INTERNAL GENITAL ORGANS

• Internal genital organs should be evaluated by rectal palpation.

Complete examination of accessory sex glands (ampulla, seminal vesicles, prostate and cowper's gland) and urethra for diseases and abnormalities is carried out by rectal palpation.

• For orientation, the pelvic portion of the urethra should be located.
• It lies on the floor of the pelvis and feels like a cylinder, 3-4 cm in diameter. It is firm and slightly flattened on top.
• The body of the prostate is located on the anterior-dorsal end of the pelvic urethra at about wrist depth.
• It forms a transverse ridge that is easy to locate and palpate which serves as a landmark for location of the ampullae and vesicular glands.
• They empty into the pelvic urethra at the colliculus seminalis, which is located just beneath the body of the prostate in the pelvic urethra.
• The ampullae and vesicular glands can be stroked several times to prime them for effective electro ejaculation at the time of palpation.
