Objective To investigate the value of serum beta-human chorionic gonadotropin (β-HCG) on
days 9 (d9) and 11 (d11) after fresh embryo transfer (ET) and frozen-thawed embryo transfer …

Objective Early monitoring of plasma human chorionic gonadotropin (β-hCG) level is vital in
predicting pregnancy outcome. This study investigated the predictive value of serum β-hCG …

As one of the earliest markers for predicting pregnancy outcomes, human chorionic
gonadotropin (hCG) values have been inconclusive on reliability of the prediction after …

Serum level of beta-subunit of human chorionic gonadotropin (beta-hCG) at the post-ET day
16 was studied to evaluate its predictability of pregnancy outcome in 165 patients in vitro …

OBJECTIVE: To assess the clinic value of a single maternal serum beta-human chorionic
gonadotropin (2-hCG) assay 11 d after embryo transfer in ART pregnancies and to predict …

Purpose To evaluate the relationship between serum β-human chorionic gonadotropin
(HCG) levels and early pregnancy outcomes in women who became pregnant using …

Purpose The aim of the present study was to evaluate if the live birth predictive values of β-
hCG levels differ in fresh and vitrified-warmed blastocyst transfer cycles. Methods In the …

We previously explored the associations between β-hCG on the 14th day post–embryo
transfer (ET) and reproductive outcomes and established a series of cutoff values to predict …

Background Although prior work has attempted to predict pregnancy outcomes by assaying
serum β-hCG levels after blastocyst transfer, no study has focused on pregnancy outcomes …

Objectives: To study the value of βhCG on day 11 after embryo transfer in predicting the
early outcome of pregnancy after in vitro fertilization. Materials and methods: A prospective …
