What is Testosterone?
Testosterone is a hormone produced in the testicles. It is a male sex hormone and an adequate level of testosterone is needed for normal male sexual development and function. Testosterone is also present in women but in smaller amounts. During puberty, testosterone plays a key role in male characteristic development. Testosterone has key functions such as the development of muscle and bone, sperm production, deepening of voice and hair growth.
What is Low Testosterone?
Low testosterone is defined as less than 300 nanograms of hormone per deciliter of blood by the American Urology Association. As men age, the level of testosterone declines over the years. This is normal, so older men generally have lower testosterone levels.
Some men suffer from low testosterone, a condition called Testosterone Deficiency Syndrome (TD) or Low Testosterone (Low-T). This means your body doesn't have sufficient levels of testosterone. Around 2 out of 100 men suffer from low testosterone. Around 50% of men over the age of 80 have TD. There is a higher prevalence of TD in men who suffer from diabetes or are overweight. A study shows that 30% of overweight men have TD while only 6.4% of men in the normal weight range suffer from TD. Another study showed 24.5% of diabetic men had TD compared to 12.6% of men without diabetes.
