The current study aimed to investigate the effects of luteal gonadotropin-releasing hormone
(GnRH) antagonist pretreatment on the outcomes of diminished ovarian reserve (DOR) …

This meta-analysis aimed to compare the outcomes of the gonadotrophin-releasing
hormone (GnRH) antagonist/letrozole protocol with those of the conventional GnRH …

Studies have shown that letrozole cotreatment can improve clinical outcomes in high and
poor responders in GnRH-antagonist protocol. However, whether letrozole is also beneficial …

Objective There is a lack of consensus regarding the ideal management of patients with
poor response to ovarian stimulation. Letrozole (Lz) increases endogenous gonadotropin …

Background and Aims: A panel of experts (the Poseidon Group) introduced a new and more
detailed stratification for poor ovarian responders in order to predict the prognosis of IVF …

Background: Gonadotropin-releasing hormone (GnRH) antagonist protocol has been
proposed as a potentially proper option for the patients with limited ovarian reserve …

Objective To evaluate the effectiveness of gonadotropin-releasing hormone (GnRH)
antagonist in poor ovarian responders undergoing in vitro fertilization (IVF). Design …

OBJECTIVE: To compare reproductive outcomes in normoresponding IVF patients
undergoing ovarian stimulation with the GnRH antagonist protocol vs. GnRH agonist …

Objective To evaluate the effectiveness and safety of GnRH antagonist and GnRH agonist in
supposed normal ovarian responders undergoing IVF. Methods Data from 6 databases were …

Objective To evaluate the effectiveness and safety of gonadotropin-releasing hormone
antagonist (GnRH-ant) protocol and gonadotropin-releasing hormone agonist (GnRH-a) …
