This website from the UK is quite informative
http://www.ivf-infertility.com/ivf/standard/regulations.phpI found a few more site about regulating. Most from individual states.
Several from forced birth organizations, which is irony personified.
I hadn't realized, I suppose, that in the US the procedure is so privatized. Anyway, I guess this throws the whole discussion into do we want Federal regulations of IVF? Where is the evidenced based practice on what is most effective? How many embryos per attempts, how many attempts? Do Lesbians qualify? Do single mothers? What is the age cut off?
It would be an interesting piece of legislation indeed.
