Summary
Brief summary
This study aims to assess the effects of testosterone on endothelial progenitor cells numbers and function in men. By understanding the effects of testosterone on endothelial progenitor cells, we may be able to better understand the potential role that male sex hormones may play in maintaining heart and blood vessel function in men. This research may ultimately lead to new treatments to help with heart and blood vessel repair.
To Public:
This study aims to assess the effect of male sex hormone on the male stem cells. By understanding the effect we may be able to use male sex hormone to maintain human heart and blood vessel function in men.
