title: Comparison of first trimester serum estradiol levels in aborters versus nonaborters during maintenance of normal progesterone levels.
abstract: This study was designed to measure the average serum estradiol (E2) levels in the first trimester for women whose serum progesterone (P) levels were carefully maintained at normal levels by the use of exogenous P, and to compare the mean serum E2 levels in women who aborted with those in women who did not. The study group consisted of 94 pregnant women supported with exogenous natural P therapy from the luteal phase through the first trimester. Beginning at week 5, and continuing through the first trimester, the mean serum E2 levels for nonaborters were significantly higher than those for aborters.
