There is no significant difference in the morphology of ectopic pregnancy between the two patterns of β hCG clearance.

Demographic data of patients and morphological characteristics of ectopic pregnancies with successful expectant management. Group 1 (steady decline of serum β hCG levels from day 0 onwards (n = 97)); Group 2 (plateaued serum β hCG levels before decline (n = 33)). There is no significant difference in the morphology of ectopic pregnancy between the two patterns of β hCG clearance.
