My belief (shared by many in this group) is that ALL men undergo some changes post-vasectomy. Some dramatic including pain and other debilitating issues as a result of nerve damage. Most undergo unnoticeable changes in a race against the clock of life.
In the best case, you get a vasectomy at 40, the changes are small and unnoticeable, and you die at 85 or 90 of other natural causes. But, there WERE changes going on in your body such as compromised epididimides.
In other cases, even without pain, the changes never get related to the vasectomy that occurred, say, 20 years prior. For example, @Choohooo cited a case where sperm was found in a man’s carotid artery as a source of blockage. How the hell does that happen?
Kevin Hauber’s book cites many complications of vasectomy that, coincidentally, my father and father-in-law both had. My father had a vasectomy at 40-45 and went downhill healthwise starting around 55. He died at 75 after being basically immobile for his last 10 years. I cannot prove the vasectomy caused his ailments, but his mother lived 'ti 93 and his father 'til 85. Many of the complications my father had, such as abdominal aortic aneurysm, are cited as increased incidences in Kevin Hauber’s book.
After my vasectomy, in addition to pain onset 8 months post-vas in October 2005, my PSA shot up to 4.2 and my testosterone dropped to 285-325, equivalent to an 80 y/o man. I was 40. I had a reversal in June 2006. Today, at 53, my last 3 PSAs have been in the 0.2 - 0.7 normal range, and my Testosterone has steadily increased from 405 in 2008 to 654 in 2017 to 764 this year despite, now, being 53. My GP sees all the data, shakes his head, and mentions my case to any man who asks him about vasectomy. No, I’m not juicing, I’m RECOVERING from vasectomy still 13 years later.
About 27 months ago, I started this, my 3rd, bout of pain. SInce April 2016, I’ve had 2 spermatic cord blocks at the PUR Clinic in Orlando. I’ve also had a block of the ilioinguinal nerve, a block and pulsed RF of the genitofemoral nerve, and two blocks and one pulsed RF of the pudendal nerve at the Cleveland Clinic. Bet your and your husband have never even heard of those 3 nerves, but they all innervate the scrotum and can be damaged by vasectomy.
I’ve also spent over $3,000 on drugs my insurance won’t cover. None of this includes the cost of living in chronic pain for 2+ years. Thankfully, this last cord block with botox appears to be working a my pain is down 75-80% since late June. The last 2-3 weeks have been the best since this bout began, but the toll on me has been extraordinary.
Again, the probability of your husband or any single man suffering our consequences is small, but if you “draw that short straw”, you’re screwed. It’s not worth the risk.
BTW, we ended up with a post-reversal baby in 2007, the one we were trying to avoid, close to age 43. We cannot imagine our lives without her, our 4th daughter (hence my user name). I’ve learned not only that vasectomy isn’t worth the risk but it prevents joy a couple cannot conceptualize.
