Erythropoiesis is the process of producing red blood cells in the bone marrow. Testosterone plays a role in stimulating this process, which is why TRT can lead to an increase in red blood cell count.
This increase can be beneficial—it helps improve oxygen delivery to muscles and tissues, which can enhance energy and endurance. However, if red blood cell levels become too high, it may lead to complications like thickened blood or an increased risk of clotting.
That’s why regular blood monitoring is essential during TRT. Your doctor will keep an eye on your levels to ensure they stay within a safe range, making adjustments to your treatment if necessary.
