Looking precisely in relation to indoor features of the station, I don't think there are gents only toilets here.

Without a level tag it's difficult to be sure though. So either these toilets are right here, and they need a level tag, or maybe...
I think they might have been put here roughly in the middle of the station a while ago, perhaps representing these ones which I've placed at least a bit more precisely: http://www.openstreetmap.org/node/5262929022#map=19/51.53126/-0.12456 ...maybe
