Because prostate cancer growth is fueled by androgens- especially testosterone- androgen deprivation therapy (ADT) is the treatment of choice for the 40% of men with this cancer who have disease that has spread beyond the prostate. But ADT has been shown to have many deleterious effects on the body. These include osteoporosis, increase in body fat and a decline in muscle size and lean body mass. They also found that there was an increase risk of diabetes and greater arterial stiffness. But probably the more profound symptoms these men experienced were fatigue, moodiness, emotional lability, anxiety, and depression.
All of these symptoms I see in men that have gone through andropause naturally. Once their testosterone levels are brought up to optimal levels these myriad of symptoms disappear and the men feel like they have their life back again.
