Protocol summary

Study aim
evaluation of dual triggering for final oocyte maturation with a single dose of GnRH-a and a standard dose of hCG in GnRH-antagonist IVF/ Intracytoplasmic sperm injection (ICSI) cycles in normal responders.
Design
The study was a phase 2 trial. Randomization was performed based on a table of computer random numbers.
Settings and conduct
The study was conducted at Yazd Infertility Research Center.The study was one-sided blind .
Participants/Inclusion and exclusion criteria
The inclusion criteria were 18< Body mass index <30 kg/m2, and age ≤42 yr with the history of infertility for at least 1 yr that were candidate for ART protocol. Our exclusion criteria were the presence of endocrine disorders such as diabetes mellitus, hyperprolactinemia, thyroid disorders, congenital adrenal hyperplasia, Cushing syndrome, polycystic ovary syndrome, congenital uterine anomaliesdisorders, repeated implantation failure, day-3 FSH concentration ≥10 IU/L or serum anti-Mullerian hormone ≤1.0 ng/mL, and azoospermia.
Intervention groups
patients began ovarian stimulation with a flexible starting dosage of recombinant FSH ranging from 150 to 225 IU on the second day of the menstrual cycle for 5 consecutive days. Once the leading follicle had reached a size of 13 mm, co-treatment with the GnRH antagonist 0.25 mg/day, was initiated. When at least two leading follicles had reached 17 mm in diameter, final oocyte maturation was triggered by either 6500 I.U. hCG alone, or by 6500 IU hCG plus 0.2 mg of triptorelin (Decapeptyl; Ferring GmbH).Oocyte retrievals were performed under transvaginal ultrasound guidance 34 to 36 hours after triggering.
Main outcome variables
The primary outcome measure was clinical pregnancy rate and the secondary outcome measures were implantation rate,chemical pregnancy , ongoing pregnancy ,OHSS rate and abortion rate.

Abstract of published paper
Abstract Background: Gonadotropin-releasing hormone agonists (GnRH-a) was increasingly used for triggering oocyte maturationfor the prevention of ovarian hyperstimulation syndrome. Studies suggest that GnRH-a might be used as a better trigger agent since it causes both Luteinizing hormone and follicle stimulating hormone release from a physiologic natural cycle. Objective: The aim of this study was to evaluate the effect of dual-triggering in assisted reproductive technology outcomes. Materials and Methods: 192 normal responder women aged ≤42 years and 18< Body Mass Index <30 kg/m2 enrolled in this single-blind randomized controlled trial. All participants received antagonist protocol. For final triggering, women randomly were divided into two groups. Group, I was triggered by 6500 IU human chorionic gonadotropin (hCG) alone, and group II by 6500 IU hCG plus 0.2 mg of triptorelin. The implantation, chemical, clinical and ongoing pregnancy, and abortion rates were measured. Results: The mean of retrieved oocytes and obtained embryos were statistically higher in the dual-trigger group (group I), but the implantation and pregnancy rates were similar in two groups. Conclusion: The results of our study did not confirm the favorable effect of dual-triggered oocyte maturation with a GnRH-a and a standard dosage of hCG as an effective strategy to optimize pregnancy outcome for normal responders in GnRH-antagonist cycles. We think that this new concept requires more studies before becoming a universal controlled ovarian hyperstimulation protocol in in vitro fertilization practice.
