Prenatal exposure to testosterone appears to affect language development -- and to do so differently in males than in females, researchers found.

Males exposed to the highest testosterone levels were more than twice as likely to have a language delay at age 3 (OR 2.47, 95% CI 1.12 to 5.47), according to Andrew Whitehouse, PhD, of the University of Western Australia in Perth, and colleagues.

Conversely, females exposed to the highest levels had a reduced likelihood of having a language delay at that age (OR 0.46, 95% CI 0.21 to 0.99), the researchers reported online in the Journal of Child Psychology and Psychiatry.

I have always thought girls talked sooner, and more, than boys because they had a lot to say.
