A New York-based psychologist has a solution for pregnant women with morning sickness: Swallow semen.

Dr. Gordon Gallup’s theory is compared with the “hair of the dog” concept, which claims that the best cure for a hangover in the morning is drinking more alcohol, according to video from newsfixnow.com

Gallup says the woman’s urge to vomit is the result of a foreign substance coming into her body. So, if the woman has more of what made her sick (semen), it should work like that drink in the morning, the video says.

There is no scientific proof of that theory, however.
