A Japanese scientist won the spoof Ig Nobel medicine prize in Cambridge, Massachusetts, on Thursday for a study that revealed kissing could reduce allergic reactions in humans.

"I wish that people will understand the new effect of kissing and I also hope that kissing will bring not only love but also attenuation of allergic reaction," Hajime Kimata, who could not attend the 25th annual event, said in a videotaped acceptance speech. "I am honored to be awarded the Ig Nobel Prize and I appreciate it very much."

Kimata received the prize jointly with three Slovakian scientists who also studied the "medical effects of kissing." The Slovakian group looked at how long male DNA stays in a woman's mouth after "intense kissing."
