Abstract
Ovarian stimulation is a fundamental step in assisted reproductive technology (ART) with the intention of inducing ovarian follicle development prior to timed intercourse or intra-uterine insemination and facilitating the retrieval of multiple oocytes during a single in vitro fertilization (IVF) cycle. The basis of ovarian stimulation includes the administration of exogenous gonadotropins, with or without pre-treatment with oral hormonal therapy. Gonadotropin-releasing hormone agonist or antagonist is given in addition to the gonadotropins to prevent a premature rise of endogenous luteinizing hormone that would in turn lead to premature ovulation. With the advancement in technology, various stimulation protocols have been devised to cater for different patient needs. However, ovarian hyperstimulation syndrome and its serious complications may occur following ovarian stimulation. It is also evident that suboptimal ovarian stimulation strategies may have a negative impact on oogenesis, embryo quality, endometrial receptivity, and reproductive outcomes over recent years. This review describes the various forms of pre-treatment for ovarian stimulation and stimulation protocols, and aims to provide clinicians with the latest available evidence.

Eur J Obstet Gynecol Reprod Biol 2023; 289:65-73. [PMID: 37639817 DOI: 10.1016/j.ejogrb.2023.08.014] [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: 02/24/2023] [Revised: 06/01/2023] [Accepted: 08/15/2023] [Indexed: 08/31/2023]
Abstract
OBJECTIVE To conduct a systematic review andmeta-analysis of all randomized controlled trials (RCTs) that investigated whether dual triggering [a combination of gonadotropin-releasing hormone (GnRH) agonist and human chorionic gonadotropin (hCG)] of final oocyte maturation can improve the number of oocytes retrieved and clinical pregnancy rate in low or normal responders undergoing in-vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles using a GnRH-antagonist protocol. STUDY DESIGN Studies up to October 2022 were identified from PubMed, Scopus, Cochrane Library and Web of Science. The risk of bias of included studies was assessed. Dichotomous outcomes were reported as relative risks (RR), and continuous outcomes were reported as weighted mean differences (WMD) with 95% confidence intervals (CI). The primary outcomes were number of oocytes retrieved, number of mature [metaphase II (MII)] oocytes, clinical pregnancy rate and ongoing pregnancy rate; other IVF outcomes were considered as secondary outcomes. RESULTS Seven studies were identified, and 898 patients were eligible for inclusion in this meta-analysis. The results showed that the number of oocytes retrieved [WMD = 1.38 (95% CI 0.47-2.28), I2 = 66%, p = 0.003, low evidence], number of MII oocytes [WMD = 0.7 (95% CI 0.35-1.05), I2 = 42%, p < 0.0001, moderate evidence], number of embryos [WMD = 0.68 (95% CI 0.07-1.3), I2 = 67%, p = 0.03, low evidence] and number of good-quality embryos [WMD = 1.14 (95% CI 0.35-1.93), I2 = 0%, p = 0.005, moderate evidence] in the dual trigger group were significantly higher than in the hCG trigger group. The results of the ovarian response subgroup analysis showed significant differences in all of these outcomes in normal responders, and no differences in any of the outcomes in low responders, except for the number of MII oocytes. In low responders, clinical pregnancy rates may be improved in the dual trigger group [RR = 2.2 (95% CI 1.05-4.61), I2 = 28%, p = 0.04, low evidence]. CONCLUSION Dual triggering by GnRH agonist and hCG improved oocyte maturity and embryo grading for normal responders in GnRH-antagonist cycles. Dual triggering for final oocyte maturation may improve clinical pregnancy rates in low responders.

Abstract
Ovarian hyperstimulation syndrome (OHSS) is the main severe complication of ovarian stimulation for in vitro fertilization (IVF) cycles. The aim of the current study was to identify the interventions for the prevention of and reduction in the incidence and severity of OHSS in patients who undergo IVF not included in systematic reviews with meta-analyses of randomized controlled trials (RCTs) and assess and grade their efficacy and evidence base. The best available evidence for each specific intervention was identified, analyzed in terms of safety/efficacy ratio and risk of bias, and graded using the Oxford Centre for Evidence-Based Medicine (CEBM) hierarchy of evidence. A total of 15 interventions to prevent OHSS were included in the final analysis. In the IVF population not at a high risk for OHSS, follitropin delta for ovarian stimulation may reduce the incidence of early OHSS and/or preventive interventions for early OHSS. In high-risk patients, inositol pretreatment, ovulation triggering with low doses of urinary hCG, and the luteal phase administration of a GnRH antagonist may reduce OHSS risk. In conclusion, even if not supported by systematic reviews with homogeneity of the RCTs, several treatments/strategies to reduce the incidence and severity of OHSS have been shown to be promising.

