Testosterone is the primary male sex hormone and androgen in males. [3] In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
Androgens that bind to and activate the androgen receptor have numerous physiological functions which can broadly divided into androgenic (male sexual development) and anabolic (building muscle and bone). The anabolic effects are important in both males and females, although females have lower circulating levels of androgens.
The elimination of testosterone in adulthood has been shown to reduce sexual motivation in both male humans and male primates. [1] Male humans who had their testicular function suppressed with a GnRH antagonist displayed decreases in sexual desire and masturbation two weeks following the procedure. [2]
The following is a list of hormones found in Homo sapiens.Spelling is not uniform for many hormones. For example, current North American and international usage uses [citation needed] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier spelling gonadotrophin.
The androgen receptor (AR), also known as NR3C4 (nuclear receptor subfamily 3, group C, member 4), is a type of nuclear receptor [9] that is activated by binding any of the androgenic hormones, including testosterone and dihydrotestosterone, [10] in the cytoplasm and then translocating into the nucleus.

A small 2024 study published in Endocrine Abstracts showed that semaglutide was more effective than testosterone replacement therapy in improving body composition and increasing testosterone for ...
Testosterone has a ketone group on the 3 carbon and a hydroxyl on the 17b carbon. A steroid with modifications away from testosterone in one or both of these areas is commonly referred to as a "prohormone". These enzymatic changes occur with the body's bidirectional enzymes. [3] [4]
