Hysteroscopic Management of Symptomatic Cesarean Scar Diverticulum in Patients Undergoing Frozen-Thawed Embryo Transfer: Impact on Clinical Pregnancy Rates and Pregnancy Complications. Reprod Sci 2024:10.1007/s43032-024-01642-4. [PMID: 38977643 DOI: 10.1007/s43032-024-01642-4] [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: 03/20/2024] [Accepted: 06/29/2024] [Indexed: 07/10/2024]
Abstract
This retrospective cohort study aimed to compare the clinical outcomes of patients with cesarean scar defect (CSD) undergoing frozen embryo transfer (FET) with or without hysteroscopic repair surgery. The study included 82 patients, with 48 patients in surgical group A (undergoing CSD repair) and 34 patients in surgical group B (undergoing hysteroscopic treatment for other uterine lesions). The results showed that patients in group A had a larger CSD volume and a different shape compared to group B. However, there was no significant difference in clinical pregnancy rates between the two groups. Additionally, there were no differences in miscarriage, live birth, or preterm birth rates, and no complications such as scar pregnancy or placental abnormalities were observed in either group. These findings suggest that hysteroscopic treatment of CSD in symptomatic patients undergoing FET does not increase the risk of pregnancy complications and can lead to comparable clinical pregnancy rates with asymptomatic patients. Further studies with larger sample sizes are needed to confirm these results and evaluate long-term reproductive outcomes following CSD repair.

Abstract
Pregnancies following previous caesarean section (CS) are associated with higher incidence of infections, postpartum haemorrhage and obstetric complications. The present study aimed to explore the effect of previous CS on reproductive, maternal and neonatal outcomes in women who underwent assisted reproductive techniques (ART). A systematic review and meta-analysis were conducted to assess reproductive and pregnancy outcomes following ART in women with and without a previous CS. Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines were followed. Eligible language articles written in English, published up to October 2023, were identified in Medline, Google Scholar and Science Direct databases. The quality of the included studies was assessed using the Newcastle Ottawa Scale. A total of 19 articles, reporting on 13 different outcomes met the inclusion criteria. It was revealed that women with previous CS had 9% lower clinical pregnancy rates, 13% lower live birth rates, 11% lower implantation rates and 28% lower multiple pregnancy rates compared with women who had prior natural vaginal deliveries. Additionally, previous CS was associated with an 8-fold higher risk of difficult embryo transfers. No significant differences were noted in ectopic pregnancy rates, miscarriage rates or biochemical pregnancy rates. The present systematic review and meta-analysis demonstrated that previous CS is associated with decreased prospects of clinical pregnancy, live birth and successful embryo implantation during ART. The findings of the present study underscored the need to counsel women with prior CS regarding its potential impact on ART outcomes.

Abstract
RESEARCH QUESTION Are the pregnancy outcomes (clinical, biochemical and ectopic pregnancies) of women with a history of vaginal birth and women with a history of caesarean section who underwent single euploid embryo transfer at Fakih IVF Fertility Centre comparable? DESIGN This retrospective cross-sectional chart review with multi-variate analysis, including 1157 women, compared pregnancy outcomes between women with a history of caesarean section and women with a history of vaginal birth who underwent in-vitro fertilization (IVF) at Fakih IVF Fertility Centre. All women who underwent single euploid frozen embryo transfer were included. Fresh and multiple embryo transfers were excluded. The primary outcome was clinical pregnancy, and the secondary outcomes were biochemical and ectopic pregnancies. RESULTS Regarding pregnancy outcomes, the caesarean section group had fewer clinical pregnancies than the vaginal birth group [299 (61.1 %) vs 417 (67.3 %); p = 0.0346]. The rate of ectopic pregnancy did not differ significantly between the two groups (p = 0.4320). Similarly, there was no significant difference between the two groups regarding biochemical pregnancy [caesarean section group 22 (4.3 %) vs vaginal birth group 26 (4.0 %); p = 0.8122]. CONCLUSION This study showed a decreased likelihood of clinical pregnancy in women with a history of caesarean section. No significant differences in biochemical or ectopic pregnancies were observed between the groups. These findings have practical clinical implications for counselling patients on the impact of prior caesarean sections in assisted reproduction.

Abstract
In last twenty years, the cesarean section rate has been rising in China, leading to an increased prevalence of cesarean scar defect (CSD) and secondary infertility. CSD decreases receptivity of endometrium, induces adenomyosis and endometriosis, disrupts uterine micro-environment, causes difficulty of embryo transplant operation and further pregnancy complications. For women undergoing assisted reproductive technology (ART), CSD significantly reduces embryo implantation rate, clinical pregnancy rate and live birth rate. CSD can be effectively treated by hysteroscopic surgery, laparoscopic surgery and transvaginal surgery to increase the pregnancy rate. This article reviews the research progress on the impact of CSD on the reproductive outcomes of ART, the potential factors and related treatment, to provide reference for CSD management in ART patients.

