Now a new study has found that altering the androgens of a fetus during early pregnancy -- this time by by-products of PVC (the plastic pipes found in most home plumbing) -- can not only alter the gender of the brain but can change the formation of the genitals in the newborn.
Phthalate Exposure Linked to Less-Masculine Play by Boys
A study of 145 preschool children reports in the International Journal of Andrology, 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.
What's the big deal here? Well for years psychologists have looked for ways to predict homosexuality in children. They were trying to see at what age the child "chose" to be gay. One of the most reliable clues to homosexuality was detected in the types of toys and play activities that children preferred.
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 cautiously. "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." www.viewzone.com...
