Abstract

Abstract: This prospective study investigated the predictive value of pregnancy outcomes with serum human chorionic gonadotropin (hCG) 7 days after day 3 embryo transfer (D3 ET), and whether estradiol (E2) and progesterone (P) improved the diagnostic efficiency. The study comprised 280 in vitro fertilization and embryo transfer (IVF-ET) cycles. Serum samples were obtained 7 days after D3 ET to measure hCG, E2, and P concentrations. Statistical analyses were conducted to evaluate the predictive value for pregnancy outcomes. We found significant differences in hCG level between pregnancy and non-pregnancy, viable and non-viable pregnancy, biochemical and viable pregnancy, as well as singleton and multiple pregnancy. An hCG cutoff value of 2.5 mIU/mL is predictive of pregnancy with a positive predictive value (PPV) of 95.9% and a negative predictive value (NPV) of 92.4%. An hCG value of 10.8 mIU/mL is predictive of a multiple pregnancy with an NPV of 98.1%. The area under the hCG curve between pregnancy and non-pregnancy was not improved by adding E2, P, or combined E2/P. Our results suggest a predictive value of pregnancy outcome with serum hCG drawn 7 days after D3 ET in IVF, and the diagnostic accuracy is not improved by adding measurements of E2/P.
