Abstract
Guidelines for the investigation and management of recurrent pregnancy loss (RPL) have been developed in Europe, USA and UK, but there is currently no Australasian guideline. The Australasian Certificate of Reproductive Endocrinology and Infertility Consensus Expert Panel on Trial Evidence group has prepared a two-part guideline to provide guidance on the management of RPL. In Part I chromosomal, anatomical, and endocrine factors are outlined along with relevant recommendations for clinical management, levels of evidence and grades of consensus. In Part II thrombophilia, autoimmune factors, infective, inflammatory, and endometrial causes, environmental and lifestyle factors, male factor and unexplained causes will be outlined.

[PMID: 38858283 DOI: 10.1007/s10528-024-10857-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Accepted: 06/03/2024] [Indexed: 06/12/2024]
Abstract
Related studies have pointed out that Killer immunoglobulin-like receptor 2DL4 (KIR2DL4) was associated with vascular remodeling in early pregnancy, and it might play an important role in immunity. In this study, recurrent implantation failure (RIF)-related GSE58144 dataset was extracted from the Gene Expression Omnibus (GEO) database. Firstly, the immune micro-environment analyses were conducted to analyze the pathogenesis of KIR2DL4 in RIF. Then, the gene set enrichment analysis (GSEA) was performed to investigate the function of KIR2DL4. Moreover, the TF-mRNA-miRNA and the co-expression networks were constructed to reveal the potential regulation of KIR2DL4. Furthermore, the genes that were associated with KIR2DL4 and differentially expressed in RIF were obtained and defined as key genes, and the functions of these genes were further explored. KIR2DL4 could be used for clinical diagnosis of RIF, and it was correlated with the changes in the immune micro-environment in RIF. From the perspective of function, KIR2DL4 was associated with complement and coagulation cascades, natural killer cell-mediated cytotoxicity, etc. Moreover, the TF-mRNA-miRNA regulatory network was constructed with KIR2DL4, 9 TFs, and 29 miRNAs. Furthermore, KIR2DL4, ACSM1, IL2RB, and PTPN11 were screened as key genes, which were associated with immune-related functions. This study deeply analyzed the function of KIR2DL4 and its role in RIF, and we found that STAT1 might up-regulate KIR2DL4 by INF-γ/JAK2/STAT1 signaling pathway. Besides, over-expressed KIR2DL4 in the mid-luteal endometrium might influence embryo implantation by affecting the embryo implantation microenvironment, which might help deepen the understanding of the molecular mechanism of RIF.

Mandelbaum RS, Anderson ZS, Masjedi AD, Violette CJ, McGough AM, Doody KA, Guner JZ, Quinn MM, Paulson RJ, Ouzounian JG, Matsuo K. Obstetric outcomes of women with congenital uterine anomalies in the United States. Am J Obstet Gynecol MFM 2024; 6:101396. [PMID: 38866133 DOI: 10.1016/j.ajogmf.2024.101396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2024] [Revised: 04/29/2024] [Accepted: 05/28/2024] [Indexed: 06/14/2024]
Abstract
BACKGROUND Due to the rarity, congenital uterine anomaly type-specific evaluation of pregnant women has been relatively understudied. OBJECTIVE To describe national-level obstetric outcomes in women with congenital uterine anomalies. STUDY DESIGN This cross-sectional study queried the Healthcare Cost and Utilization Project's Nationwide Inpatient Sample. Pregnant women with diagnosis of congenital uterine anomalies who had hospital delivery between 2016 and 2019 were examined. The World Health Organization's International Classification of Disease, 10th revision coding was used to delineate type of congenital uterine anomaly, diagnoses, and procedures performed during the index admission. Primary outcomes included pregnancy outcome, which was classified as full-term live birth, preterm live birth, abortion/stillbirth, or ectopic pregnancy. Secondary outcomes included obstetric comorbidities and severe maternal mortality, which were compared between different subtypes of congenital uterine anomalies with multivariable logistic regression model. RESULTS A total of 50,180 pregnant women with congenital uterine anomalies were identified. Bicornuate was the most common subtype (73.5%), followed by arcuate (13.5%) and unicornuate (10.0%). 70.6% of women with congenital uterine anomalies had a full-term live birth, 26.8% had a preterm live birth, 2.1% had an abortion or stillbirth, and 0.4% had an ectopic pregnancy. 61.8% of preterm births occurred between 33 and 36 weeks, 16.9% between 30 and 32 weeks, and 21.3% at <30 weeks. There were 1,440 (2.9%) periviable births. The preterm (34.5%) and periviable (6.9%) birth rates were highest in the uterine didelphys group. Overall, two-thirds (65.7%) of patients with congenital uterine anomalies were delivered via cesarean section. When compared to arcuate uterus, risk of severe maternal morbidity in septate uterus (4.8% vs 2.6%, adjusted-odds ratio [aOR] 2.60, 95% confidence interval [CI] 1.49-4.52) was increased, including hemorrhage (14.5% vs 7.7%, aOR 2.16, 95% CI 1.51-3.07). This was followed by uterine didelphys (4.2% vs 2.6%, aOR 1.75, 95% CI 1.24-2.47), unicornuate uterus (3.8% vs 2.6%, aOR 1.61, 95% CI 1.29-2.01), and bicornuate uterus (3.0% vs 2.6%, aOR 1.23, 95% CI 1.04-1.47). CONCLUSION While the majority of patients with congenital uterine anomalies result in full-term viable deliveries, each subtype of congenital uterine anomalies confers different obstetric risks. Uterine didelphys was associated with the highest risk of preterm birth, while septate uterus was associated with the highest risk of severe maternal morbidity. While this hospital delivery dataset likely overrepresents bicornuate uteri, this populational data may help inform patients with congenital anomalies considering pregnancy.

Abstract
OBJECTIVES Patients with a septate uterus often have endometriosis, which can exacerbate their adverse pregnancy outcomes. We aimed to describe the clinical characteristics and treatment outcomes of patients with a septate uterus complicated by endometriosis. STUDY DESIGN This retrospective study included patients who had a septate uterus complicated by endometriosis and were treated in Wuhan Tongji Hospital in the past 10 years. The characteristics of patients with a septate uterus and endometriosis were collected and described in terms of their preoperative and postoperative pregnancy outcomes. RESULTS There were 24 cases with a complete septate uterus and 49 cases with an incomplete septate uterus.Combinations of other malformations are more common in patients with complete septate uterus. In patients with a septate uterus, endometriosis often affected the ovaries, most commonly the left side (P < 0.001). Non-significant difference in the staging of endometriosis between complete and incomplete septate uterus (P= 0.812). Surgical treatment greatly improved the reproductive function and increased the live birth rate of patients with a septate uterus complicated by endometriosis (P < 0.001). CONCLUSIONS Compared to a septate uterus uncomplicated endometriosis, a septate uterus complicated by endometriosis significantly affects reproductive function. Surgical treatment can significantly improve the pregnancy outcomes of patients with a septate uterus and endometriosis. Clinicians should pay attention to timely diagnosing and treating these patients.

Impact of Inherited Thrombophilia in Women with Obstetric Antiphospholipid Syndrome: A Single-Center Study and Literature Review. Biomedicines 2024; 12:1174. [PMID: 38927381 PMCID: PMC11201097 DOI: 10.3390/biomedicines12061174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 05/17/2024] [Accepted: 05/23/2024] [Indexed: 06/28/2024] Open
Abstract
Inherited thrombophilia (IT) has been implicated as a potential causal factor of adverse pregnancy outcomes (APOs), including recurrent miscarriage with and without the presence of antiphospholipid syndrome (APS). The aim of this study was to assess the prevalence and impact of IT on fetal-maternal outcomes and thrombotic risk in women within the spectrum of obstetric APS. Three hundred and twenty-eight women with APS-related obstetric morbidity ever pregnant were included. Of these, 74 met the APS classification criteria, 169 were non-criteria (NC)-APS, and 85 were seronegative (SN)-APS. Patients with other autoimmune diseases were excluded. APOs included early pregnancy loss, fetal death, preeclampsia, abruptio placentae, and preterm birth. Successful pregnancy was defined as the achievement of a live newborn. A literature search was also performed. The mean age of the overall group was 33.9 ± 5.3 years, and the patients were followed up for 35 (11-79) months. During the study period, there were 1332 pregnancies. Nearly 14% of the patients had an associated IT. IT patients more frequently received the standard-of-care (SoC) therapy. The presence of IT was not associated with worse maternal-fetal outcomes in patients treated with SoC treatment. Overall, IT patients had a lower frequency of newborns without treatment, especially those without definite APS. In addition, IT did not increase the risk of thrombosis during pregnancy or the postpartum period. A detailed analysis of the literature review identified only four publications related to our study and did not show conclusive evidence of the impact of IT on patients with obstetric APS. The group of women with APS-related obstetric morbidity and IT who did not receive treatment, especially those without definite APS, had a worse prognosis in terms of a live birth. However, with SoC therapy, the prognosis is similar in those patients without IT. The association of IT with APS does not seem to predispose to the development of thrombosis during pregnancy and/or the postpartum period.

