Testosterone is one of the hormones responsible for sex drive and sperm production in men. It also plays a role in the size and strength of your muscles and bones, where you store fat on your body, and is important for making red blood cells. In men, testosterone is mainly produced in the testes. Women also produce testosterone, but in much smaller amounts. Sometimes testosterone levels become too low, causing you to feel unwell and may need to be treated.
