Summary. Amniotic fluid concentrations of immunoreactive oestrogens and progesterone were measured at the time of caesarean section in 32 twin pregnancies; 25 women had an elective section and seven were in labour at the time of operation. No significant differences between concentrations in the amniotic fluid of the first and second twin were found in respect of conjugated and unconjugated oestrone, oestradiol, oestriol, oestetrol and unconjugated progesterone either before or during labour. It is unlikely that changes in oestrogens or progesterone in the amniotic fluid are responsible for the selective changes seen in prostaglandins and fetal adrenal steroid during labour in the first twin.
