IntroductionThis study compared, in high responders undergoing IVF treatment, GnRH agonist-only trigger and dual trigger on oocyte retrieval rate and cumulative live birth rate (LBR). The aim was to determine if the GnRH agonist-only triggers had provided outcomes comparable to dual trigger, while minimizing the risk of ovarian hyperstimulation syndrome (OHSS).Materials and methodsA retrospective, matched case-control study was conducted at Taichung Veterans General Hospital, Taiwan, including women who underwent IVF/ICSI between January 1, 2014, and December 31, 2022. Inclusion criteria were: GnRH antagonist protocol and estrogen level >3,000 pg/ml on trigger day. Exclusion criteria were: immune/metabolic diseases, donated oocytes, and mixed stimulation cycles. Propensity score matching was applied to balance age, AMH level, and oocyte number between the GnRH agonist-only and dual trigger groups. Outcomes were analyzed for patients who had complete treatment cycles, focusing on oocyte retrieval rate and cumulative LBR.ResultsWe analyzed 116 cycles in the agonist-only group, and 232 cycles in the dual trigger group. No inter-group difference was found in their age, BMI, and AMH levels. The dual trigger group had a higher oocyte retrieval rate (93% vs. 80%; p

Objective: To evaluate the efficacy and safety of dinoprostone tablet and continuous vaginal insert (Propess®) in low-risk nulliparous women at term with insufficient cervical ripening receiving elective induction. Materials and methods: A retrospective study was conducted between March 2020 and February 2022 and included 230 women who underwent elective induction with dinoprostone tablet or vaginal insert. The primary endpoint was failure of induction. Secondary endpoints included time to vaginal delivery, vaginal delivery rate, as well as maternal and neonatal complications and adverse outcomes. Results: No statistically significant differences were found between the two groups regarding the main outcome measures; however, the high responders had a significant higher proportion of hyperstimulation and non-reassuring fetal status. The high responder in the Propess group was statistically significant younger (31.68 ± 4.73 vs. 33.82 ± 4.39, p = 0.027), while they had a significantly lower BMI at delivery time of the tablet group (24.49 ± 2.24 vs. 27.42 ± 4.32, p = 0.024). Factors associated with success of vaginal delivery within 24 h (p = 0.015, OR = 0.9, 95%CI = 0.82–0.98) and the Cesarean section (p

Abstract Although numerous studies have attempted to establish the relationship between adenomyosis and infertility, no consensus has emerged. Our aim was to investigate whether adenomyosis and endometriosis affected IVF outcomes in our patients. This was a retrospective study of 1720 patients from January 2016 to December 2019. In total, 1389 cycles were included: 229 cycles in the endometriosis group (group E), 89 cycles in the adenomyosis group (group A), 69 cycles in the endometriosis and adenomyosis group (group EA), and 1002 cycles in the control group (group C). Most patients in groups A and EA received GnRH agonist treatment before FET. The 1st FET live birth rates (LBR) were 39.3%, 32.1%, 25% and 48.1% in groups E, A, EA, and C. The miscarriage rates were 19.9%, 34.7%, 39%, and 17.6%. The per retrieval cycle cumulative live birth rates (cLBRs) in patients

BackgroundThe role of luteinizing hormone (LH) in controlled ovarian hyperstimulation (COH) requires more evidence for its efficacy. Several studies compared recombinant human LH (r-hLH) or human menopausal gonadotropin (hMG) in combination with recombinant human follicle-stimulating hormone (r-hFSH) but lack the results with GnRH-antagonist protocol and in Asians.MethodsThis is a retrospective, single-center study inspecting women receiving GnRH antagonist protocol and r-hFSH+hMG or r-hFSH+r-hLH regimen for over five days for COH in the in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycle in Taiwan from 2013 to 2018. The outcomes of IVF/ICSI cycles were analyzed after propensity score matching between the two groups. A subgroup analysis was conducted in cycles in which women underwent their first embryo transfer (ET), including fresh ET and frozen ET (FET).ResultsWith a total of 503 cycles, the results revealed that the r-hFSH+r-hLH group performed better in terms of numbers of oocytes retrieved (r-hFSH+hMG vs. r-hFSH+r-hLH, 11.7 vs. 13.7, p=0.014), mature oocytes (8.7 vs. 10.9, p=0.001), and fertilized oocytes (8.3 vs. 9.8, p=0.022), while other outcomes were comparable. The analysis of first ET cycles also showed similar trends. Although the implantation rate (39% vs. 43%, p=0.37), pregnancy rate (52% vs. 53%, p=0.90), and live birth rate (39% vs. 45%, p=0.19) were not significantly different, the miscarriage rate was higher in the r-hFSH+hMG group than the r-hFSH+r-hLH group (26% vs. 15%, p

