Fifty quid two or three times a week adds up (in us banks they are expected to 'donate' this often).
The men are inadequately counselled. Also, they may well feel differently when they meet the children.
The donor who said the children would not be brothers or sisters to his social and biological children was also not thinking about what his own social and biological children would make of the whole thing.
And of course, the donor conceived offspring may well feel very differently about it all. For them, the biological connection may well be relevant (and of course it is often very relevant, otherwise why would women fight so hard to conceive with their own eggs before using donor eggs?).
I thought the film's director managed the issue of anonymity very well. she made it clear that their are multiple offspring from danish sperm and that this puts a very different slant on the idea of non-anonymous.
HOWEVER, I believe the director was wrong in saying that ID release donors commit to meeting the children at least once. In the UK and the US ID release donors commit only to having their ID released, they do not commit to any sort of contact.
I thought the director very tactfully tackled the difficulties of using anonymous donor (as opposed to id release) by having the well adjusted child of a single mother and anonymous donor talk about the impact this had had on her sense of identity and self.
I felt terrible for Gemma. I so wanted her to be pregnant. I hope she adopts or conceives with donor eggs. I also hope she finds support.