Abstract
OBJECTIVES To investigate the effect of subacute exposure of Di (2-ethylhexyl) phthalate (DEHP) on endometrial decidualization in mice. METHODS CD1 mice were orally administrated with 300 mg·kg-1·d-1 (low-dose group), 1000 mg·kg-1·d-1 (medium-dose group), or 3000 mg·kg-1·d-1 DEHP (1/10 LD50, high-dose group) for 28 days, respectively. The early natural pregnancy model and artificially induced decidualization model were established, and the uterine tissues were collected on D7 of natural pregnancy and D8 of artificially induced decidualization, respectively. The effects of subacute exposure to DEHP on the decidualization of mice were detected by HE staining, Masson staining, TUNEL staining, and Western blotting, respectively. A model of spontaneous abortion was constructed in mice after subacute exposure to 300 mg·kg-1·d-1 DEHP, and the effect of impaired decidualization on pregnancy was investigated by observing the pregnancy outcome on the 10th day of gestation. RESULTS Compared with the control group, the conception rate was significantly lower in the high-dose DEHP subacute exposure group. HE staining showed that, compared with the control group, the decidual stromal cells in the low- and medium-dose exposure groups were disorganized, the nuclei of the cells were irregular, the cytoplasmic staining was uneven, and the number of polymorphonuclear cells was significantly reduced. Masson staining showed that compared with the control group, the collagen fibers in the decidua region of the DEHP low-dose group and the medium-dose group were more distributed, more abundant and more disorderly. TUNEL staining showed increased apoptosis in the decidua area compared to the control group. Western blotting showed that the expression of BMP2, a marker molecule for endometrial decidualization, was significantly reduced. The abortion rate and embryo resorption rate were significantly higher, and the number of embryos, uterine wet weight, uterine area and placenta wet weight were significantly lower in mice exposed to 300 mg·kg-1·d-1 DEHP than in control mice stimulated by mifepristone abortifacient drug. CONCLUSIONS Subacute exposure to DEHP leads to impaired endometrial decidualization during early pregnancy and exacerbates the risk of adverse pregnant outcomes in mice.

Abstract
OBJECTIVE To describe the incidence of uterovaginal anomalies and histologic findings in transgender and nonbinary (TGNB) patients seeking hysterectomies. METHODS All patients receiving gender-affirming hysterectomies between 2013 and 2023 were retrospectively reviewed. Primary outcomes included uterovaginal anomalies and histological findings. Multivariable logistic regressions were performed to evaluate relationships between variables of interest and whether they predict findings of uterovaginal anomalies, inactive endometrium, adenomyosis, leiomyoma, endometriosis, and cervical atrophy. RESULTS 278 patients received hysterectomies at an average age of 29.2 ± 8.3 years. Seven patients (2.5%) were found to have a developmental anomaly, including two bicornuate uterus (0.7%), two unicornuate uterus (0.7%), one septate uterus (0.4%), and two vaginal septum (0.7%). 60 patients (21.6%) were found to have inactive endometrium and 26 patients (9.4%) had cervical atrophy. Although 262 patients (94.2%) were on testosterone therapy, hormone duration was not a significant predictor of any uterine findings. CONCLUSION This study describes uterovaginal anomalies in a large cohort of patients receiving gender-affirming hysterectomies. Although long-term testosterone use is commonly believed to be associated with endometrial and cervical atrophy, this study shows no such association.

Abstract
Spontaneous abortion is the most common complication in early pregnancy, the exact etiology of most cases cannot be determined. Emerging studies suggest that mutations in ciliary genes may be associated with progression of pregnancy loss. However, the involvement of primary cilia on spontaneous abortion and the underlying molecular mechanisms remains poorly understood. We observed the number and length of primary cilia were significantly decreased in decidua of spontaneous abortion in human and lipopolysaccharide (LPS)-induced abortion mice model, accompanied with increased expression of proinflammatory cytokines interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α. The length of primary cilia in human endometrial stromal cell (hESC) was significantly shortened after TNF-α treatment. Knocking down intraflagellar transport 88 (IFT88), involved in cilia formation and maintenance, promoted the expression of TNF-α. There was a reverse regulatory relationship between cilia shortening and TNF-α expression. Further research found that shortened cilia impair decidualization in hESC through transforming growth factor (TGF)-β/SMAD2/3 signaling. Primary cilia were impaired in decidua tissue of spontaneous abortion, which might be mainly caused by inflammatory injury. Primary cilia abnormalities resulted in dysregulation of TGF-β/SMAD2/3 signaling transduction and decidualization impairment, which led to spontaneous abortion.

[PMID: 38360394 DOI: 10.1016/j.jmig.2024.02.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 01/28/2024] [Accepted: 02/07/2024] [Indexed: 02/17/2024]
Abstract
STUDY OBJECTIVE To study pregnancy outcomes after single euploid embryo transfer (SEET) in patients who underwent prior uterine septum resection to those with uteri of normal contour, without Müllerian anomalies or uterine abnormalities including polyps or fibroids, and without a history of prior uterine surgeries. DESIGN Retrospective cohort study. SETTING Single academic affiliated center. PATIENTS 60 cycles of patients with prior hysteroscopic uterine septum resection who underwent an autologous SEET between 2012 and 2020 were used as the investigational cohort. A 3:1 ratio propensity score matched control cohort of 180 single euploid embryo transfer cycles from patients without a history of uterine septa were used as the control group. INTERVENTIONS No interventions administered. MEASUREMENTS AND MAIN RESULTS Pregnancy, clinical pregnancy loss, ongoing clinical pregnancy, and live birth rates in patients with a history of uterine septum resection compared with matched patients without Müllerian anomalies or uterine surgeries. Patients with a prior uterine septum had significantly lower rates of chemical pregnancy (58.33% vs 77.2%, p = .004), implantation (41.67% vs 65.6%, p = .001), and live birth (33.33% vs 57.8%, p = .001) per transfer. No statistical difference in clinical pregnancy loss rates was found when comparing septum patients with controls (8.33% vs 7.8%, p = .89). CONCLUSION Patients with a history of hysteroscopic resection who undergo in vitro fertilization are more susceptible to suboptimal clinical outcomes compared with patients with normal uteri. Early pregnancy loss rates in patients with a uterine septum are higher than in those without; however, after resection, the rates are comparable. Patients born with septate uteri require assessment of surgical intervention prior to SEET, and to optimize their reproductive outcomes.

Abe J, Nasu T, Noro A, Tsubaki J. An unusual case of severe asphyxia with the fetal position unexpectedly inverted in a malformed uterus: a case report. J Med Case Rep 2024; 18:209.

Abstract
BACKGROUND We present a severe neonatal consequence due to the unexpected and crucial inversion of the fetal position after sudden termination of tocolysis during early labor of a woman with congenital uterine anomaly. It has been reported that congenital uterine anomalies latently affect the fetal position. The clinical pitfalls in childbirth with uterine anomalies are discussed here on the basis of clinical evidence. CASE PRESENTATION At a perinatal medical center in Japan, a 29-year-old Japanese mother who had a history of bicornuate uterus, received tocolysis to prolong her pregnancy for 5 days during the late preterm period after preterm-premature rupture of the membrane. She gave birth to a 2304 g male neonate of the gestational age of 35 weeks and 5 days with severe asphyxia by means of crash cesarean section for fetal sustained bradycardia after sudden termination of tocolysis. We found the fetal position to reverse from cephalic to breech position during early labor. He ended up having severe cerebral palsy after brain cooling against hypoxic-ischemic encephalopathy for 3 days. The mechanism of inversion from cephalic to breech position without amnionic fluid remains unclear, although women with a known diagnosis of a uterine anomaly have higher risk of adverse outcomes such as malpresentation. CONCLUSIONS When considering the clinical course of this case on the basis of the medical reports, we suspected that uterine anomalies and changes in intrauterine pressure could cause fetal malpresentation and adverse neonatal outcomes.

Abstract
INTRODUCTION The management of a pregnancy in a bicornuate uterus is particularly challenging. A bicornuate uterus is a rare occurrence and a twin pregnancy in a bicornuate uterus even more rare. These pregnancies call for intensive diagnostic investigation and interdisciplinary care. CASE PRESENTATION We report on a 27-year-old European woman patient (gravida I, para 0) with a simultaneous pregnancy in each cavity of a bicornuate bicollis uterus after embryo transfer. The condition was confirmed by hysteroscopy and laparoscopy. Several unsuccessful in vitro fertilization (IVF) attempts had been performed earlier before embryo transfer in each cornus. After a physiological course of pregnancy with differential screening at 12 + 6 weeks and 22 + 0 weeks of gestation, the patient presented with therapy-resistant contractions at 27 + 2 weeks. This culminated in the uncomplicated spontaneous delivery of the leading fetus and delayed spontaneous delivery of the second fetus. DISCUSSION Only 16 cases of twin pregnancy in a bicornuate unicollis uterus have been reported worldwide and only 6 in a bicornuate bicollis uterus. The principal risks in such pregnancies are preterm labor, intrauterine growth restriction, malpresentation and preeclampsia. These typical risk factors of a twin pregnancy are greatly potentiated in the above mentioned setting. CONCLUSION A twin pregnancy in the presence of a uterine malformation is rare and difficult to manage. These rare cases must be collected and reported in order to work out algorithms of monitoring and therapy as well as issue appropriate recommendations for their management.

