Impact of Bisphenol A on Gonadotropic Hormone Levels in Children with Autism Spectrum Disorders.

Early developmental exposures to endocrine disruptors including bisphenol A (BPA) may affects the body's endocrine system producing adverse neurologic, reproductive, cardiovascular, metabolic, and immune effects in humans. Many studies show the effect of BPA on human reproduction at lower concentrations than that of the safety limit recommendations. However, limited studies have been associated between environmental exposure of BPA and gonadotropic hormone levels in children with autism spectrum disorders (ASDs). This study was done to evaluate association between the serum levels of hormones; follicle-stimulating (FSH), inhibin B (INHB), and estradiol (E2) and BPA in 49 ASD children compared with 40 healthy control children. Serum levels of FSH, INHB, and E2 were lower in ASD group than that of control. Correlations between BPA and FSH, INHB, and E2 within autistic children were not significant. The observed results revealed that BPA may cause endocrine dysfunction in ASD children.
