For guys without hypogonadism, a wait-and-see approach may make the most sense. "We just don't have the data to prove that raising testosterone in men who already have normal levels confers any real benefit," says Dr. Robert Mordkin , a urologist in Arlington, Virginia. Furthermore, Mordkin adds, "Natural waxes and wanes of testosterone as we age may have some not yet entirely understood protective effects." In addition to making us better fathers, as the Northwestern study infers, declining testosterone "may lower our vulnerability to prostate cancer at a time in our lives when we're at the greatest risk for it." That said, if you have classic symptoms of hypogonadism – low libido, fatigue, erectile dysfunction – "it's probably reasonable to check your testosterone. And for those guys whose blood levels come under definitions of low testosterone, it's probably reasonable to try the therapy for a while. But that's very different from saying testosterone is the fountain of youth."
Once a diagnosis of clinically low testosterone levels has been determined, what is the best course of action to restore them? The most impelling means for many adults is to receive a course of prescription testosterone replacement therapy. Both research and actual results consistently indicate that the most effective form of therapy is the implementation of a bio-identical hormone replenishment program for individuals whose levels fall well below the average testosterone levels in men by age . The use of these injections, which must be prescribed and supervised by a licensed physician, can fastidiously increase an adult’s deficient hormonal levels over a specific period of time.