Abstract
STUDY OBJECTIVE Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) includes uterine didelphys, unilateral obstructed hemivagina, and ipsilateral renal anomaly. Surgical management of this condition relies on accurate diagnosis to excise the obstructed longitudinal vaginal septum (OLVS). Vital considerations involve identifying the side affected, ipsilateral renal anomaly (IRA), thickness of the septum (TS), septal axis (SA), and distance of the septum to perineum (DSP). The study aimed to evaluate the preoperative characteristics, imaging findings, and surgical outcomes of OHVIRA. METHODS Institutional review board approval was obtained for this retrospective chart review. ICD-10 codes identified OHVIRA cases between 2012 and 2019 at a single children's hospital. Patient demographic characteristics, magnetic resonance imaging findings, surgical management, outcomes, and complications were reviewed. Descriptive statistics were utilized. RESULTS Twenty-six patients met inclusion criteria. Most were diagnosed at puberty (92%). Abdominal pain (50%) was the most common presenting complaint. The mean age of diagnosis was 13.2 years overall and 11.2 years for those with regular cycles vs 13.4 years for those with irregular cycles. Preoperative imaging showed predominant right-sided OLVS (50%), IRA (77%), and oblique SA (65%). All patients underwent vaginoscopy, septum resection, and vaginoplasty, except 1 who was managed with an abdominal drain as a neonate. Four required postoperative vaginal stent or Foley, with DSP greater than 5 cm in all cases. One intraabdominal abscess complication occurred. No instances of hematocolpos re-accumulation or reoperation were observed during the 3-year follow-up period. CONCLUSION This study demonstrates that detailed preoperative planning and a systematic surgical approach lead to favorable outcomes in OHVIRA irrespective of the OLVS laterality, TS, SA, or DSP.

JPT2 Affects Trophoblast Functions and Macrophage Polarization and Metabolism, and Acts as a Potential Therapeutic Target for Recurrent Spontaneous Abortion. ADVANCED SCIENCE (WEINHEIM, BADEN-WURTTEMBERG, GERMANY) 2024; 11:e2306359.

Abstract
Recurrent spontaneous abortion (RSA) is a pregnancy-related condition with complex etiology. Trophoblast dysfunction and abnormal macrophage polarization and metabolism are associated with RSA; however, the underlying mechanisms remain unknown. Jupiter microtubule-associated homolog 2 (JPT2) is essential for calcium mobilization; however, its role in RSA remains unclear. In this study, it is found that the expression levels of JPT2, a nicotinic acid adenine dinucleotide phosphate-binding protein, are decreased in the villous tissues of patients with RSA and placental tissues of miscarried mice. Mechanistically, it is unexpectedly found that abnormal JPT2 expression regulates trophoblast function and thus involvement in RSA via c-Jun N-terminal kinase (JNK) signaling, but not via calcium mobilization. Specifically, on the one hand, JPT2 deficiency inhibits trophoblast adhesion, migration, and invasion by inhibiting the JNK/atypical chemokine receptor 3 axis. On the other hand, trophoblast JPT2 deficiency contributes to M1 macrophage polarization by promoting the accumulation of citrate and reactive oxygen species via inhibition of the JNK/interleukin-6 axis. Self-complementary adeno-associated virus 9-JPT2 treatment alleviates embryonic resorption in abortion-prone mice. In summary, this study reveals that JPT2 mediates the remodeling of the immune microenvironment at the maternal-fetal interface, suggesting its potential as a therapeutic target for RSA.

Abstract
OBJECTIVE To provide evidence-based recommendations regarding the diagnosis and effectiveness of surgical treatment of a uterine septum. METHODS This guideline provides evidence-based recommendations regarding the diagnosis and effectiveness of surgical treatment of a uterine septum. This replaces the last version of the same name (Fertil Steril. 2016 Sep 1;106(3):530-40). MAIN OUTCOME MEASURE(S) Outcomes of interest included the impact of a septum on underlying fertility, live birth, clinical pregnancy, and obstetrical outcomes. RESULT(S) The literature search identified relevant studies to inform the evidence for this guideline. CONCLUSION(S) The treatment of uterine septa and subsequent outcomes associated with infertility, recurrent pregnancy loss, and adverse obstetrical outcomes are summarized. Resection of a septum has been shown to improve outcomes in patients with recurrent pregnancy loss and to decrease the likelihood of malpresentation. In the setting of infertility, it is recommended to use a shared decision-making model after appropriate counseling to determine whether or not to proceed with septum resection.

Abstract
OBJECTIVE This retrospective study aimed to assess the impact of hysteroscopic septum incision on in vitro fertilization (IVF) outcomes among infertile women diagnosed with a complete septate uterus and no history of recurrent pregnancy loss. METHODS The study was conducted at a tertiary reproductive center affiliated with a university hospital and involved 78 women with a complete septate uterus. Among them, 34 women underwent hysteroscopic septum incision, while 44 women opted for expectant management. The primary outcome measure was the live birth rate, while secondary outcomes included clinical pregnancy rate, preterm birth rate, miscarriage rate, and ongoing pregnancy rate. RESULTS Women who underwent hysteroscopic septum incision demonstrated a comparable likelihood of achieving a live birth compared to those managed expectantly (25% vs. 25%, Relative Risk (RR): 1.000, 95% Confidence Interval (CI): 0.822 to 1.216). No preterm births occurred in either group. The clinical pregnancy rate, ongoing pregnancy rate, and miscarriage rate showed no significant differences between the surgical group and the expectant management group. Subgroup analyses based on the type of embryo transferred also revealed no significant differences in outcomes. CONCLUSIONS Hysteroscopic septum incision does not appear to yield improved IVF outcomes compared to expectant management in infertile women with a complete septate uterus and no history of recurrent pregnancy loss.

Abstract
Background Primary rupture of an unscarred uterus is rare. Spontaneous rupture of an unscarred bicornuate uterus is a life-threatening obstetric emergency with high morbidity and mortality in the mother and fetus; however, it most commonly occurs in the first trimester of pregnancy. Case A 20-year-old primigravid woman at 22 weeks of gestation, with no prior surgery, presented with severe abdominal pain, anemia, and hemodynamic instability. With a preoperative diagnosis of uterine rupture, she was transfused with three units of cross-matched whole blood and underwent emergency laparotomy. Intraoperative findings showed a ruptured bicornuate uterus and a dead fetus in the abdomen with huge hemoperitoneum. Postoperative recovery was smooth, and the patient was discharged after being counselled on family planning and subsequent pregnancy. Conclusion A bicornuate uterus may be an independent risk factor for uterine rupture, which can occur in primigravid women at any stage of pregnancy. Each obstetrician should have a high index of suspicion for a rare condition like ruptured bicornuate uterus, especially for a pregnant woman presenting with acute abdominal pain and hemodynamic instability. Early ultrasonography plays a key role in the evaluation, follow-up, and management of these patients.

Abstract
Mitogen-activated protein 3 kinase 1 (MAP3K1) has a plethora of cell type-specific functions not yet fully understood. Herein, we describe a role for MAP3K1 in female reproductive tract (FRT) development. MAP3K1 kinase domain-deficient female mice exhibited an imperforate vagina, labor failure and infertility. These defects corresponded with shunted Müllerian ducts (MDs), the embryonic precursors of FRT, that manifested as a contorted caudal vagina and abrogated vaginal-urogenital sinus fusion in neonates. The MAP3K1 kinase domain is required for optimal activation of the Jun-N-terminal kinase (JNK) and cell polarity in the MD epithelium, and for upregulation of WNT signaling in the mesenchyme surrounding the caudal MD. The MAP3K1-deficient epithelial cells and MD epithelium had reduced expression of WNT7B ligands. Correspondingly, conditioned media derived from MAP3K1-competent, but not -deficient, epithelial cells activated a TCF/Lef-luciferase reporter in fibroblasts. These observations indicate that MAP3K1 regulates MD caudal elongation and FRT development, in part through the induction of paracrine factors in the epithelium that trans-activate WNT signaling in the mesenchyme.

Abstract
Müllerian anomalies represent a complex collection of developmental defects occurring in up to 5% of the general population. They are increasingly more common in individuals with infertility (8.0%) and in those with a history of pregnancy loss (13.3%); they have the highest prevalence in individuals with a history of both (24.5%). A wide spectrum of anomalies can occur based on the stage at which müllerian development ceases in utero, ranging from mild (eg, a partial uterine septum) to severe, with complete absence of the cervix, uterus, and fallopian tubes (eg, müllerian agenesis). The components of the reproductive tract involved and, importantly, whether an obstruction of the tract is involved correlates with the timing of presentation, the constellation of associated symptoms, and the necessity for either medical or surgical management. Individuals, regardless of the severity of the defect, should be counseled on the gynecologic, reproductive, and obstetric risks associated with their specific müllerian anomaly to minimize adverse sequela and outcomes. We will review the clinical presentation, diagnostic evaluation, and clinical counseling of individuals with müllerian anomalies.

