Live birth rate of gonadotropin-releasing hormone antagonist versus luteal phase gonadotropin-releasing hormone agonist protocol in IVF/ICSI: a systematic review and meta-analysis. Expert Rev Mol Med 2023; 26:e2. [PMID: 38095077 PMCID: PMC10941349 DOI: 10.1017/erm.2023.25] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2023] [Revised: 08/18/2023] [Accepted: 10/25/2023] [Indexed: 02/15/2024]
Abstract
In vitro fertilization (IVF) and embryo transfer and intracytoplasmic sperm injection (ICSI) have allowed millions of infertile couples to achieve pregnancy. As an essential part of IVF/ICSI enabling the retrieval of a high number of oocytes in one cycle, controlled ovarian stimulation (COS) treatment mainly composes of the standard long gonadotrophin-releasing hormone agonist (GnRH-a) protocol and the gonadotrophin-releasing hormone antagonist (GnRH-ant) protocol. However, the effectiveness of GnRH-ant protocol is still debated because of inconsistent conclusions and insufficient subgroup analyses. This systematic review and meta-analysis included a total of 52 studies, encompassing 5193 participants in the GnRH-ant group and 4757 in the GnRH-a group. The findings of this study revealed that the GnRH-ant protocol is comparable with the long GnRH-a protocol when considering live birth as the primary outcome, and it is a favourable protocol with evidence reducing the incidence of ovarian hyperstimulation syndrome in women undergoing IVF/ICSI, especially in women with polycystic ovary syndrome. Further research is needed to compare the subsequent cumulative live birth rate between the two protocols among the general and poor ovarian response patients since those patients have a lower clinical pregnancy rate, fewer oocytes retrieved or fewer high-grade embryos in the GnRH-ant protocol.

Abstract
OBJECTIVE To evaluate the efficacy of manifold ovarian stimulation protocols for patients with poor ovarian response. METHODS PubMed, Embase, Cochrane Library and Web of Science were systematically searched until February 14, 2021. Primary outcomes included clinical pregnancy rate per initiating cycle and low risk of cycle cancellation. Secondary outcomes included number of oocytes retrieved, number of metaphase II (MII) oocytes, number of embryos obtained, number of transferred embryos, endometrial thickness on triggering day and estradiol (E2) level on triggering day. The network plot, league table, rank probabilities and forest plot of each outcome measure were drawn. Therapeutic effects were displayed as risk ratios (RRs) or mean differences (MDs) with 95% confidence intervals (CIs). RESULTS This network meta-analysis included 15 trials on 2173 participants with poor ovarian response. Delayed start GnRH antagonist was the best regimen in terms of clinical pregnancy rate per initiating cycle (74.04% probability of being the optimal), low risk of cycle cancellation (75.30%), number of oocytes retrieved (68.67%), number of metaphase II (MII) oocytes (97.98%) and endometrial thickness on triggering day (81.97%), while for E2 level on triggering day, microdose GnRH agonist (99.25%) was the most preferred. Regarding number of embryos obtained and number of transferred embryos, no statistical significances were found between different ovarian stimulation protocols. CONCLUSION Delayed start GnRH antagonist and microdose GnRH agonist were the two superior regimens in the treatment of poor ovarian response, providing favorable clinical outcomes. Future investigation is needed to confirm and enrich our findings.

Abstract
Background: Treating patients with a history of poor ovarian response (POR) presents many challenges for the clinician. Poor in vitro fertilization (IVF) outcomes are a common end result. The aim of this article is to provide a detailed description of an ultralong estrogen priming (ULEP) cycle in the treatment of patients with a history of POR and to compare the outcomes to matched controls which were treated with other IVF protocols. Methods: In a retrospective study, 50 patients who meet the Bologna criteria for POR were treated with 50 ULEP cycles. The results of these cycles were compared to 50 matched controls, who were treated with other IVF protocols. Results: Patients who underwent the ULEP cycles required 3.2 more days of controlled ovarian hyperstimulation (COH) and required an extra 579 IU of follicle-stimulating hormone (FSH). The ongoing pregnancy rates per transfer were significantly greater in the ULEP group (35.1% vs. 9.1%, OR 5.4, 95% CI 1.4-21.2, p = 0.005) and per cycle started (26% vs. 6%, OR 5.5, 95% CI 1.5-20.8, p = 0.003). Conclusions: Even though the ULEP cycle is long and demanding for the patients, the outcomes suggest that this treatment regime offers a viable alternative in patients with a history of POR.

