While low testosterone treatment is prescribed to combat the effects of aging such as diminished libido, lowered muscle strength and bone density, erectile dysfunction and depression, it has now been proven by medical studies that testosterone products can have adverse health effects, ranging from minor to more serious, life-threatening ones. Serious side-effects include:
This is the most common type of side effects that has been seen in patients who undertook low testosterone therapy. Patients with a history of heart disease and complications were more likely to have a heart attack.
The second most common type of side effects. This happens because of a disturbance in the blood supply to the brain. Mini-strokes (transient ischemic attack or TIA) are also possible and have been alleged at least in one lawsuit against the makers of AndroGel
While the research is not as conclusive as it is on heart strokes and heart attacks, the risk for prostate cancer has not been entirely ruled out. Those who have undergone or are currently undergoing testosterone therapy are advised to take a PSA test once or twice a year.
