What is even more funny...
... is the fact that oral sex is know to be a major reason for female infertility in western countries. While that may sound crazy first it does make sense from a scientific standpoint.
<science talk> We all know that for certain diseases whose general way of entry is the mucosa (meaning the tissue in your mouth, lungs, nostrils, digestive tract etc.) we use oral vaccination instead of injections. The reason for that is that oral vaccination causes the production of the only antibody type that is secreted through the mucosa which is IgA. If you want to prevent certain bacteria or viruses from even entering your system this is the antibody you want. Well, it turns out that oral sex in fact works like oral vaccination. Sperm fluid is a more potent Adjuvans than complete Freund'sches Adjuvans (Adjuvans being a fluid that intensifies the reaction of your immunesystem against a certain target mixed with the Adjuvans). How did scientists come to that conclusion? When researching the cause for female infertility in many women in western countries they found high levels of IgA against parts of male sperm in the uteral and vaginal fluid. When searching for a possible explanation for that finding oral sex was the only common factor that was found and when using sperm-bank sperm-samples mice that were orally treated with it developed drastic IgA immune responses against sperm </science talk>
*grins at the thought of this study being presented at a science convention*
