Does saliva kill sperm? What is the function of saliva?

Everyone has different habits and preferences, which leads to different sexual preferences. Some people like to lick their partner's genitals with their tongue during sex, allowing the saliva to act as a lubricant. But those who do this often may find that they want children but have a hard time getting their wife pregnant. So, does saliva kill sperm? Let's first look at the role of saliva:

1. First of all, we all know that the function of saliva is to help us moisten food. Just imagine if there were no saliva, it would be so difficult to swallow our food, especially some dry food, such as sesame cakes, flatbreads, pancakes, etc. Moreover, if we are not careful, it may cut our mouth. Saliva moistens and dissolves food, making it easier for us to swallow.

2. Another function we know is that saliva contains salivary amylase, which can hydrolyze starch and enable initial digestion. The food we usually eat, such as pasta such as bread, buns, and sesame cakes, mainly contains starch. Although the stomach is the "main force" in digesting these things, the amylase contained in our saliva can make it digested initially, hydrolyzing starch into maltose, making it easier for our stomach to digest and reduce the burden on the stomach!

3. If there are toxic substances in our mouths, they can be diluted and neutralized because saliva contains some bactericidal substances. Lysozyme and immunoglobulin have bactericidal and antiviral effects. Therefore, saliva always silently plays the role of a "bodyguard".

4. Saliva will actually affect the quality of sperm. Saliva will have a harmful effect on the vitality and motility of sperm. If couples want to conceive a baby, it is best not to use saliva as a lubricant.

Saliva has many functions, such as moistening food, aiding digestion, killing bacteria, etc. However, saliva can also affect the vitality of sperm. If saliva is often used as a lubricant between couples, it may affect the quality and vitality of sperm, thereby affecting women's conception. Therefore, if you are preparing for pregnancy, it is best not to adopt this method of making love.
