Steroids in umbilical cord plasma from normal term deliveries.
Quantitation of nine steroids in 36 cord plasma samples and four plasma pools is reported and an attempt to isolate and quantitate oestetrol is described. A wide range of values was found, which did not show correlations to the weight of the newborn or of the placenta. Comparison with data from the literature are made and correlations among the steroid levels according to the sex of the foetus are looked for. The possible relationship of difference in HCG and steroid concentration according to the sex of the foetus is discussed.