Abstract
BACKGROUND The prevalence of ectopic pregnancy after assisted reproduction is notably high, posing a significant threat to the life safety of pregnant women. Discrepancies in published results and the lack of a comprehensive description of all risk factors have led to ongoing uncertainties concerning ectopic pregnancy after assisted reproduction. OBJECTIVE This study aimed to understand the risk factors for ectopic pregnancy after in vitro fertilization-embryo transfer in the Chinese population and provide a reference for targeted prevention and treatment. METHODS A comprehensive search of the China National Knowledge Infrastructure, Wang fang Database, China Science Technology Journal Database, Chinese Biomedical Literature Database, PubMed, Web of Science, and Embase was conducted to identify relevant literature on the risk factors for ectopic pregnancy in Chinese women after assisted reproductive technology in Chinese women. A meta-analysis of the included studies was performed using Stata17. RESULTS Overall, 34 articles were included in the analysis. The risk factors for ectopic pregnancy after in vitro fertilization-embryo transfer in the Chinese population included a thin endometrium on the day of HCG administration and embryo transplantation, a history of ectopic pregnancy, secondary infertility, a history of induced abortion, polycystic ovary syndrome, decreased ovarian reserve, tubal factor infertility, cleavage stage embryo transfer, fresh embryo transfer, artificial cycle protocols, elevated estradiol levels on the day of human chorionic gonadotropin administration, a history of tubal surgery, two or more number of embryo transfers, previous pregnancy history, and a history of pelvic surgery. CONCLUSION This study clarified the factors influencing ectopic pregnancy after in vitro fertilization and embryo transfer in the Chinese population, focusing on high-risk groups. Targeted and personalized intervention measures should be adopted to prevent and detect the disease early to reduce its incidence and harm. TRIAL REGISTRATION The protocol for this view was registered in PROSPERO (CRD42023414710).

Abstract
INTRODUCTION The prevalence of Caesarean delivery is rising steadily worldwide, and it is important to identify its future impact on fertility. A number of articles have been published on this subject, but the impact of Caesarean section on reproductive outcomes is still under debate, and none of these articles focus exclusively on frozen blastocysts. OBJECTIVE The aim of this study was to evaluate the impact of a previous Caesarean delivery compared with a previous vaginal delivery on the chances of a live birth following the transfer of one or more frozen embryos at the blastocyst stage. METHODS This was a retrospective, bicentric study at the University Hospitals of Nîmes and Montpellier, conducted between January 1st, 2016 and February 1st, 2021. Three hundred and ninety women with a history of childbirth and a transfer of one or more frozen embryos at blastocyst stage were included in the analysis. The primary outcome was the number of live births. Secondary outcomes were: the rate of positive HCG, miscarriage, ectopic pregnancy and clinical pregnancy, as well as the live birth rate according to the presence or absence of an isthmocele. RESULTS Of the 390 patients included, 118 had a previous Caesarean delivery and 272 a vaginal delivery. No statistically significant differences were found for the primary (p = 0.9) or secondary outcomes. A trend towards lower live birth rates was observed in patients with isthmoceles, but this did not reach significance (p>0.9). On the other hand, transfers were more often described as difficult in the Caesarean delivery group (p = 0.011). CONCLUSION Our study found no effect of previous Caesarean delivery on the chances of live birth after transferring one or more frozen blastocysts. However, further prospective studies are needed to confirm these results.

Abstract
Objective To study the influence of the previous cesarean section on the pregnancy outcomes and perinatal outcomes in single embryo transfer (SET) cycles in an in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) setting compared to those with previous vaginal delivery (VD). In addition, the association between fertility outcomes and different cesarean scar defect (CSD) sizes was studied. Method This was a retrospective cohort study conducted in the Reproductive Center of the First Affiliated Hospital of Nanjing Medical University. A total of 4,879 patients with previous delivery history undergoing SET were included between January 2015 and April 2019. Patients were divided into the VD group and cesarean delivery (CD) group according to different modes of previous delivery. The primary outcome was live birth rate. The pregnancy outcomes of CD were analyzed as a subgroup and the relationship between pregnancy outcomes as well as the different sizes of CSD were explored by logistic regression analysis. Results There were no significant differences in live birth rate, clinical pregnancy rate, and miscarriage rate between the CD group and VD group. The incidence rates of pregnancy complications such as pregnancy hypertension, gestational diabetes mellitus, placenta abnormalities, premature rupture of membrane, and postpartum hemorrhage were similar in the two groups. Live birth rate was significantly lower in the CSD group (23.77% vs 37.01%, aOR: 0.609, 95% CI: 0.476-0.778) comparing to patients without CSD. There were also significant differences in clinical pregnancy rate (37.52% vs 47.64%, aOR: 0.779, 95%CI: 0.623-0.973) and miscarriage rate (34.55% vs 20.59%, aOR: 1.407, 95%CI:1.03-1.923). Large size CSD significantly decreased live birth rate (13.33% vs 26.29%, aOR: 0.422, 95%CI: 0.197-0.902) and clinical pregnancy rate (25.33% vs 40.09%, aOR: 0.503, 95%CI: 0.272-0.930) compared with small size CSD. Conclusion For women with previous cesarean sections, the pregnancy outcomes were similar to those with previous VD without increased perinatal complications following SET. The presence of CSD was associated with a marked reduction in live birth rate, especially in patients with large size CSD.

