i heard about the male-female ratio sometime ago from an administrator.
Female students tend to get higher grades and therefore MORE get accepted into medicine. The only problem is that a LOT of them tend to back out because of various reasons (pregnancy, marriage, moving with husband to another country, has to take care of children etc...) and therefore to minimize the problem (waste of educating student dropping out) they decided to make sure to get more male students to balance the effect. The easiest way was to generate equal numbers 50% male and 50% female. This was in the past...
