I have had, thank God, no fertility problems to date, but would not have IVF for twins, despite the fact I would love to have twins.

Why? Because it's a dangerous procedure, what with OHSS and things like that which can occur. Because, so far, I haven't needed it. Because I know if I did need it and was sat next to someone with no problems who just wanted twins for a fashion statement I'd be hurt and upset.

Because once it becomes the norm for healthy women to have IVF to get what they want wrt number of children, maybe it will become the norm for people to have IVF for screening for genetic illness. Then "undesirable" genes, such as those for specific looks (I'd hate to have a daughter who looked like me but not to the extent I'd do genetic screening... but if it were the norm would I still think like that? I'd hope so but how do I know?)

I just think it can be a slippery slope. IVF shouldn't be denied to people, but I believe it should be VERY restricted and made difficult if you don't have fertility problems - as I believe it currently is.
