As the sales of drugs like Viagra and Cialis grows, a new gene therapy is currently being tested as an alternative. The gene changes a protein that will cause the smooth muscle to relax and increase circulation to the non-erect penis, increasing its function.

Once proven safe, tests to find out exactly how effective it is in improving erectile function will then be able to begin.
