Based on a few things you said in the post above, it doesn't sound like you know much about vasectomy reversal, or vasectomy reversal for pain. Here's some input...
Congestive pvps is a condition where your epididymal tubes are engorged with sperm. In many cases, including studies on humans, rats, and other animals, what I'm talking about has been proven. Some men end up blowing out, leaking sperm, sperm granuloma, etc.
When men are sold vasectomy, urologists generally put a lot of lipstick, and glitter on that part. They say things like, your body will absorb all the sperm as it did before, no problem. It's BS of sorts.
All at the same time, many studies have proven that this engorgement can cause damage to your epididymal tubes, your epididymis, and your testicles in general over time.
So, did I want to be fertile again, and get pain relief? My answer would be yes to both.
I didn't want to be congested anymore. I didn't want to be leaking any longer. I also wanted the electro cauterized ends of my vas's removed, granulomas, metal clips, scarring, and so on removed. Given my sexual side effects post vasectomy, a reversal was just another hopeful plus.
Some men, and probably a lot of mens body's absorb this sperm fairly well in time. Mine doesn't do so great with this.
Far as how one does multiple reversals? That's easy. This is really common in fertility. Some men have undergone as many as 2-3-4 reversals trying to get their wife pregnant.
A vas to vas redo reversal is as easy as cutting your vas's apart again, clean things up well (scarring and such), and put them back together again with micro sutures under a powerful microscope (microsurgery).
Far as what you are saying about not wanting to be fertile again, well, you want something that's not natural, and comes with many risks, and complications. Ultimately, you have to make "educated choices" that are best for you.
I don't know your story, nor your timeline. Hard to say what the deal might be with you. Have you tried papaya seed, or testosterone therapy yet?
Just FYI here, congestive PVPS is not to be confused with PVP, such as nerve damage, rough surgery, etc. Many like to bundle it all together and call it all pvps. Technically, they are not the same conditions.
Hope this helps
