Are you pregnant and suffering with morning sickness? Great news! Swallowing your husband’s semen will cure your nausea! Well, maybe… but better safe than sorry, I always say.

So what does Gallup say is the real culprit behind nausea and vomiting in early pregnancy? Semen. More specifically, unfamiliar semen. To understand where he’s coming from, we need to think back to the maternal immune system’s response to the fetus. Because half of the DNA the fetus is carrying comes from the father, the mother’s body may initially treat the organism as foreign tissue or an infection. This response, Gallup says, triggers an immune reaction that is commonly experienced as nausea, vomiting, and malaise (aka morning sickness). The best cure for this type of sickness, says Gallup, is, strangely enough, the same thing as its cause. The more exposure a woman has to her partner’s semen—that is to say, the more often she’s inseminated prior to conception and during the early stages of the pregnancy—the more tolerance her body develops to his genetic material. This tolerance generalizes to a tolerance for the fetus and leads to successful maternal immunosuppression—and subsequently allows her to feel less like an infected zombie with serious stomach troubles.

Swallowing your husband’s semen also appears to reduce the risk of preeclampsia.

Normal pregnancy is thought to be associated with a state of tolerance to the foreign antigens of the fetus, whereas in preeclamptic women this immunological tolerance might be hampered. The present study shows that oral sex and swallowing sperm is correlated with a diminished occurrence of preeclampsia which fits in the existing idea that a paternal factor is involved in the occurrence of preeclampsia.

So, dear readers: go do some research and report back.
