To many men, testosterone therapy seems like the answer to a lot of prayers. The problem is, although there are many good benefits that come from testosterone, such as more energy and greater sex drive, there also seems to be a risk of heart related issues that can come after it is taken. Three years after a person has an angiogram, there appears to be an increased risk of heart attack or stroke in those that are on the therapy. Doctors are unclear as to why, therefore, proceed with caution.
