Abstract. In 152 patients with an early pregnancy which was subsequently normal, we measured the maternal serum levels of estradiol (E2), progesterone (P4) and prolactin (PRL) as well as the diameter of gestational sac (GS) and the crown-rump length (CRL) of the embryo by transvaginal ultrasonography. The maternal serum level of E2 had the closest statistically significant correlation with both the GS diameter (r = 0.769, P 〈 0.01) and the CRL (r = 0.736, P 〈 0.001). P4 and PRL concentrations showed less correlation with embryo development.
