations was performed in PubMed and SCOPUS by searching for the terms “Uterus transplantation” AND “deceased donor”; from the 107 articles obtained, only case reports and systematic reviews of deceased donor uterus transplantations and the resulting live births were considered for the present manuscript. The extracted data included the date of surgery (year), country, recipient (age and cause of AUFI) and donor (age and parity) details, outcome of recipient surgery (hysterectomy), and live births (date and gestational age). The search of peer-reviewed publications showed 24 deceased donor uterus transplantations and 12 live births (a birth rate of 66%) with a 25% occurrence of graft loss during follow-up (6 of 24). Among this series, twelve transplants were performed in the USA (seven births), five in the Czech Republic (one birth), three in Italy (one birth), two in Turkey (two births), and two in Brazil (one birth). The median recipient age was 29.8 years (range 21–36), while the median donor age was 36.1 years (range 20–57). Of 24 recipients, 100% were affected by MRKH (Mayer-Rokitanski-Kuster-Hauser) syndrome. Two live births were reported from nulliparous donors. Deceased donor uterus transplantation birth rates are very similar to the living donor rates reported in the literature, but ethical implications could be less important in the first group. It is necessary to register every case in the International Registry for Uterus Transplantation in order to perform a systematic review and comparison with living donor rates. Full article

Vaginal agenesis (VA) is frequently associated with mullerian agenesis. VA treatments include mechanical dilation and surgical vaginoplasty. We created a vaginal expansion sleeve (VES) as a novel device to progressively lengthen the vaginal canal. This study evaluated the histologic effects of the VES on rat vaginal tissue. The VES is a spring-like device made of proprietary woven cylindrical material and flat resin caps. The VESs were constructed as 25–30 mm, pre-contracted springs, which were secured into the vaginas of six Sprague Dawley rats and allowed to re-expand post-surgically. After one week, the VESs were removed, and the vaginas were harvested and measured in length. Test (n = 6) and control (n = 4) formalin-fixed paraffin-embedded tissues were stained with hematoxylin and eosin (H&E), Masson’s trichrome, and anti-Desmin antibodies. The VESs achieved significant vaginal lengthening. The mean vaginal canal length increased from 20.0 ± 2.4 mm to 23.8 ± 1.2 mm after removal of the VESs (n = 6, p < 0.001), a 19% increase. There was a positive correlation between the expander/tension generated in the vagina and the amount of acute and chronic inflammation. H&E staining revealed increased submucosal eosinophilia in five of the six test tissues. One VES sample that was lengthened to 30 mm long showed evidence of lymphocytic and neutrophilic inflammation. Desmin immunostaining and Masson’s trichrome stain revealed a thinner muscularis with more infiltrative fibrous tissue between muscle fibers in the test tissue compared to the control tissue. Although effective, the VES may provoke at least a transient increase in eosinophils consistent with a localized immune reaction during muscularis remodeling. Full article

Chromosome 17q12 deletion syndrome (OMIM #614527) is a rare genetic disorder associated with a heterozygous 1.4–1.5 Mb deletion at chromosome 17q12, leading to a spectrum of clinical manifestations, including kidney abnormalities, neurodevelopmental delay, maturity-onset diabetes of the young type 5 (MODY5), and Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome. We present the case of a 14-year-old Korean female diagnosed with chromosome 17q12 deletion syndrome, confirmed by chromosomal microarray analysis. The patient exhibited MODY5 with pancreatic agenesis, MRKH syndrome, dysmorphic facial features, developmental delay, kidney rotation anomaly, portal vein thrombosis with liver hypoplasia, short stature, and scoliosis. Management involved the initiation of multiple daily insulin injections for diabetes control, gynecological evaluation for MRKH syndrome, and multidisciplinary care for associated complications. This case highlights the complexity and varied organ involvement in chromosome 17q12 deletion syndrome. A comprehensive and multidisciplinary approach is crucial for the management of affected individuals, including regular monitoring, tailored interventions across various medical specialties, and providing psychosocial support.

Uterus transplantation (UTx) is currently the only available treatment for absolute uterine factor infertility. More than 90 uterus transplantations have been performed worldwide, mostly from living donors. Living-donor (LD) UTx is a challenging surgical procedure since it poses ethical issues, and it is a high-risk and invasive surgery with higher hysterectomy-related risks compared to conventional hysterectomy. A total of 59 living-donor hysterectomies have been reported in the literature, including 35 performed with a laparotomic approach, 20 with a robotic approach and 4 with a laparoscopic approach. The mean donor age was 45.6 ± 9.1 years, and 22 were unrelated with the recipients, 34 were emotionally related (27 mothers, 5 sisters, 2 mother’s sisters). The mean recipient age was 28.8 ± 4.5 years. Mayer–Rokitansky–Küster–Hauser syndrome was the most common indication for uterus transplant. Robotic living-donor hysterectomy had the longest operative time but resulted in a lower blood loss and postoperative stay compared to laparotomic and laparoscopic approaches. Twenty-nine births from LD-UTx have been reported, four after robotic living-donor hysterectomy and twenty-five after a laparotomic procedure. UTx is now an effective treatment for women with UFI. While living-donor UTx in some cases may be considered an experimental procedure, it offers the extraordinary possibility to give women the opportunity to have a pregnancy. Many efforts should be made to reduce the potential risks for donors, including the use of mini-invasive techniques, and the efficacy of UTx in the recipients, giving the potential harm of immunosuppression in a recipient of a non-life-saving organ.

