Erectile dysfunction commonly occurs with aging and chronic disease such as obesity and diabetes. Andropause (a decline in testosterone levels occurring in aging) can give rise to symptoms of testosterone deficiency such as fatigue, low mood and erectile dysfunction. Testosterone deficiency may also result from problems with the pituitary gland or with the testes.
Testosterone replacement can be helpful in men who are suffering from hypogonadism (a condition marked by low sex hormone). However testosterone treatment if administered indiscriminately can lead to a host of adverse effects. It is therefore important to consult a physician who is well versed with testosterone therapy, its adverse effects and means of monitoring the therapy, before embarking on such replacement. If administered appropriately, testosterone replacement therapy can be helpful in many of these patients who suffer from sex hormone deficiency.
