Read the info for donors on Fertility Scotland. Eggs can be kept for 55 years. A child conceived could potentially sue the donor if you've had an undeclared medical condition. Risks are stated.
'you will need to sign legally binding consent for the storage and use of your eggs. By law, donor eggs can be stored up to 55 years'
'A donor-conceived person born with an abnormality could successfully sue for
damages if it is proven that you withheld relevant facts about your personal and/or family’s medical history when you donated eggs.'
'Donors cannot be given any information that could potentially identify the children conceived from their donation'
'At 18 years old (or 16 if intending to marry), a donor-conceived person can obtain their donor’s identifying information'
'In some very rare cases, women develop ovarian hyperstimulation syndrome'
Stats would be helpful for the OHSS risk, I'd think.
