Abstract

This experiment tested whether in utero and lactational exposure to 4-nonylphenol (NP) alters mammary gland differentiation in the female offspring rat. Pregnant Sprague Dawley rats were administered NP (l0, 100 mg/kg), atrazine (l00 mg/kg), pesticide demonstrating antiestrogenic activity in mammary gland development, or vehicle (0.5% methyl cellulose) by oral gavage from gestation day 15-19.(omitted)
