Part of the process of in vitro fertilization involves the transfer of embryos conceived in a "test tube" to the woman's womb. Following embryo transfer, she may be confined to bed rest for 1 hour or 24 hours -- but with either one the pregnancy rate seems to be similar, new research shows.

Gabe: Obviously there's a lot of you guys out there. A few million easy. I try very hard not to use the site for evil but occasionally I can't help it. This is one of those times. On June 29th the iPhone drops. I know I know it's only 2G but let's all just agree that I'm a gadget whore and move on. I've spoken to a couple people at Cingular stores and what I'm hearing is that I have a better chance of giving birth this month than of getting my hands on one of these phones. So I'm turning to you. I'm not asking you to kill or riot (yet). I just need to know what I should do if I really want to buy one of these on the 29th. I could also use some help obtaining a Beautifly. I understand I need a Wurmple to evolve into a Silcoon. However that takes place at level 7 from what I understand and I can't seem to find a Wurmple lower than 10 or 11. I thought I might need to breed a baby Wurmple but then I still run the risk of it evolving into a Cascoon rather than a Silcoon. Am I on the right track with the breeding idea and if so is there anything I can do to ensure I get a Silcoon? Also I am a huge pussy. -Gabe out
