"The members of this list publicly pledge not to participate as speakers in any academic event or round table of more than two speakers where there is not at least one woman as an expert," the manifesto read.
More than 80 other experts have asked to be included on the list, according to the Twitter account of the manifesto, which is presented as a "collective initiative".
The manifesto comes as Spain is experiencing a revival of the feminist movement, which is demanding more be done to ensure real equality between men and women.
Spanish women staged an unprecedented strike in defence of their rights on International Woman?s Day in March and held massive street demonstrations that day in the whole country.
