[10] [15] During normal human pregnancy, estrogen production increases progressively and extremely high estrogen levels are attained. [19] Estradiol levels range from 1,000 to 40,000 pg/mL across pregnancy, [20] are on average 25,000 pg/mL at term, and reach levels as high as 75,000 pg/mL in some women. [21
