'A study of 145 preschool children reports, for the first time, that when the concentrations of two common phthalates in mothers’ prenatal urine are elevated their sons are less likely to play with male-typical toys and games, such as trucks and play fighting.

Because testosterone produces the masculine brain, researchers are concerned that fetal exposure to anti-androgens such as phthalates – which are pervasive in the environment – has the potential to alter masculine brain development, said lead author Shanna H. Swan, Ph.D., professor of Obstetrics and Gynecology, director of the URMC Center for Reproductive Epidemiology, and an expert in phthalates.
“Our results need to be confirmed, but are intriguing on several fronts,” Swan said. “Not only are they consistent with our prior findings that link phthalates to altered male genital development, but they also are compatible with current knowledge about how hormones mold sex differences in the brain, and thus behavior. We have more work to do, but the implications are potentially profound.”'
