The Role of Autophagy in Erectile Dysfunction

Autophagy is a process where cells degrade and recycle their own components. It's like a cellular spring cleaning, removing damaged parts to keep the cell healthy. Recent studies suggest this process plays a role in erectile dysfunction (ED). ED can result from various issues like diabetes, nerve damage, or aging. Autophagy seems to help manage these problems by improving the function of cells in the penis, such as endothelial and smooth muscle cells. Researchers are exploring how autophagy can be manipulated to treat ED. By understanding how autophagy works in penile cells, they hope to develop new therapies to improve erectile function.

  Autophagy plays a significant role in maintaining the homeostasis of corpus cavernosum endothelial cells (CCECs) and determining their survival and death, influencing ED, particularly in diabetes mellitus-induced ED (DMED).
• 2
  The balance between autophagy and apoptosis in corpus cavernosum smooth muscle cells (CCSMCs) is crucial in various forms of ED, with proper autophagy removing unwanted cellular components and maintaining cell survival.

  Autophagy plays a significant role in preventing penile fibrosis by degrading collagen macromolecules and clearing abnormal macromolecular depositions, thereby maintaining intracellular homeostasis.
