Can doctors tell me what does taking testosterone booster do?

Testosterone : Otc "testosterone boosters" do little or nothing to change you testosterone levels. Save your money, get your level checked and if it is legitimately low see a urologist or endocrinologist for treatment.

Shrink your wallet: There are no testosterone "boosters", no matter what the internet and tv and your friends may tell you. The only way to "boost" your testosterone is through a healthy life style, proper nutrition, exercise, and avoidance of toxins like alcohol and tobacco. Save your money, and your health.
