Expression of the vascular endothelial growth factor receptor system in porcine oviducts after induction of ovulation and superovulation

This study was performed to determine the influence of insemination as well as treatment with human chorionic gonadotropin (hCG) and equine chorionic gonadotropin (eCG) on expression of the vascular endothelial growth factor (VEGF) system in porcine oviducts. In the first experiment, 10 gilts were assigned to 2 groups: cyclic (treated with phosphate-buffered saline; n = 5) and inseminated (n = 5). In experiment II, 15 gilts were assigned to 3 groups: inseminated (control; n = 5), induced ovulation and/or inseminated (750 IU eCG, 500 IU hCG; n = 5), and superovulated and/or inseminated (1500 IU eCG, 1000 IU hCG; n = 5).
