No, if hairs haven't popped by now...it could be either male or female. However, I find that males usually show first. I don't understand how a plant that size isn't showing preflowers somewhere...have you sexed a plant before? Do you know what you are looking for?
Maybe try and get a bit clearer pics from closer to the top of the plant?
Plant looks great, by the way--big and bushy and green.
