Male Internal Anatomy

  • Testicle: Once a boy reaches a certain point in puberty, it is in the testicles that millions of very small sperm cells are produced every day. Testicles also produce hormones like testosteron
  • Epididymis: The tube in which sperm mature and are stored. It is tightly coiled on top of and behind each testicle.
  • Vas Deferens: A long, narrow tube that carries sperm from each epididymis to the seminal vesicles.
  • Seminal Vesicles: The two seminal vesicles produce fluids in which sperm move and are nourished.
  • Prostate Gland: Produces additional fluid which nourishes the sperm.
  • Sperm: The male reproductive cell.  The sperm contains the male’s genetic information.
  • Semen: The combination of fluids and sperm which produces a sticky, milky white fluid.
  • Urethra: A narrow tube inside the penis that carries fluids (semen and urine) out of the body through a hole at the tip of the penis.
  • Bladder: Where urine is stored. It is not part of the reproductive system, but urine leaves the body through the urethra which is also how semen leaves the body. Urine and semen never leave a male’s body at the same time.
