N1 - Funding Information:
I am grateful for the excellent technical assistance of Darlene Bowling and Kathy Spring in the preparation of histological specimens. Most of the examples used in this review were obtained through studies funded by the U.S. Geological Survey’s Biomonitoring of Environmental Status and Trends (BEST), National Water Quality Assessment (NAWQA) and Chesapeake Bay programs and we are grateful for the financial support and collaborative opportunities these programs provide. The yellow perch examples were from of a study funded by the Wisconsin Department of Natural Resources and done in collaboration with Candy Schrank.

N2 - Histology offers a powerful tool in the study of reproductive health of fishes. It is routinely used for sex verification, identifying stage of development, documenting presence of intersex, tumors, parasites and other abnormalities and quantifying atresia. It can also be used for more subtle changes such as thickness of the vitelline envelope at various stages, yolk appearance, necrosis of sperm, and Sertoli cell proliferation. Gonadal histology, in conjunction with hormone and vitellogenin measurements, morphological and fecundity studies, can provide insights into the effects of various environmental stressors on reproductive health. However, much research, both field and laboratory, is needed to understand cause and effect for observed changes and to understand the meaning of many of the histological observations made in field studies, in terms of reproductive success of fish populations.
