mothers
who had received progesterone during pregnancy
together with the next-born normal child in the
labour ward register, and the names of all those
who had developed toxaemia. Permission to in￾corporate them in a survey was obtained from the
mothers in respect of 45% of the progesterone
children and 47~0 of control children who were
then 9-10 years old. Their schools were contacted
and head teachers were asked to assess the child's
ability in verbal reasoning, English, arithmetic,
craftwork and physical education. These results
confirmed the superiority of the progesterone
children in academic subjects but not in craftwork
or physical education. Toxaemia was associated
with lowered intelligence as was expected from
earlier studies (Barker & Edwards 1967).
Furthermore, the effect was dose dependent, with
those receiving progesterone before the 16th week
and in the higher dose showing the greatest
advantage
