Why Does Saliva Kills Sperm?

Feb 22, 2021 | Fertility

Let’s debunk the myth!

Sorry to spoil fun. Saliva isn’t exactly sperm friendly and has been found to have slight spermicidal activity and antibacterial effects. Research from Fertility & Sterility Journal found that when saliva was added to normal semen, it induced a “shaking movement” in 12 percent of the total sperm population {1}. It only happened in high concentrations of saliva, but researchers did find that their progression and sperm motility (their ability to swim) was significantly reduced! Their conclusion was that saliva had a “deleterious effect on sperm motility and activity” and should not be used as a vaginal lubricant.

So save the oral sex for days when you’re not ovulating 

Other Lubricants to Avoid!
👉🏻 A UCLA study published in 2013 found that women who used petroleum jelly or baby oil as a lubricant were more likely to end up with bacterial vaginosis or a yeast infection. If you are prone to candida steer clear of both.
👉🏻Researchers found that KY alters the pH balance of the vagina and immobilises sperm, literally stopping them in their tracks.

If you do use a lubricant, please choose one that’s been shown in studies to be safe and sperm-friendly!