Abstract
OBJECTIVE This study aimed to retrospectively analyze the cumulative pregnancy rate (PR) via multiple fresh or frozen embryo transfers (ET) in women with current, resected, or recurred endometrioma. MATERIALS AND METHODS The IVF data including oocyte pick-up (OPU) and fresh or frozen ET in women with current (37 women; 56 OPU, 18 fresh and 14 frozen ET), resected (24 women; 50 OPU, 17 fresh and 42 frozen ET), or recurred endometrioma (28 women; 49 OPU, 22 fresh and 24 frozen ET) were obtained. All cycles were performed from 2015 to 2022 in a single university hospital. RESULTS The median serum AMH level (ng/mL) was 1.44, 1.47, and 0.98, respectively. The number of total or mature oocytes, fertilized oocytes, cleavage embryos at day-3, and top-quality embryos at day-3 were all similar in the three groups. Cycles with no oocyte occurred in 2 (3.6%), 1 (2%), and 3 cycles (6.1%), respectively. Freeze-all was performed in 46.3%, 59.2%, and 47.8% of the cycles, respectively (p > 0.05). The cumulative clinical PR per total ET (43.8%, 25.4%, and 21.7%), per OPU (25%, 30%, and 20.4%), and per woman (37.8%, 62.5%, and 35.7%) were all similar in the three groups. The cumulative ongoing pregnancy and live birth rate per total ET, per OPU, and per woman were also similar in the three groups. CONCLUSION Similarity in ovarian reserve, number of oocytes, number of embryos, cumulative clinical PR, and live birth in the three endometriosis groups indicates that the IVF outcomes in the 'recurrent endometrioma' group are not inferior to 'current' or 'resected' group.

Abstract
Objectives To evaluate whether the dual trigger of ovulation with a gonadotropin-releasing hormone (GnRH) agonist and the standard dose of recombinant human chorionic gonadotropin (hCG) (dual trigger) is better than hCG alone in in vitro fertilization (IVF) cycles of patients who responded well to ovarian stimulation. Methods Between January 2013 and December 2021, 5593 antagonist cycles of patients were reviewed. This study included women who had an antral follicle count of 5 or more and exhibited a normoresponse to ovarian stimulation using the GnRH antagonist protocol, as determined by the follicular output rate (FORT). The primary outcome indicators consisted of the quantities of retrieved oocytes and mature oocytes. The secondary outcome markers included live birth rates, clinical pregnancy rates, and continued pregnancy rates. Results A total of 1244 normoresponder women who met the inclusion criteria were identified from the scanned files and subsequently enrolled in the GnRH antagonist protocol. A total of 383 cycles were observed in the group that was given the standard hCG trigger while 861 cycles were observed in the group that was given the dual trigger. The number of mature oocytes and top-quality embryos was significantly higher in the dual trigger group. The maturation rate in the hCG group was 74.8% while it was 76.9% in the dual trigger group (p=0.018). The dual trigger group exhibited an ongoing pregnancy rate of 37.6%, whereas the hCG group had a rate of 30.1% (p = 0.02). The dual trigger group exhibited a slightly higher live birth rate (34.3% vs 29.2%, p = 0.11), although this difference did not reach statistical significance. Conclusion Dual trigger of ovulation was superior to hCG alone in terms of the number of mature oocytes yielded, top quality of embryos, maturation rates, and ongoing pregnancy in IVF cycles of normoresponders having ovarian stimulation on the GnRH antagonist protocol.

