I was able to get some - apparently mine came from one of the first collections after his accident. Got 30 freezable embryos using three straws on one flush. I understand its few & far between.
Genex collected him, and they have some of the best semen out there. I have pocket thawed their semen and my conception rate is not changed.
I am lucky enough to have purchased the LnL semen from Genex, and have 11 straws left....
