Facts

  • Penis is an external male sexual organ, responsible for sexual pleasure, reproduction, urination and ejaculation.
  • The shaft of the penis is comprised of two chambers of spongy tissue, the corpora cavernosa, which run along the inside length of the penis.
  • You cannot exercise the muscles of the penis since the penis is not made of muscles, it is made of veins that through congestion and vasodilatation generate an erection.
