Anabolic steroid side effects national geographic

Steroid isolation , depending on context, is the isolation of chemical matter required for chemical structure elucidation, derivitzation or degradation chemistry, biological testing, and other research needs (generally milligrams to grams, but often more [42] or the isolation of "analytical quantities" of the substance of interest (where the focus is on identifying and quantifying the substance (for example, in biological tissue or fluid). The amount isolated depends on the analytical method, but is generally less than one microgram. [43] [ page needed ] The methods of isolation to achieve the two scales of product are distinct, but include extraction , precipitation, adsorption , chromatography , and crystallization . In both cases, the isolated substance is purified to chemical homogeneity; combined separation and analytical methods, such as LC-MS , are chosen to be "orthogonal"—achieving their separations based on distinct modes of interaction between substance and isolating matrix—to detect a single species in the pure sample. Structure determination refers to the methods to determine the chemical structure of an isolated pure steroid, using an evolving array of chemical and physical methods which have included NMR and small-molecule crystallography . [4] : 10–19 Methods of analysis overlap both of the above areas, emphasizing analytical methods to determining if a steroid is present in a mixture and determining its quantity. [43]

Abuse of anabolic steroids, however, can result in significant harm to the body. In humans, abuse can lead to coronary heart disease , sexual and reproductive disorders, immunodeficiencies , liver damage, stunted growth, aggressive behaviour , susceptibility to connective tissue injury, and (in females) irreversible masculinization. Similar side effects can occur in livestock and other animals. In horses , for example, anabolic steroids can cause liver damage and weakening of the tendons and can result in decreased testis size and sperm production in stallions and altered reproductive cycling in mares. Anabolic steroids are readily detected in urine and blood .
