Reduced production of the male sex hormone testosterone is a condition called male hypogonadism. The hormone is essential to normal male development during puberty and to the production of sperm. The condition can affect men from birth or appear later in life due to injury, infection, or other causes.
The effects and potential treatments for male hypogonadism will vary depending on the patient’s age and the underlying cause. Some cases of low testosterone can be treated using testosterone replacement therapy.
Primary male hypogonadism is the result of an issue with the testicles. This can result from numerous causes, including injury. Secondary male hypogonadism is the result of problems with the hypothalamus or pituitary gland. These play a crucial role in signaling the production of testosterone by the testicles. The two conditions are not mutually exclusive. Other factors can include inherited traits, injury, and infection.
