I understand that seeds from a hermie will be female, but I have no expertise about that.
However, I can only grow once a year, and if it was me I would probably snip off the male bits pronto, and check every day for more and snip all found off and grow it out, or do it more properly like Lerugged mentioned. In that case I'd grow it out, after all, what else I am I going to do in the garden department while waiting for Spring to come around again, SFA?
If you have got nothing else on the go being held up, and you want to get some female seeds that hopefully won't hermie under normal/good growing conditions (no light leaks etc), then don't bother removing any male bits but search the buds for seeds when harvesting/jarring, and I guess the seeds would be good (& female).
But, I don't imagine that hermie seeds are too good to have if they are a product of a plant that hermied for no apparent reason, i.e. if it is genetically prone to hermie it probably is not going to be suitable for seeds. But as I said I am no expert and it isn't even worth 2 cents.
