What is it?
Testosterone is the primary sex hormone and an anabolic steroid in men. It plays a key role in the development of male reproductive tissues such as penis, testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body/facial hair, as well as being responsible for sperm production and sex drive.
In women, testosterone is produced in the ovaries and adrenal gland. It is one of several male sex hormones in females. Testosterone affects ovarian processes and bone strengh, and needs to be balanced with estrogen and other androgens, for the reproductive system to work normally.
