Steroids

Testosterone was often referred to as the "male hormone", It is responsible for the development of the male characteristics such as lowering of the voice, hair growth, and because the male body produces much more of it than the female. However, it is responsible for stimulating quite a few other processes. Steroids are a very large class of compounds, which occur in all animalsalso. The steroids used by athletes are mostly androgenic steroids: steroids, which act like testosterone. These steroids are used to treat inflammatory disorders such as cortico steroids, which do not have anabolic effects.
Testosterone in the male is produced mainly in the testis, an a small amount is being produced in the adrenal. It is synthesized from cholesterol. The regulation of its production may be simplified which means the hypothalamus (part of the brain) produces gonadotrophin releasing hormone which acts on the anterior pituitary to increase the production of luteinizing hormone and follicle stimulating hormone. The luteinizing hormone acts on the Leydig cells in the testes, causing them to produce testosterone. The follicle-stimulating hormone with testosterone acts on the Sertoli cells in the testes to regulate the production and maturation of the spermatozoa. Testosterone in turn acts on the hypothalamus and anterior pituitary to suppress the production of gonadotrophin releasing hormone, follicle-stimulating hormone, and the luteinizing hormone producing a negative-feedback mechanism. This keeps everything well regulated. The small amount produced in the adrenal (in both sexes) is regulated by secretion of adrenal corticotrophin hormone, also secreted by the pituitary.
Testosterone, and its metabolites such as dihydrotestosterone, act in many parts of the body, producing the secondary sexual characteristics of then male: balding, facial and body hair, deep voice, greater muscle bulk, thicker skin, and genital maturity. At puberty it produces acne, the growth spurt and the enlargement of the penis and testes as well as causing the fusion of the epiphyses bringing growth in height to an end. It plays some role in maintaining the sexual organs in the adult, but only a low concentration is required for this.
The normal production of testosterone in the adult male is 4 to 9mg per day. The normal plasma concentration is 22.5nmol/l, of which 97% is pro...

...h blood pressure, other cardiovascular diseases, baldness, stunted growth in adolescents, and enlargement of pre existing prostate tumors can persist even after steroid use has stopped. Female steroid users, in addition to the problems listed above, can have virilizing (masculinizing) symptoms when using the harsher, androgenic compounds, including amenorrhea (which is reversible), clitoral hypertrophy, deeper voice, excessive growth of body hair, loss of scalp hair and alterations in skin texture (which frequently aren't reversible). Not all of these conditions are caused by all anabolic steroids. Some of the harsher anabolic steroids will only cause these problems for a certain percentage of the users, above certain dosages. Some of the milder anabolic steroids cause almost none of these side effects. There fore, it is a mistake to state that all steroid users will come down with these side effects. Any such silly statements will be readily flamed on m.f.w. Most of the side effects of steroid use result from the conversion of testosterone to estrogen or dihydrotestosterone. Some anabolic steroids do not undergo this conversion. These steroids will have fewer side effects.
