title: Oestrone, oestradiol and oestriol glucosiduronates and sulphates in human puerperal plasma and milk.
abstract: Conjugated and unconjugated oestrone, oestradiol and oestriol were measured in simultaneous milk and plasma samples obtained from 21 women in the early post-partum period. Conjugated oestrogens comprised more than 90% of the total oestrogen content of both milk and plasma. Oestrone glucosiduronate was the major oestrogen metabolite in milk (33%), the levels being significantly higher (P less than 0.01) than in plasma. Oestriol glucosiduronates were the predominant oestrogen metabolites (63%) in plasma.
