However, the human trials produced mixed results. A study researching the effects of DAA supplementation in 24 males with at least two years of resistance training suggests this technique either showed no significant changes or reduced testosterone levels based on the dosage.
The authors of a review examined findings from 25 randomized controlled trials that looked at the effects of DHEA supplementation in 1, men. The authors conclude it led to minor reductions in body fat, but no improvements in testosterone. A review also states there is limited evidence to suggest that DHEA supplementation increases testosterone levels.
While testosterone replacement may help alleviate the symptoms of hypogonadism, it may not produce the same effects in people with naturally declining testosterone levels. People who inject testosterone may experience pain, swelling, or bruising near the injection site.
Topical testosterone gels and patches can also induce allergic reactions at the application site. However, the risks of TRT may outweigh its potential benefits. The FDA does not regulate testosterone supplements, meaning that supplements vary widely in quality, purity, and dosage. According to the FDA , there is a link between some bodybuilding supplements, as well as products marketed as testosterone alternatives, and the following adverse effects:.

What is testosterone? Testosterone therapy may make sense for women who have low testosterone levels and symptoms that might be due to testosterone deficiency. It's not clear if low levels without symptoms are meaningful; treatment risks may outweigh benefits. However, the wisdom and effectiveness of testosterone treatment to improve sexual function or cognitive function among postmenopausal women is unclear.
People with normal testosterone levels are sometimes treated with testosterone at the recommendation of their doctors or they obtain the medication on their own.
Some have recommended it as a "remedy" for aging. For example, a study from Harvard Medical School in found that even among men who started out with normal testosterone results noted loss of fat, increased muscle mass, better mood, and less anxiety when receiving testosterone therapy. Similar observations have been noted among women. However, the risks and side effects of taking testosterone when the body is already making enough still discourages widespread use.
Testosterone is so much more than its reputation would suggest. Men and women need the proper amount of testosterone to develop and function normally. However, the optimal amount of testosterone is far from clear. Checking testosterone levels is as easy as having a blood test. The difficult part is interpreting the result.
Levels vary over the course of the day. A single low level may be meaningless in the absence of symptoms, especially if it was normal at another time. We need more research to know when to measure testosterone, how best to respond to the results and when it's worthwhile to accept the risks of treatment.
