What is Testosterone? Testosterone is the male sex hormone produced in testicles (Leydig cells) and a smaller amount in ovaries. Yes, ladies also produce testosterone.
It is synthesized from cholesterol and converted in the liver to inactive metabolites. Testosterone is binding to androgen receptors which represent the mechanism of action of testosterone.
An average male produces 20 times more testosterone than female on a daily basis. Also, ladies are more sensitive to its effects. The production of testosterone increases during puberty, and begins to decrease during 30s.
Not only that it’s a sex hormone, but it is also an anabolic steroid as well. Testosterone is an illicit substance used by athletes to enhance their performance. However, it is also a medication mostly prescribed for low testosterone and breast cancer treatment.
Testosterone has many effects on our body, even before we are born. It affects the formation of genitals and even has an impact on our sex-typical behavior during our adult years, for both boys and girls.
After birth, testosterone has an essential role in creating primary and secondary sexual characteristics.
Primary sexual characteristic includes the formation of genitals and male urinary tract including urethra and prostate. Secondary sexual characteristics are bone mass, fat distribution, muscle mass, body hair, deeper voice, libido, and height.
Testosterone is also responsible for sperm production. Therefore, plays an important role in fertility and the production of red blood cells.
Testosterone levels usually drop with age. However, lack of the male sex hormone can be caused by some medical conditions or genetic disorders.
