There is Zero evidence in the medical literature supporting phlebotomies in men on TRT. In decades of men having a secondary erythrocytosis it has never been shown to cause harm. We will discuss how medicine can get things wrong on the next podcast with Rick concerning prostate cancer. For decades men have been deprived of testosterone after being treated for prostate cancer unnecessarily. This deprivation of treatment was based on one physician's observation of one patient in the 1940s. We now know that man with active prostate cancer confined to the capsule as well as men who have been treated for prostate cancer can take testosterone with no worsening of the disease. Clinics have been phlebotomizing men for decades not based on any harm caused by TRT, but because they think that the secondary erythrocytosis you get from testosterone causes the same issues one would see in a person with polycythemia vera. It does not, as polycythemia vera causes an increase in red blood cells, white blood cells, and platelets and of course platelets clot. There is also a quantitative and qualitative change in red blood cells in people with polycythemia vera. So once again we get to the three myths, which are 1.) you must block Estradiol, 2.) that you have to donate blood because if you don’t there will be harm, and 3.) that it causes or worsens prostate cancer.
