The Nature of Circulating Estrogen.

Experimental Biology and Medicine, 1946
SummaryThe total estrogen content of blood and sera obtained from normal, pregnant and gonadotrophin-injected animals and women was uniformly low. Values approximating 0.5 μg of alpha-estradiol equivalents per 100 cc of blood were found.Two-thirds of the total estrogen was closely associated with the protein fraction.
