Smithy,

I think the reason that they limit the donors to age 45 is so that there is more likelyhood of an 18 year old being able to be in contact with their donor father. I know that our donor 'just' made the limit at age 44.

Beema,

The donor is limited to donating to 10 families. You're right - it was a big deal when there were anonymous donors that were not tracked. Geraldine Hewitt is a child created from donor sperm, and in her research to find her father she found one man donated over a period of nine years to six different Sydney clinics — he made 318 donations — and these clinics don't have records for how many resulting births."

I think that this is why they don't want to go down the paying for sperm track - I always see that episode of the Simpsons where Barney has donated to support his alcoholism, and there are 20 kids in the same suburb all with his familiar burp.

To me meeting an unknown donor would not be all that dissimilar to an adoptee meeting with their biological mother or father. Most children would be interested in finding out about their biological family.

What I found interesting in the whole segment was that a) it really showed why men were very reluctant to donate, and b) the lengths the clinics have to go to now to try to attract donors. And I really don't know how the clinics will overcome that reluctance.
