Dr. Yoshi Sato, the Vice President of the Japanese Society of S*xual Medicine, and professor at Sapporo Medical University presented the most important research for men with ED of all causes. His study used the Performance rings on men with very profound ED, men who were unable to attain full hardness, even using PDE5 medications (like Vi**ra) and ICI (Intercavernosal injections like Trimix). These are men who have typically run out of options short of surgery.
The results were striking.
The Key findings
1. Men with moderate ED had a 100% response rate with the ring. Men with an Er****on Hardness Score of 3, meaning hard enough for pe*******on but not fully hard, responded completely to the Performance Ring. This is the most common presentation of physical ED.
2. Men with severe ED had a 50% response rate to the ring. Men with an Er****on Hardness Score of 2, meaning not hardenough for pe*******on, still responded at 50%. This was unexpectedly high even to the researchers.
3. Er****on duration increased by 20 minutes on average.
4. 67% of men were able to continue in*******se after ej*******on on average for 12 minutes.
