Blastomycosis and dog semen

Blastomycosis and Semen

I got a call from a gentleman who owns a male intact German Shorthair that was diagnosed with blastomycosis. They collected and froze semen before starting treatment and the bitch to whom the dog is to be bred is now is season. The owner wants to know if blasto is transmissible through that semen. I know dogs with blasto shed tons of organisms into urine but cannot find any info about shedding into semen, likelihood of blasto surviving the freeze/thaw process, or likelihood of infection of the female via introduction of organisms in her uterus. Any suggestions are much appreciated!
