Term Description

The testosterone/cortisol ratio (T/C ratio) is an indicator of recovery from exercise or over-training, and there is some suggestion in the literature of an association between an elevated T/C ratio and aggressive behavior. Testosterone is released following a series of a hormonal processes that begin in the pituitary gland, and its effects include increasing muscle protein synthesis and reducing the catabolic effects of cortisol. Cortisol is released by the adrenal gland under conditions of high physical and mental stress and high temperature, and its effects include reducing growth hormone and testosterone output, reducing muscle and increasing abdominal fat, and impairing immunity, learning and memory.

Part Descriptions

LP14045-6   Testosterone
Testosterone is an androgenic steroid and is the primary male sex hormone. Approximately half of circulating testosterone is tightly bound to a protein called sex hormone binding globulin (SHBG) and is biologically inactive. Another fraction is weakly bound to other proteins, such as albumin, and the remainder is unbound, or "free". Weakly bound and free testosterone together represent bioavailable testosterone. Both total and free testosterone levels decrease with age. Low testosterone is associated with many other conditions, including osteoporosis, Alzheimer's disease, obesity, diabetes and ischemic heart disease.

LP14045-6   Testosterone
A potent androgenic steroid and major product secreted by the Leydig cells of the testis. Its production is stimulated by luteinizing hormone from the pituitary gland. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to dihydrotestosterone or estradiol.
