Healthy testosterone levels protect men’s health in a variety of ways, including shielding them from cardiovascular disease and prostate cancer. According to studies, correcting low testosterone in a patient with heart disease can improve diabetes and obesity, dilate the arteries, normalize blood pressure, and improve circulation. Although testosterone has historically been contraindicated for prostate cancer, new studies refute this belief, including a paper published in 2006 by Dr. Abraham Morgentaler, who found that “low levels of testosterone can be a risk factor for getting prostate cancer.” Dr. Morgantaler now believes that testosterone treatment provides more benefit than risk.
