Testosterone replacement therapy is the most common method to treat low testosterone. Testosterone can be given as an injection, as a gel, as a pellet implanted in the office, or as a patch. Future blood tests are also usually necessary prior to initiating therapy as well as for those patients already being treated.
The benefits of testosterone treatment may include improvements in energy, libido, erection quality, better memory and increased muscle mass.
Patients who have cancer of the prostate, or are suspected to have cancer of the prostate should not use testosterone replacement. Testosterone replacement may cause elevated red blood cell counts, impairment of fertility, liver dysfunction or exacerbation of heart failure.
