Yea. Im confused as well. lol. For the longest time i thought it was just the stress factor. But maybe it is a bit of both because in order for a plant to detect if its going to die out it would have to realize its under stress and it needs to do something. But genetics tells it that its a certain sex, so maybe the plant figures, like you said sawleaf, that it needs to produce the male sex organs in order to attempt to save itself. So maybe a male plant arises from the seed being under stress and it becomes a full male in order to attempt to save its self? Who knows...Regaurdless you should always treat yur plants well. Its going to be a 50/50 shot, so good luck..lol. Thats about all u can say i guess..
