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 …

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 …

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 …

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 …

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 …

Objective To investigate the pregnancy outcomes of patients with low serum β-hCG level 14
days after day 3 embryo transfer. Methods A retrospective study was performed with 723 …

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 …

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 …

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 …

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 …
