Common pathogenesis for sirenomelia, OEIS complex, limb-body wall defect, and other malformations of caudal structures.

Decades of clinical, pathological, and epidemiological study and the recent application of advanced microarray and gene sequencing technologies have led to an understanding of the causes and pathogenesis of most recognized patterns of malformation. Still, there remain a number of patterns of malformation whose pathogenesis has not been established. Six such patterns of malformation are sirenomelia, VACTERL association, OEIS complex, limb-body wall defect (LBWD), urorectal septum malformation (URSM) sequence, and MURCS association, all of which predominantly affect caudal structures. On the basis of the overlap of the component malformations, the co-occurrence in individual fetuses, and the findings on fetal examination, a common pathogenesis is proposed for these patterns of malformation. The presence of a single artery in the umbilical cord provides a visible clue to the pathogenesis of all cases of sirenomelia and 30%-50% of cases of VACTERL association, OEIS complex, URSM sequence, and LBWD. The single artery is formed by a coalescence of arteries that supply the yolk sac, arises from the descending aorta high in the abdominal cavity, and redirects blood flow from the developing caudal structures of the embryo to the placenta. This phenomenon during embryogenesis is termed vitelline vascular steal.

Modified Vecchietti vaginoplasty using self-made single-port laparoscopy in Mayer-Rokitansky-Küster-Hauser syndrome.

OBJECTIVE: To introduce the minimally invasive Vecchietti procedure based on single-port laparoscopy with self-made surgical instruments for the surgical management of Mayer-Rokitansky-Küster-Hauser syndrome (MRKH). DESIGN: Surgical video article. The approval of the Institutional Review Board and written consent from the patient were obtained. SETTING: University hospital. PATIENT(S): A 22-year-old woman presented with primary amenorrhea and inability to participate in penetrative sexual intercourse. A gynecological examination revealed a phenotypically normal vulva and absence of the vagina. A normal 46,XX karyotype was expressed. Magnetic resonance imaging and ultrasonic imaging of the abdomen and pelvis indicated that the ovaries were normal in size and there was vaginal agenesis with rudimentary uterus. No other congenital malformations were present. INTERVENTION(S): The modified Vecchietti procedure involved a transvaginal operation and laparoscopic surgery. The epidural catheter was stretched and made into two wires that were tucked into the core of the Veress needle and then folded into four strings for perineal puncture. A transverse incision of about 3 cm was made in the center of the navel, layer by layer into the abdomen, and placed in a self-made single port (made of a small wound protector and an 8-inch glove), introducing the laparoscope. Under laparoscopic surveillance, the Veress needle was inserted through the vesicorectal space guided by the index finger, which was placed in the rectum. The epidural catheter was pumped from the core into the abdominal cavity under laparoscopy. Subsequently, cystoscopy was performed to ensure that no bladder perforation occurred during the needle insertion. The ball-shaped acrylic device and the two rubber stoppers were attached to the epidural catheter of the vulva. An epidural puncture needle with wire perforated the peritoneum through McBurney's point and the opposite McBurney's point, pulling the epidural catheter out of the abdominal cavity. The epidural catheter was curled around the gauze rolls until the ball-shaped device could be accommodated into the newly created cavity at a sufficient depth. After the surgery, the top of neovagina was lifted about 1 cm every day by tightening gauze rolls to increase the traction, until a neovagina 9 cm long was achieved. MAIN OUTCOME MEASURE(S): The clinical and anatomical data such as the operative time, intraoperative bleeding, duration of hospitalization, and measurement of the final length of the newly created canal 30 days after surgery and 3 months after surgery. RESULT(S): The operative time was 30 minutes, and the intraoperative blood loss was 10 mL. The duration of hospitalization was 10 days. Before discharge, the vaginal depth was 9 cm at 5 days after the surgery, and the self-made traction system was removed. A plastic mold was then inserted using povidone-iodine. The vaginal dilator had to be worn day and night. The patient was advised to sit at the corner of a hard bed or chair from time to time to enhance the dilated effect of the vaginal mold. Three months after the surgery, it could be worn each night until regular sexual intercourse was initiated. The canal length 30 days and 3 months after the surgery was nearly 9 cm. CONCLUSION(S): The modified Vecchietti vaginoplasty is a simple, safe, cost-effective, and minimally invasive procedure, offering an anatomic and functional neovagina for MRKH patients.

