title: Antenatal oestradiol and progesterone concentrations in patients subsequently having preterm labour.
abstract: Plasma levels of oestradiol and progesterone were measured in patients with a history of preterm labour but otherwise uncomplicated pregnancies who subsequently had a preterm labour. The plasma hormone levels were found to lie within the normal range, suggesting that the peripheral levels of these hormones do not play a role in the onset of labour before term.
