Objective To study the function of human chorionie gonadotrophin(HCG) in adjus-ting the vascular endothelial growth factor(VEGF) in rabbit phallus with hypospadias. Methods Rabbit hypospadias mode was made by Finasteride. After the spontaneous delivery, 35 rabbits were divided into 5 groups with 7 in each group. Four groups accepted HCG intramuscular injection for 7 consecutive days with dosages of 100,200,400 and 600 U, respectively. The control group accepted the same dosage of saline injection. Another 7 normal rabbits were used as normal controls without in-tervention. After 3 weeks, the rabbit phallus tissue was collected and the VEGF levels were detected by ELISA. Results Rabbits with hypospadias accepted HCG 100, 200, 400, 600 U injection had the phallus tissue VEGF level of 5.00±2.37,5.63±1.73, 10.35±2.34 and 16.91±2.34 pg/ml, respectively. While the rabbits accepted saline injection had VEGF levels of 3.99±1.19 pg/ml. The normal rabbit phallus tissue contained VEGF level of 14.82±3.32 pg/ml. There were significant differences between normal group and the rabbits accepted HCG 100, 200, 400 U injection (P＜ 0.05), but there was no difference with the rabbits accepted HCG 600 U injection (P＞0.05). The VEGF level in rabbits accepted 400 U HCG injection had significant difference with rabbits accepted 100, 200, 600 U HCG (P＜0.05). The VEGF levels in rabbits accepted 100, 200 U HCG injection had no difference with rabbits accepted saline injection(P＞0.05). Conclusions The VEGF in rabbit phallus with hypospadias is decreased. HCG of certain dosage could increase VEGF level in rabbit phallus with hypospadias.
