Alright, let’s get into something I spent a bit of time looking into myself, because, well, it’s a question a lot of guys have, even if they don’t always ask it out loud. We’re talking about vasectomies and whether they can cause erectile dysfunction, or ED.

My Own Digging into the Vasectomy and ED Question
So, this whole thing started when a good friend of mine, let’s call him Dave, was considering getting “the snip.” He was done having kids, his wife was on board, but he cornered me one afternoon, looking all worried. “Man,” he said, “what if it, you know… stops working?” He meant his equipment, of course. And honestly, I didn’t have a solid answer for him right then and there, just some vague ideas.
That got me thinking. I’m the kind of person who, if I don’t know something, especially if a friend is worried, I gotta find out. So, I started my own little “project” on this. No white lab coat, just me, some reading, and a few conversations.
First off, I chatted with a couple of guys I know who’d actually had it done. One guy, Jim, he’s a straight shooter. I asked him flat out. He just laughed. Said the only thing that changed was he wasn’t worried about accidental pregnancies anymore. If anything, he said, things got a bit more relaxed and fun in the bedroom for him and his wife.
Then I did some digging, reading up on what doctors and actual studies say. And you know what? The overwhelming consensus seems to be that a vasectomy itself doesn’t cause ED. It just doesn’t. The procedure is pretty minor these days, from what I gather. They’re basically just rerouting the plumbing for the sperm, not messing with the hydraulics, if you get my meaning.
- Your ability to get an erection? Comes from blood flow, nerves, hormones – stuff the vasectomy doesn’t touch.
- Your testosterone levels? Unchanged. That’s what drives your libido, mostly.
- The physical act? Still feels the same.
The whole point of the vasectomy is to stop sperm from getting into the semen. That’s it. It’s about fertility, not your ability to perform. So, you’re not going to suddenly develop ED because of the procedure itself.

What About the Stories You Hear?
Now, I did come across some stuff saying that ED is a common issue. Sure, it is. But it has tons of causes: stress, anxiety (maybe even worrying about the vasectomy!), other health problems like diabetes or heart issues, lifestyle choices, all that jazz. So, if a guy has a vasectomy and then develops ED, it’s far more likely to be one of those other things kicking in, maybe coincidentally.
I also saw a figure, something like 5% of guys who get a vasectomy end up getting it reversed. That sounded like a “gotcha!” at first. But when I looked closer, the reasons for reversal were almost always because they changed their minds about having kids later on, not because the vasectomy somehow broke their machinery. Reversing it is a much bigger deal than getting it done in the first place, by the way.
So, my takeaway from all this?
After my little investigation, I told Dave what I found. That the vasectomy procedure itself is highly unlikely to cause ED. He seemed pretty relieved. He went ahead with it a few months later. Last I heard from him, everything’s working just fine, and he’s a lot less stressed.
Of course, everyone’s different, and if someone is super anxious about it, that anxiety itself could temporarily affect things. But the physical act of getting a vasectomy? The evidence just isn’t there to link it to causing ED. It’s one of those myths that seems to hang around.
So, that’s my two cents, based on what I dug up and the folks I talked to. Hope it helps someone else out there who’s wondering the same thing!
