Can testosterone therapy worsen blood clots?

ANSWER

The FDA requires that testosterone replacement products carry a warning about the risk of blood clots in veins. This could increase the risk of deep vein thrombosis and pulmonary embolism, a potentially life threatening clot that occurs in the lungs. Products already carried a warning about the risk of blood clots due to polycythemia, an abnormal rise in the number of red blood cells that sometimes occurs with testosterone treatment. Now the warning is more general to include men who don't have polycythemia.
