Histologic findings in rat testicular tissue utilizing different fixatives.

	Average pathologic score
	Formalin	Bouin solution
Nuclear membrane detail	2	1.3
Nuclear granularity	1.9	1.4
Cytoplasmic granularity	1.4	1.5
Cytoplasmic membrane detail	1	1
Basement membrane detail	2	2
Sloughing of cells into lumens	1.6	1.4

For nuclear membrane detail, nuclear granularity, cytoplasmic granularity, cytoplasmic detail, and basement membrane detail 2 = highest quality. For sloughing of cells 3 = most sloughing.