Abstract
Background Congenital uterine anomalies (CUA) can be associated with impairments of early and late pregnancy events. Objective To assess the impact of CUA on reproductive outcomes in pregnancies conceived spontaneously or after assisted reproduction. Materials and Methods Systematic review and meta-analysis of cohort studies comparing patients with CUA versus women with normal uterus. A structured literature search was performed in leading scientific databases to identify prospective and retrospective studies. The Newcastle-Ottawa scale, adapted to AHRQ standards, was used to assess the risk of bias. Pooled odds ratios (OR) were calculated. Publication bias and statistical heterogeneity were assessed, and meta-regression was used to analyse the heterogeneity. Main outcome measures Miscarriage, ectopic pregnancy, placental abruption, term, and premature rupture of membranes (PROM), malpresentation at delivery, preterm delivery prior to 37, 34 and 32 weeks, caesarean delivery, intrauterine growth restriction/small for gestational age, foetal mortality and perinatal mortality. Results 32 studies were included. CUAs increased significantly the risk of first/second trimester miscarriage (OR:1.54;95%CI:1.14-2.07), placental abruption (OR:5.04;3.60-7.04), PROM (OR:1.71;1.34-2.18), foetal malpresentation at delivery (OR:21.04;10.95-40.44), preterm birth (adjusted OR:4.34;3.59-5.21), a caesarean delivery (adjusted OR:7.69;4.17-14.29), intrauterine growth restriction/small for gestational age (adjusted OR:50;6.11-424), foetal mortality (OR:2.07;1.56-2.73) and perinatal mortality (OR:3.28;2.01-5.36). Conclusions CUA increases the risk of complications during pregnancy, delivery, and postpartum. Complications most frequent in CUA patients were preterm delivery, foetal malpresentation, and caesarean delivery. What is new? Bicornuate uterus was associated with the highest number of adverse outcomes, followed by didelphys, subseptate and septate uterus.

Abstract
Most preterm births occur in the late preterm period. While prematurity-related adverse outcomes are significantly diminished when birth occurs during this period, these infants are still at increased risk of complications. Parity affects the incidence of obstetric complications. The purpose of this study was to determine whether parity impacts the risk of spontaneous late preterm birth (SLPTB) and associated complications. A retrospective observational cohort study was conducted. Patients were divided into three study groups according to parity. The primary outcome was the rate of SLPTB in each group. Secondary outcomes were unplanned cesarean delivery (UCD), prolonged third stage of labor respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN), intraventricular hemorrhage (IVH), neonatal hypoglycemia, duration of NICU admission, neonatal death, and composite adverse neonatal outcome (CANO). Primiparas were more likely to have SLPTB, UCD, and CANO compared to multiparas (2.6% vs. 1.9% OR 1.5 [1.3-1.7] p < 0.01) (4.1% vs. 1.3% OR 2.7 [1.2, 5.9] p < 0.01) (8.5% vs. 4.2 OR 2.1 [1.3-3.5] p = 0.002) and grandmultiparas (2.6% vs. 1.7% OR 1.4 [1.2-1.5] p < 0.001) 8.5% vs. 4.4% OR 2.0 [1.1, 3.8], p = 0.01) but no difference in UCD compared to grandmultiparas (4.1% vs. 3.3% OR 1.2 [0.6-2.7] p = 0.28). Primiparas are at increased risk of SLPTB and UCD, and this is accompanied by an increased risk of adverse neonatal outcomes.

Abstract
OBJECTIVE To study the impact of congenital uterine anomalies on reproductive outcomes after in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI)-embryo transfer (ET). METHODS A retrospective study including a total of 865women with congenital uterine anomalies and 865 age and admission time matched controls who underwent the first IVF/ICSI-ET cycle between January 2010 and December 2019 was conducted. Women with uterine anomalies were classified into canalization defect (complete septate uterus and subseptate uterus) and unification defect (unicornuate uterus, bicornuate uterus, and didelphus uterus) according to the processes of abnormal embryological development. Control women were selected by age (± 1.0 year) and admission time (± 6 months) matched with a 1:1 ratio. The reproductive outcomes were compared between women with uterine anomalies and the controls. The primary outcome was live birth; secondary outcomes were clinical pregnancy, ectopic pregnancy, preterm delivery, and spontaneous pregnancy loss. RESULTS Compared with women with a normal uterus, women with canalization defects were less likely to experience live birth [84/332 (25.3%) vs 128/332 (38.6%), RR: 0.647, 95% CI 0.513-0.815, P < 0.001]. They also had a lower clinical pregnancy rate [126/332 (38.0%) vs 206/332 (62.0%), RR: 0.829, 95% CI 0.690-0.997, P = 0.046] and experienced a higher first-trimester pregnancy loss rate [25/126 (19.8%) vs 11/206 (5.3%), RR: 2.716, 95% CI 1.393-5.295, P = 0.003]. Compared with women with a normal uterus, women with a unification defect were also less likely to experience live birth [132/533 (24.8%) vs 219/533 (41.1%), RR: 0.713, 95% CI 0.586-0.868, P = 0.001]. Women with a unification defect had lower clinical pregnancy rates [182/533 (34.1%) vs 263/533 (49.1%), RR: 0.813, 95% CI 0.695-0.952, P = 0.010] and increased first-trimester pregnancy loss [36/182 (19.8%) vs 20/263 (7.6%), RR: 3.288, 95% CI 1.776-6.085, P < 0.001]. While uterine anomaly seemed not increase the risk of preterm birth, ectopic pregnancy and second-trimester pregnancy loss. CONCLUSIONS Both canalization defects and unification defects were associated with lower fertility outcomes, including lower live birth rates, lower clinical pregnancy rates, and higher early miscarriage rates.

Abstract
PURPOSE Septate uterus is the most common congenital uterine malformation. This retrospective cohort study compared clinical outcomes and second-look hysteroscopy findings in patients with complete and incomplete septate uteri after septoplasty. METHODS We reviewed the medical records of patients with a septate uterus who underwent hysteroscopic septoplasty and second-look hysteroscopy at the West China Second University Hospital between September 2013 and September 2021. Information regarding pregnancy outcomes was collected through telephone interviews. The independent samples t-test, Mann-Whitney U test, Pearson's chi-square test, and Fisher's exact test were used to explore the differences between the complete and incomplete septate uterus groups. RESULTS A total of 64 patients were enrolled in this study. There was no significant difference in intrauterine adhesion (IUA) rates (16.7% and 32.1%), pregnancy rates (44.1% and 42.9%), term delivery rates (35.3% and 32.1%), premature delivery rates (2.9% and 0), placenta previa rates (2.9% and 3.6%), placenta implantation/adhesion rates (5.9% and 3.6%), and premature rupture of membranes rates (2.9% and 0) between the complete and the incomplete group after hysteroscopic septoplasty (P > 0.05). Endometrial polyps in the septate uterus were common, with an incidence of 33.3% and 25% in the complete and incomplete groups, respectively (P > 0.05). CONCLUSION The pregnancy outcomes of complete and incomplete septate uteri after hysteroscopic septoplasty were similar. There was no statistical difference in IUAs after surgery. Different treatment strategies may not be required for complete or incomplete septate uteri.

Abstract
OBJECTIVE The aim of the study is to estimate the association between arcuate uterus and pregnancy outcomes using controls selected from a similarly high-risk cohort. STUDY DESIGN This is a retrospective cohort study of women with an arcuate uterus cared for by a single maternal-fetal medicine practice from 2005 to 2020. We included all women with a singleton pregnancy ≥20 weeks and diagnosis of arcuate uterus and randomly selected (3:1) patients with a singleton pregnancy and no uterine anomaly from the same practice as controls. Baseline characteristics and pregnancy outcomes were compared between the two groups. Chi-square, Fisher's exact, and independent samples t-test were used for data analysis, as indicated. RESULTS A total of 37 women with an arcuate uterus (55 independent singleton pregnancies) and 165 controls were included. There were no differences in baseline characteristics. Women with an arcuate uterus had a significantly higher rate of spontaneous preterm birth less than 37 weeks (10.9 vs. 3.0%, p = 0.031) and were more likely to require vaginal progesterone (5.5 vs. 0.6%, p = 0.049) and administration of antenatal corticosteroids (16.4 vs. 5.5%, p = 0.020). Arcuate uterus was also associated with lower birthweight (3,028.1 ± 528.0 vs. 3257.2 ± 579.9 g, p = 0.010) and higher incidence of intrauterine fetal growth restriction (20.0 vs. 7.3%, p = 0.008), despite similar starting body mass index (BMI) and weight gain throughout pregnancy. There were no differences in preeclampsia, malpresentation, cesarean delivery, blood transfusion, retained placenta, or morbidly adherent placenta. CONCLUSION Arcuate uterus is associated with a significantly increased risk of spontaneous preterm birth (<37 weeks), need for vaginal progesterone for short cervix and antenatal corticosteroids, fetal growth restriction, and lower mean birthweight. These findings suggest that arcuate uterus is not just a normal variant of uterine anatomy but rather a risk factor for poor fetal growth, short cervix, and a higher risk pregnancy. KEY POINTS · Arcuate uterus is associated with increased risk of preterm birth and fetal growth restriction.. · Women with arcuate uteri had higher rates of vaginal progesterone use during pregnancy.. · Arcuate uterus should be treated as a true finding rather than a normal anatomical variant..