[Iatrogenic urethral coitus]. / Iatrogene urethrale coïtus.

This case discussion on urethral coitus in Mayer-Rokitansky-Küster-Hauser syndrome shows that this rare syndrome can have major physical and psychological consequences. Further consideration shows that a lack of common sense and a lack of action concerning sexual history-taking and careful vulvar examination is the reason that an iatrogenic sexual problem arose in this case. This was not the result of the initial denial of a rare diagnosis. Both attention to these aspects during training and supervision are necessary, since other disorders and medical treatments can also have a negative impact on sexuality.

Sexual function and quality of life after the creation of a neovagina in women with Mayer-Rokitansky-Küster-Hauser syndrome: comparison of vaginal dilation and surgical procedures.

OBJECTIVE: To compare sexual function and outcomes of quality of life of patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome after vaginal dilation and surgical procedures. STUDY DESIGN: Cross-sectional study from January 2019 to June 2019. SETTING: Tertiary teaching hospital. PATIENT(S): Women with MRKH syndrome treated with vaginal dilation (n = 88) or surgical procedures (n = 45). INTERVENTION: WeChat-based questionnaires were distributed to every group member in our MRKH support group. MAIN OUTCOME MEASURE(S): Sexual functional were assessed by means of the Female Sexual Function Index (FSFI). Outcomes of quality of life were assessed by means of the 12-item World Health Organization Disability Assessment Schedule 2 (WHODAS2). Vaginal length was defined as the maximum depth of the placement of the vaginal mold. RESULT(S): The FSFI scores were similar between the dilation (24.49 ± 4.51) and surgery (23.79 ± 3.57) groups. Except for the higher orgasm score in the dilation group (9.96 ± 3.60 vs. 8.20 ± 2.67), the other dimensions of the FSFI were not significantly different between the groups. No significant differences were found in the WHODAS2 scores between the dilation group (median 8.33 [interquartile range 4.17-15.62]) and the surgery group (6.25 [2.08-14.58]). However, the vaginal length was significantly shorter in the dilation group (6.5 ± 2.04 cm) than in the surgery group (8.1 ± 1.59 cm). CONCLUSION(S): Although the vaginal length was shorter in the dilation therapy group than in the surgical therapy group, sexual function and quality of life were similar between these two groups. Vaginal dilation should be proposed as the first-line therapy for MRKH patients.

Mayer-Rokitansky-Küster-Hauser syndrome - case studies, methods of treatment and the future prospects of human uterus transplantation.

OBJECTIVE: We aimed to present patients with the Mayer-Rokitansky-Küster-Hauser syndrome (MRKH) coming from one center and presenting all the possibilities of its treatment, at the forefront with the uterine transplantation. PATIENTS AND METHODS: The presented work is an example of different types of MRKH syndrome diagnosed in 25 women who were diagnosed in the Department of Gynecological Endocrinology due to the primary amenorrhea from 01/2001 to 06/2018. RESULTS: Patients suffering from MRKH syndrome are capable of having genetic offspring but are unable to give birth to their own child, due to an absence of the uterus, blindly terminated vagina, and normal ovaries. Patients suffering from this syndrome have the opportunity to receive treatment in accordance with their current needs. However, there are many medical, technical, and ethical limitations in achieving the most important therapeutic target: uterine transplantation and childbirth. CONCLUSIONS: Until a few years ago, patients with an absolute uterine factor of infertility, including women with MRKH syndrome, had a real choice of only two equally controversial options giving a chance for motherhood - surrogacy and adoption. However, modern transplantation has shown that a third option - a uterine transplant - exists and is available.

Sexual functioning, sexual esteem, genital self-image and psychological and relational functioning in women with Mayer-Rokitansky-Küster-Hauser syndrome: a case-control study.

