Do Personal Lubricants Like Astroglide and KY Jelly Kill Sperm?

The Problem With Regular Personal Lubricants + Sperm Friendly Options

Can lubricants like KY Jelly kill sperm? Sort of. They certainly can't be considered sperm friendly.

While you can't use them to prevent pregnancy (you'd need spermicide for that), they are not a good choice when you're trying to get pregnant.

Quite a few studies looked at the effect various lubricants have on sperm.

The studies looked at..

  • how well the sperm swim (motility)
  • whether or not DNA damage occurred
  • whether sperm were still alive

Popular lubricants like KY Jelly, Astroglide, and Replens were found to inhibit sperm movement and even kill sperm.

Every study I looked at cautioned against the use of common lubricants for couples trying to conceive.

To be clear, we are talking about lubricants that are not specially made to be fertility friend.

For example, Astroglide does sell a fertility friendly version of lube called Astroglide TTC. The studies showing problems with Astroglide's regular product wouldn't apply to their trying to conceive product.

Sperm Friendly Lubricants

There are lubricants that have been made to be fertility friendly. The most popular sperm friendly lubricants are PreSeed and Conceive Plus.

It may be possible to use raw egg whites as a personal lubricant, and some people do it. The idea is that it would be closest to nature's fertility friendly lubricant, egg white cervical mucus.

But there is a risk of allergic reaction (if you have an allergy to eggs) and possible salmonella poisoning.

Plus, it's kind of messy. I wouldn't do it.

Canola oil and plain baby oil are sperm friendly options. But they may lead to vaginal infection or irritation.

In case you're wondering, saliva is not a sperm friendly option.

The acidity is harmful to sperm.

The Bottom Line on Lubricants When Trying to Get Pregnant

Unless a lubricant has been specifically made for trying to conceive, you should be wary.

Both water- and oil-based lubricants have been found to interfere with sperm movement, and some kill or alter the DNA of sperm.

It's also important to mention that a lack of arousal fluids or cervical mucus may indicate a fertility problem.

If this is a common problem for you, and you have not mentioned it to your doctor, be sure to speak up. It may help your doctor treat your infertility.
