GnRH-Agonist Ovulation Trigger in Patients Undergoing Controlled Ovarian Hyperstimulation for IVF with Stop GnRH-Agonist Combined with Multidose GnRH-Antagonist Protocol
Objective: This study aimed to characterize those patients undergoing the stop gonadotropin-releasing hormone (GnRH)-agonist combined with multidose GnRH-antagonist protocol, with suboptimal response to GnRH-agonist trigger in in vitro fertilization (IVF) cycles. Design: This is a cohort study. Sett...

| description | Objective: This study aimed to characterize those patients undergoing the stop gonadotropin-releasing hormone (GnRH)-agonist combined with multidose GnRH-antagonist protocol, with suboptimal response to GnRH-agonist trigger in in vitro fertilization (IVF) cycles. Design: This is a cohort study. Setting: The study was conducted in a university hospital. Patients: All consecutive women admitted to our IVF unit from February 2020 through November 2020 who reached the ovum pick-up stage were reviewed. Interventions: Triggering final oocyte maturation by GnRH-ag alone (GnRH-ag trigger group), or combined with hCG (dual trigger group), in patients undergoing the stop GnRH-agonist combined with multidose GnRH-antagonist protocol was performed. Main Outcome Measure: The main outcome measure was LH level 12 h after the trigger. Results: Five out of the 32 patients (15.6%) demonstrated suboptimal response as reflected by LH levels |

Main Outcome Measure: The main outcome measure was LH level 12 h after the trigger. Results: Five out of the 32 patients (15.6%) demonstrated suboptimal response as reflected by LH levels <15 IU/L 12 h after GnRH-agonist trigger. Moreover, while no differences were observed in oocyte recovery rate, maturity, or embryo quality between the different study groups (GnRH-ag trigger and dual trigger groups), those achieving a suboptimal response to the GnRH-agonist trigger (post-trigger LH <15 mIU/mL) demonstrated significantly higher number of follicles and peak estradiol levels at the day of trigger, compared to those with optimal response (post-trigger LH >15 mIU/mL). Conclusions: The stop GnRH-agonist combined with GnRH-antagonist protocol enables the substitution of hCG with GnRH-ag for final oocyte maturation. However, caution should be taken in high responders, where the dual trigger with small doses of hCG (1,000–1,500 IU) should be considered, aiming to avoid suboptimal response (post-trigger LH levels <15 IU/L).</description><identifier>ISSN: 0378-7346</identifier><identifier>EISSN: 1423-002X</identifier><identifier>DOI: 10.1159/000517177</identifier><identifier>PMID: 34537779</identifier><language>eng</language><publisher>Basel, Switzerland</publisher><subject>Chorionic Gonadotropin ; Cohort Studies ; Female ; Fertilization in Vitro ; Gonadotropin-Releasing Hormone - therapeutic use ; Humans ; Ovulation ; Ovulation Induction ; Pregnancy ; Pregnancy Rate ; Research Article</subject><ispartof>Gynecologic and obstetric investigation, 2021-11, Vol.86 (5), p.427-431</ispartof><rights>2021 S.
