I will chime in and say I don't approve of the OP's actions either. No offense to him I just don't like this on many levels. If the OP is dying and needs something from the donor that is one thing. That can be accomplished while keeping the donors identity private however.
Has the OP even considered the donor may not want his info given out and he does not want to meet the OP? Has the OP considered maybe the donor is married now and if the wife found out it would be a problem for the donor? Has the OP considered anything other than what he wants?
This isn't a dead beat dad. This is a donor who deserves to remain anonymous. Most donors do not wish to meet the kids. Kind of the point. They donate anonymously to help those who can't conceive on their own or maybe it is for money. Either way I am pretty sure they do it with the expectation they are not contacted by the kid. If the OP insists on pursuing this I would ask at the fertility clinic if the donor requested to remain anonymous. If so drop this ASAP.
JMHO.
Did you read my original post? This was done back in the late '70s when there was little to no regulation and oversight of fertility treatment procedures/AI. The doctor has been dead for 4 years and long retired before that. His practice is closed. There is no record of the donor (that I know of). Again, I'll repeat, all I know is what I was told by my Mom, and she was repeating what the doc told her, which is that the donor was a resident physician at a hospital in Memphis at the time.
As far as whether or not he would like to be contacted, a lot changes in 37 years. I can see a young guy in his mid-20s donating sperm in sort of an amused way, thinking it would be kinda neat. Maybe it's some sort of ego trip for him. There's no telling.
Personally, I'm very curious, and, if I'd donated sperm, curiosity would get the best of me eventually. I'd want to know if there had been any successful pregnancies achieved through my donations.
I'd like to think he's as curious as I am. Furthermore, I have to think that we share some traits and interests, and that we could share a relationship, based on common intellectual interests and recreational interests.
I have to think - he's gotta be wondering what ever came of those donations.
The fertility doc had a son who is now also in practice as an OB/GYN. That will probably be one of my next steps - to contact him. Also, to try to obtain a yearbook or other records of University of Tennessee College of Medicine students and residents at that time.
