“You put some emphasis on ejaculating into the womb so that nutrients contained in seminal fluid can be absorbed by your female partner.
We all know that the primary purpose of the vasectomy is to eliminate semen from the ejaculate. But does the vasectomy also eliminate/reduce these other nutrients?
Coitus-interruptus has been our/my preferred choice of BC (and have been really successful over my 31 year LTR – only 2 kids, youngest is now 22) and had been considering getting snipped recently – if only for the benefits to the wife. Was not cognizant that semen absorption could be so critical to a LTR – but I wasn’t aware of a lot of relationship dynamics till I stumbled upon your MMSL blog (By the way – love the Primer!)….
Of course, now that she’s 50 (I’m 52), menopause is ‘just around the corner’. So soon, she’ll be ‘sterile’. So should I hold off on the operation? No, don’t expect you to answer the question (though your opinion is welcome). But I don’t want to ‘screw the pooch’ if the operation does more than eliminate semen from the ejaculate….”
Minor correction of terms first. The ejaculate is about 5% sperm, and 95% semen. So the idea of the vasectomy is to stop the sperm ever getting mixed in with the semen. So after a vasectomy you should ejaculate nothing but the semen with just a minor loss of total ejaculate volume.
What’s in the semen should remain fairly unchanged, though there’s also some testosterone in semen – the purpose being to trigger her sex drive further. Considering the primary production location for testosterone in your body is in your testicles, blocking the most obvious route for testosterone to get into her vagina by the vasectomy, I would assume it quite possibly reduces the testosterone that goes from you to her via the semen.
However, please read these posts…
What you are rolling the dice on is… a handful of years until she hits menopause vs. the remainder of your sexual life. Having gone this far successfully as you have, I would beg you not to have a vasectomy at this point. You’re gambling two or three years vs. hopefully twenty to thirty years.
A vasectomy may very well turn out 100% perfect for you, but I simply see no reason to risk permanent pain or worse, when you could simply use what you have done until now or condoms for a couple more years. Surgical is always the last option.
As I say in those posts – there is so little science on the aftermath of vasectomy that all I can offer is a hunch that it isn’t safe as they say it is. Many couples do just fine with vasectomy and love it. My worry is that if you don’t love it, well… you’re pretty much having to go back under the knife to fix it. Even then you may be hosed… (Wikipedia)
“One study found that epididymectomy provided relief for 50% of patients with post-vasectomy pain syndrome.Orchiectomy is recommended usually only after other surgeries have failed.”
So… please don’t do it without extreme thought and your own research.
