The penis has two main jobs: urination and reproduction/sexual function. It lets urine leave the body through the urethra, and during sexual arousal it fills with blood to become erect, which allows sexual intercourse and ejaculation.

Quick Scoop

  • Peeing: urine exits through the urethra, which runs through the penis.
  • Sexual function: it becomes erect when blood fills erectile tissue, helping with intercourse.
  • Ejaculation: semen leaves the body through the penis during orgasm.
