Will the corpus spongiosum still work after implant?

Postby KaBoom » Thu Jul 09, 2026 5:00 pm

The cylinders replace the corpus cavernosum and thats the part the implant works its magic on.

However, the spongiosum, the tube that runs along the bottom side, is still the same same as before.

Its only been several months, but it does not seem to inflate at all anymore , giving a bit more of a narrow oval shape in the erectile state in my case.

Does it eventually get back to normal with cycling and time? or would one need to include a viagra to get it going too?

I wouldn't make any conclusions until about a year in. Several months is still quite early.

It shouldn’t be affected by the implant. However, it could be affected by whatever was driving your ED in the first place.

Cycling would not have an effect on it.

The spongiosum is not altered by implant surgery but the nerves supporting its function can be affected by the swelling and edema outside the CC. Generally speaking nerve trauma takes about a year to fully repair.

Rule of thumb is if you have good spongiosum and glans engorgement before surgery, you will after. And if it was crap before, expect the same after.

At 9 months I noticed some weak response and around the 1yr mark I was back to my pre surgery condition. Of course some bruise more than others and everyone heals at a different pace so this varies.

And yes, PDE5 inhibitors (like sildenafil or tadalafil) can help with corpus spongiosum and glans engorgement, particularly if your ED is due to cardiovascular (getting blood in) problems.
