The Ups and Downs of Testosterone Supplements

Testosterone and Male Menopause - Forbes.com:
"Testosterone supplements have been shown to have both positive and negative side effects. The positive benefits are that it makes a man's bones stronger and less prone to osteoporosis or bone fractures. Testosterone has also been shown to improve a man's cardiovascular health.

On the negative side, experts say they do not know the long-term consequences of testosterone replacement. One of the main concerns is the effect it may have on the prostate, because testosterone can enlarge it. Increased testosterone also can cause blood clots and liver dysfunction. Jacobs says another problem is that it can lead to hair loss, and in the rare circumstance the testosterone can be partially changed to estrogen, which causes breast growth.

In the meantime, experts say, it's best to see a doctor who can administer the proper amounts of testosterone. They also recommend that men do not try to supplement themselves, whether it is for treating low levels of testosterone or for activities such as weightlifting. Excessive amounts of testosterone can affect fertility, shrink testicles, cause manic anger and stunt growth."
