At this time there is no clear evidence to show that Viagra enhances penile health on the long-term. The other PDE-5 inhibitors, including Levitra and Cialis, have also been shown to improve blood flow into the penis and there is some suggestion that long-term use of any of these three drugs may reduce the risk of cardiac events over time. Until a properly done study is completed, I would not recommend taking daily PDE-5 medication for future penile health, as there is the possibility of side effects and this is quite an expensive medicine. On the other hand, for the man who is experiencing erectile dysfunction, daily to every other daily dosing with these medications may be in order.
