Cycle outcomes of dual trigger (GnRH agonist plus hCG) versus human chorionic gonadotropin trigger alone in POSEDION group 3-4 poor-responders and normo-responders: A prospective randomized study
Özet
Introduction: Recently, dual trigger was proposed in an attempt to improve in vitro fertilization (IVF) cycle outcomes in poor and normo-responder patients (PR and NR, respectively). The study's aim was to compare cycle outcomes of dual trigger versus human chorionic gonadotropin (hCG) trigger in NRs and POSEIDON group 3/4 (PG 3/4) PRs.Material and Methods: A prospective randomized controlled trial included PG 3/4 PRs and NRs undergoing IVF using a gonadotropin-releasing hormone (GnRH) antagonist protocol. PRs and NRs were divided into two sub-groups: (1) study groups in both arms received dual trigger and (2) control groups received only HCG.Results: Two-hundred twenty-five women participated in the study. The mean patient age was significantly higher in the dual trigger group versus the HCG trigger group in PG 3/4 PRs. The number of retrieved oocytes and MII oocytes and the number of patients with good quality embryos were comparable between groups and live birth rates (LBR) per embryo transfer (ET) were significantly higher in the HCG group versus the dual trigger group in PG3/4 PRs (39.2% versus 19.2%; p = 0.026). NR dual trigger and HCG trigger groups were comparable in terms of patient age and LBR per ET did not significantly differ between these groups. The number of patients with good quality embryos was significantly higher in the dual trigger group versus the HCG group in NRsConclusion: Dual trigger does not seem to add additional benefits in terms of live birth rates in PG3/4 PRs and NRs. Nonetheless, considering the age difference and lack of homogenity in the number and day of embryos transferred in PG 3/4 PRs, major conclusion that can be drawn from the study is that dual trigger is not sys-tematically useful even in poor responders since the number of mature oocytes is comparable between groups. Larger scale studies are required for additional potential implications.
