The Influence of Dopamine Agonist Cabergoline on Oocyte Maturation

The dopamine agonist cabergoline inhibits phosphorylation of the vascular endothelial growth factor receptor-2(VEGFR-2), which prevent vascular endothelial growth factor (VEGF) overexpression and reduce the severity of Ovarian hyperstimulation syndrome. However, VEGF plays an important role in the growth and maintenance of ovarian follicle and developing embryo by mediating angiogenesis.This study was designed to analyze whether the timing cabergoline administration on the day of human chorionic gonadotropin (hCG) injection or after oocytes retrieved affects the oocyte maturation and outcome of assisted reproduction treatment.
