Testosterone is a hormone produced by the body. In men, testosterone is mostly produced in the testicles, stimulating the production of sperm and increasing sex drive. It is also responsible in muscle and bone build-up. As men grow old, the production of testosterone decreases and Andropause takes place – the male counterpart of menopause.
Testosterone level is relatively linked with man’s sex drive. Though testosterone alone does not cause an erection, Nitric oxide, a molecule that triggers an erection, is produced as a result of the simulation of receptors in the brain.
Low testosterone is also linked to many conditions that cause erectile dysfunction, including obesity, diabetes, and atherosclerosis. The level of testosterone in the body also indicates other body functions such as the production of hair. Men with low testosterone usually have an evident decrease in energy levels, thus, extreme fatigue is experienced. Aside from those, other common physical setbacks for having low testosterone level are loss of muscle mass, increase in body fat, decrease in bone mass, and mood changes.
Low testosterone may lead to other complications and it is best to have early detection so that preventive measures can be done. With the growing number of available remedies in the market, the most common testosterone replacement therapies are patch or gel, injections, or pellets.
