What Causes Low Testosterone?
The causes of low testosterone are classified into two main categories: primary and secondary male hypogonadism.
Causes of Primary Male Hypogonadism
With primary male hypogonadism, it occurs due to either a congenital or an acquired testicular problem. Congenital means that you are born with it, and acquired means that it is a result of something else, such as trauma, radiation, or mumps.
Causes of Secondary Male Hypogonadism
Secondary male hypogonadism is responsible for most of the low testosterone cases. With this, testosterone levels are low due to complex physiological and behavioral factors that interfere with the production of testosterone. These factors can include obesity, head trauma, and diabetes.