STUDY QUESTION: Do sexual functioning, sexual esteem, genital self-image and psychological and relational functioning in women with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome differ from a comparison group of women without the condition? SUMMARY ANSWER: In comparison to controls, women with MRKH with a non-surgically or surgically created neovagina did not differ in psychological and relational functioning but reported lower sexual esteem and more negative genital self-image, intercourse-related pain, clinically relevant sexual distress and sexual dysfunction, with sexual esteem levels strongly associated with sexual distress and sexual dysfunction. WHAT IS KNOWN ALREADY: Studies on sexual functioning measured with standardized questionnaires in women with MRKH syndrome compared with women without the condition have yielded contradictory results. Factors associated with sexual functioning in this patient population have rarely been investigated. STUDY DESIGN, SIZE, DURATION: Between November 2015 and May 2017, 54 women with MRKH syndrome with a neovagina and 79 age-matched healthy women without the condition were enrolled in this case-control study. PARTICIPANTS/MATERIALS, SETTING, METHODS: All participants had to be at least 18-years old and had to live in a steady heterosexual relationship. Women with MRKH syndrome were asked to participate by their (former) gynecologists at three university hospitals and by MRKH peer support group. Controls were recruited via advertisement in local newspapers and social media. Standardized questionnaires were administered to assess sexual functioning, sexual esteem, genital self-image and psychological and relational functioning. MAIN RESULTS AND THE ROLE OF CHANCE: Women with MRKH syndrome with a surgically or non-surgically created neovagina reported significantly more pain during intercourse (P < 0.05, d = 0.5), but did not differ in overall sexual functioning from control women. More women with MRKH syndrome reported clinically relevant sexuality-related distress (P < 0.05, odds ratio (OR): 2.756, 95% CI 1.219-6.232) and suffered a sexual dysfunction (P < 0.05, OR: 2.654, 95% CI: 1.088-6.471) in comparison with controls. MRKH women scored significantly lower on the sexual esteem scale (SES) (P < 0.01, d = 0.5) and the female genital self-image scale (FGSIS) (P < 0.01, d = 0.6) than controls. No significant differences were found between the two groups regarding psychological distress, anxiety and depression, global self-esteem and relational dissatisfaction. Sexual esteem was significantly associated with the presence of clinically relevant sexual distress (ß = 0.455, P = 0.001) and suffering a sexual dysfunction (ß = 0.554, P = 0.001) and explained, respectively, 40% and 28% of the variance. LIMITATIONS, REASONS FOR CAUTION: Given the nature of the study focusing on sexual functioning, a potential selection bias cannot be excluded. It is possible that those women with the most severe sexual and/or psychological disturbances did or did not choose to participate in our study. WIDER IMPLICATIONS OF THE FINDINGS: The study results add new data to the very limited knowledge about psychosexual functioning of women with MRKH syndrome and are of importance for more adequate counseling and treatment of these women. STUDY FUNDING/COMPETING INTEREST(S): The research was financially supported by the Dutch Scientific Society of Sexology (Nederlandse wetenschappelijke Vereniging Voor Seksuologie). The funding was unrestricted, and there was no involvement in the conduct of the research. There are no conflicts of interest to declare.

Neovagina creation methods and their potential impact on subsequent uterus transplantation: a review.

Congenital uterovaginal aplasia commonly occurs in Mayer-Rokitansky-Küster-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. TWEETABLE ABSTRACT: This review discusses the main advantages and disadvantages of neovagina creation methods with regard to subsequent uterus transplantation.

Zinner and Mayer-Rokitansky-Küster-Hauser syndromes: when unilateral renal agenesis meets genital anomalies.

Congenital unilateral renal agenesis is a relatively frequent condition at birth diagnosed mostly incidentally. Despite the excellent prognosis, unilateral renal agenesis is associated with an increased risk of other structural abnormalities, including genital malformations. The authors present two cases of asymptomatic adolescents with known congenital unilateral renal agenesis and associated genital malformations solely diagnosed during puberty-a man with Zinner syndrome and a female with Mayer-Rokitansky-Küster-Hauser syndrome.

Urogynecological and Sexual Functions after Vecchietti Reconstructive Surgery.

