In men’s testes, some female ovaries and both sexes’ adrenal glands, the natural production of the steroid hormone testosterone occurs. This hormone connects to the muscle tissue’s androgen receptors so as to grow muscle via the increase of protein synthesis in the cells of such muscles. In the puberty stage of males, testosterone leads to masculine characteristics which include increase of hair on the face and body and voice deepening.
One of the medical conditions that may cause low testosterone is diabetes according to studies as many diabetic men are found to have a high chance of having testosterone deficiency. There are also men having low testosterone who can develop diabetes. It is this steroid hormone that assists the tissues of the body to absorb more blood sugar to respond to insulin. Males with testosterone deficiency are often resistant to insulin thus they have to produce more of this hormone to normalize their blood sugar.
