Testosterone and Older Men – What Causes Side Effects?

A recent study published in the prestigious New England Journal of Medicine (NEJM) casts a shadow on the common use of testosterone therapy in older men for boosting their energy and vitality. An FDA-approved testosterone gel was shown to significantly increase risk for adverse cardiovascular, respiratory, and dermatological events in men 65 or older who had impaired mobility and increased health risks.

These unexpected negative results fly in the face of decades of good research on testosterone therapy in older men showing it to be beneficial to the cardiovascular system, and improve sexual function, mood, energy level, and muscle and bone mass and strength.