Abstract
Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) is a rare congenital developmental syndrome manifested by uterine duplication, lower genital tract obstruction, and unilateral renal anomaly. Literature on reproductive outcomes in this patient population is limited. The aim of this study is to describe obstetric outcomes after surgical correction of obstructed hemivagina in a longitudinal cohort of patients with a diagnosis of OHVIRA. All cases of OHVIRA presenting to a single tertiary care children's hospital from 1990 to 2021 were retrospectively reviewed. Three cases demonstrating a variety of clinically important reproductive outcomes are described in detail including risks such as retained products, endometritis, preterm labor, and malpresentation. Understanding the reproductive outcomes associated with this diagnosis is important for practitioners seeking to counsel and care for patients with this diagnosis. This case series demonstrates a wide array of potential gynecologic and obstetric risks, though ultimately with successful term and near-term pregnancies.

Abstract
Preterm birth (PTB) affects approximately 10% of births globally each year and is the most significant direct cause of neonatal death and of long-term disability worldwide. Early identification of women at high risk of PTB is important, given the availability of evidence-based, effective screening modalities, which facilitate decision-making on preventative strategies, particularly transvaginal sonographic cervical length (CL) measurement. There is growing evidence that combining CL with quantitative fetal fibronectin (qfFN) and maternal risk factors in the extensively peer-reviewed and validated QUanititative Innovation in Predicting Preterm birth (QUiPP) application can aid both the triage of patients who present as emergencies with symptoms of preterm labor and high-risk asymptomatic women attending PTB surveillance clinics. The QUiPP app risk of delivery thus supports shared decision-making with patients on the need for increased outpatient surveillance, in-patient treatment for preterm labor or simply reassurance for those unlikely to deliver preterm. Effective triage of patients at preterm gestations is an obstetric clinical priority as correctly timed administration of antenatal corticosteroids will maximise their neonatal benefits. This review explores the predictive capacity of existing predictive tests for PTB in both singleton and multiple pregnancies, including the QUiPP app v.2. and discusses promising new research areas, which aim to predict PTB through cervical stiffness and elastography measurements, metabolomics, extracellular vesicles and artificial intelligence.

Omoto A, Ishikawa H, Inoue M, Morimoto S, Koga K, Shozu M. Metroplasty increases the take-home baby rate by reducing pregnancy loss without changing the chance of conception in women with septate uterus: a retrospective, single-center, observational study. BMC Pregnancy Childbirth 2023; 23:860. [PMID: 38098016 PMCID: PMC10720111 DOI: 10.1186/s12884-023-06191-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 12/11/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Although abdominal or hysteroscopic metroplasty for septate uterus is considered to reduce pregnancy loss and increase the take-home baby (THB) rate in women with a history of recurrent pregnancy loss, there exists an inherent risk of impaired fertility. This study aimed to clarify the reproductive outcomes of women with septate uterus who underwent abdominal and hysteroscopic metroplasty in a single center. METHODS This retrospective observational study enrolled 27 women who underwent metroplasty between 2007 and 2019. The analysis included women with septate uterus [European Society of Human Reproduction and Embryology (ESHRE)/European Society for Gynaecological Endoscopy (ESGE) type U2)] or septate-bicornuate uterus (ESHRE/ESGE type U3b) who underwent either abdominal or hysteroscopic metroplasty. Women who did not have an immediate desire to conceive were excluded from the analysis. As a rule, we recommended pregnancy without surgery for women who had not experienced repeated pregnancy loss. Abdominal metroplasty (ABM) was performed using the modified Tompkins' method and hysteroscopic metroplasty was performed using hysteroscopic transcervical resection of the septum [transcervical metroplasty (TCM)]. The conception ratio was calculated as the number of women who achieved ≥ 1 conception/total number of women, the pregnancy loss ratio was calculated as the number of women who experienced ≥ 1 pregnancy loss/the number of women who conceived, and the THB ratio was calculated as the number of women who achieved ≥ 1 THB/total number of women. RESULTS Seventeen women underwent ABM and 10 women underwent TCM. Thirty-three conceptions and 26 babies were taken home after surgery. ABM did not change the ≥ 1 conception ratio (76% vs. 83% before and after surgery, respectively; RR = 1.08, p = 0.80). Meanwhile, ABM decreased the ≥ 1 pregnancy loss ratio (100% vs. 36%, RR = 0.36, p < 0.001) and increased the ≥ 1 THB ratio (12% vs. 71%, RR = 6.00, p < 0.01). Similarly, TCM did not change the ≥ 1 conception ratio, decreased the ≥ 1 pregnancy loss ratio, and increased the ≥ 1 THB ratio. CONCLUSIONS Both abdominal and hysteroscopic metroplasty for septate uterus increased the THB rate by preventing pregnancy loss without affecting the chance of pregnancy.

Abstract
BACKGROUND Preterm birth defined as delivery before 37 gestational weeks is a leading cause of neonatal and infant morbidity and mortality. The aim of this study is to summarize the evidence from meta-analyses of observational studies on risk factors associated with PTB, evaluate whether there are indications of biases in this literature, and identify which of the previously reported associations are supported by robust evidence. METHODS We searched PubMed and Scopus until February 2021, in order to identify meta-analyses examining associations between risk factors and PTB. For each meta-analysis, we estimated the summary effect size, the 95% confidence interval, the 95% prediction interval, the between-study heterogeneity, evidence of small-study effects, and evidence of excess-significance bias. Evidence was graded as robust, highly suggestive, suggestive, and weak. RESULTS Eighty-five eligible meta-analyses were identified, which included 1480 primary studies providing data on 166 associations, covering a wide range of comorbid diseases, obstetric and medical history, drugs, exposure to environmental agents, infections, and vaccines. Ninety-nine (59.3%) associations were significant at P < 0.05, while 41 (24.7%) were significant at P < 10-6. Ninety-one (54.8%) associations had large or very large heterogeneity. Evidence for small-study effects and excess significance bias was found in 37 (22.3%) and 12 (7.2%) associations, respectively. We evaluated all associations according to prespecified criteria. Seven risk factors provided robust evidence: amphetamine exposure, isolated single umbilical artery, maternal personality disorder, sleep-disordered breathing (SDB), prior induced termination of pregnancy with vacuum aspiration (I-TOP with VA), low gestational weight gain (GWG), and interpregnancy interval (IPI) following miscarriage < 6 months. CONCLUSIONS The results from the synthesis of observational studies suggest that seven risk factors for PTB are supported by robust evidence. Routine screening for sleep quality and mental health is currently lacking from prenatal visits and should be introduced. This assessment can promote the development and training of prediction models using robust risk factors that could improve risk stratification and guide cost-effective preventive strategies.

Abstract
BACKGROUND The association between uterine malformations and adverse pregnancy outcomes is well recognized. However, studies on adverse pregnancy outcomes based on one kind of anatomical commonality between different uterine anomalies have not been reported. This study aimed to investigate pregnancy outcomes in pregnancies with uterine malformations when the pregnancy is confined to a hemi-uterus. METHODS A retrospective observational study of 336 women who gave birth at our hospital from 2015 to 2021 was performed. Women (n = 112) with a unicornuate, complete bicornuate, or didelphic uterus were set as the study group, and women (n = 224) with a normal uterus were set as the reference group. Maternal and neonatal outcomes were evaluated and compared between the two groups using Student's t-test, one-way ANOVA, Chi-squared test, Yates correction for continuity, or Fisher's exact test. Modified Poisson regression analyses were used to estimate the relationships between the hemi-uterus pregnancy and preterm birth, preterm premature rupture of membranes, and cesarean section rates by adjusting for potential confounders. A P value < 0.05 was considered significant. RESULTS Women in the study group had a higher history of spontaneous abortion (24.1% vs. 10.7%, P = 0.002) and intrauterine fetal death (5.4% vs. 0.4, P = 0.006). Compared with the reference group, the study group had significantly higher rates of assisted reproductive technology (9.4% vs. 2.2%, P = 0.001) and cord-around-the neck (54.5% vs. 29.9%, P = 0.000). Modified Poisson regression analyses showed that the study group was at higher risk for preterm birth (aRR, 6.8; 95% CI 2.7-16.7), preterm premature rupture of membranes (aRR, 14.1; 95% CI 3.2-62.5), malpresentation (aRR, 13.2; 95% CI 6.3-27.7), and cesarean section (aRR, 4.4; 95% CI 3.3-5.7). CONCLUSION Women with a unicornuate, didelphic, or complete bicornuate uterus are at higher risk for some adverse pregnancy outcomes than those with a normal uterus.

Abstract
The physical and psychological impact of miscarriage can be devastating. There are many lifestyle and therapeutic interventions that may prevent a miscarriage. In this review, we have outlined the key areas for health optimization to prevent pregnancy loss, drawing on the most up-to-date evidence available. The 3 key areas identified are lifestyle optimization in women, lifestyle optimization in men, and therapeutic interventions. The evidence demonstrates that the treatments to consider are first-trimester progesterone administration, levothyroxine in women with subclinical hypothyroidism, and the combination of aspirin and heparin in women with antiphospholipid antibodies.

