title: Inactivity of styrene in the mouse sperm morphology test.
abstract: Male F1-mice (C3H/He X C57B1/6J) were exposed to styrene by inhalation (150 and 300 ppm; 6 h per day; 5 days) or intraperitoneally (175, 350 and 700 mg/kg per day, 5 days). No statistically significant increase was detected in the frequency of abnormal sperm heads 3 weeks (spermatids exposed) or 5 weeks (late spermatogonia/early spermatocytes exposed) after the beginning of the exposures.
