- Is sperm donation right or wrong?

You are absolutely right! Everyone has THE NEED to know who they belong to.

I think it was last year that the girl who was the FIRST EVER "test tube" baby turned 25. She definitely had issues on not knowing her past.

How terrible.

there was bill in US too but not successful, many European countries including UK revoked such ban by law and children can find out the identity of the bio father /mother once they reach 18 years old of age.

Then in that case, many donors will back up!

I mean who wants trouble after 18 years when you have your own house full with 5 kids!
