Just know that any female can put out pollen due to stress, or whatever reason, but a true genetic male will never put out pistils (female hairs). Any plant that is pollinated from a female/hermaphrodite will always be either female, or hermaphrodite, but no true males can ever become of them.
In my experience if you are getting hermies like this you are likely to have problems with the next generation. Male parts can pop up even late in the game after buds have formed. I personally prefer strains with a good strong male backbone, and never any flukey females for that reason. I also concentrate on the males more than the females when choosing candidates for propagating a strain.
In short, hermies can be a pain in the ass.
