Testosterone is a principal male sex hormone Though this hormone normally (and necessarily) occurs in small amounts in females, it is chiefly known as the hormone responsible for stimulating the development of male sex organs and male secondary sexual characteristics, e g facial hair, deepening of the voice, and muscle development
a potent androgenic hormone produced chiefly by the testes; responsible for the development of male secondary sex characteristics
A steroidal hormone secreted by interstitial cells (cells of Leydig) located within the testes It promotes the development of male secondary sex characteristics and the development of spermatozoa
-a hormone made by the testicles and adrenal glands, and also in various cells of the body, that promotes masculine traits
The hormone found in humans, mostly in males, that can lead to aggressive behavior
The hormone responsible for development of male sexual characteristics, which includes major growth in the larynx
The naturally occurring male hormone When administered as a drug it can cause gain in lean body mass, increased sex drive and possibly aggressive behavior Many men with HIV have low testosterone levels
Testosterone is a hormone found in men and male animals, which can also be produced artificially. It is thought to be responsible for the male sexual instinct and other male characteristics. the hormone (=chemical produced by the body) in males that gives them their male qualities (testis + sterol ( STEROID) + -one). Masculinizing sex hormone produced by the testes. It is responsible for the development of the male sex organs and secondary sex characteristics (e.g., facial hair, masculine musculature, deep voice, and male-pattern baldness). Testosterone can be manufactured by modifying other, less expensive steroids. It is used in the treatment of hypogonadism, undescended testes (cryptorchism), and certain cancers
a steroid hormone produced by the testes and adrenal glands Testosterone is required for sperm production, the development of the male reproductive organs, and the emergence of male secondary sexual characteristics The hormone is also required for the buildup of lean muscle mass Testosterone levels are often low in HIV positive men; the hormone is under study as a therapy for wasting syndrome Possible side effects include acne, mood swings, change in sex drive, liver toxicity, prostate enlargement and masculinization in women
