Overview

Hand sanitizer, also known as a hand antiseptic or hand rub, is a product that is applied to the hands to remove common germs (viruses or bacteria) in the hands. 

Hand sanitizers are usually available as foam, gel, or liquid. They are recommended for use when there is an unavailability of water and soap or there are other medical concerns.

Hand sanitizer contains ethanol 96% or isopropyl alcohol 99.8%, glycerine 98%, and hydroxypropyl methylcellulose (1 g)

Spermicides are a type of contraceptive designed to kill sperm or stop it from moving. These products can be safely inserted into the vagina before sex.

Hand sanitizer and other households chemical can be harmful to sperm. Some hand sanitizers may contain methanol which can be more toxic.

Let’s find out if hand sanitizer can kill sperm, which other products may also kill sperm, and how to safely use conventional spermicides.

Hand sanitizer & sperm

Sperm cells travel in a viscous fluid called semen, which contains many nutrients that help keep the sperm healthy. Semen also helps to protect the sperm from the acidic environment of the vagina.

Despite the crucial role of sperm cells in reproduction, they are fragile in the wrong type of environment.

Spermicide lowers the chance of pregnancy by reducing the effectiveness of sperm. Conventional spermicides are inserted into the vagina before sex.

They can act as a barrier to prevent sperm from entering the cervix. Spermicides also contain chemicals that reduce the movement of sperm.

Many types of chemicals can kill sperm. For example, hand sanitizer contains ingredients such as isopropyl alcohol, glycerin, and other harsh compounds.

In a similar way that hand sanitizer kills germs, it kills sperm as well. Hand sanitizer may reduce the movement of the sperm cells or kill them on contact.

Can it Kill Sperm? 

One of the first ingredients in many hand sanitizers is isopropyl alcohol. Unlike conventional spermicides applied directly inside the vagina, isopropyl alcohol is not safe for internal use.

Therefore, hand sanitizer should only be used on the hands for the purpose of killing bacteria and should never be applied to a penis or a vagina .

If you have a vagina, you should never use common household chemicals in or around your vagina. The vulva and vagina are very sensitive areas and harsh chemicals may cause burning and irritation (vulvovaginitis) .

If you have a penis, the skin of your penis is also sensitive and just as easily damaged. Never use household chemicals, such as hand sanitizer, as a topical alternative to conventional spermicide.

Other household chemicals

Other household chemicals that aren’t safe are spermicides.

These chemicals should only be used as directed and should never be used internally or as spermicides:

  • vinegar
  • hand soap
  • body wash
  • bleach and disinfectants

You can also find out how to make your own hand sanitizer at home.

How to use conventional spermicides

According to Planned Parenthood, spermicide is most effective when used with another form of birth control.

To use spermicide effectively:

  • Insert the spermicide formula deep into the vagina according to the directions on the package.
  • You may need to insert the formula 10 to 15 minutes before sexual intercourse for it to be effective. Check the directions on the package.
  • Have sexual intercourse within 1 hour of inserting the spermicide. Otherwise, it may lose effectiveness.
  • Consider also using a condom to maximize the effectiveness of the spermicide.

Be aware that spermicide does not prevent sexually transmitted infections (STIs). It’s important to use additional barrier methods, such as condoms, to protect against STIs.

Frequent use of spermicides may also increase vaginal irritation. This may increase the risk of contracting STIs.

Conclusion

Speak with a healthcare provider about how to use spermicide safely and the most effective birth control methods for you.  All hand sanitizers kill sperm and should not be used in your vagina for any reason.

If you use hand sanitizer make sure you wash your hands with clean water and soap before touching your vagina.

Because hand sanitizer will not only kill sperm but will also destroy the normal pH of your vagina and cause irritation which will give way for harmful bacteria to grow in your vagina.
