High testosterone retards language skills in boys

Sydney: Boys exposed
to high levels of testosterone in the foetal stage are twice as
likely to experience retarded language development.
"An estimated 12 percent of toddlers experience significant delays
in their language development," said Andrew Whitehouse, associate
professor at Perth's Telethon Institute for Child Health Research.
"While language development varies between individuals, boys tend
to develop later and at a slower rate than girls," added
Whitehouse, who led the study.
The finding is significant for explaining why boys' language
development differs to that of girls, said Whitehouse, the Journal
of Child Psychology and Psychiatry reports.
Whitehouse said his team wanted to test whether this could be due
to prenatal exposure to sex-steroids such as testosterone,
according to Telethon statement.
They measured testosterone levels in the umbilical cord blood of
767 newborns before examining their language ability at one, two
and three years.
The results showed boys with high levels of testosterone in cord
blood were between two-to-three times more likely to experience
language delay. Male foetuses are known to have 10 times the
circulating levels of testosterone compared to females.
However, the opposite effect was found in girls where high-levels
of testosterone in cord blood were associated with a decreased
risk of language delay.
Previous smaller studies have explored the link between
testosterone levels in amniotic fluid and language development.
However, this is the first large population-based study to explore
the relationship between umbilical cord blood and language delay
in the first three years of life.
