Question On Implants and Deflated Glans

[Sean762]

So my limited understanding is that an implant will inflate the shaft but not the glans.

Would pumping up the implant, followed by placing the penis in a VED at say 5 inches of Hg for 5-10 minutes cause the head to fill normally and stay somewhat filled (with or without an erection ring) for more 'normal' sex with a partner?

The VED Will engorge the glans,but I have to use two rings to keep the blood in place.I have a venous leak thst caused my ED.In fact the VED engorges my dick and makes a big difference.If you don’t have a leak it should hold it.

I had venous leak, but I still get glans engorgement. Its really all individual. Often Viagra will help with it too.

I'm not sure venous leak would cause the total loss of engorgement in the glans which comes from the corpus spongiosum (correct me if Im wrong)

Venous leak isn't leaking veins. My understanding is venous leak is caused by tissue degeneration in the corpus cavernosum that can no longer hold enough blood to seal an erection and block the drainage veins. Therefore the blood "leaks out"

But the glans is engorged by the third body (spongiosum) , so if the two cavernosal implants are sealing the erection and there is sufficient release of nitric oxide from arousal shouldnt there be some stability of engorgement of the glans?

[gjmjoe017]

Not sure but I can tell you my glans stays engorged with two rings on and won’t without them.Pretty much tells me it’s due to the leak!

[Mark74]

If you don't ejaculate for a period of time and there is a build up of sexual energy does that help at all with engorging the glans?

[MARKOS2018]

I agree with Him re engorgement of the glans. The under the shaft vein runs to the glans I think and that helps engorge the glans. Arousal, and plenty of that will help keep the blood there and the shaft will be rounder as a result.

Rings do help and the glans gets bigger and better. The rings keep it there.

I use the VED at times after I pump it up and will ring it... and the wife will do a

It isn't always this. In some cases of venous leak, especially where people have never been able to have proper erections throughout their life, it is due to blood leaking out from veins in the crus of the penis (which is the part of the penis buried deep inside the body).

For example, I have a venous leak, but the Doppler ultrasound showed no scarring or fibrosis in my corpora.

I have often used the concept that the implant inflates the corpus cavernosum inside the tunica albuginea. This is not unlike those fabric tubes being blown full of air and dancing around outside of car lots and furniture stores. But to be hydraulically correct that concept is not totally accurate. The implant gets inflated and supports the tunica (the tube of fibrous tissue inside the penis that is normally filled/pressurized/supported by the corpus cavernosum - the porous erectile tissue).

The implant operation often removes the corpus cavernosum tissue, replacing it with the implant. (Some surgeons use a "tissue-sparing" technique, but even this leaves the cavernosum pretty much ineffective for erections.)

So, the implant itself stiffens by the pressure inside it. This stiff implant causes the tunica and the penis to be straight and resistant to bending (erect), but not necessarily "inflated". As I understand it, the AMS implants resist expanding width-wise because their structure is of a woven polyester cloth covered inside and out by medical grade silicone. Thus cannot expand much in girth. The Coloplast devices are made of a proprietary material called "Bioflex" which can stretch a bit, this may be able to press against the sides of the tunica, simulating inflation of the tunica (and thus, the shaft).

The implant stiffens the shaft and expands it somewhat, but the glans is completely unaffected. However, with a stiff shaft underneath the glans, stimulation often will cause the glans to engorge (note that the blood supply that engorges the glans is separate from the blood supply that used to engorge the corpus cavernosum and the glans blood supply is usually unaffected by ED). Also note that the shaft outside the tunica is engorged in the same way as the glans. The tissues in the glans and shaft that engorge is called the "spongiosum".

Except for that nuanced correction, your understanding is essentially correct.

Spongiosum engorges by a different mechanism than the cavernosum in an erection of a normally operating penis. Spongiosum engorgement is independent of the erecion, whether by engorgment of the cavernosum or inflation of an implant.
