How Does the Body Make Testosterone?
Testosterone is a hormone made in both males and females, although it is found in significantly higher quantities in men. Because it is responsible for sexual development and sperm production in men, it is known as a male sex hormone. Testosterone is made in the highest quantities in the male testes through a series of reactions involving a number of specialized enzymes, and there are two different synthesis pathways that produce this hormone. Understanding these is important for the treatment of conditions such as infertility in men.
