Known Donor Sperm Testing

[Melona]

My partner and I are in the early stages of our RIVF fertility journey, currently based in London. We're using a known sperm donor, who's in New York. We’re trying to find an NYC fertility centre with international accreditation, to do the sperm analysis, for our London clinic to consider the results valid before we go ahead with the next steps. Does anyone know of an ISO-accredited clinic in New York? Or maybe even LA?

PS. He can't fly to London in the next six months, that's why we're reliant on getting the first half of his fertility testing done in the US.
