Low testosterone or testosterone deficiency is when the body isn’t able to make enough testosterone to work normally. Because testosterone is the major androgen, it’s key not just for the physical changes that happen during puberty, like the development of the penis and testicles, and the growth of body hair, but for your bones and muscles, sex drive, and your general mood.
