In the male reproductive system, some organs are located outside the body and others are inside the body.

The penis and the scrotum are the external parts of the male reproductive system. Internal male organs involved with reproduction include the testes, epididymis, ductus (vas) deferens, seminal vesicles, ejaculatory ducts, prostrate gland, bulbourethral (Cowper’s) glands, and urethra.
