What tests should I have for andropause?

To test for andropause, or low testosterone, a man should get a total testosterone level, which should include the serum-free testosterone and protein-bound testosterone. Generally normal values are between 300-800. If your testosterone level is low, then further work up may be indicated to identify if the problem is in the Leydig cells that produce testosterone, or the cells in your brain that produce hormones to activate the Leydig cells.

Physicians will administer a physical to determine if you have symptoms indicative of andropause. Blood tests determine hormonal levels, but they need to be done right and do demand expertise in interpretation, as well as a good lab.
