Male Anatomy

November 9, 2015By

Anatomy of the male reproductive systemWhile female reproductive organs are located entirely inside the pelvis, male reproductive organs are located both outside and inside the pelvis. The male reproductive organs include:

Two testicles, (also known as testes) which produce and store sperm (the male reproductive cell), and produce the hormone, testosterone

The duct system, which is made up of the epididymis and the vas deferens and aid in transporting the sperm-containing fluid, called semen

The accessory glands, which include the seminal vesicles and prostate gland, and produce elements of semen

The penis, which has a fold of skin at the end, called foreskin. A procedure to remove it is called circumcision.

When boys reach sexual maturity, the two testicles, produce and store millions of tiny sperm cells. The testicles also produce the hormone testosterone, which is what causes boys to develop deeper voices, bigger muscles, body and facial hair. It also stimulates the production of sperm.

Although a baby boy is born with all the parts of his reproductive system, it isn’t until puberty – usually between the ages of 9 and 15 – ¬†that he is able to reproduce. The¬†pituitary gland in the brain sends messages to the testicles to produce testosterone, and consequently starts many physical changes. The timing of these changes is different for every boy, but the stages generally include the following:

  • the scrotum and testes grow larger
  • the penis becomes longer and the seminal vesicles and prostrate gland grow
  • hair begins to grow in the pubic area and later on the face and underarms. The boys voice may also deepen.
  • Boys have a growth spurt during puberty as they reach their adult height and weight.
