Stewards and safety officers are being briefed on how to spot - and tackle - sexist abuse in football stadiums, reports BBC Sport. Women in Football, which represents more than 1,200 women, has contacted all 92 Premier and Football League clubs about the issue.
Footage obtained by the BBC shows Chelsea's female medic Dr Eva Carneiro and assistant referee Helen Byrne suffering taunts at games.
The Football Association has called for fans to report sexist abuse.
A WIF spokesperson added: "This is the first time that clubs have specifically been asked to focus on the issue of sexist abuse."
WIF's letter to clubs explains what should be considered sexist chanting and tells them that any incidents should be dealt with as "they would do with racism".
It asks clubs to brief stewards on how they "would be expected to respond to any such incidents".
It added: "This sends out a message that sexism is unacceptable and that we want the game to remain safe for everyone."
The month-long campaign will focus on social media and will aim to persuade more fans to report sexist discrimination.
WIF are asking people to tweet the hashtags #ShameOnTheGame to highlight abuse and discrimination and #SheBelongs to celebrate women.
