Did you mean Testosterone?

GlossaryTestosterone

hormone that regulates male traits and reproductive functions

Testosterone is a hormone primarily produced in the testes in men and in smaller amounts in the ovaries and adrenal glands in women. It plays a crucial role in the development of male reproductive tissues, the promotion of secondary sexual characteristics like increased muscle and bone mass, and the growth of body hair. Additionally, testosterone influences mood, energy levels, and overall well-being.
