Abstract
The gross anatomy of the male genital organs of the healthy adult rabbit and its vascularization were investigated using thirty five male specimens. The morphological study was carried on six male rabbits and showed that the male genital organs constituted of testes, epididymis, ductus deferens, penis, prepuce and the accessory genital glands. The latter were found to be divided into; the ampulla of ductus deferens, the vesicular gland, the prostate gland and the bulbo-urethral gland. These regions were defined through shape and relation to adjacent organs. The vascularization of the male genital organs in rabbit was applied on twenty nine adult ones. The arterial supply was oriented by testicular artery from the abdominal aorta while the urogenital artery or the prostatic artery and the penile artery from internal pudendal artery. The arterial supply of the ductus deferens and its ampulla, the ventral branch and the caudal branch of vesicular gland from the umbilical artery. The venous drainage was achieved by the right testicular vein which drained directly into the caudal vena cava and the left one which was not consistent. Our work used also two drugs; Levitra® (Vardenafil) and Cardura® (Doxazosin) through oral administration. We observed that Levitra® was more efficient than Cardura® in reversing the time factor of duration and the action of the drug and the effect on wall of the blood vessels.