The Mayer–Rokitansky–Küster–Hauser syndrome is characterized by aplasia of the uterus and upper two-thirds of the vagina. While it can appear as an isolated genital malformation, it is often associated with extragenital abnormalities, with little still known about the pathogenetic background. To provide an overview of associated malformations and syndromes as well as to examine possible ties between the rudimentary tissue and patient characteristics, we analyzed a cohort of 469 patients with MRKHS as well as 298 uterine rudiments removed during surgery. A total of 165 of our patients (35.2%) had associated malformations (MRKHS type II). Renal defects were the most common associated malformation followed by skeletal abnormalities. Several patients had atypical associated malformations or combined syndromes. Uterine rudiments were rarer in patients with associated malformations than in patients without them. Rudiment size ranged from 0.3 cm3 to 184.3 cm3 with a mean value of 7.9 cm3. Importantly, MRKHS subtype or concomitant malformations were associated with a different frequency of uterine tissue as well as a different rudiment size and incidence of endometrial tissue, thereby indicating a clear heterogeneity of the phenotype. Further research into the associated molecular pathways and potential differences between MRKHS subtypes is needed. Full article

Infertility affects around 1 in 5 couples in the world. Congenital absence of the uterus results in absolute infertility in females. Müllerian agenesis is the nondevelopment of the uterus. Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome is a condition of uterovaginal agenesis in the presence of normal ovaries and the 46 XX Karyotype. With advancements in reproductive techniques, women with MA having biological offspring is possible. The exact etiology of MA is unknown, although several genes and mechanisms affect the development of Müllerian ducts. Through this systematic review of the available literature, we searched for the genetic basis of MA. The aims included identification of the genes, chromosomal locations, changes responsible for MA, and fertility options, in order to offer proper management and counseling to these women with MA. A total of 85 studies were identified through searches. Most of the studies identified multiple genes at various locations, although the commonest involved chromosomes 1, 17, and 22. There is also conflicting evidence of the involvement of various candidate genes in the studies. The etiology of MA seems to be multifactorial and complex, involving multiple genes and mechanisms including various mutations and mosaicism. Full article

Uterus-related infertility affects 3–5% of all young women, including Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, hysterectomy, or severe Asherman syndrome. For these women with uterus-related infertility, uterus transplantation is now a viable option. We performed the first surgically successful uterus transplant in September 2011. The Donor was a 22-year-old nulliparous woman. After five failed pregnancy attempts (pregnancy losses), ET attempts were discontinued in the first case, and a search for underlying etiology was performed, including static and dynamic imaging studies. Perfusion computed tomography revealed an obstructed blood outflow, particularly in the left anterolateral part of the uterus. In order to correct blood flow obstruction, a revision surgery was planned. By laparotomy, a saphenous vein graft was anastomosed between the left utero-ovarian and left ovarian vein. Perfusion computed tomography performed after the revision surgery confirmed the resolution of venous congestion and a decrease in uterine volume as well. Following surgical intervention, the patient was able to conceive after the first embryo transfer attempt. The baby was delivered with cesarean section at 28 weeks’ gestation due to intrauterine growth restriction and abnormal Doppler ultrasonography findings. Following this case, our team performed the second uterus transplantation in July 2021. The recipient was a 32-year-old female with MRKH syndrome, and the donor was a 37-year-old multiparous braindead woman due to intracranial bleeding. After the transplant surgery, the second patient experienced menstrual bleeding six weeks after the operation. Seven months after the transplant, in the first ET attempt, pregnancy was achieved, and she delivered a healthy baby at 29 weeks of pregnancy. Uterus transplantation from a deceased donor is a feasible option for treating uterus-related infertility. When confronted with recurrent pregnancy losses, vascular revision surgery via arterial or venous supercharging could be an option in order to deal with focal underperfused areas defined by imaging studies.

