Pituitary suppression before frozen embryo transfer is beneficial for patients suffering from idiopathic repeated implantation failure
In 21 patients with idiopathic repeated implantation failure, GnRHa suppression followed by hormone replacement therapy for frozen embryo transfer significantly improved pregnancy, implantation, and ongoing pregnancy rates compared to previous protocols.

The study evaluated whether long-term pituitary suppression with a GnRH agonist before frozen embryo transfer improves outcomes for women with idiopathic repeated implantation failure (RIF), using 21 patients given GnRHa plus hormone replacement therapy (G-HRT) and comparing their frozen/fresh cycle results with 56 prior cycles they had undergone under previous protocols. The key findings were that the G-HRT protocol was associated with substantially higher pregnancy outcomes, including pregnancy rate (70% vs 17%), clinical pregnancy rate (60% vs 11%), implantation rate (40% vs 6.3%), and ongoing pregnancy rate (38% vs 5%). The paper’s main limitation is that the comparison uses each patient’s prior cycles under different protocols rather than a concurrently randomized controlled design. This paper is centrally about endometriosis and/or adenomyosis — endometriosis/adenomyosis are highlighted as conditions in which long-term GnRH agonist–based endometrial preparation improved IVF/transfer outcomes, and this study extends that approach to idiopathic RIF patients.
