Testosterone belongs to the class of medications called androgens (male hormones). This medication is used to replace testosterone in males who have conditions caused by low testosterone levels. It is also used to treat erectile dysfunction (erectile difficulties or the inability to attain or maintain an erection) and other male sexual problems when they are caused by low testosterone levels.
This medication works by replacing the testosterone that would normally be produced by the body. Testosterone should only be used if testosterone deficiency has been confirmed by symptoms and blood tests.
