Phenylethanol was given at different levels (432, 43, or 4.3 mg/kg) by gavage to pregnant Long‐Evans rats during the “critical period” of organogenesis. Examination of offspring revealed adverse reproductive and teratogenic effects in a dose‐related manner. Intrauterine growth retardation occurred at levels of 432 and 4.3 mg/kg. Embryolethality was 18% at 43 mg/kg and 10% at 4.3 mg/kg. Malformations occurred in the following sequence: 100% at 432 mg/kg; 93% at 43 mg/kg, and 50% at 4.3 mg/kg. Noteworthy dose‐related teratogenic effects of phenylethanol in offspring manifested themselves in increased incidences of malformed eyes, neural‐tube defects, hydronephrosis, and limb defects.
