The Melky Cabrera Story May Discourage Men Who Could Benefit From Testosterone Therapy

Posted on August 21, 2012San Francisco, CA – Though the Giants’ Melky Cabrera has garnered media attention since testing positive for testosterone use in July, he is likely not the only baseball player using testosterone to make it in the “big leagues”. The use of testosterone is unfortunately rampant amongst athletes, across many sports and extending to the Olympics. As testing has become more prevalent, athletes have become more adept at avoiding detection. Altered anabolic “steroids” are easy to detect and have therefore become less popular; while testosterone — identical to what is naturally produced by the body — is much harder to detect, and much more widely used. Special ratio calculations, like the testosterone to epitestosterone ratio, will pick up some testosterone use, but will not detect off-season use, or the use of some fast-acting testosterone creams and gels. The newer carbon isotope ratio tests are more sensitive, but are not widely used due to limited availability and high cost.Millions of dollars are already spent each year in an attempt to curb performance enhancement amongst athletes, yet the vast majority of use probably still passes under the radar. When a test does come back positive it is headline news: a steroid “scandal”.

On the other hand, testosterone is a prescription medication that, when used correctly under a doctor’s supervision, can provide great benefits to men with low testosterone production. It is also a highly controlled and regulated medication due to its potential for abuse amongst professional athletes. By limiting the number of prescriptions doctors write, the supply of testosterone for illegitimate use is limited. Unfortunately, men with a legitimate medical need for testosterone therapy pay the price in limited availability and higher costs. In addition, media attention on these pro-sports steroid scandals casts testosterone therapy in a poor light, discouraging men who could truly benefit from treatment from seeking it.