Object: We have previously reported that cumulative live birth rates (CLBRs) are higher in the freeze-all group compared with controls (64.3% vs. 45.8%, p = 0.001). Here, we aim to determine if the freeze-all policy is more cost-effective than fresh embryo transfer followed by frozen-thawed embryo transfer (FET). Materials and methods: The analysis consisted of 704 ART (Assisted reproductive technology) cycles, which included in IVF (In vitro fertilisation) and ICSI (Intra Cytoplasmic Sperm Injection) cycles performed in Taichung Veterans General Hospital, Taiwan between January 2012 and June 2014. The freeze-all group involved 84 patients and the fresh Group 625 patients. Patients were followed up until all embryos obtained from a single controlled ovarian hyper-stimulation cycle were used up, or a live birth had been achieved. The total cost related to treatment of each patient was recorded. The incremental cost-effectiveness ratio (ICER) was based on the incremental cost per couple and the incremental live birth rate of the freeze-all strategy compared with the fresh ET strategy. Probabilistic sensitivity analysis (PSA) and a cost-effectiveness acceptability curve (CEAC) were performed. Results: The total treatment cost per patient was significantly higher for the freeze-all group than in the fresh group (USD 3419.93 ± 638.13 vs. $2920.59 ± 711.08 p

Objective: Microbial contamination of ART culture media is rare but serious. We examined our own experience and conducted a review of the literature with a view to preventing its occurrence and recurrence. Case report: A total of 12 cases were recorded during January 2006 to March 2019. The contaminations were caused by semen and were shown to be bacteria that were resistant to the prophylactic antibiotics used in the medium. After the procedures were cancelled due to contaminations, nine husbands received antibiotic treatment, while nine couples changed over to the ICSI program. Eventually, eight couples concluded the study with live birth deliveries, and there was no recurrence of contamination. Conclusion: ART laboratories should preserve all sperm suspension samples until embryo transfer has been completed for the purpose of checking whether contamination has occurred. In addition to antibiotic treatment, implementation of the ICSI procedure during the next ART cycle has already been proven to be effective. In the future, the zona-removal technique may be considered as another potential option.

Objective: There are increasing concerns regarding the adverse effects associated with control ovarian hyperstimulation (COH) in both endometrial and uterine environments. With the “segmentation treatment policy” of assisted reproductive techniques (ART), endometrial problems may be obviated through embryo cryopreservation. However, it remains unclear if the “freeze-all policy” offers a better outcome when compared with fresh embryo transfer (ET). To clarify this, we compared the cumulative live birth rates (CLBRs) between these two patient populations. Materials and methods: This is a retrospective study on 853 patients undergoing ovarian stimulation and ART (including IVF/ICSI) during the period from January 2012 to June 2014 in Taichung Veterans General Hospital, Taiwan, ROC. We followed up with these patients through to November 2016. Patients whose embryos were not completely transferred back were excluded. The study group ('freeze-all') included 84 patients whose cycles were performed initially without fresh ET, but were later given frozen-thawed ET. The control group (‘fresh ET’) had 625 patients whose cycles were performed with fresh ET, followed by frozen-thawed ET. Basic parameters and CLBRs were statistically compared between these two groups. Results: The CLBRs in the study group were significantly higher than those in the control group (64.3% vs. 45.8%, p = 0.001). Subgroup analysis revealed that when the number of oocyte pick up (OPU) is between 4 and 15, the CLBRs in the study group were significantly better (58.3% vs. 40.9%, p = 0.042). For those with OPU 15 the CLBRs were similar in these two groups (OPU 15: study vs. control 85.7% vs. 80.8% respectively, p = 0.625) Conclusion: The Freeze-all policy improved the ART outcome for normal responders.