Abstract
OBJECTIVE To evaluate live-birth rates per embryo transfer in patients with uterine Müllerian anomalies (UMAs). Secondary objectives were to compare reproductive outcomes between the normal uterus group, the different UMA types, and UMA subgroups with and without required surgery. DESIGN This retrospective study compared two cohorts, one with UMAs and other with normal uteri of our oocyte donation program at 12 Instituto Valenciano De Infertilidad/Reproductive Medicine Associates University affiliated clinics from January 2000 to 2020. The oocyte donation reduces confounding because of differences in embryo quality. The primary outcome was the live-birth rate per embryo transfer. Secondary outcomes included the rates of implantation, clinical pregnancy, miscarriage, and ongoing pregnancy. We calculated odds ratios with 95% confidence intervals. PATIENTS Infertile women undergoing oocyte donation with UMAs. INTERVENTION None. MAIN OUTCOME MEASURES The rates of implantation, clinical pregnancy, miscarriage, ongoing pregnancy, and live birth. RESULTS We analyzed 58,337 cycles of oocyte donation: 57,869 patients had no uterine malformation, and 468 women had UMAs. Compared with patients with normal uteri, patients with UMAs had lower rates of live births (36.67% [32.84-40.65] vs. 38.1% [95% confidence intervals {CI}: 37.82-38.42]) and ongoing pregnancy (39.74% [35.93-43.66] vs. 41.5% [41.24-41.83]). The miscarriage rate was higher in patients with UMAs (19.5% [16.55-22.85] vs. 16.6% [16.47-16.92]). Specifically, patients with a unicornuate uterus (n=29) had lower rates of implantation (24.07% [13.49-37.64] vs. 42.85% [95% CI: 42.6-43.09]), pregnancy (41.86% [27.01-57.87] vs. 59.51% [59.22-59.81]), ongoing pregnancy (16.67% [6.97-31.36] vs. 41.54% [41.24-41.83]), and live births (16.67% [6.97-31.36] vs. 38.12% [37.83-38.42]). In addition, patients with a partial septate uterus (n=91) had a higher miscarriage rate (26.50% [18.44-34.89] vs. 16.7% [16.47-16.92]). Compared with the normal uterus group, the live-birth rates were lower in the UMA without surgery group (33.09% [27.59-38.96] vs. 38.12% [37.83-38.42]). CONCLUSION Among patients who received embryos derived from donated oocytes, live birth and ongoing pregnancy rates were lower in patients with UMAs compared with patients with normal uteri. A higher miscarriage rate was found in patients with UMAs. Patients with a unicornuate uterus had worse reproductive outcomes. Our results show that the uterus is less competent in patients with UMAs. TRIAL REGISTRATION This study was registered at clinicaltrial.gov (NCT04571671).

Abstract
STUDY OBJECTIVE This study aimed to develop and describe a novel surgical procedure that involves hysteroscopic fenestration with precise incision of the complete uterine septum and double cervix preservation after magnetic resonance imaging (MRI) evaluation in patients and to evaluate its efficacy. DESIGN A prospective consecutive clinical study. SETTING A university teaching hospital. PATIENTS Twenty-four patients with complete septate uterus and double cervix. INTERVENTIONS Three-dimensional reconstruction of uterus was performed with pelvic MRI and three-dimensional SPACE sequence scanning. Hysteroscopic fenestration with precise incision of the cavity septum and double cervix preservation was performed in patients. Three months after operation, follow-up pelvic MRI and second-look hysteroscopy were performed conventionally. MEASUREMENTS AND MAIN RESULTS Operating time, blood loss, operative complications, MRI and hysteroscopic changes of uterus, symptoms improvement, and reproductive outcomes were assessed. The surgery was successfully completed without any intraoperative complications in all patients. Operating time was 21.71 ± 8.28 minutes (range, 10-40 minutes) and blood loss was 9.92 ± 7.14 mL (range, 5-30 mL). Postoperative MRI showed the uterine anteroposterior diameter (3.66 cm vs 3.92 cm; p <.05) was increased. Postoperative MRI and the second-look hysteroscopy showed the cavity shape and uterine volume were expanded to the normal. Symptoms of dysmenorrhea, abnormal uterine bleeding, and dyspareunia were ameliorated after the surgery in 70% of patients (7 of 10), 60% of patients (3 of 5), and 1 patient, respectively. The preoperative spontaneous abortion rate was 80% (4 of 5) and the postoperative spontaneous abortion rate was 11.11% (1 of 9). After the surgery, there were 2 ongoing pregnancies and 6 pregnancies ended in term births. Two live births were delivered by cesarean section and 4 by vaginal delivery without cervical incompetence during pregnancy. CONCLUSIONS Hysteroscopic fenestration with precise incision of the uterine septum and double cervix preservation is an effective surgical procedure.

Abstract
This case report presents a unique clinical scenario involving a 32-year-old woman with a unicornuate uterus and a rudimentary horn, leading to recurrent fetal malpresentation. The patient, gravida 3, para 1, presented at 36 weeks of gestational age with contractions and vaginal bleeding. Clinical evaluation revealed a breech presentation and nonreassuring fetal heart tracings. An emergency cesarean section was performed, during which a unicornuate uterus with a rudimentary horn was identified and fused to the main uterine cavity on the left posterior aspect. The rudimentary horn bore a functional left tube and ovary. The surgical procedure was successful, resulting in the delivery of a healthy baby girl. This case underscores the importance of meticulous preoperative assessment, multidisciplinary collaboration, and informed consent in managing complex uterine anomalies to ensure optimal maternal and fetal outcomes.

J Minim Invasive Gynecol 2023; 30:725-734. [PMID: 37220845 DOI: 10.1016/j.jmig.2023.05.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 05/16/2023] [Accepted: 05/18/2023] [Indexed: 05/25/2023]
Abstract
STUDY OBJECTIVE To evaluate whether aggressive cervical dilation is effective for creating the initial perforation between noncommunicating cavities of the complete septate uterus (CSU), which serves as the first step of hysteroscopic cervix-preserving metroplasty (CPM). DESIGN A retrospective cohort. SETTING A tertiary referral center. PATIENTS Fifty-three patients with CSU were diagnosed using vaginal examinations, combined two- and three-dimensional vaginal ultrasounds, and office-based hysteroscopies. INTERVENTIONS Patients who had received hysteroscopic CPM with the initial perforation created by aggressive cervical dilation or by the traditional method of bougie-guided incisions were compared. MEASUREMENTS AND MAIN RESULTS Of the 53 patients with CSU, 44 patients received hysteroscopic CPM that required the creation of a perforation. Patients who received aggressive cervical dilation for creation of the perforation had nonsignificantly shorter surgical times (33.5 minutes, 95% confidence interval [CI], 28.4-38.6 vs 48.7 minutes, 95% CI, 28.2-71.3, p = .099), used significantly lower volumes of distending media (3.6 liters, 95% CI, 3.1-4.1 vs 6.8 liters, 95% CI, 4.2-9.3, p <.001), and had higher success rates (84.4%, 95% CI, 67.2-94.7 vs 50.0%, 95% CI, 21.1-78.9, p = .019). The sites of perforation all occurred on the endocervical septum and were generally fibrous and avascular. CONCLUSION We present a novel, effective method for creating the initial perforation in hysteroscopic CPM. The success may be because of the existence of a potential weakness in the septum of the duplicated cervix, which spontaneously tears upon aggressive mechanical dilation. The method forgoes the risks associated with sharp incisions based on potentially unreliable cues and may greatly simplify the procedure.

Abstract
PURPOSE OF REVIEW Congenital uterine anomalies (CUAs) impact the physical and psychosocial wellbeing of affected patients. Managing these conditions depends on the clinical scenario, and in some cases, can involve the use of minimally invasive surgical techniques. The purpose of this review is to provide an update of the diagnosis, perioperative considerations, and treatment of CUAs. RECENT FINDINGS The American Society for Reproductive Medicine (ASRM) updated the guidelines for classification of CUAs to provide practitioners with a standardized classification system and have created an interactive tool designed for provider use. SUMMARY Gynecologic surgeons are likely to encounter CUAs during their career. This review provides updated guidance for the workup and treatment of CUAs.

Abstract
Septate uterus is the most common congenital uterine malformation. It has been associated with poor reproductive outcomes, such as infertility and recurrent miscarriage, in the context of both assisted and non-assisted reproduction, though the exact underlying pathophysiological reasons remain unclear. Diagnosis is based on two-dimensional and three-dimensional ultrasound, magnetic resonance imaging, or laparoscopic/hysteroscopic findings. Hysteroscopic repair of the uterine septum has been shown to confer several benefits to reproductive outcomes, though this fact remains in question, due to inconsistent and or low-quality evidence in the medical literature. An individualized approach to the treatment of infertility patients with septate uteri is imperative, given the plethora of possible underlying factors that may complicate management. In this report, we present the case of a patient with a subseptate uterus and a history of infertility, who, following hysteroscopic metroplasty, managed to conceive and ultimately successfully deliver a healthy child.

