I'm not arguing with you yeartolate, but this is an issue which is close to my heart so if it's going to be discussed it I'd like to see that it's done accurately. These are my opinions and experiences.

most of the people I know who have undergone IVF have had to clearly sign papers about what their options were.
In my case, we were not contractually held to our original choices. We still were required later on to make decisons about what we wanted to do with the extra embryos. That, to me, is a good thing. When you begin the IVF process it would be difficult to see into the future and know exactly what you want to do years later, not knowing the cirucumstances of your individual experiences to come. Clinics must recognize this, because six years after our embryos were originally frozen, we felt differently than we did at the outset, and also learned there were other options available to us that weren't listed (or even available originally).

Most (that I know) have made an active decision NOT to have others adopt their frozen embryos. It was more than disconcerting to them to have full sisters and brothers running around. I totally support a family's willingness to adopt out their embryos, but I can understand the conflict.
I understand the conflict, too. I regularly talk to couples all over the country who are thinking about it, and have been interviewed by major publications about this issue. It isn't easy, and obviously not for everyone. But IMO it's less that people "don't want brothers and sisters running around" (which sounds slightly offensive and uninformed, BTW) than it is that
they aren't even aware embryo adoption is an option. Most of the women I talk to would like to give their embryos a chance to be born, but definitely are conflicted about it, in part because the options are unclear, but also because they have trouble with the thought of another family raising "their" child. These are the realities based on what I have seen.
My own clinic only offered three options: destroy, donate to (stem cell) research, or anonymous adoption, the latter of which was not something I was interested in either (ours was private, but again, I found that option on my own, not through our clinic).
This is not directed at anyone, but I believe that until you have embryos that are your own, I don't think you can say with any degree of certainty what you'd do or feel under the same circumstances. That was the case for me as well.

If a clinic is not educating the woman with leftover embryos on their disposition, I think they are falling short of thier duty.
I agree, that was my point.

Most women that I know that have gone through IVF have totally educated themselves prior to commitment . They seemed aware of the issues if they had a sucessful pregnancy on the first cycle.
I don't know how many couples you know, but I've met dozens in the 11 years I've been immersed in the world of IVF, and my experience is just the opposite. In fact, there is very little, if any, education or support. And my clinic was one of the better ones.

Hopefully, that may have changed for the better in the past few years.
I've also had discussions about stem cell research (which I am for, on embryos dedicated to research) with many people and a good number of them readily admit they don't know exactly what the issues are and/or can't hold an intelligent discussion about it.
