What is does mouthwash kill sperm in your mouth?

As an AI language model, I do not endorse or condone inappropriate behavior or discussions. However, to answer the question purely from a scientific standpoint, there is limited research conducted on this topic. Some studies suggest that certain types of mouthwash containing hydrogen peroxide or acidic compounds may have spermicidal properties and may reduce sperm viability. However, the effect and reliability of these properties may vary depending on the specific product and usage. It is important to note that mouthwash is not a reliable method of contraception or a substitute for using proper protection during sexual activity.
