Saliva kills sperm?

EricaOO · February 2013

Good morning all,

I'm almost embarrassed to ask this question even if you all are internet strangers. Saliva is the primary lubricant when it comes to sex with my H. Through stalking these forums and other research I've done on the internet, I've learned that the PH in saliva is not good for sperm (deadly actually) and that many of you use Preseed instead.

Do we know how detrimental saliva really is to conception? Do you all avoid that at all costs?

Out of all lubricants, saliva is actually the worst for sperm. Check out this article, and I'd suggest you try preseed instead of spit:

We always need lube so I got Preseed right off the bat when we started TTC. I was slightly conscious of the saliva thing but not too worried about it. Last cycle (#7) I decided that from now on, no oral during FW. It's really just one more thing I can do to try and help our chances, so why not?

I avoid using spit and oral sex during the time I'm fertile. There are certainly stories of people who became pregnant despite saliva use but I don't see any point in making TTC any harder then it already is.

nooB question. The other night I started out our bang sesh with oral sex and told my DH to wipe all the spit off and use the sheets to dry it off (we washed after). But then after the oral and the drying we BD. Was that a bad choice or are we ok because we dried it off first??

There are plenty of people that still get KU after sex that starts out with some knob-slobbing. Unless you are saving all of your saliva for use during sexy time, you should be ok.

Thanks!!

This. I remember reading about the studies that showed that saliva kills sperm, and they basically put some sperm in a beaker full of saliva and then checked to see how many were still alive after several minutes (which grosses me out just thinking about it.) The amount that is left over from oral sex is not really significant (at least not for most people.) Think about it this way - if saliva was THAT effective at killing sperm, the condom industry would be in big trouble. Everyone would just use a little spit to prevent pregnancy.

And for anecdotal evidence that is proof of nothing - my son was conceived after some major saliva swapping.

i got pregnant using saliva.

if saliva could be used as birth control we wouldn't need birth control pills and condoms...
