High levels of estrogen in the womb linked to autism
Science Daily
Scientist have identified a link between exposure to high levels of oestrogen sex hormones in the womb and the likelihood of developing autism. The findings are published today in the journal Molecular Psychiatry.

The discovery adds further evidence to support the prenatal sex steroid theory of autism first proposed 20 years ago.

In 2015, a team of scientists at the University of Cambridge and the State Serum Institute in Denmark measured the levels of four prenatal steroid hormones, including two known as androgens, in the amniotic fluid in the womb and discovered that they were higher in male foetuses who later developed autism. These androgens are produced in higher quantities in male than in female foetuses on average, so might also explain why autism occurs more often in boys. They are also known to masculinise parts of the brain, and to have effects on the number of connections between brain cells.

Another recent study:

Genetic factors are primary cause of autism, study finds
The largest study of its kind, involving more than 2 million people across five countries, finds that autism spectrum disorders are 80 percent reliant on inherited genes.

That means that environmental causes are responsible for just 20 percent of the risk.

The findings could open new doors to research into the genetic causes of autism, which the U.S. Centers for Disease Control and Prevention now says affects 1 in every 59 U.S. children.

It might also help ease fears that autism is caused by maternal factors -- a mother's weight, mode or timing of delivery, or nutrient intake, for example. The new study found the role of maternal factors to be "nonexistent or minimal."
The role of maternal factors is "nonexistent or minimal."

After reading both articles carefully, they don't necessarily contradict each other. However, the one regarding hormones in amniotic fluid seems to be based on 98 samples and a control group of 177 whereas the other one is based on millions of subjects.