Abstract
BACKGROUND Significant associations between the presence of polycystic ovary syndrome (PCOS) and uterine anomalies have been reported. It is unclear whether high anti-Müllerian hormone (AMH) levels coexist with the development of uterine malformations in women with PCOS. This study sought to investigate the association between Müllerian duct anomalies and anti-Müllerian hormone (AMH) levels in women with PCOS. METHODS In this retrospective cohort study, the records of 1,391 women with PCOS were analyzed. The cohort was divided into a low-AMH group (n = 700) and a high-AMH group (n = 691), based on an AMH cutoff value of 8.45 ng/ml. Müllerian duct anomalies were classified into four subtypes based on three-dimensional ultrasonography: septate uterus, bicornuate uterus, uterus didelphys, unicornuate uterus, and arcuate uterus. The primary outcome was the overall incidence of Müllerian duct anomalies. The secondary outcome was the prevalence of the abovementioned specific types of Müllerian duct anomalies. The prevalence of Müllerian duct anomalies was analyzed using the chi-squared test or Fisher's exact test. RESULTS Among the patients with PCOS, the prevalence of unicornuate uterus anomalies was higher in the high-AMH group than in the low-AMH group (1.0% vs. 0.1%, P = 0.04). No statistically significant difference in the overall incidence of uterine malformations was found between the two AMH groups (4.3% vs. 5.7%, P = 0.22). CONCLUSIONS Our study confirmed a higher prevalence of unicornuate uterus in PCOS women with high AMH levels. Clinicians might decide to investigate the possibility of a unicornuate uterus in PCOS women with high AMH levels.

Abstract
Mitogen-Activated Protein 3 Kinase 1 (MAP3K1) is a dynamic signaling molecule with a plethora of cell-type specific functions, most of which are yet to be understood. Here we describe a role for MAP3K1 in the development of female reproductive tract (FRT). MAP3K1 kinase domain-deficient ( Map3k1 ΔKD ) females exhibit imperforate vagina, labor failure, and infertility. These defects correspond to a shunted Müllerian duct (MD), the principle precursor of the FRT, in embryos, while they manifest as a contorted caudal vagina with abrogated vaginal-urogenital sinus fusion in neonates. In epithelial cells, MAP3K1 acts through JNK and ERK to activate WNT, yet in vivo MAP3K1 is crucial for WNT activity in mesenchyme associated with the caudal MD. Expression of Wnt7b is high in wild type, but low in Map3k1 knockout MD epithelium and MAP3K1-deficient keratinocytes. Correspondingly, conditioned media derived from MAP3K1-competent epithelial cells activate TCF/Lef-luciferase reporter in fibroblasts, suggesting that MAP3K1-induced factors released from epithelial cells trans-activate WNT signaling in fibroblasts. Our results reveal a temporal-spatial and paracrine MAP3K1-WNT crosstalk contributing to MD caudal elongation and FRT development. Highlights MAP3K1 deficient female mice exhibit imperforate vagina and infertilityLoss of MAP3K1 kinase activity impedes Müllerian duct (MD) caudal elongation and fusion with urogenital sinus (UGS) in embryogenesisThe MAP3K1-MAPK pathway up-regulates WNT signaling in epithelial cellsMAP3K1 deficiency down-regulates Wnt7b expression in the MD epithelium and prevents WNT activity in mesenchyme of the caudal MD.

Abstract
BACKGROUND Ovarian reserve is a crucial indicator of a woman's fertility potential, which is determined by the quality and quantity of antral follicles and oocytes. However, certain factors such as endometriosis, pelvic inflammatory disease, myoma, and the natural process of aging can lead to a poor ovarian response to stimulation, reducing a woman's chances of conceiving. OBJECTIVE To evaluate the effect of uterus congenital anomalies and uterine leiomyoma are associated on ovarian reserve. METHODS The present cross-sectional study was performed on 321 infertile women in three groups consisted of 97 infertile women with intramural uterine leiomyoma and 81 infertile women with uterine anomalies and 143 infertile women without uterine anomalies and uterine leiomyoma during 2017-2019 in Royan Center. Sampling method was continuous and available. Data collection tool in this study was a questionnaire which was in two parts of individual variables and the second part was related to ultrasound results (number of antral follicles and ovarian volume) and laboratory tests (Anti-Mullerian Hormone (AMH) and Follicle-stimulating Hormone (FSH)). Ovarian reserve parameters were measured in three groups on the third day of the cycle in both groups. Data analysis was performed using SPSS software version 21. Quantitative variables were analyzed using t-test, qualitative variables were analyzed using chi-square test. RESULTS The results of in laboratory parameters showed that there was no statistically significant difference between the three groups in FSH (2.35 ± 1.55, 2.07 ± 1.81, 2.31 ± 1.93) and AMH (6.84 ± 2.75,7.52 ± 3.14,6.93 ± 3.04), respectively (P > 0.05). The results of sonographic variables also showed that the variables include number of antral follicles in right ovarian, number of antral follicles in left ovarian have statistically significant between the three groups (5.73 ± 2.69,4.84 ± 3.14,6.66 ± 3.13), respectively (P < 0.05). CONCLUSION The results of the present study showed that uterine abnormalities and uterine leiomyoma with different mechanisms such as reduce of antral follicle numbers and the effect on uterine and ovarian blood flow lead to a decrease in ovarian reserve and infertility. Therefore, treatment and surgery can reduce these effects and improve the fertility of the affected women.

Abstract
PURPOSE To investigate the perinatal outcomes of singleton pregnant women with Müllerian anomalies (MuAs). METHODS A retrospective cohort study was conducted on singleton pregnant women with MuAs who delivered at the West China Second University Hospital between January 1, 2009 and December 31, 2020. RESULTS Four hundred fifty-seven cases of MuAs were identified, with an incidence of 0.40%. The most common anomaly was a septate uterus (38.7%). Compared to the control group, the MuAs group had significantly higher incidences of perinatal complications, including preterm deliveries (PTDs) (27.4 vs. 9.8%, P < 0.001), preterm premature rupture of membranes (PPROM) (29.1 vs. 22.5%, P = 0.001), malpresentation (34.4 vs. 5.6%, P < 0.001), abruptio placentae (4.6 vs. 1.2%, P < 0.001), placental accreta/increta (19.7 vs. 11.8%, P < 0.001), and uterine rupture (2.8 vs. 1.6%, P = 0.035). The rates of in vitro fertilization and embryo transfer (IVF-ET), foetal growth restriction (FGR), and low birth weight were also significantly higher in the MuAs group (8.3 vs. 4.5%, P < 0.001; 2.6 vs. 0.9%, P = 0.001; 3.1 vs. 1.7%, P = 0.033, respectively). In the MuAs group, the incidence of PPROM was high in cases with unicornuate uterus (31.5%), and malpresentation was as high as 42.4 and 37.0% in cases with septate and didelphys uteri, respectively. CONCLUSION The data suggest that pregnancy with MuAs may increase adverse perinatal outcomes, which calls for intensive supervision during pregnancy and delivery to reduce maternal and foetal complications. Individualized considerations should be emphasized according to the different categories of MuAs in pregnancies.

Abstract
OBJECTIVES To explore maternal and neonatal outcomes in pregnant women with bicornuate uteri. METHODS Retrospective population-based cohort study utilizing data from the Healthcare-Cost and Utilization Project-Nationwide Inpatient Sample (HCUP-NIS) from 2010 to 2014. There were 3,846,342 births between 2010 and 2014, included in the study. Six thousand and 195 deliveries were to women with bicornuate uterus. The remaining deliveries without other uterine anomalies were categorized as the reference group (n=3,840,147). RESULTS Pregnant women with bicornuate uterus were older and more likely to be obese (p=0.0001) with previous cesarean deliveries (CD) (31 vs. 17.1%, p=0.0001). After adjustment for confounders, they were more likely to experience pregnancy-induced hypertension (HTN) (aOR 1.21, 95%CI: 1.1-1.3), p=0.0001), preeclampsia (aOR 1.4, 95%CI: 1.2-1.6, p=0.0001) and placenta previa (aOR 1.7, 95%CI: 1.3-2.2, p=0.0001). Moreover, they were more likely to deliver preterm (aOR 2.8, 95%CI: 2.6-3.1, p=0.0001), deliver by CD (aOR 5, 95%CI: 3.1-4.1, p=0.0001), experience preterm pre-labor rupture of membranes (PPROM) (aOR 3.5, 95%CI: 2.6-3.1, p=0.0001), and have a placental abruption (aOR 3.0, 95%CI: 2.5-3.5, p=0.0001). There were increased risks of PPH (aOR 1.4, 95%CI: 1.2-1.6, p=0.0001), wound-complications (aOR 2.0, 95%CI: 1.5-2.7, p=0.0001), hysterectomy (aOR 2.6, 95%CI: 1.6-4.1, p=0.0001), blood-transfusion (aOR 1.7, 95%CI: 1.5-2.1, p=0.0001), and DIC (aOR 1.6, 95%CI: 1.1-2.5), p=0.014) in the group with bicornuate uteri. Also there was higher risk of SGA (aOR 2.9, 95%CI: 2.6-3.2, p=0.0001) and IUFD (aOR 2.5, 95%CI: 1.8-3.3, p=0.0001). CONCLUSIONS Bicornuate uteri can increase risks in pregnancy by many folds. Particularly risks of: premature delivery, CD, PPROM, placental abruption, hysterectomy, SGA and IUFD were increased 250-500%.

