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 …

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 …

The aim of this study is to compare the serum β-hCG values post transfer of a cleavage
stage embryo versus a blastocyst stage embryo at equal time intervals post oocyte retrieval …

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 …

Objective To study the predictive value of serum β-hCG on day 5 after frozen-thawed embryo
transfer (FET) to predict pregnancy outcomes and to establish cut-off values for very early …

Research question Does the blastocyst development stage on embryo transfer day affect
serum β-human chorionic gonadotrophin (β-HCG) concentration 9 and 16 days after embryo …

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 …

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 …

Background This study aimed to examine maternal serum concentration of β‐human
chorionic gonadotropin (β‐hCG) on Day 16 after embryo transfer and risk of miscarriage, pre …
