Summary In 20 normal pregnant women the excretion of oestrogen and creatinine during four fractions of a 24‐hour period was determined. For each urine specimen the total oestrogen content, the oestrogen concentration, the total creatinine content and the oestrogen‐creatinine ratio were studied. A peak of oestrogen excretion was found in the first fraction. The oestrogen‐creatinine ratio of the second fraction was most closely correlated to the 24‐hour oestrogen‐creatinine ratio.
