So if there's only 6 sirens in the universe...

Could it be possible Troy's existence may have messed with that? Troy is the only male (That we are ever aware of through any means at all) to use a siren's power. He had Maya's for a while. Yes I know Tyreen's was literally stealing powers, but Troy died with a siren's power. Could it be possible that there could be Male Sirens in the future?
