“You mention vasectomies in this post. I have had one. I still ejaculate semen, just not sperm (unless I am mistaken). After reading your post today, I was toying with the idea of having a reversal. Then I read the article. According to the article:
And that is a rather odd omission in the biological literature indeed, since there could hardly be anything more obvious in Darwinian terms than the fact that semen is, almost by definition, naturally designed to get into the chemically-absorptive vagina. Bear in mind that although they are often conflated in everyday parlance, along with many other less scientific terms, “semen” is not the same thing as “sperm.” In fact, you may be surprised to learn that only about 1 to 5 percent of the average human ejaculate consists of sperm cells. The rest of the ejaculate, once drained of these famously flagellating gametes, is referred to as “seminal plasma.” So in discussing the chemical composition of semen, it is the plasma itself, not the spermatozoa, that is at issue.”
You are correct, a vasectomy blocks the route sperm takes to join up with the rest of the semen. When a man with a vasectomy ejaculates, he ejaculates sperm-free semen.
If you have had a successful unproblematic vasectomy, I don’t advise a reversal unless you’re seeking to have more children.
My general concern with vasectomy is that some 3-30% of men have long term pain from the proceedure. If you have had a vasectomy and don’t have pain, then this isn’t a concern for you.
My other concern with vasectomy is that some unknown (but likely very small) quantity of men suffer a marked reduction in their total ejaculate much greater than just the loss of sperm that would be in there. If that is the case there’s likely minimal transmission of the anti-depressant hormones that are in the seminal fluid. If this isn’t a result of your vasectomy, then it isn’t a concern for you either.
Like all surgical procedures there is a risk for infection and other complications. I don’t mean to over state that aspect though. Most modern surgeries of all types go quite well in terms of infection and vasectomy is minimally invasive.
Basically vasectomy is advertised as simple, easy and very safe. For many men their vasectomy goes extremely well. For some other men it really doesn’t. It’s just not as perfectly safe as it is made out to be.
I also “just have a hunch” that vasectomy is a factor in some divorces. That’s all I’m saying, it’s a hunch, nothing more. There’s no science on this issue that I know of. Which is kind of concerning.
Basically the reasons to have a vasectomy reversal are to try and have more children, or to try and repair a botched vasectomy.
