There are many changes that the human body usually goes through over time. The male body, for instance, usually changes over time. The moment a man hits age 30 years, the body usually goes through a number of changes. For instance, body fat usually increases considerably while muscle mass and bone density usually reduces considerably. Men may also start experiencing balding, mood swings and a wide range of other changes. Some men may also experience low libido, erectile dysfunction and poor sexual stamina among other things.

To reverse these changes, men need to go for testosterone replacement therapy, which is offered at most medical facilities by qualified medical practitioners. After therapy, men expect to have healthy t-levels. As a result, all these unwanted changes will be reversed. This means that therapy can help older men to recover their lost youthful vigor.
