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 …

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 …

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 …

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 present study investigated the role of β-hCG in predicting reproductive
outcomes and established optimal β-hCG cutoff values in women undergoing cleavage …

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 …

This study evaluated β-human chorionic gonadotropin (hCG) changes during the early
period of pregnancy in an attempt to predict successful pregnancy outcomes in ART. It …

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

Mid-trimester beta-human chorionic gonadotropin (BHCG) levels are considerably higher in
pregnancies resulting from frozen embryo transfer (FET) compared with fresh (FRET) …

Purpose Few published articles have compared initial hCG values across all different types
of ART cycles, including cycles with fresh or frozen embryo transfer. No articles have …
