Yes, I'd be happy to expand on that. That is a specific reference with respect to this issue that we keep returning to, whether or not you should be approaching women who are creating embryos for their reproductive purposes and encouraging them to donate them to research when it's in their best interest that they be frozen for their own reproductive use.
I would agree, however, with what Dr. Buckett made clear a minute ago, which is that there are some embryos that are not suitable for transfer. If it were the case that they were not suitable for transfer, they're presumably not suitable for freezing in the context of pursuing a reproductive project, and I would allow that it would then make sense that they would be available or eligible for research.
But that is not in fact the constraint that is put on the fresh embryos; therefore, in theory, healthy fresh embryos that could otherwise be used for reproductive purposes would be available for research purposes. And that's the part later on where I talk about how this is contrary to women's interest. If they truly want to get pregnant, it's better for them to freeze their embryos. If they don't want to have to pay to be hyperstimulated again, it's better for them to freeze their embryos. If they don't want to take the risks of hyperstimulation again, it's better for them to freeze their embryos.
All in all, if you're deeply committed as a clinician to doing what's best for your patient, you ought not to be approaching them and saying, “By the way, there are some other options here. Instead of freezing them for yourself, would you like to give them up for research?” I'm saying that's something that ought not to happen, and I can happily report that in most clinics it does not happen.
