 Context examples 


All four oestrogens were significantly elevated, on average, in the 98 foetuses who later developed autism, compared to the 177 foetuses who did not.

The other two types of stem cell in the blastocyst are the extra-embryonic trophoblast stem cells (TSCs), which will form the placenta, and primitive endoderm stem cells (PESCs) that will form the yolk sac, ensuring that the foetus’s organs develop properly and providing essential nutrients.

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.

(High levels of oestrogen in the womb linked to autism, University of Cambridge)

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.
