Oddly enough, the verbal and spatial improvements. Testosterone levels are at their highest during adolescence and early adulthood. In general, due to the current lack of long-term safety studies on testosterone therapy, testosterone replacement therapy in older men should be used with caution. The male body needs to produce the right amount of testosterone to maintain optimal physical, sexual and mental health. Because of its diverse functions, low testosterone levels can cause a wide range of symptoms, such as erectile dysfunction, decreased libido, and decreased muscle mass and strength.
A study conducted by Amory and others (200) suggests that treating men with testosterone before knee replacement improved functional independence afterward. The age-related decline in serum testosterone levels is also correlated with a decrease in the number of Leydig cells in the testes and with a decrease in testosterone secretion by Leydig cells in response to stimulation with human chorionic gonadotropin. These concerns are due to the well-known action of testosterone to accelerate active prostate cancer and to the high prevalence of early-stage prostate cancer in older men. Research has shown that, despite differences in diet, vegans and meat eaters often have the same levels of testosterone.
However, it's generally uncommon for men to naturally have high testosterone levels, so most cases involving high testosterone levels are usually due to external causes. Low testosterone levels in women can also cause fertility problems, in addition to bone weakness and loss of libido. Therefore, you can see that older men may have lower testosterone levels than the average of men in general, while still enjoying good health in general. After ten years, normal testosterone levels for men over 50 would have dropped by 10%, and by age 70, their testosterone levels are 30% below what they were at 40. While the effects of testosterone on younger men are well described, the effects of testosterone replacement therapy on men over 60 are still understudied.
While some clinical trials have seen an association between testosterone insufficiency in older men and an increased risk of death, the exact effects and consequences of testosterone replacement therapy, specifically in older men, remain unclear. Three studies observed a substantial increase in strength after treatment with testosterone, and all of them used slightly higher doses of testosterone than replacement doses. Rarely, tumors in the adrenal gland or testicles can also cause increased testosterone levels. Your doctor may recommend making changes here to see if that improves your symptoms before suggesting treatment for low testosterone levels.
Because testosterone is essential for fertility, energy levels, and muscle and bone strength, low testosterone levels can affect these areas of health...
