What is testosterone?

Testosterone is a sex hormone often associated with males, though the female body contains the testosterone in small quantities.  Testosterone controls sex drive for men, sperm production, muscle mass and bone mineral density, red blood cell production, and even affects his mood.  If a male has a low level of testosterone, the symptoms can include erectile dysfunction, and reduced bone mass and sex drive, among other effects. The production of testosterone is controlled by the brain and pituitary gland.

Normal level of testosterone

The normal range in the male body is around 270 to 1070 ng/dL with an average level of 679 ng/dL.  The testosterone level is the highest in adult males around the age of 20, when it is 700 ng/dl on an average. Testosterone levels above or below the normal range are considered to be imbalanced. According to a scientific report by Mayo Clinic the widely accepted normal level of testosterone in men ranges between 400 – 600 ng/dL.
