if there aren't too many balls you can try to remove them
there are 2 different hermies, one is OK hermie that has only a few balls, and then there are the BAD hermies, which have pollen sacks all over - those are better to get rid of
if the OK hermies pollinate female plants or self polinate you will have feminized seeds, if a BAD hermie pollinates - you have approx 50/50 chance for a hermie or girl, and very very minor chance to get a male plant
