Some people swear that mosquitoes bite women more than men. Dr. Oz was asked whether there was any truth to that, and he said it wasn't likely.
Cues such as body temperature, carbon dioxide in the breath and certain skin chemicals such as lactic acid all help mosquitoes orient themselves and find their next meal, he said.
Since men are larger than women, they are bitten more, but may not be as sensitive to the bites. Pregnant women exhale more carbon dioxide and get bitten more than other women.
Many people believe the unproven claims that B vitamins, such as those consumed through meat, may mask smell. Men tend to eat more meat, consequently, they are thought to be less attractive to mosquitoes.
