a dutch reality-tv show tried this already. (Expeditie Robinson?) they put 2 groups of people on 2 small tropical islands, where they have to survive and compete in challenges against the other group
one time they tried forming the groups based on gender. even from the start it went so fucking bad on the womens island they had to intervene, their experience was miserable, spending their time sunbathing and fighting eachother about no work getting done and nobody gathering food. so they ended up mixing the groups up not even halfway through the season
another time they tried women only, 16 of them on 1 island. some had to be removed for medical reasons and they ended bringing in men to replace them. i think they stopped experimenting with division based on gender after those experiences
needless to say, the male groups were having the time of their life before they were split up to go and bail the females out of trouble
