Evaluation of Propineb, a dithiocarbamate pesticide, in the mouse-sperm morphology assay.

Propineb, a dithiocarbamate fungicide, was studied by using the sperm morphology assay in (C57BL6 male X C3H female) F1 mice. At all dose levels, no statistically significant increase in the percentage of sperm abnormalities was observed. Methyl methanesulfonate (MMS) and 2-acetylaminofluorene (2-AAF), which were tested as positive controls, induced a dose-effect-related increase in teratospermia.
