Dr. Neal Rouzier is arguing that erythrocytosis is NOT polycythemia. He recently presented at this Conference: http://worldlinkmedical.com/wp-cont...-Century-Welness-Medicine-Course-Brochure.pdf And in a preview comment he said: Dr. Rouzier discusses here at minute 46:00 forward the distinction between erythrocytosis & polycythemia. Actually, the whole lecture is kind of interesting. If Dr. Rouzier is correct, then there are three question in my mind: 1. does erythrocytosis need to be present at every moment for the upregulation of nitric oxide? Suppose, for example, one goes off androgens. Now, the hormone and activity of erythropoietin will be decreased, presumably? But your red blood count would still be elevated, presumably for some time. Is this a valid concern? 2. Will the Red Cross and other centers will not allow TRT patients to donate blood with elevated hemocrit? 3. Will pcps/doctors/hospitals continue to see androgen->erythrocytosin-mediated elevated hemo as a dangerous “condition”?
