what exactly do they look for in a scan for a boy? It seems that lots of people are saying they look for a little appendage but I would havethought that the testicles would have been more obvious. At my 20 wk scan i was told they couldn't see a willy but thought could see testicles. i would have thought this was what to look for anyway and mustbe easier to see than an appendage which could possibly be the cord! Any ideas anyone?
