Prostate cancer is another concern, as testosterone can fuel its growth. For example, low-t can speed bone loss, so your doctor may recommend a bone density test to see whether you also need treatment for osteoporosis. For instance, being overweight, having diabetes or thyroid problems, and taking certain medications, such as glucocorticoids and other steroids, can affect levels. But if you do not have any key symptoms, especially fatigue and sexual dysfunction, which are the most common, it is not recommended you go on the therapy given the uncertainty about long-term safety. A man's general health also affects his testosterone levels. The advice is that TRT should only be prescribed to treat sexual dysfunction in men with age-related decline in hormone levels. The guidelines don’t address screening or diagnosis of low testosterone levels (hypogonadism), or monitoring of those levels. Today, the American College of Physicians (ACP) released new clinical practice guidelines that advise doctors to prescribe testosterone only to treat sexual dysfunction in men experiencing age-related low testosterone. For congenital hypogonadism, testosterone replacement therapy often helps prevent problems linked to delayed puberty. If you have signs and symptoms of low testosterone, a healthcare provider will give you a physical exam. What are the side effects of testosterone replacement therapy? Is testosterone replacement therapy safe? While general awareness and understanding of testosterone replacement therapy has improved in recent years, many people still have questions. It is possible to have low levels and not experience symptoms. If your doctor diagnoses low testosterone, other tests may be considered before therapy. On the other hand, urologists are surgical specialists for the urinary tract and male reproductive organs. You should see an endocrinologist for low testosterone. Most males with symptoms of low testosterone don’t have a problem with their pituitary glands or testicles. Primary hypogonadism happens when your testicles aren’t making normal levels of testosterone. Providers call it male hypogonadism when you have symptoms along with these low levels. Low testosterone (male hypogonadism) is a condition in which your testicles don’t produce enough testosterone. The decrease in serum testosterone levels will lead to, among other effects, a reduction in sexual function and mood, as well as decreased bone mineral density and changes in body composition. Therefore, free and bioavailable testosterone levels will decrease with age more significantly than total testosterone levels.
