Study States That Testosterone Replacement Drug Prostate Cancer Risk “Urgently” Needs Additional Research

A recent experiment on rats suggested that testosterone medication may increase the risk of malignant tumor growth on the prostate.  This troubling conclusion has prompted an urgent call for additional research with regards to this potential testosterone replacement therapy side effect.  While no connection has yet been made with regards to testosterone replacement drug prostate cancer risks in humans, numerous unrelated studies in the past have found similarities in the studies of rats and human beings.  This study comes to the opposite conclusion of other testosterone drug prostate cancer studies done recently.  Inconsistent results could create uncertainty in the medical community.  These inconsistent results could also create a rising level of concern among consumers.

The study, a link to which can be found here, was done by a professor at the University of Illinois at Chicago.  The study analyzed rats that were separated into four groups.  One group of rats was given testosterone medication and N-nitroso-N-methylurea, or MNU, which is a carcinogen.  A second group of rats was given nothing but testosterone.  A third group of rats was given just MNU.  A fourth group was given nothing at all.  Each group was measured for the likelihood of developing tumors on their prostates.  The research led to the following results:

  1. The group of rats given nothing experienced no prostate cancer.
  2. The group of rats given just MNU experienced no prostate cancer.
  3. The group given both MNU and testosterone showed an increased rate of prostate cancer by a factor of between 50 and 71 percent.
  4. The group of rats given just testosterone showed an increased rate of prostate cancer by a factor of between 10 and 18 percent.

These findings clearly affected the researcher, as he wrote in his description that, “These findings have potential significant public health implications for the use of testosterone therapy in men.”  In addition, other advocacy groups have strongly called for additional research in this area in order to more clearly define these potential testosterone prostate cancer risks given the existence of contradictory studies.

Testosterone Replacement Therapy Side Effects

If prostate cancer and the use of testosterone replacement therapy medications were linked, it would only add to the concerns already associated with men who undergo testosterone replacement therapy or TRT as it’s commonly known.  Several studies have already been published with regards to the risks associated with the use of TRT and the potential for heart attacks and strokes.  The FDA has even held meetings on this very topic.  Of particular concern is the fact that millions of men in the United States have undergone this treatment, potentially exposing an enormous number of them to serious physical harm.