Abstract
To evaluate the effectiveness of delay start protocol in improving the success of in vitro fertilization (IVF) in poor responders according to Bologna's criteria. Only randomized controlled trial (RCT) of infertile women undergoing a single IVF/ICSI cycle with ovarian stimulation protocol based on daily injections with delay start protocol or a conventional antagonist protocol were included in this systematic review and meta-analysis. The review protocol was registered in PROSPERO before starting the data extraction (CRD42019128284). Primary outcome was clinical pregnancy rate. Ongoing pregnancy rate, miscarriage rate, number of oocytes, number of MII oocytes, stimulation length, gonadotropin amount and cancellation rate were considered as secondary outcomes. Four randomized controlled trials were included with a total number of 380 participants. 189 patients were included in the delayed start protocol and 191 were allocated to the comparison group. The results showed a significant higher clinical pregnancy rate (CPR) in patients allocated to the intervention. Data from all studies failed to detect a statistical difference between groups in terms of ongoing pregnancy rate (OPR), miscarriage rate (MR), Total-Oocyte, MII-Oocyte and Total-Embryos. Gonadotropin amount (GA) was significantly lower in the intervention group in comparison to controls, with no difference in stimulation length (SL) and cancelled cycle (CC). Delayed start GnRH-antagonist protocol may reduce GA and improve CPR in poor ovarian responder according to Bologna criteria.

Does the "delayed start" protocol with gonadotropin-releasing hormone antagonist improve the pregnancy outcome in Bologna poor responders? a randomized clinical trial. Reprod Biol Endocrinol 2018; 16:124. [PMID: 30593268 PMCID: PMC6311084 DOI: 10.1186/s12958-018-0442-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2018] [Accepted: 12/10/2018] [Indexed: 01/03/2023] Open
Abstract
BACKGROUND Recently, a novel approach with delaying the start of controlled ovarian stimulation along with gonadotropin-releasing hormone (GnRH) antagonist pretreatment for 7 days after estrogen priming for further suppression of endogenous follicle stimulating hormone (FSH) during the early follicular phase, resulting in more FSH-responsive follicles and thus improving synchronous follicular development was introduced. Two clinical trials have examined this strategy and reported controversial results. This study aimed to compare the effect of delayed-start GnRH antagonist protocol and standard GnRH antagonist in patients with poor ovarian response (POR) undergoing in vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI). METHODS This randomized clinical trial was conducted at infertility department of Royan Institute from January 2017 to June 2018. Poor ovarian response was defined according to the Bologna criteria. The eligible women were randomly allocated into an experimental and control groups. In experimental group, patients received delayed-start GnRH antagonist protocol with estrogen priming followed by early follicular-phase GnRH antagonist treatment for 7 days before ovarian stimulation with gonadotropin and in control group, patients treated with estrogen priming antagonist protocol. IVF/ICSI outcomes were compared between groups. RESULTS Among all the 250 patients examined 156 women were eligible for study and finally 120 patients were allocated to intervention (n = 60) and control (n = 60) groups. Demographic characteristics and hormonal profiles of the patients did not differ between groups. The statistical analysis showed that there were significant differences between groups regarding the total dose of used gonadotropins (P < 0.001), stimulation duration (P < 0.001), number of retrieved oocytes (P = 0.01) and top quality embryo (P < 0.001) and also cancellation (P = 0.002) and fertilization rates (P = 0.002). CONCLUSION On the basis of present results the delayed-start protocol in poor responders can improve the fertilization rate and quality of embryos and reduce the cycle cancellation but have no significant effect on clinical pregnancy rate; however, larger randomized clinical trials are required to compare it with other protocols.
