PURPOSE: This study aimed to compare the efficacy of human chorionic gonadotropin (hCG) and dual-trigger (gonadotropin-releasing hormone agonist [GnRH-a] and hCG) protocols in terms of cumulative live birth rate (CLBR) and other pregnancy o…
OBJECTIVE: This retrospective study aimed to explore whether puncturing and aspirating asynchronized large follicles during long GnRH-a protocol COH impacted IVF-ET outcomes. METHODS: A total of 180 patients with asynchronized follicles du…
BACKGROUND: Previous studies have shown that frozen embryo transfer (FET) resulted in increased live birth rates (LBR) and reduced the risk of ovarian hyperstimulation syndrome (OHSS) than did fresh embryo transfer in women with polycystic …

BACKGROUND: Gonadotropin-releasing hormone antagonist(GnRH-ant) has been shown to have a negative effect on endometrial receptivity. Therefore, the use of lower doses of GnRH-ant during controlled ovarian stimulation (COS) may improve endom…
Background: Dysregulated migration and invasion of endometrial stromal cells is implicated in the pathogenesis of endometriosis. Hypoxia functions as critical microenvironmental factor that results in promotion of endometrial stromal cells …
Obesity exerts negative effects on the metabolic homeostasis of cells in various tissues, but how it influences ovum metabolism is not fully understood. Previous studies demonstrate that oocyte genes that regulate oxidative stress, lipid me…
