Clinical Notes

Testosterone is the hormone responsible for controlling fertility and the development of sperm in men. Testosterone also plays an important part in the development of male sex characteristics such as a deeper voice and certain patterns of muscle development and hair growth. In women or anyone with ovaries, testosterone impacts overall growth as well as development of muscle and reproductive tissue.
