That sounds like a VERY interesting study. There are no tendons in the penis, but there is a suspensory ligament. Stretching and lengthening the suspensory ligament has been theorizedand even practiced in surgical penile enlargement. I suspect that it is not what I want as far as penile growth. I want my suspensory ligament to be strong and supple for better erections, not stretched out and floppy. I need that suspensory ligament to be strong enough to lift my heavy pumped penis into some type of an erect state. I haven't figured out how to strengthen the ligament except for some light jelqing though... maybe you have a suggestion? Either way, that is a cool as hell fucking link and I am gonna check it out.

I just checked it out and it was a study about collagen tissue, not specifically tendons, although that is the title of the study. It seemed that low intensity and high duration force is what was the best for growth. It also suggested that heat was also necessary for the process to be successful. That does not really describe jelqing, but it does describe light pressure and long duration pumping with heat. I just think that the penis is a very important and somewhat complex organ. It resists long term growth because it must maintain it's structural integrity for successful breeding. That has just been my personal experience. That link was awesome and gives me more motivation to keep up my PE efforts and gives me hope for some kind of permanent growth. Thanx Spunkboy!
