Prenatal progesterone II. Its role in the treatment of pre-eclamptic toxaemia and its effect on the off-spring's intelligence: a reappraisal

Abstract

Dalton's results concerning the beneficial effect of progesterone supplementation in preventing pre-eclamptic toxaemia [16] and in enhancing intellectual potential [17,18] were reappraised. We could find no evidence in the data that progesterone supplementation was any better at preventing pre-eclamptic toxaemia than treating the disorder symptomatically. Nor could we find any convincing evidence that excess progesterone enhances development at 1 yr of age, academic attainment at 9--10 yr of age, or success in school leaving examinations and improves the chances of continuing further full-time education after leaving school.
