Well this is the first time I've ever heard this myth. There are women out there that believe that the salt from McDonald's french fries can make you more fertile. So this means that after these women are having sex with their partner they're eating fries so they can get pregnant? Is this serious?
Some other myths/techniques that women use according to a recent survey are -
58% of moms have said they have put their legs in the air and pretended to ride a bike
37% eat dark chocolate every day
37% drink pineapple juice.