Objective: The purpose of this study was to describe our preliminary experience of the efficacy and safety of a conservative strategy for abnormally invasive placenta. Materials and Methods: A retrospective review of eight pregnant women with abnormally invasive placenta (one with placenta previa accrete, three with placenta previa increta, and four with previa percreta) was performed. The diagnosis was made by prenatal ultrasonography, and was confirmed by operative and histopathological findings. Patients who desired future fertility or who had extensive diseases were selected as candidates after panel meeting. Conservative management after obtaining informed consent was defined by a primary cesarean delivery before 35 weeks of gestation with the abnormally adherent placenta left in situ, partially or totally. The primary outcome was successful uterine preservation. The secondary outcome was severe maternal morbidity including sepsis, coagulopathy, immediate or delayed hemorrhage bladder injury, and fistula. Results: Among the eight patients, the mean age was 34 ± 3 years (range, 30–40 years). All women had risk factors, such as placental previa, previous cesarean delivery and/or dilation & curettage, for abnormally invasive placenta. Seven women underwent planned cesarean delivery at the mean gestation age of 34 weeks (range, 31–37 weeks). One woman received hysterotomy at 18 weeks. In our series, the uterus was preserved in only two cases (25%), one who received hysterotomy at a relatively young gestational age and another who had mild disease. Mean maternal blood loss during primary cesarean delivery was 528 ± 499 ml (range, 100 ml–1,500 ml). Severe maternal morbidity was recorded in seven out of eight patients (87.5%). Conclusion: In this small series, we observed a low successful uterine preservation rate and a high maternal complication rate. We recommend that primary cesarean hysterectomy should be used as the treatment of choice for mild to severe abnormally invasive placenta. Conservative management should be reserved for women with a strong fertility desire and women with extensive disease that precludes primary hysterectomy due to surgical difficulty.

The cumulative pregnancy rate was significantly higher in the r-hFSH+r-hLH group (53% vs. 64%, p=0.02). No significant difference in rates of ovarian hyperstimulation syndrome (OHSS) was observed. Conclusion: The results support the hypothesis that the treatment of r-hLH+rhFSH improves COH clinical outcomes in the IVF/ICSI cycle. [ABSTRACT FROM AUTHOR]

Objectives: The purpose of this study was to investigate the efficacy and safety of temporary prophylactic intravascular balloon occlusion of the common iliac arteries (CIA) before planned cesarean hysterectomy for controlling operative blood loss in abnormal placentation. Materials and methods: A retrospective study of 13 pregnant women at risk for placenta accreta identified using sequential obstetric ultrasonography and magnetic resonance imaging from January 2007 to December 2009 was performed. Temporary prophylactic intravascular balloon catheterization of the bilateral CIA before cesarean hysterectomy was performed by interventional radiologists. The maximum duration of occlusion time of CIA must not exceed 60 minutes. The primary outcome for this study included estimated blood loss and secondary outcomes included the development of thromboembolism, disseminated intravascular coagulation and surgical complications. Results: Among these13 patients, the mean age of the patients was 32.8 ± 0.7 years (range 29–37 years). The mean gestational age at cesarean hysterectomy was 32.2 ± 0.9 weeks (range 28–36 weeks), and the mean intraoperative blood loss was 1902.3 ± 578.8 mL (range 500–8000 mL). Operative bleeding was controlled by conservative treatment without additional surgery in two cases. Importantly, two patients (15.8%) had severe complications possibly related to the interventional procedure. One patient was noted to have a popliteal artery thrombosis. A second patient had an external iliac artery thrombosis with 80–90% occlusion. Both patients required antithrombotic treatment without sequelae. Conclusion: With limited experience in this small series, we observed a statistically significant reduction in operative blood loss after the use of temporary prophylactic balloon occlusion of the CIA technique compared with historical controls of similar demographic characteristics previously published (1902.3 ± 578.8 mL, range 500–8000 mL vs. 4445.7 ± 996.48 mL, range 1040–15,000 mL, p = 0.0402). Additionally, two patients had arterial thrombosis. These preliminary findings are based on a small number of patients, and therefore further investigation is needed to determine the effectiveness and safety of this new technique.
