What is Testosterone?

Testosterone is a steroid hormone that is produced in both men and women, though men produce more of it.

It is primarily produced by the testicles in men and the ovaries in women.

It is responsible for men’s characteristics such as facial hair, a deep voice, growth of the testes and penis, and development of muscle mass.

Also,it is responsible for developing male genitalia, sexual drive, ability to produce sperm.

How does the body produce testosterone?

In men, aside from the testicles, testosterone is also produced in small amounts in the adrenal glands, located on the top of the kidneys.

The production of testosterone in the body begins during fetal development and continues through adolescence and adulthood.

The process by which body produce testosterone is quite complex, but I’ll break it down for you in simple steps.

Cholesterol is the building block of testosterone.

  1. The hypothalamus(testosterone manager) and pituitary gland(messenger that takes orders from the hypothalamus) control testosterone production.

    When brain detects requirement of testosterone, it produces a hormone called gonadotropin-releasing hormone. This hormone travels to a location in body known as the pituitary gland.

    The pituitary gland is also located in the brain, but in the back of the head. It is responsible for producing a hormone known as luteinizing hormone (LH).
  2. When brain’s pituitary gland detects gonadotropin-releasing hormone, it produces two hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH) (LH). Both of which travel through bloodstream to testicles.
  3. When the FSH and LH hormones reach testicles, FSH instructs the testicles to produce sperm, while LH instructs the Leydig cells to produce more testosterone. Leydig cells are found inside the testicles and are responsible for the production of androgen and testosterone.
  4. It is now up to the Leydig cells to produce testosterone.
  5. Leydig cells take cholesterol that is flowing around the blood and turn it into testosterone. 
    In case if there is not enough cholesterol in the body, then some of the required cholesterol is produced by the testicle itself so that the Leydig cells can convert it to testosterone.
  6. Once testosterone is produced, it’s then released into the bloodstream.
  7. When the hypothalamus detects enough testosterone in blood, it signals the pituitary gland to stop producing LH, causing testicles to produce less testosterone. That’s all

Isn’t that was pretty simple?
