Let me get this straight. When someone enters your form, on a male record, they see an unchecked box that says "male", and nothing that says "female". Such a form would look to me like it means "not male", so if I wanted the record to be male I would check the box. Then it suddenly says "female", and I would then scratch my head and un-check it. Then it will say "male" again. That's what I think would probably happen.

I maintain that a pair of option buttons are more appropriate for displaying a field storing two equivalent logical conditions. We don't want a control like a checkbox which seems to say "female" or "not female". I have never seen a paper form that looks like that. You should see a clear choice of "male" and "female".
