It is not the sperm that is retested...it is the donors blood. But they can't use the sperm until the donors blood is confirmed to be clear of lurgies hence the six month wait because of the delay in HIV showing up in the blood stream.

I am almost certain that the six month wait does not apply to overseas samples as long as the donor overseas has already served the six month quarantine initially and had all the follow up blood tests. And if you use the same donor more than once you wouldn't have to do another six month wait if you get what I mean.

And the new law regarding being contacted at age 18 is federal...you cannot donate either eggs or sperm in this country anymore unless you sign that you are willing to be contacted by any offspring when they turn 18 (if they choose to seek you out).

Hope that helps answers some questions...
