SERUM HCG RISE AMONG SINGLE AND DOUBLE EMBRYO TRANSFER PREGNANCIES THAT RESULT IN LIVE BIRTH

Abstract

Critical to the diagnosis and interpretation of early pregnancy, the rise of serum hCG levels following embryo transfer is a source of concern for both patients and providers. A slow rise in hCG levels may suggest an early pregnancy loss or ectopic pregnancy, frequently at a gestational age when ultrasound evaluation is inconclusive. Little is known regarding the rise in hCG in women who have a single (SET) or double embryo transfer (DET) and the prevalence of a slow rise among women who subsequently have a live birth.
