Objective What is the role of blastocyst morphology on day16 β-hCG serum levels and
pregnancy outcomes among patients who conceived through IVF cycles with single fresh …

Objective To determine the effect of embryonic factors on serum beta human chorionic
gonadotropin (β-hCG) levels in pregnancy and live birth resulting after a single fresh …

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 …

Objective (s) Beta human chorionic gonadotrophin (β-hCG) is secreted by placenta and
detectable in maternal serum a few days after embryo implantation. The evolution of 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 …

Study question Is there a relationship between the concentration of the βhCG hormone in
maternal blood, embryo morphokinetics and clinical outcome? Summary answer βhCG …

Objective Is there an association between blastocyst morphology and maternal first trimester
serum markers in In Vitro Fertilization (IVF) pregnancies obtained after fresh single …

The aim of this study was to assess the ability of three individual blastocyst morphology
parameters–expansion and hatching (EH) stage, inner cell mass (ICM) grade and …

Purpose The objective of this study is to identify the pregnancy outcomes based on day-16 β-
hCG level assessed with modern assays, in fresh single embryo transfers. Methods A …

Objective: To assess the predictive value for clinical pregnancy outcome of β-hCG level at
13 d after embryo transfer. Methods: Retrospective study of IVF clinical pregnancies …
