With the conversion of the last men-only colleges into mixed colleges in the 1970s and '80s, there were inevitably questions about whether any of the remaining women-only colleges would also change to mixed colleges. The issue again became prominent as women only colleges throughout the rest of the country began admitting men and following the 2007 announcement that Oxford University's last remaining women-only college, St Hilda's, would admit men, Cambridge is the only university in the United Kingdom where colleges have admissions policies that discriminate on the basis of gender.
