Don't know who's doing your invitro work, but the one I am familiar with, prefers thawing conventional semen and then sorting (sexing) it.  They have a better success rate than using frozen sexed semen for fertilization.  I didn't ask, but I assume there is less total stress on the wigglers doing it that way rather than using frozen sexed semen.  Your IVF facility may not have the sorting capability. I would ask.

I know that there is sexed hard whiskey semen but can't remember if her is a purebred.
