Objective. Analysis of serum β-human chorionic gonadotropin (β-hCG) levels on
standardized days after oocyte retrieval (OR) following single blastocyst transfer to predict …

Objective: To determine the predictive value (s) of β–hCG serum levels for pregnancy
outcome following blastocyst transfer. Design: Retrospective review. Setting: University …

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 Specific serum beta human chorionic gonadotropin (β-hCG) parameters that can
predict live birth after an embryo transfer have yet to be defined. Methods We performed a …

Purpose: Our purpose was to assess the predictive value for pregnancy outcome of an initial
serum quantitative β-hCG measurement obtained 11 or 12 days after embryo transfer in an …

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 …

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 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 …

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 …

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 …