HYPOTHESIS/AIMS OF STUDY: Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is the second most common cause of primary amenorrhea. The ESHRE/ESGE categorizes this disorder within the class 5 uterine malformation of the female genital tract anomalies. It is characterized by congenital absence of the uterus, cervix, and upper part of the vagina in otherwise phenotypically normal 46XX females. These patients have normal ovaries, biphasic ovarian cycle, and female psychosexual identification. Laparoscopic Vecchietti's operation-surgical method in which the vagina increases in size by gradually applying traction to the vaginal vault-is one of the methods used to treat MRKH. The aim of this study was to establish the urogynecological and sexual functions after Vecchietti's operation. STUDY DESIGN MATERIALS AND METHODS: Fifteen patients with MRKHS who underwent laparoscopic Vecchietti's operation were included. A control group of 15 age-matched, childless, sexually active women were examined during the same period. All patients underwent the basic evaluation of anatomical outcomes. Sexual outcomes were established by the Polish validated Female Sexual Function Index (FSFI) questionnaire. Continence status was assessed by Polish validated Urinary Distress Inventory (UDI-6) and the Incontinence Impact Questionnaire (IIQ-7). RESULTS: Mean age of MRKH group was 22.06±5.13 yrs. Mean follow-up after surgery was 8.02±3.43 yrs. Mean age of women from control group was 22.4±4.35. Mean FSFI scores show good quality of sexual life in both groups. UDI-6 scores showed that patients after Vecchietti surgery have urogynecological problems significantly more often than healthy women do. Based on the IIQ-7, it is evident that one patient from the MRKH group (6,6%) suffers from stress urinary incontinence and the rest (20%) have rather irritative problems with the functioning of the lower urinary tract. CONCLUSION: Quality of sexual life after the Vecchietti's operation in long-term follow-up does not differ from that of healthy women, but these patients suffer more frequent from urogynecological complaints. The trial is registered with NCT03809819.

Pubertal Development and Pregnancy Outcomes in 46,XX Patients With Nonclassic Lipoid Congenital Adrenal Hyperplasia.

CONTEXT: Lipoid congenital adrenal hyperplasia (LCAH) is characterized by a disorder of steroidogenesis in both adrenal glands and gonads. 46,XX patients with classic LCAH usually have thelarche and menarche but show anovulatory menstruations and subsequent premature menopause. Only three patients with classic LCAH have been reported to successfully achieve delivery with the aid of assisted reproductive therapies for conception and progesterone replacement therapy during early pregnancy. In contrast, pubertal development and pregnancy outcomes in patients with nonclassic LCAH have not been fully elucidated. CASE DESCRIPTION: We report four Japanese women who had a diagnosis of primary adrenal insufficiency during infancy or childhood and carried compound heterozygous STAR mutations (p.Gln258* and p.Arg188His, p.Gln258* and p.Met225Thr, and p.Gln258* and p.Arg272Cys). In all four patients, thelarche and menarche spontaneously occurred from 10 to 11 years of age and from 12 to 14 years of age, respectively. Subsequently, their menstruation cycles were regular at almost 1-month intervals. Patient 1 conceived naturally twice, and patient 2 conceived with the use of clomiphene citrate for ovulation induction. These two patients maintained the pregnancies without progesterone replacement therapy and successfully delivered children. CONCLUSION: Patients with nonclassic LCAH maintain ovarian function, which enables normal pubertal development and a successful pregnancy outcome without progesterone replacement therapy.

Sexual response in women with Mayer-Rokitansky-Küster-Hauser syndrome with a nonsurgical neovagina.

BACKGROUND: Sexual dysfunction is prevalent in women with Mayer-Rokitansky-Küster-Hauser syndrome after the creation of a neovagina. Insight into the physiologic response of the neovagina during sexual arousal is lacking, although this would help in the understanding of sexual function of these patients. The physiologic sexual response of the vagina can be measured objectively by vaginal photoplethysmography to assess vaginal blood flow. OBJECTIVE: Testing whether the physiologic and subjective sexual response in women with Mayer-Rokitansky-Küster-Hauser syndrome with a neovagina differs from the response in women with a natal vagina. STUDY DESIGN: Vaginal blood flow (vaginal pulse amplitude) and subjective sexual responses during neutral and erotic film viewing were assessed in premenopausal women with Mayer-Rokitansky-Küster-Hauser syndrome with a nonsurgically created neovagina (n=15) and were compared with responses of an age-matched control group (n=21). RESULTS: All women with Mayer-Rokitansky-Küster-Hauser syndrome had created their neovagina themselves by dilation. Women with Mayer-Rokitansky-Küster-Hauser syndrome showed a significantly smaller vaginal pulse amplitude compared with control subjects during neutral film viewing (P=.002). In both groups, vaginal pulse amplitude increased significantly during erotic film viewing, but this increase was significantly smaller in the Mayer-Rokitansky-Küster-Hauser syndrome group (P<.005). Levels of subjective sexual arousal did not significantly differ between the 2 groups (P>.2). CONCLUSION: Women with Mayer-Rokitansky-Küster-Hauser syndrome with a nonsurgically created neovagina showed a weaker vaginal blood flow response during visual sexual stimulation and poorer basal blood flow compared with control subjects. The differences in vaginal blood flow may be related to less vascularization and innervation of the neovagina compared with the natal vagina. The weaker vaginal sexual response can play a role in sexual dysfunction; however, despite the weaker vaginal response, women with Mayer-Rokitansky-Küster-Hauser syndrome did not differ in their level of subjective sexual arousal. Future studies may compare vaginal blood flow and subjective sexual response of women with Mayer-Rokitansky-Küster-Hauser syndrome with nonsurgically and surgically created vaginas.

