Vas deferens
- The vas deferens transports sperm from the epididymis in anticipation of ejaculation.
- The vas deferens is the thin tube that starts from the epididymis to the urethra.
Testes or Testis
- The testes are the two - oval shaped male organs that produce sperm and hormone testosterone.
- The testes develop within the abdomen during fetal life.
- The testes hang away from the body in the scrotum.
(This is because sperm need to be kept a few degrees cooler than the body temperature.)
