Headline: Swallowing Semen May Actually Increase Your Chances Of Having A Baby Content: The researchers acknowledge that their sample group is small, and did not provide evidence that swallowing semen actually leads to a lower miscarriage rate.
Within a tiny sample group, yeah. And now you'll probably hear people parrot this like it's a fact. Take a thousand people and the result might be quite different. Who knows.
It's also more likely for a women to get pregnant after multiple exposures to semen vaginally. After a while her body no longer sees the sperm as a threat. It knows it's her mate. I could see oral sex having the same logic.
Well nothing has been proven by this study, due to its tiny size, so I guess what you're saying makes no sense.
