anatomy of the male reproductive organ

1. Male Internal Genital Organs

2. Ductus Deferens

9. •AA: artery to ductus deferens
-- from superior or inferior vesical aa
-- anastomoses with testicular arteries
•VV: mostly by testicular vein
-- terminal part via vesical or prostatic plexus
•LN: to external iliac lymph nodes
•NN: plexus around duct,
-- formed by vesical or testicular plexuses