Abstract
Preterm birth defined as delivery before 37 gestational weeks, is a leading cause of neonatal and infant morbidity and mortality. Understanding its multifactorial nature may improve prediction, prevention and the clinical management. We performed an umbrella review to summarize the evidence from meta-analyses of observational studies on risks factors associated with PTB, evaluate whether there are indications of biases in this literature and identify which of the previously reported associations are supported by robust evidence. We included 1511 primary studies providing data on 170 associations, covering a wide range of comorbid diseases, obstetric and medical history, drugs, exposure to environmental agents, infections and vaccines. Only seven risk factors provided robust evidence. The results from synthesis of observational studies suggests that sleep quality and mental health, risk factors with robust evidence should be routinely screened in clinical practice, should be tested in large randomized trial. Identification of risk factors with robust evidence will promote the development and training of prediction models that could improve public health, in a way that offers new perspectives in health professionals.

Abstract
Implantation is the first step in human reproduction. Successful implantation depends on the crosstalk between embryo and endometrium. Recurrent implantation failure (RIF) is a clinical phenomenon characterized by a lack of implantation after the transfer of several embryos and disturbs approximately 10% couples undergoing in vitro fertilization and embryo transfer. Despite increasing literature on RIF, there is still no widely accepted definition or standard protocol for the diagnosis and treatment of RIF. Progress in predicting and preventing RIF has been hampered by a lack of widely accepted definitions. Most couples with RIF can become pregnant after clinical intervention. The prognosis for couples with RIF is related to maternal age. RIF can be caused by immunology, thrombophilias, endometrial receptivity, microbiome, anatomical abnormalities, male factors, and embryo aneuploidy. It is important to determine the most possible etiologies, and individualized treatment aimed at the primary cause seems to be an effective method for increasing the implantation rate. Couples with RIF require psychological support and appropriate clinical intervention. Further studies are required to evaluate diagnostic method and he effectiveness of each therapy, and guide clinical treatment.

Abstract
BACKGROUND Recurrent miscarriage (RM) affects 1%-3% of pregnancies. However, in almost 50% of cases, the cause is unknown. Increasing evidence have shown that benzo(a)pyrene [B(a)P], a representative of polycyclic aromatic hydrocarbons (PAHs), is correlated with miscarriage. However, the underlying mechanisms of B(a)P/benzo(a)pyrene-7,8-dihydrodiol-9,10-epoxide (BPDE)-induced trophoblast cell dysfunctions and miscarriage remain largely unknown. OBJECTIVE The objective was to discover the role(s) of a novel lncRNA, lnc-HZ09, in the regulation of BPDE-inhibited migration and invasion of trophoblast cells and the occurrence of miscarriage. METHOD Human trophoblast cells were treated with 0, 0.25, 0.5, 1.0, or 1.5μM BPDE with or without corresponding lnc-HZ09 silencing or overexpression. Using these cells, we evaluated cell migration and invasion, the mRNA and protein levels of members of the PLD1/RAC1/CDC42 pathway, the regulatory roles of lnc-HZ09 in PLD1 transcription and mRNA stability, and lnc-HZ09 transcription and stability. Human villous tissues were collected from RM (n=15) group and their matched healthy control (HC, n=15) group. We evaluated the levels of BPDE-DNA adducts, lnc-HZ09, and the mRNA and protein expression of members of the PLD1/RAC1/CDC42 pathway, and correlated their relative expression levels. We further constructed 0, 0.05 or 0.2mg/kg B(a)P-induced mouse miscarriage model (each n=6), in which the mRNA and protein expression of members of the Pld1/Rac1/Cdc42 pathway were measured. RESULTS We identified a novel lnc-HZ09. Human trophoblast cells treated with lnc-HZ09 exhibited less cell migration and invasion. In addition, the levels of this lncRNA were higher in villous tissues from women with recurrent miscarriage than those from healthy individuals. SP1-mediated PLD1 mRNA levels were lower, and HuR-mediated PLD1 mRNA stability was less in trophoblast cells overexpressing lnc-HZ09. However, trophoblast cells treated with MSX1 had higher levels of lnc-HZ09, and METTL3-mediated m6A methylation on lnc-HZ09 resulted in greater lnc-HZ09 RNA stability. In BPDE-treated human trophoblast cells and in RM villous tissues, MSX1-mediated lnc-HZ09 transcription and METTL3-mediated lnc-HZ09 stability were both greater. In our mouse miscarriage model, B(a)P-treated mice had lower mRNA and protein levels of members of the Pld1/Rac1/Cdc42 pathway. DISCUSSION These results suggest that in human trophoblast cells, BPDE exposure up-regulated lnc-HZ09 level, suppressed PLD1/RAC1/CDC42 pathway, and inhibited migration and invasion, providing new insights in understanding the causes and mechanisms of unexplained miscarriage. https://doi.org/10.1289/EHP10477.

ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2023; 61:99-108. [PMID: 36099518 PMCID: PMC10107309 DOI: 10.1002/uog.26073] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 08/27/2022] [Accepted: 09/05/2022] [Indexed: 05/27/2023]
Abstract
OBJECTIVES To study the reproductive outcomes of women with a unicornuate uterus and compare them to those of women with no congenital uterine anomaly. METHODS This was a single-center, retrospective cohort study. Cases were women aged at least 16 years who were diagnosed with a unicornuate uterus on transvaginal/transrectal ultrasound between January 2008 and September 2021. Controls were women with no congenital uterine anomaly matched 1:1 by age and body mass index. The primary outcome was live-birth rate. Secondary outcomes were pregnancy loss (miscarriage, ectopic pregnancy, termination of pregnancy), preterm delivery, mode of delivery and concomitant gynecological abnormalities (endometriosis, adenomyosis, fibroids). RESULTS Included in the study were 326 cases and 326 controls. Women with a unicornuate uterus had a significantly lower live-birth rate (184/388 (47.4%) vs 229/396 (57.8%); P = 0.004) and higher rates of overall miscarriage (178/424 (42.0%) vs 155/465 (33.3%); adjusted odds ratio (aOR), 2.21 (95% CI, 1.42-3.42), P < 0.001), ectopic pregnancy (26/424 (6.1%) vs 11/465 (2.4%); aOR, 2.52 (95% CI, 1.22-5.22), P = 0.01), preterm delivery (45/184 (24.5%) vs 17/229 (7.4%); aOR, 3.04 (95% CI, 1.52-5.97), P = 0.001) and Cesarean delivery (116/184 (63.0%) vs 70/229 (30.6%); aOR, 2.54 (95% CI, 1.67-3.88), P < 0.001). Rudimentary-horn pregnancies accounted for 7/26 (26.9%) ectopic pregnancies in the study group. Women with a unicornuate uterus were more likely to have endometriosis (17.5% vs 10.7%; P = 0.018) and adenomyosis (26.7% vs 15.6%; P = 0.001), but were not more likely to have fibroids compared with controls. Women with a functional rudimentary horn were more likely to have pelvic endometriosis compared to those without (odds ratio, 2.4 (95% CI, 1.4-4.1), P = 0.002). CONCLUSIONS Pregnant women with a unicornuate uterus should be classified as high risk. Removal of a functional rudimentary horn should be discussed with the patient to prevent a rudimentary-horn ectopic pregnancy. © 2022 The Authors.

Yayna AA, Ayza A, Dana WW, Desalegn A, Kassaye G, Yemaneh A, Geta A, Shote B, Gure T, Tesfaye A. A rare case report of uterine didelphys, in which one uterus carried a pregnancy while the other prolapsed, with a successful pregnancy outcome resulting in an alive-term delivery. SAGE Open Med Case Rep 2023; 11:2050313X231159505. [PMID: 36923446 PMCID: PMC10009015 DOI: 10.1177/2050313x231159505] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Accepted: 02/07/2023] [Indexed: 03/13/2023] Open
Abstract
Uterine didelphys is a rare congenital anomaly of the female reproductive organs, designated by the presence of the uterus as a pair of organs. This occurs as a result of the failure of the embryonic fusion of Müllerian ducts. Women with this abnormality have a paired uterus with two cervices and usually a double vagina. The chance of having a pregnancy in one of the pairs along with prolapse of the other is very low in a didelphic uterus. To the best of the author's knowledge, only one case of such an event has been reported so far. In this case report, we are reporting on a 28-year-old gravida four para three (all are vaginal deliveries, 2 are alive, healthy, and term deliveries without any compilation; 1 is an early neonatal death delivered at 8 months) woman who presented to our hospital with a complaint of a protruding mass per vagina for 14 days in the presence of pregnancy. After she was evaluated and investigated, she was diagnosed with pelvic organ prolapse and late-preterm pregnancy. The prolapse reduced gradually as the gestational age advanced. Cesarean section was done at the gestational age of 38 weeks plus 2 days for the indication of infected pelvic organ prolapse in labor, with the outcome of a 3000 gram male alive neonate. Intraoperatively, there was uterine didelphys, one uterus holding the pregnancy while the other was prolapsing.
