No one really knows exactly why some pregnant women get morning sickness. But Professor Gordon Gallup, a psychologist at SUNY-Albany believes he’s got the cure: oral sex. And yes, I’m actually serious about this.

Gallup and a grad student of his presented their findings at the 2012 meeting of the Northeastern Evolutionary Psychology Society. Gallup’s theory is that morning sickness is essentially the body’s way of protecting itself against foreign substances–in this case sperm and the fetus that shares some of the sperm’s genetic material.

His solution? Regularly ingesting sperm before getting pregnant will help women build up a tolerance and will reduce or eliminate morning sickness.The key is that the pre-pregnancy sperm and the sperm that cause the pregnancy has to come from the same source.

As crazy as this sounds, Gallup may be onto something. There is some evidence that oral sex (as long as there’s some sperm ingested) during pregnancy may reduce a woman’s risk of pre-eclampsia (a kind of high blood pressure) and may even have antidepressant qualities.

Of course, the best way to test this theory is to try it at home….