J Assist Reprod Genet 2023; 40:2063-2077. [PMID: 37466846 PMCID: PMC10440333 DOI: 10.1007/s10815-023-02888-8] [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: 05/18/2023] [Accepted: 07/11/2023] [Indexed: 07/20/2023] Open
Abstract
PROPOSE The purpose of this study was to assess whether the implementation of a "dual trigger" approach, utilizing gonadotropin-releasing hormone agonist (GnRHa) and human chorionic gonadotropin (hCG) in the GnRH antagonist protocol for in vitro fertilization (IVF), leads to improved pregnancy outcomes compared to the conventional hCG trigger alone. Previous meta-analyses have not provided sufficient evidence to support the superiority of the dual trigger over the hCG trigger in fresh or frozen embryo transfer cycles. Thus, a systematic review and meta-analysis of randomized trials were conducted to provide a comprehensive evaluation of the impact of the dual trigger on pregnancy outcomes in fresh or frozen embryo transfer cycles. METHOD A systematic review and meta-analysis of randomised controlled trials (RCTs) were conducted. We searched the Medline and Embase databases for articles up to 2023 by using search terms: "dual trigger," "GnRHa," "hCG," "IVF." Eligible RCTs comparing the dual trigger with the hCG trigger were included. The primary outcome was the live birth rate (LBR) per cycle. The secondary outcomes were the number of oocytes retrieved, number of mature oocytes retrieved, implantation rate, biochemical pregnancy rate, CPR, miscarriage rate and ovarian hyperstimulation syndrome (OHSS) rate per started cycle We compared the oocyte maturation and pregnancy outcomes in the dual trigger and hCG trigger groups. In patients undergoing fresh embryo transfer (ET) and frozen-thawed ET, we also conducted a subgroup analysis to evaluate whether dual trigger improves the clinical pregnancy rate (CPR). RESULTS We included 10 randomised studies, with 825 participants in the dual trigger group and 813 in the hCG trigger group. Compared with the hCG trigger, dual trigger was associated with a significant increase in the LBR per cycle (odds ratio (OR) = 1.61[1.16, 2.25]), number of oocytes retrieved (mean difference [MD] = 1.05 [0.43, 1.68]), number of mature oocytes retrieved (MD = 0.82 [0. 84, 1.16]), and CPR (OR = 1.48 [1.08, 2.01]). Subgroup analyses revealed that dual trigger was associated with a significantly increased CPR in patients who received fresh ET (OR = 1.68 [1.14, 2.48]). By contrast, the dual trigger was not associated with an increased CPR in the patient group with frozen-thawed ET (OR = 1.15 [0.64, 2.08]). CONCLUSION The dual trigger was associated with a significantly higher number of retrieved oocytes, number of mature oocytes, CPR, and LBR in IVF than the hCG trigger. The beneficial effect for fresh ET cycles compared with frozen-thawed ET might be associated with increased endometrial receptivity. RELEVANCE After dual trigger, delaying ET due to the concern of endometrial receptivity might not be needed.

Abstract
RESEARCH QUESTION Is there any difference in clinical outcomes between a human chorionic gonadotrophin (HCG)-only trigger and a dual trigger combining gonadotrophin-releasing hormone agonist (GnRHa) and HCG in a progestin-primed ovarian stimulation (PPOS) protocol? DESIGN This retrospective cohort study included women younger than 40 years old with a normal ovarian reserve who underwent IVF/intracytoplasmic sperm injection treatment with a PPOS protocol. Participants were allocated to two groups according to the triggering medicines. The clinical outcomes were compared, with cumulative live birth rate (CLBR) being the primary outcome. RESULTS In total, 1066 women were included, 565 in the HCG-only group and 501 in the dual trigger group. Demographic parameters were comparable between the groups. Fewer oocytes were retrieved in the HCG-only trigger group (dual trigger 12.56 ± 7.12 versus HCG-only trigger 11.62 ± 6.02, P = 0.020). No significant difference was observed in the numbers of two-pronuclear embryos (7.12 ± 4.90 versus 6.76 ± 4.45, P = 0.208) and high-quality embryos (4.01 ± 3.70 versus 3.96 ± 3.32, P = 0.815). The CLBR after one complete cycle was also similar (40.72% versus 43.72%, P = 0.354). Multivariate logistic analysis confirmed that the trigger method had no association with CLBR (odds ratio [OR] 0.763, 95% confidence interval [CI] 0.578-1.005, P = 0.055) in the PPOS-treated patients. CONCLUSIONS Compared with the HCG-only trigger group, comparable embryological and clinical outcomes were achieved, although more oocytes were retrieved in the dual trigger group. This suggests that there may be no extra benefit from dual triggering, and that it should not be recommended for routine use in the general population undergoing PPOS protocols.

Reproductive outcomes of dual trigger with combination GnRH agonist and hCG versus trigger with hCG alone in women undergoing IVF/ICSI cycles: a retrospective cohort study with propensity score matching. BMC Pregnancy Childbirth 2022; 22:583. [PMID: 35869444 PMCID: PMC9308204 DOI: 10.1186/s12884-022-04899-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2022] [Accepted: 07/04/2022] [Indexed: 11/10/2022] Open
Abstract
Background Despite a large number of studies on the selection of trigger drugs, it remains unclear whether the dual trigger with human chorionic gonadotropin (hCG) and gonadotropin-releasing hormone (GnRH) agonist, compared to the trigger with hCG alone, can improve the reproductive outcome of patients undergoing assisted reproductive technology. Therefore, this study aimed to compare the laboratory and clinical outcomes of dual trigger versus single trigger. Methods In this retrospective cohort study, we evaluated 520 in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles between July 2014 and September 2020 at the Reproductive and Genetic Center of Integrative Medicine, The Affiliated Hospital of Shandong University of Traditional Chinese Medicine. All patients underwent IVF/ICSI treatment with fresh embryo transfer using the GnRH antagonist protocol. We used propensity score matching to control for confounding variables and binary logistic regression analysis to determine the correlations between trigger methods and pregnancy outcomes. After propensity score matching, 57 cycles from each group were evaluated and compared for laboratory or clinical outcomes in this retrospective cohort study. Results There was no significant difference in the number of oocytes retrieved, embryos available, top-quality embryos, or the rate of normal fertilization between the dual-trigger and single-trigger protocols, respectively. The incidence of ovarian hyperstimulation syndrome, implantation rate, biochemical pregnancy rate, clinical pregnancy rate, ectopic pregnancy rate, early miscarriage rate, and live birth rate were also similar between the two groups, while the miscarriage rate (37.0% vs. 12.5%, p = 0.045) was higher in the dual-trigger than the single-trigger group. Subsequent binary logistic regression analysis showed that age was a remarkably significant independent predictor of both clinical pregnancy rate (odds ratio = 0.90, 95% confidence interval: 0.84–0.97, p = 0.006) and live birth rate (odds ratio = 0.89, 95% confidence interval: 0.82–0.97, p = 0.005). Conclusions Therefore, dual-trigger for final oocyte maturation might increase miscarriage rate, but in terms of the laboratory and other pregnancy outcomes such as clinical pregnancy rate, early miscarriage rate or live birth rate, there was no evidence to show that dual trigger was superior to an hCG-trigger alone for patients undergoing GnRH-antagonist cycles with fresh embryo transfer. Trial registration Retrospectively registered.

