Yes, saliva can be bad for sperm.
Saliva's negative impact on sperm motility and progression has been indicated in studies. While low concentrations might not cause a significant issue, higher concentrations can significantly decrease sperm's ability to move effectively, hindering its chances of fertilizing an egg.
Here's a breakdown of why saliva is detrimental to sperm:
-
Enzymes and pH: Saliva contains enzymes and has a pH that is not optimal for sperm survival.
-
Reduced Motility: Studies show that exposure to saliva can reduce sperm motility, which is crucial for successful fertilization.
Therefore, saliva is generally discouraged as a vaginal lubricant, especially for couples experiencing infertility. Alternative lubricants specifically designed to be sperm-friendly are recommended in such cases.
