Exciting research from the University of Texas in San Antonio shows that a non-prescription drug called DHEA can help to treat impotence.

When a man goes to his doctor complaining of impotence, doctors order blood tests for diabetes and other causes of nerve damage; arteriosclerosis; the male hormone, testosterone; and prolactin, a chemical secreted by a brain tumor that causes impotence. Most of the time, impotence is caused by diabetes or arteriosclerosis, but sometimes, all tests are normal and doctors do not know the cause. In 1994, the Massachusetts Male Aging Study showed that impotent men often have low blood levels of a chemical produced by the adrenal glands, called DHEA that is converted to both the male hormone, testosterone, and the female hormone, estrogen.

In this placebo-controlled study, men who had low blood levels of DHEA (below 1.5 mu mol/L) and normal levels of the male hormone, testosterone; the prostrate-cancer screening test, PSA, and prolactin were given 50 mg DHEA pills one time a day for 6 months and had a marked improvement in their ability to have erections. There was no evidence of harmful effects on their hormone levels as blood levels of PSA, prolactin, testosterone and prostate size did not change. See report #M127 for more about impotence.
