GnRH = gonadotropin-releasing hormone; IVF = in vitro fertilization. In regular responders, the usage of GnRH antagonist versus very long GnRH agonist protocols was connected with a statistically significant reduced amount of OHSS, without evidence of a notable difference in live delivery prices [45]. GnRH antagonist protocols have already been shown to bring about better results than GnRH agonists in individuals with poor prognosis [52,53]. Inside a meta-analysis of six medical tests evaluating GnRH antagonist versus GnRH agonist protocols in poor ovarian responders in IVF/intracytoplasmic sperm shot (ICSI) cycles Franco et al. [54] indicated no difference between GnRH antagonists and agonists regarding routine cancellation price, amount of mature oocytes, and medical being pregnant price per routine initiated, per oocyte retrieval, and per embryo transfer. Al-Inany et al. [45] discovered no factor following the usage of GnRH antagonist and agonist protocols in a recently available Cochrane review. In oocyte donation [55] and embryo transfer [56] cycles, the replacement of GnRH agonist having a GnRH antagonist got no effect on the implantation and pregnancy rates. Higher being pregnant rates had been also shown inside a gonadotropin intrauterine insemination routine than in a routine where no treatment occurred [57].

Optimal usage of GnRH antagonists in varied treatment circumstances First-line treatmentGnRH antagonists have already been been shown to be a highly effective treatment in ladies undergoing managed ovarian excitement for IVF in multiple meta-analyses and medical studies. In the organized review and meta-analyses by Kolibianakis et al. [23], it was shown that the probability of live birth was not dependent on the type of GnRH analog used for the suppression of premature LH rises (odds ratio 0.86; 95% confidence interval 0.72-1.02). In a more recent systematic review, Al-Inany et al. [45] also reported that there was no significant difference in live birth rates following a GnRH antagonist or GnRH agonist protocol (odds ratio 0.86, 95% confidence interval 0.69-1.08). In a retrospective review of patients with good prognosis undergoing their first IVF cycle, Johnston-MacAnanny et al. [59] showed that clinical and ongoing pregnancy rates and implantation rates were similar in 755 good responder patients undergoing a GnRH agonist protocol and 378 good responder patients undergoing a GnRH antagonist protocol during their first cycle of IVF. Borm and Mannaerts [8] evaluated the efficacy and safety of ganirelix in 730 women undergoing ovarian stimulation with rFSH. The patients were randomized in a 2:1 ratio to either 0.25 mg ganirelix or buserelin (the trial was designed as a noninferiority study using a long protocol of intranasal buserelin and rFSH as a reference treatment). Ganirelix in comparison with buserelin resulted in a shorter duration of treatment (5 vs 26 days). Comparison of the number and size of follicles indicated that in the ganirelix group, the final number of follicles on the day of hCG administration, was smaller (10.7 vs 11.8) and produced less peak estradiol concentration (1190 vs 1700 pg/ml) than the buserelin group. The ganirelix regimen resulted in the recovery of good-quality oocytes, as reflected by the high fertilization rate (62.1%), and a similar number of good-quality embryos (3.3), as the reference group (3.5). The clinical outcome (defined as the ongoing pregnancy rate per attempt) was good (20.3%), although pregnancy rates were found to be slightly higher in the reference group (25.7%). Interestingly, the ongoing pregnancy rate per attempt for patients treated at study sites (n = 10) that had previous experience with the ganirelix regimen was similar, that is, 24.2% IFN alpha-IFNAR-IN-1 hydrochloride in the ganirelix group vs 23.6% in the buserelin group.

In normal responders, the use of GnRH antagonist versus long GnRH agonist protocols was associated with a statistically significant reduction of OHSS, with no evidence of a difference in live birth rates [45].
