Testosterone is a sex hormone produced in the male testes and the adrenal glands of both males and females, and it contributes to a large number of bodily functions.
As both men and women produce this hormone, its roles extend beyond the conventional sexual-related functions such as sperm production and libido to tissue growth and brain function.
Testosterone is a steroid hormone derived from the fatty substance cholesterol, which is produced in both men and women, although men produce 10 times more. It has a number of roles in the body, and these can be broadly placed into two categories, those relating to sexual development and those related to anabolism, or tissue growth. Other functions which do not fall into these categories include brain functions related to neuron growth, cognitive ability and mood.