Genetics of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, also referred to as Müllerian agenesis, is the second most common cause of primary amenorrhea. It is characterized by congenital absence of the uterus, cervix, and the upper part of the vagina in otherwise phenotypically normal 46,XX females. MRKH syndrome has an incidence of about 1 in 4,500-5,000 newborn females and it is generally divided into two subtypes: MRKH type 1, in which only the upper vagina, cervix and the uterus are affected, and MRKH type 2, which is associated with additional malformations generally affecting the renal and skeletal systems, and also includes MURCS (MÜllerian Renal Cervical Somite) characterized by cervico-thoracic defects. MRKH syndrome is mainly sporadic; however, familial cases have been described indicating that, at least in a subset of patients, MRKH may be an inherited disorder. The syndrome appears to demonstrate an autosomal dominant inheritance pattern, with incomplete penetrance and variable expressivity. The etiology of MRKH syndrome is still largely unknown, probably because of its intrinsic heterogeneity. Several candidate causative genes have been investigated, but to date only WNT4 has been associated with MRKH with hyperandrogenism. This review summarizes and discusses the clinical features and details progress to date in understanding the genetics of MRKH syndrome.

Congenital malformations and other comorbidities in 125 women with Mayer-Rokitansky-Küster-Hauser syndrome.

OBJECTIVE: To describe congenital malformations and coexisting disorders occurring in 125 Polish women with Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS). The syndrome is defined as uterovaginal aplasia in female with normal 46,XX karyotype. STUDY DESIGN: A retrospective analysis of the clinical data of MRKHS patients diagnosed or treated at the Gynecology and Obstetrics Clinical Hospital of Poznan University of Medical Sciences between 2010 and 2015. RESULTS: Sixty-eight patients (54,4%) were found to have one or more coexisting anomalies. Thirty-eight patients (55,9% of cases with concomitant malformations, 30,4% of the entire study group) had coexisting anomalies of at least two organ systems. The most frequent extragenital malformations were skeletal anomalies found in 40 patients (32%) and renal anomalies found in 36 patients (28,8%). Fifty-seven patients (45,6%) were diagnosed with typical form (type 1) and 16 (12,8%) with the atypical form (type 2) of MRKHS. In the other 52 patients (41,6%) we diagnosed MURCS association. Five of our patients (4%) had karyotype abnormalities. CONCLUSIONS: Our study confirms complexity and clinical heterogeneity of MRKHS. Concomitant congenital malformations are present in about half of MRKHS women. A significant proportion of patients have coexisting anomalies of at least two organ systems. The most common coexisting findings are musculoskeletal and renal abnormalities. Chromosomal aberrations may be present in patients with either typical or atypical form of MRKHS.

Phenotypic and clinical aspects of Mayer-Rokitansky-Küster-Hauser syndrome in a Chinese population: an analysis of 594 patients.

