(See chapter 3) In line with what we have said above, we agree that there needs to be ongoing and extensive collection of data so as to better assess the outcomes, and especially the risks, associated with the use of eggs that have previously been frozen. It is beyond the scope of our expertise to comment more specifically on either the nature or the manner of collection of this information. Question 3: Has ACART identified all the ethical issues relevant to the use of frozen eggs in fertility treatment? Do any of these issues affect ACART's proposed advice that the use of frozen eggs should be allowed in fertility treatment? If so, how? (See chapter 5 for a discussion of the ethical issues, and chapter 6 for the proposed advice.) The posthumous use of frozen eggs raises similar ethical issues to the posthumous use of frozen sperm.