Abstract
OBJECTIVE To investigate the efficacies of three cycle regimens in women receiving frozen embryo transfer with a history of cesarean section: natural cycle treatment, hormone replacement therapy and treatment with gonadotropin-releasing hormone agonist. DESIGN Retrospective cohort study. METHODS patients (N = 6,159) with a history of caesarean section who fulfilled the inclusion criteria were enrolled in the study from January 2014 to December 2019 at the CITIC-Xiangya Hospital of Reproduction and Genetics. Reproductive outcomes of patients in the natural cycle (n = 4,306) versus hormone replacement therapy (n = 1,007) versus gonadotropin-releasing hormone agonist + hormone replacement therapy groups (n = 846) were compared. Continuous data were analyzed using Student's t-test, and categorical variables were analyzed using the χ2 test. Multivariable logistic regression was used to evaluate the possible relationships between the types of endometrial preparation and pregnancy outcomes after adjusting for confounding factors. RESULTS The unadjusted odds of the miscarriage rate of singleton pregnancies were significantly higher in the hormone replacement therapy compared with the natural cycle (25.5% versus 20.4%, respectively). After adjusting for possible confounding factors, the early miscarriage rate and the miscarriage rate of singleton pregnancies remained significantly higher in the hormone replacement therapy than the natural cycle. The clinical pregnancy rates in the natural cycle, hormone replacement therapy and gonadotropin- releasing hormone agonist + hormone replacement therapy of women with a history of cesarean section was 48.8%, 48% and 47.1%, respectively, and the live birth rates were 37%, 34.1% and 35.7%, respectively. CONCLUSIONS In women undergoing frozen embryo transfer with a history of cesarean section, hormone replacement therapy for endometrial preparation was associated with a higher early miscarriage rate, albeit after statistical adjustment for confounding factors. However, the risk observed was little and did not influence the overall reproductive performances.

Abstract
INTRODUCTION Cesarean section affects subsequent spontaneous pregnancies because of implantation issues. However, its impact on post-embryo transfer pregnancies is still debated. This review aimed to evaluate the impact of a previous cesarean section on fertility and pregnancy outcomes of women undergoing fresh or frozen embryo transfer. MATERIAL AND METHODS MEDLINE, Scopus, ClinicalTrials.gov, Scielo, EMBASE, Cochrane Library at the CENTRAL, and LILACS were searched from inception to February 2021. Studies were included if they evaluated reproductive or pregnancy outcomes after fresh or frozen embryo transfer in infertile women with a previous cesarean section relative to women with a previous vaginal delivery. Random-effect meta-analyses to calculate risk ratio (RR) or mean differences with 95% confidence intervals (CI) followed by subgroup analysis for fresh and frozen embryo transfer were performed. Risk of bias and quality assessment were conducted using Newcastle-Ottawa scale and GRADE criteria. The review was registered in the International Prospective Register of Systematic Reviews (CRD42021226297). RESULTS Ten studies, with data provided for 13 696 participants, were eligible. For embryo transfers after cesarean section, compared with vaginal delivery, there was a significant reduction of the live birth rate (RR 0.88, 95% CI 0.79-0.99) and biochemical pregnancy rate (RR 0.89, 95% CI 0.82-0.96). No statistically significant differences were found for clinical pregnancy rate (RR 0.92, 95% CI 0.84-1.02), ectopic pregnancies (RR 1.00, 95% CI 0.68-1.46), pregnancy loss (RR 1.05, 95% CI 0.94-1.18), multiple pregnancies (RR 0.80, 95% CI 0.63-1.02), stillbirths (RR 0.86, 95% CI 0.27-2.69), birth defects (RR 1.71, 95% CI 0.49-5.96) or birthweight (mean difference 46.82, 95% CI -40.16 to 133.80). Subgroup analysis revealed an increased risk for preterm birth in post-cesarean section fresh embryo transfer pregnancies (RR 1.59, 95% CI 1.16-2.19). CONCLUSIONS Low-grade evidence shows that post-embryo transfer pregnancies in infertile women who had a previous cesarean delivery result in reduced biochemical pregnancy and live birth rates relative to women with a previous vaginal delivery. An increased risk for preterm birth is notable in post-fresh embryo transfer pregnancies.

