Well, in regards to #1, I can tell you that I have a tilted uterus and I have two sons. I believe a friend of mine also has a tilted uterus and her only child is a boy, as well.
Regarding #2, hopefully some others can help you with that. If you don't get any answers here, I would recommend you do a search for user nuthinbutpink and the information in her signature (plus her avatar image) will point you in the right direction. When it was working, InGender was an awesome site, but due to all the technical difficulties, many folks have felt the need to move to NBP's site ... which is very active and monkey-free. :)
