TOPIC: Does filler enhance/inhibit blood flow?

I have a penile implant and considering filler, either HA or Ellanse. Penile blood flow is slightly reduced for me because I have solid plastic tubes in the middle of my shaft. Do fillers tend to somewhat reduce blood flow in the penis or is it unaffected? Or even enhanced?

Speaking as someone without a penile implant who has had two rounds of PMMA injected (21cc then 15cc) recently, there is no effect on blood flow, boner quality, urination, etc. That’s from an end-user perspective - hopefully someone else will chime in with a scientific explanation for why one shouldn’t expect a change in blood flow.

I do recall at least one Progress Report where the author has an implant and also filler (which type escapes me). I’ll link it when I find it.

anecdotally: not at all

speaking from intuition rather than any kind of medical background:
looking at some of these diagrams of the layers of the penis and the vasculature I guess i could /hypothetically/ see a sort of compression against the vasculature especially while things are swollen, and before the skin stretches. But nobody here has reported anything along those lines that I've read (others have been here far longer).
Maybe if you had a severe Venous Leak? Dunno, proper Urologist question. I would imagine as far as the corpus cavernosum goes the mechanisms that cause blood infil and stop blood exfil are way stronger than slight inward pressure could produce. Likewise e.g. the dorsal vein, the arteries, you'd have to do something pretty obscene to affect those, and i suspect you'd hit other issues long before they were affected.

And of course the tissue that's created around the filler itself vascularizes - i just can't see as a layman any real-world commonplace things someone would do with filler that would restrict blood flow.

There is nothing I've read in over 10 years here or elsewhere online & literature that suggest medical-grade dermal fillers when properly injected have any notable adverse impact on blood flow or Erection quality.
