Testosterone, commonly known as test, is an endogenous steroid hormone mainly synthesized by the male testes and female ovaries, along with minor contributions from the adrenal cortex. Serving as the primary androgenic and anabolic hormone, it performs essential physiological functions in both sexes.

Testosterone exerts a substantial influence on overall wellness, modulating libido, physical strength, immune activity, and bone density maintenance to reduce osteoporosis risks. Quantitative data indicates that adult males produce roughly 20-fold the amount of testosterone generated by females, resulting in circulating physiological concentrations 7 to 8 times greater in men.