Vaginal atresia is seen in genetic disorders such as Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome, which can cause significant sexual dysfunction. Current treatments include surgical reconstruction or mechanical dilation of the vaginal canal. Mechanical dilation requires patients to be highly motivated and compliant while surgical reconstruction has high rates of complications. This study evaluated a novel vaginal expansion sleeve (VES) method as an alternative treatment for vaginal atresia. The proprietary cylindrical VES is a spring-like device consisting of polyethylene terephthalate helicoid trusses capped at each end with a fixed diameter resin cap for fixation within tissues. Following the development of the VES and mechanical characterization of the force–length relationships within the device, we deployed the VES in Sprague Dawley rat vaginas anchored with nonabsorbable sutures. We measured the VES length–tension relationships and post-implant vaginal canal expansion ex vivo. Vaginal histology was examined before and after implantation of the VES devices. Testing of 30 mm sleeves without caps resulted in an expansion force of 11.7 ± 3.4 N and 2.0 ± 0.1 N at 50% and 40%, respectively. The implanted 20 mm VES resulted in 5.36 mm ± 1.18 expansion of the vaginal canal, a 32.5 ± 23.6% increase (p = 0.004, Student t test). Histological evaluation of the VES implanted tissue showed a significant thinning of the vaginal wall when the VES was implanted. The novel VES device resulted in a significant expansion of the vaginal canal ex vivo. The VES device represents a unique alternative to traditional mechanical dilation therapy in the treatment of vaginal atresia and represents a useful platform for the mechanical distension of hollow compartments, which avoids reconstructive surgeries and progressive dilator approaches.

Congenital Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a Mullerian-duct anomaly that is characterized by agenesis of the uterus and upper part of the vagina. Uterus remnants of varying sizes can often be found. Although a functional uterus is missing, the existence of endometriosis in this patient group has been described in the literature; however, a histopathological comparison of the characteristics of the endometrium within the uterus remnants versus endometriotic peritoneal lesions in the same patient is lacking. Moreover, the characteristics of endometriotic tissue in patients with MRKH syndrome have not been correlated with those of patients with endometriosis without Mullerian anomaly. Patients who underwent laparoscopic neovagina creation with the removal of uterus remnants and possible resection of endometriotic lesions between 2010 and 2022 at the Department of Women’s health of the University of Tuebingen were included in our study. Uterine remnants and endometriotic tissue were evaluated via histopathology and immunohistochemistry and were compared to endometriotic samples from patients without Mullerian anomaly. Endometriosis was detected in nine MRKH patients; in four patients, endometrial remnants could be sufficiently compared to endometriotic lesions. All samples exhibited increased expression of hormonal receptors. In two patients, Ki67 proliferation index was significantly increased in peritoneal endometriotic lesions compared with the endometrium of the remnants. In contrast, endometrium and endometriotic lesions of endometriosis patients did not exhibit any differences in the Ki67 proliferation index. Our results demonstrate distinctive immunohistochemical variability between uterine remnants and endometriotic lesions in patients with MRKH syndrome compared with patients with endometriosis, indicating a possible explanation model of the yet-unknown etiology of endometriosis. For confirmation, investigation of a broader patient collective is necessary. Full article

To identify potential genetic causes for Mayer-Rokitansky-Küster-Hauser syndrome (MRKH), we analyzed blood and rudimentary uterine tissue of 5 MRKH discordant monozygotic twin pairs. Assuming that a variant solely identified in the affected twin or affected tissue could cause the phenotype, we identified a mosaic variant in ACTR3B with high allele frequency in the affected tissue, low allele frequency in the blood of the affected twin, and almost absent in blood of the unaffected twin. Focusing on MRKH candidate genes, we detected a pathogenic variant in GREB1L in one twin pair and their unaffected mother showing a reduced phenotypic penetrance. Furthermore, two variants of unknown clinical significance in PAX8 and WNT9B were identified. In addition, we conducted transcriptome analysis of affected tissue and observed perturbations largely similar to those in sporadic cases. These shared transcriptional changes were enriched for terms associated with estrogen and its receptors pointing at a role of estrogen in MRKH pathology. Our genome sequencing approach of blood and uterine tissue of discordant twins is the most extensive study performed on twins discordant for MRKH so far. As no clear pathogenic differences were detected, research to evaluate other regulatory layers are required to better understand the complex etiology of MRKH. Full article

Background: The apparent absence of a uterus upon imaging women with primary amenorrhea appears to lead to a high risk of misdiagnosis, which will lead to significant mental distress in patients. Case: Three young females with primary amenorrhea were referred with a diagnosis of Mayer–Rokitansky–Kuster–Hauser syndrome based on radiological findings of an apparently absent uterus. In two patients, the absence of the uterus could be confirmed, but with various diagnoses. The other patient had a normal but unstimulated uterus due to her hypoestrogenic state. Summary and Conclusion: The presented cases illustrate the broad differential diagnoses and the specific pitfalls of primary amenorrhea with an apparently absent uterus upon imaging. A well-established diagnosis was only possible through a thorough correlation of imaging findings with clinical history, biochemical findings and physical examination. Full article
