About this study
Official title: Study on the Effect of GnRH Antagonist on hCG Day on Outcomes of Controlled Ovarian Hyperstimulation With GnRH Antagonist Flexible Multiple-dose Protocols
Gonadotropin-releasing hormone (GnRH) antagonists have been widely used for the prevention of premature luteinizing hormone (LH) surges during controlled ovarian hyperstimulation (COH) for in vitro fertilization and embryo transfer (IVF-ET) since the late 1990's.
Many years have passed since GnRH antagonists were introduced to prevent premature LH surges during stimulated cycles. However, there is still no consensus on the optimal GnRH antagonist protocol. Attempts at modifying GnRH antagonist protocols have been made to improve COH outcomes. However, a meta-analysis of 27 randomized controlled trials, including recent reports, showed significantly lower clinical ongoing pregnancy rates in the antagonist group. Thus, additional efforts are needed to identify the optimal stimulation protocols to achieve better follicular and embryonic development and to improve the pregnancy rates in COH using GnRH antagonist.
Given the assumption of a detrimental effect of GnRH antagonist on the pregnancy rate, with current protocols, we hypothesized that a shorter duration of GnRH antagonist administration might improve outcome.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
cetrorelix acetateDrug
The GnRH antagonist, cetrorelix acetate (Cetrotide; Serono) 0.25 mg was added daily, starting when the leading follicle reached 14 mm in diameter during ovarian stimulation for IVF. When the leading follicle reached a mean diameter of 18 mm or two follicles or more reached a diameter of 17 mm, 250 μg of recombinant hCG (Ovidrel; Serono) SQ was injected. In Group A, the GnRH antagonist continued to be used until the day of hCG administration. In Group B, the GnRH antagonist was not administrated on the hCG day
| Study group | Role | What they receive |
|---|---|---|
| A | Active comparator | Stimulated as conventional protocol Receives: Drug: cetrorelix acetate |
| B | Experimental | GnRH antagonist stopped one day earlier than conventional protocol Receives: Drug: cetrorelix acetate |
What is being measured
The primary outcome is the main question the study is designed to answer.
Maturity of oocytes, fertilization rate, embryo quality
Measured: 3 days
