Objective: The relationship between serum beta human chorionic gonadotropin (β-hCG)
levels of patients (7 days after the transplantation of frozen-thawed embryos) and the …

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 …

Objective To determine the relationship between serum levels of the β-subunit of human
chorionic gonadotropin (β-hCG) on day 24 of pregnancy during a frozen embryo transfer …

Study question What is the role of the initial β-hCG value and the β-hCG rate of increase
after 2 days in the predictability of the pregnancy outcomes? Summary answer The initial β …

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 …

Purpose The study was designed to investigate the effect of vitrification and slow freezing for
the cryopreservation of human day 3 embryos on serum β-hCG levels in pregnancies …

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

To investigate whether the initial beta-human chorionic gonadotropin (β-hCG) levels and
their rate of increase differ after single fresh and frozen blastocyst transfers, and whether …

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 …

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 …
