We fix canine testes in bouin's solution for 24 hours then gross them in and
put back into bouin's for another 24 hours before processing. If we don't
process right away then the testes are placed in 70% alcohol for storage.
Bouins seems to fix the microscoptic detail better than 10% formalin or
alcoholic formalin according to our pathologists.
