Abstract

Exposure of males to some genotoxic chemicals causes DNA damage in spermatozoa resulting in embryotoxicity and developmental defects in their offspring. This study demonstrates that cisplatin-DNA adducts could be measured in spermatozoa following treatment with the antineoplastic drug, cisplatin. The formation of spermatozoa cisplatin-DNA adducts showed dose and time-dependent increases both in vitro, and in vivo up to 168 h (7 days) after dosing. Treatment of rats with 10 mg cisplatin/kg resulted in spermatozoa Pt-GG adduct levels of approximately 1.0 fmol/μg DNA. When cisplatin-treated male rats were bred to untreated females 6-24 h after cisplatin administration, no adverse developmental effects or decreases in body weight were seen in the offspring although there was a trend towards increased early embryo mortality.
