Abstract
Ortho-phthalate diesters, or phthalates, are widely used synthetic chemicals found primarily in consumer products and polyvinyl chloride plastics. Experimental evidence suggests that several phthalates possess antiandrogenic properties and may disrupt endocrine pathways resulting in abnormal reproductive outcomes. Low-level exposure to phthalates has been well documented in humans, with higher levels found in children and women of childbearing age. Recent epidemiologic studies postulate that prenatal exposure to measurable urine phthalate concentrations may be associated with altered genital and pubertal development in infants and children. This review addresses the emerging evidence that some phthalates may have an adverse impact on the developing brain. The supporting animal studies and proposed mechanisms underlying the deleterious properties of phthalates in relation to neurodevelopmental outcomes are also discussed. While the observed associations are based on limited studies with a broad range of endpoints, the implications of such outcomes are of concern from a public health standpoint and merit further investigation given the widespread nature of the exposure.
