Autism spectrum disorder (ASD) is a class of neurodevelopmental disorders that affects males more frequently than females. Numerous genetic and environmental risk factors have been suggested to contribute the development ASD. However, no one factor can adequately explain either frequency or male bias in its prevalence.

Phthalates, as other endocrine disrupting chemicals (EDCs), may alter the homeostasis and action of hormones signaling molecules, causing adverse health outcomes. This is true especially for infants, who are both more exposed sensitive to their effects. Phthalates particularly harmful when exposure occurs during certain critical temporal windows development, such prenatal early postnatal phases. also interfere with neuroendocrine systems (e.g., thyroid hormone or metabolism), disruption neuronal differentiation maturation, increasing risk behavioral cognitive disorders (ADHD autistic behaviors, reduced mental, psychomotor, IQ emotional problems).
