Testosterone is a steroid hormone that has been widely abused to enhance athletic performance because it is an anabolic steroid that stimulates growth. Testosterone is an androgen that controls virulization (masculinity). It is derived from another androgen, androstenedione, and is a chemical precurson to the estrogen steroid estradiol. Testosterone is mainly secreted from the testes, but some is also produced in the adrenal glands, so it is present in females as well as in males, but at much lower concentrations. Testosterone acts at specific nuclear receptors expressed in many tissues of the body, including the pituitary gland, and at some sites in the brain where it exerts effects on behaviour and regulates secretion of some hormones. In the brain, testosterone can also be metabolised (by the enzyme aromatase)to produce oestrogen. Testosterone has a negative feedback effect on the secretion of luteinising hormone and follicle stimulating hormone, which in men promote testis growth and sperm production. Accordingly, excessive levels of testosterone, while they result in muscle enhancement and increased aggression, can also result in hypogonadism (reduction in testis size) and infertility.
Its chemical IUPAC name is 8R,9S,10R,13S,14S,17S)-17-hydroxy-10,13-dimethyl-1,2,6,7,8,9,11,12,14,15, 16,17-dodecahydrocyclopenta[a]phenanthren-3-one and its molecular formula is C19H28O2.
Testosterone 5-alpha-reductase converts it to dehydrotestosterone.
Drug toxicity
Testosterone administration may cause myocardial infarctions.[1][2]
