@patrick80 I've not read all the replies here. It's rare for the adoption boards to have 9 pages on any thread.
We have a birth daughter, and had treatment with donor eggs and had stored embryos for a frozen cycle. When the last frozen cycle failed we had a break of a few months and started the adoptoon. Our adopted son has been with us for over 5 years.
In my humble opinion it is utterly wrong for the agency to demand you destroy your embryos.
What they need, IMHO, is an assurance from you that you are fully committed to adoption and have no currant plans to use these embryos.
I assume they are stored for a limited time which you can choose to extend if you wish (I believe) and some will make decisions at a set time to end the storage.
People going through adoption do need to assure the social worker that they are fully committed to being parents by adoption and hopefully you can do this without being pushed into something you regret.
The position of having to make a choice about these embryos seems utterly unfair to me.
I'm really sorry you told them because it is none of their business!
After years of treatment I knew I could not realistically get pregnant again but if they had asked us to use contraception I would have done so. (We were not asked.)
But those embryos are not something you should have to make a decision on to satisfy a social workeR. If it limits your chances in adopting I'd say decide what you both want to do and stick to it.
Good luck.
