Research shows IPP tips are too sharp

[Doggedly_positive]

This research paper appears to demonstrate that the cylinder tips are sharper than the actual corpora cavernosa tips, leading one to wonder why they have been designed to be so sharp.

Would there be fewer instances of erosion if the IPP or malleable tips conformed more closely to those in the corpora?

As an engineer, I've always doubted the design of the tips, believing that the point load at the tip is much higher than it needs to be and that a blunter tip would not be as likely to penetrate into the glans so easily.

The same thought applies to the RTEs, which appear even sharper.

Anyone have any more information?

Did you read it? "Our findings suggest that anatomically accurate corporal tips appear to be relatively blunt and that the new Titan silicone tip penile prosthesis more closely resembles the human corporal tip."

Also it's more than 13 years old. I am pretty sure the implants we are getting now have all been improved since then.

Yes, of course I read it. That's why I posted it.

I don't know about the Titan, but the Rigicon and the AMS both exhibit sharper tips and RTE tips than the corpora that were measured. Did you see them?

My comment stands and I can see no reason for them to be the shape that they are.
