What is the Origin of TRT-induced Erythrocytosis?

The association between androgen administration and increased red blood cell production has been known since the therapeutic use of testosterone began, as testosterone was even used historically to treat certain types of anemia. The term became a specific clinical concern in the context of TRT protocols as higher-dose or less frequent injection regimens were shown to produce significant peaks in testosterone, leading to a greater stimulus of erythropoiesis.

What is the Mechanism of TRT-induced Erythrocytosis?

The primary mechanism involves testosterone's direct and indirect stimulation of erythropoietin (EPO) production, a hormone synthesized mainly by the kidneys that promotes red blood cell formation in the bone marrow. High peak testosterone concentrations, often seen shortly after intramuscular injection, provide a potent, supra-physiological signal for EPO release. Furthermore, testosterone can sensitize bone marrow stem cells to EPO. Management often involves adjusting the TRT dosing frequency or route to minimize peak levels and reduce the erythropoietic drive.

TRT-induced Erythrocytosis

Meaning

TRT-induced Erythrocytosis is a recognized clinical side effect of Testosterone Replacement Therapy (TRT) characterized by an abnormal increase in the total red blood cell mass, specifically indicated by elevated hematocrit and hemoglobin levels. While a modest increase in red blood cells is a known effect of testosterone’s erythropoietic stimulation, an excessive rise can increase blood viscosity, raising the theoretical risk of thromboembolic events like stroke or deep vein thrombosis. Careful monitoring is essential for patient safety during hormone optimization.
