Marlena Valles and Rebecca Meredith claim they were met with boos and calls of "shame" as they spoke in favour of female equality during the Glasgow University Union's (GUU) annual Ancients competition.
The women claimed they were also met with comments about their appearance and choice of outfit.
Ms Meredith, from Kilmacolm, Inverclyde, who is studying at Cambridge, described misogynist and intimidating behaviour from a small number of men in the chamber.
The Cambridge Union Society yesterday voted to revoke reciprocal membership with the GUU
GUU president David Lockhart, who chaired the final, issued an apology to Ms Valles and Ms Meredith.
Action, ranging from fines to suspension from the union, may also be taken against the students responsible.
