Professor Deirdre Madden:

There would be a limit on the number of children who could be born using one donor, which is important, particularly in a country the size of ours. The limit would be imposed by the regulator. Whether the number would be, say, three or five would depend on the number who would be expected to use the service, the geographical spread and so on. There should be the possibility that children born through donor-conception, at whatever age was considered appropriate under the legislation, whether it be childhood or adulthood - I do not have a particular view on it - would be able, through the registration system, to have contact with genetic siblings if, of course, the other siblings were in favour of such contact.

Was there another question?