OBJECTIVE: To analyze the phenotypic and clinical aspects of Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. DESIGN: Cross-sectional study. SETTING: University hospital. PATIENT(S): Five hundred and ninety-four patients with MRKH syndrome. INTERVENTION(S): Clinical examination, abdominal or perineal/rectal ultrasound, magnetic resonance imaging, hormonal profile, karyotype, and laparoscopy. MAIN OUTCOME MEASURE(S): Clinicopathologic data, VCUAM (vagina cervix uterus adnex-associated malformation) classification, types with cycle phase, and karyotype. RESULT(S): We identified associated malformations in 43 out of 594 (7.2%) cases of MRKH. The 594 patients could be grouped into hormone phases: 53.7% follicular, 35.2% luteal, and 11.1% ovulatory. The major karyotype of MRKH patients was 46,XX; abnormal karyotypes were found in two cases. CONCLUSION(S): A lower proportion of associated malformations were found when compared with those provided in the current literature. Renal anomalies were the most frequent associated malformations, and most of the patients presented with a normal karyotype. Given the large cohort of this study, the lower malformation rates might be related to geographic or referral patterns, so further investigation is warranted.

Laparoscopic Davydov Procedure for the Creation of a Neovagina in Patients with Mayer-Rokitansky-Kuster-Hauser Syndrome: Analysis of 7 Cases.

OBJECTIVE: Several surgical techniques have been described for creating a neovagina in patients with Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome, however as yet there is no standardized treatment. The aim of this report is to assess anatomic and functional outcomes after the laparoscopic Davydov procedure for the creation of a neovagina in patients with MRKH syndrome. METHODS: Seven patients with MRKH syndrome underwent the laparoscopic Davydov technique from January 2005 to August 2010. The anatomic and functional results were evaluated after 3, 6, 12, 24, 36, 48, and 60 months. RESULTS: The surgical procedure was performed with no major complications except in one case in which an intraoperative bladder injury occurred and was successfully corrected. The mean duration of surgery was 162.9 minutes (range, 120-230 min). Mean lengths/widths (cm) of the neovagina were 6.4/2.6, 6.5/2.5, 6.5/2.8, 6.4/2.8, 7.1/2.8, and 7.2/2.8 at 3, 6,12, 24, 36, 48, and 60 postoperative months, respectively. CONCLUSION: The laparoscopic Davydov procedure seems to be a safe and effective surgical treatment for patients with MRKH syndrome if postoperative intermittent self dilation was done.

One uterus bridging three generations: first live birth after mother-to-daughter uterus transplantation.

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. DESIGN: Part of an observational study. SETTING: University teaching hospital. 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. CLINICAL TRIAL REGISTRATION: NCT01844362.

Disorders of Sex Development with Testicular Differentiation in SRY-Negative 46,XX Individuals: Clinical and Genetic Aspects.

Virilisation of the XX foetus is the result of androgen excess, resulting most frequently from congenital adrenal hyperplasia in individuals with typical ovarian differentiation. In rare cases, 46,XX gonads may differentiate into testes, a condition known as 46,XX testicular disorders of sex development (DSD), or give rise to the coexistence of ovarian and testicular tissue, a condition known as 46,XX ovotesticular DSD. Testicular tissue differentiation may be due to the translocation of SRY to the X chromosome or an autosome. In the absence of SRY, overexpression of other pro-testis genes, e.g. SOX family genes, or failure of pro-ovarian/anti-testis genes, such as WNT4 and RSPO1, may underlie the development of testicular tissue. Recent experimental and clinical evidence giving insight into SRY-negative 46,XX testicular or ovotesticular DSD is discussed.

[Mayer-Rokitansky-Küster-Hauser syndrome: two cases report]. / Síndrome de Mayer-Rokitansky-Küster-Hauser. Reporte de dos casos.

Agenesia of the Müllerian ducts is a low-frequency congenital disease but with devastating effects on women's reproductive health. In this paper we present two cases of women affected by Mayer-Rokitansky-Küster-Hauser syndrome (MRKH). First case was a 17-year-old woman with aplasia of the upper vagina and absence of uterus. No other defects were found and was classified as type 1-MRKH. Second case was 18-year-old woman with absence of uterus, escoliosis and polycystic ovary syndrome, classified as type II-MRKH. Patients were seen at the Hospital with primary amenorrhea and fully developed secondary sexual characteristics. A clinical follow-up protocol, including the use of high-resolution image studies was used for diagnosis. Diagnostic procedures and current medical approaches to the treatment of MRKH are discussed, including psychological advisory, surgical procedures and new tissue-engineering techniques.
