Testosterone deficiency refers to low levels of testosterone in the blood. In men, it occurs when the testicles fail to produce testosterone, either because the testicles are dysfunctional, or because of a dysfunction of the pituitary gland, the area of the brain that sends signals to the testicles to stimulate testosterone production.
