Are there any differences between antagonist administration on days & lt;6 and ≥6 of Controlled Ovarian Hyperstimulation on assisted reproductive technique outcomes?

Conclusion Our results have demonstrated that there was no effect of antagonist administration on days <6 and ≥6 of COH on ART outcomes. However, taking cost-effectiveness into consideration, we suggest an antagonist administration on days <6 of COH since the necessary gonadotropin dose is lower.
