I do not know, but do know a lady in our breed who is a ministry vet, and lives in Leicestershire, so she may know.
I would have thought if your vet doewsn't offer the service themselves, the least they could do would be to find out for you.
Can'#t see what the problem is though, it only needs them to take a smaple and look under a Microscope, for a basic motility test.