Abstract
PURPOSE To evaluate the effects of adjuvant letrozole administration on outcomes of gonadotropin-releasing hormone (GnRH) antagonist cycles with intra-cytoplasmic sperm injection in POSEIDON groups 3 and 4 expected poor responder women. METHODS This study was conducted by retrospective analysis of patients with expected poor ovarian response (POSEIDON groups 3 and 4) that underwent GnRH antagonist cycles with intra-cytoplasmic sperm injection between 2010 and 2020. A total of 488 patients with letrozole co-administration and 2564 patients without any adjuvant treatment that underwent GnRH antagonist cycles within the selected period of time were included in the study. RESULTS Implantation rates, clinical pregnancy rates and live birth delivery rates were significantly higher in letrozole administered patients in comparison to controls among POSEIDON group 3 women (0.39 ± 0.46 vs 0.27 ± 0.40, p = 0.01; 46.1% vs 33%, p = 0.014; 42.7% vs 31.5%, p = 0.034, respectively). Mean total doses of gonadotropins required per cycle were significantly lower in letrozole administered patients among both POSEIDON groups 3 and 4 women (2864.65 ± 878.47 IU vs 3757.27 ± 1088.89 IU, p < 0.001; 3286.06 ± 770.16 IU vs 3666.48 ± 959.66 IU, p < 0.001, respectively). CONCLUSION Adjuvant letrozole co-administration in intra-cytoplasmic sperm injection cycles following GnRH antagonist protocol appears to improve implantation, clinical pregnancy and live birth delivery rates in women with POSEIDON group 3 expected poor ovarian response.

Abstract
OBJECTIVE Poor ovarian responders (PORs) pose a great challenge for fertility clinics worldwide. The aim of this study was to examine whether 'dual trigger' consisting of human chorionic gonadotropin (hCG) plus gonadotropin-releasing hormone agonist (GnRHa) is beneficial or not regarding implantation rate, pregnancy rate, and live birth rate for POR. METHODS This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. Risk of bias was evaluated by the Newcastle-Ottawa scale or version 2 (NOS) of the Cochrane risk-of-bias tool for randomized trials (ROB2) independently by two authors. Furthermore, RevMan version 5.4 was used to analyze the extracted data and to create an inverse-weighted summary-odds ratio (OR). RESULTS A total of 1390 studies were screened. Seven studies containing a total of 2474 POR were included. The pooled meta-analysis revealed a 1.62-fold increase in clinical pregnancy rate (OR = 1.62 [1.00, 2.62], p = .05) and a 2.65-fold increase in live birth rate (OR = 2.65 [1.66, 4.24], p < .0001) in the dual trigger group compared to hCG trigger. The pooled analysis showed no significant difference between the two groups regarding implantation rate (OR = 1.14 [0.93, 1.39], p = .21). CONCLUSIONS The meta-analysis of this study indicates that dual trigger as finale oocyte maturation is advantageous compared to hCG trigger among POR. However, large-scale, high-quality, randomized controlled trials (RCT) are required to confirm this conclusion and fully address the magnitude of this effect.

Abstract
In patients with varying hematologic disorders (thalassemia, sickle cell anemia, aplastic anemia, etc.), inherited bone marrow failure syndromes, and immune deficiencies due to a single gene disorder, the advent of stem cell transplantation (SCT) as a treatment option has allowed for significant disease improvement, and possibly cure. This specific treatment option often requires exposure to chemotherapeutic agents and sometimes whole body radiation; therefore, primary ovarian insufficiency is often sequelae of the therapy. The optimization of fertility preservation protocols within this patient population is of extreme importance. This review aims to detail the use of GnRH agonist use within this patient population, within the context of fertility preservation cycles.