Caesarean section defects may affect pregnancy outcomes after in vitro fertilization-embryo transfer: a retrospective study. BMC Pregnancy Childbirth 2021; 21:487. [PMID: 34229640 PMCID: PMC8261987 DOI: 10.1186/s12884-021-03955-7] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 05/31/2021] [Indexed: 11/10/2022] Open
Abstract
Background Caesarean section rates are rising worldwide. One adverse effect of caesarean section reported in some studies is an increased risk of subfertility. Only a few studies have assessed the relationship between the previous mode of delivery and in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) reproductive outcomes. In this study, we primarily investigated the impact of a history of caesarean section with or without defects on IVF/ICSI-ET outcomes compared to a vaginal delivery history. Methods This retrospective study included 834 women who had a IVF or ICSI treatment at our centre between 2015 and 2019 with a delivery history. In total, 401 women with a previous vaginal delivery (VD) were assigned to the VD group, and 433 women with a history of delivery by caesarean section were included, among whom 359 had a caesarean scar (CS) without a defect and were assigned to the CS group and 74 had a caesarean section defect (CSD) and were assigned to the CSD group. Baseline characteristics of the three groups were compared and analysed. Binary logistic regression analyses were performed to explore the association between clinical outcomes and different delivery modes. Results There were no significant differences in the live birth rate, biochemical pregnancy rate, clinical pregnancy rate, mean implantation rate or abnormal pregnancy rate between the CS and VD groups However, the live birth rate and mean implantation rate in the CSD group were significantly lower than those in the VD group (21.6 vs 36.4%, adjusted OR 0.50 [0.27–0.9]; 0.25 ± 0.39 vs 0.35 ± 0.41, adjusted OR 0.90 [0.81–0.99]). Among women aged ≤ 35 years, the subgroup analyses showed that the live birth rate, biochemical pregnancy rate, clinical pregnancy rate, and mean implantation rate in the CSD group were all significantly lower than those in the VD group (21.4 vs 45.8%, adjusted OR 0.35[0.15 ~ 0.85]; 38.1 vs 59.8%, adjusted OR 0.52[0.24–0.82]; 31.0 vs 55.6%, adjusted OR 0.43[0.19–0.92]; 0.27 ± 0.43 vs 0.43 ± 0.43, adjusted OR 0.85[0.43 ± 0.43]). For women older than 35 years, there was no statistically significant difference in any pregnancy outcome among the three groups. Conclusions This study suggested that the existence of a CS without a defect does not decrease the live birth rate after IVF or ICSI compared with a previous VD. However, the presence of a CSD in women, especially young women (age ≤ 35 years), significantly impaired the chances of subsequent pregnancy.

Abstract
STUDY OBJECTIVE To evaluate whether the presence of an ultrasonographic visible isthmocele has an impact on the chance of pregnancy in women undergoing embryo transfer. DESIGN Age-matched retrospective study. SETTING Private-assisted reproductive center. PATIENTS The study included a total of 150 patients with a history of cesarean delivery with 75 isthmocele cases and 75 controls. All patients underwent embryo transfer from January 2017 through June 2018. The diagnosis of isthmocele was based on transvaginal ultrasound assessment. Isthmocele was defined as an anechoic indentation on the previous cesarean scar at the midsagittal plane, with a depth of >1 mm. INTERVENTIONS Embryo transfer. MEASUREMENTS AND MAIN RESULTS The groups were similar in patient and treatment characteristics. The live birth rate was 44% in the isthmocele group and 46.7% in the control group (odds ratio [OR] 0.89; 95% confidence interval [CI], 0.47-1.71; p = .743). The clinical pregnancy rates were 49.3% and 50.7%, respectively (OR, 0.94; 95% CI, 0.50-1.79; p = .870). The miscarriage rate was greater in the isthmocele group (8%) than in the control group (4%); however, it did not reach statistical significance (OR, 2.09; 95% CI, 0.50-8.67; p = .302). The multiple pregnancy rate was similar between the groups (8% vs 5.3%, respectively; OR, 1.54; 95% CI, 0.41-5.70; p = .513). The groups were also similar in ectopic pregnancy rates (p = .560). These outcomes remained similar when adjusted for potential confounders on the regression analysis. CONCLUSION Isthmocele does not seem to have a significant impact on the chance of pregnancy in assisted reproductive treatment settings. However, the embryo transfer procedure may be more difficult in the presence of an isthmocele.
