AMS CX for a longer Phallus?

Postby ThatTallGuy » Thu May 21, 2026 8:38 pm

I'm set up for IPP surgery in late July but when I asked my doctor which implant he was going to use, he said he will likely use the CX, not the LGX because it's too flexible to be used with a longer phallus. He never mentioned the Titan.

I am 21 cm stretched and 16.5 cm girth with no Peyronie's disease and no other issues so it should be straightforward.

My question is, since the CX doesn't expand or contract lengthwise (only girth expansion), does that mean that my penis will be nearly the erect length even when deflated, or does the CX implant shrink somewhat in length?

Has anyone used the Coloplast Titan in longer lengths with good rigidity? It looks like the LGX isn't used on anyone longer than 18 cm because it's not rigid enough.

Hey TallGuy, a few points:

There is virtually no scientific evidence that an LGX makes your dick bigger. While the implant itself can supposedly theoretically expand lengthwise, that doesn’t show up in the data in erect lengths. If your doc suggests a CX, go with that. Most docs seem to be aware that the claims around the LGX are mostly just a marketing gimmick. At your length I would definitely stay far away from an LGX.

The theoretical lengthening of an LGX has nothing to do with flaccid to erect lengthening. Your flaccid will likely be the same length regardless of CX or LGX implantation. Expect your flaccid to be significantly longer than your current flaccid, usually seems like maybe an inch or so shorter than erect. The experience of most guys is that their flaccid is significantly bigger in most regards than pre-implant.

The conventional wisdom seems to be that Titan is the best for a long penis, as it is better at girth expansion than CX. It may also be preferable from an axial rigidity standpoint, but I am less aware of conventional wisdom on that point. Talk to your doc about it. On the other hand, the conventional wisdom is that a CX has a more natural flaccid that is less hard and prone to dog ears. Which is more important to you might drive your choice.

Your doc may not install Titans; many docs seem to favor one manufacturer. So if that is important to you, consult with a doc that does both or at least does Titans.

Good luck with your process!
