Types of Testosterone Therapy


There are four approved types of Testosterone therapy available: gels, patches, injections and sustained release pellets.  Oral Testosterone is not available in the United States.

Gel:  Applied daily


  • Androgel
  • Axiron
  • Fortesta
  • Testim

**With Testosterone gels, it is important to remember that after applying you may not shower, swim, sweat excessively or have skin-to-skin contact with your significant other for at least 4 hours.

Patch:  Applied daily

  • Androderm

--In about 25% of patients a mild skin reaction may occur at the site of the patch.  This is easily treated with hydrocortisone cream.

**Gels and patches are the more expensive forms of Testosterone therapy, but give even levels of testosterone.  Despite applying properly, about 20% of patients do not achieve adequate levels.


--instruction/education is given for patients to self- inject or have someone of choice give

--trough* lab levels are essential for accurate treatment

--typically this is the most affordable, however, it does involve frequent needle sticks


Side Effects of Testosterone

  • Stimulation of the bone marrow to produce too many red blood cells may occur (we call this erythrocytosis).  This is easily corrected by donating blood as directed.
  • Breast enlargement
  • Lowering of HDL (good cholesterol)
  • An increase in the size of the prostate gland, causing more frequent urination
  • Heightened aggressiveness
  • Testicular shrinkage
