No. Full stop, no asterisk. You cannot catch Peyronie’s disease from anyone, and you cannot give it to anyone either — not through sex, not through sharing a towel, not through anything.
I get why the question even comes up, though, and it’s not a dumb one. Peyronie’s often shows up out of nowhere. One week everything’s normal, and then there’s a hard lump you swear wasn’t there before, or a curve that seems to have appeared overnight. That’s exactly the pattern your brain expects from something you “caught” — a cold doesn’t build up slowly either, it just shows up. So the instinct to wonder “did I get this from someone?” makes total sense, even though the answer is no.
So what’s actually going on, if it’s not an infection?
Peyronie’s disease is a connective tissue problem, not an infectious one. Somewhere along the way — usually from small, often unnoticed injury to the tissue inside the shaft — your body’s healing response overreacts and lays down a patch of extra scar tissue (doctors call it “plaque,” which sounds alarming but really just means a dense little patch of collagen, the same stuff scars anywhere else on your body are made of). That patch doesn’t stretch the way the surrounding tissue does, so when you get an erection, it pulls that side tight and the whole thing bends.
There’s no virus, no bacteria, no fungus, nothing that could jump from one body to another. It’s closer to a scar from an old sports injury than it is to anything you’d catch from a partner.
Why the “did my partner give me this” thought is so common
A lot of men notice Peyronie’s for the first time after sex, which makes the timing feel suspicious. But that’s usually not a coincidence in the way it seems — sex is one of the more common moments where the small injury that triggers the whole process actually happens, especially if there was any unusual bending or a position that put more stress on the shaft than usual. It’s not that your partner “gave” you anything. It’s that the mechanical stress of the moment is what set things in motion in a body that was already prone to healing this way.
I’ve heard from guys who genuinely worried their partner had something and didn’t tell them, and honestly, that worry can do more damage to a relationship than the condition itself. It’s worth saying out loud to your partner, too — this isn’t caused by them, isn’t a hygiene thing, isn’t anything either of you did wrong.
What it can get confused with
Part of why the contagious question sticks around is that a new lump on your penis understandably makes people’s minds jump to STIs — genital warts, herpes sores, that kind of thing. Those are different animals entirely: they’re usually soft, often multiple, frequently come with other symptoms like itching or discharge, and they show up on the skin surface. A Peyronie’s plaque is a firm, single lump you feel under the skin, in the shaft itself, and it doesn’t come with the other symptoms an STI would.
If you’re genuinely unsure which one you’re dealing with, that’s a reasonable thing to get checked rather than guess about — not because Peyronie’s is dangerous to anyone else, but because ruling things out properly beats lying awake wondering.
One more thing worth saying
There’s a quieter version of this fear that doesn’t always get said out loud: some men worry less about catching something and more about whether they could somehow be “giving” their partner something just by having sex with the curve or the plaque present. You can’t. There’s genuinely nothing about Peyronie’s disease that transfers, spreads, or puts a partner at any physical risk. The only thing it can complicate is comfort or positioning, not their health.
The bottom line
Peyronie’s disease is something your own body did, not something anyone did to you. It’s not contagious in any direction — you didn’t catch it, and you’re not going to pass it on. That part of the worry, at least, you can safely put down.

FAQ
Is Peyronie’s disease contagious?
No. Peyronie’s disease is caused by scar tissue forming inside the penis after minor injury, not by a virus, bacteria, or any infectious agent. It cannot be transmitted through sex, contact, or any other means, in either direction between partners.
Can I give my partner Peyronie’s disease?
No. There is nothing about Peyronie’s disease — the curvature, the plaque, or the underlying cause — that can transfer to a partner. It carries no infection risk of any kind.
Why did Peyronie’s disease suddenly show up after I had sex?
Sex is one of the more common moments when the small tissue injury that triggers Peyronie’s actually happens, especially with unusual bending or added pressure — not because anything was “caught,” but because that’s when the mechanical stress occurred.
