Testosterone is a steroid hormone that is secreted by the testes, as well as by the adrenal glands. It is responsible for the development and maintenance of secondary sexual characteristics in men and women. Testosterone levels are reduced in patients with squamous cell carcinoma, which may be due to a deficiency of this hormone. Testosterone has been shown to increase levels of natriuretic peptides (NPs), which are important for regulating blood pressure and fluid balance. A deficiency of testosterone has also been linked to bowel disease, such as ulcerative colitis or Crohn's disease. In addition, testosterone may be used as a model system for studying other steroids because it has been found to bind to specific proteins on the surface of human cells, called CDNA clones.
