OBJECTIVE: Low initial serum βhCG is a good predictor of early pregnancy failure. We
sought to determine the contribution of treatment variables and the predictive value of early …

Objective To evaluate which clinical characteristics influence early maternal β-human
chorionic gonadotropin (hCG) and progesterone levels in in vitro fertilization (IVF) …

The current study assessed the relationship between serum concentrations of human
chorionic gonadotrophin (HCG) measured in the peri-implantation period and various …

Background: Pregnancies achieved through in-vitro fertilisation (IVF) are associated with
adverse first trimester outcomes in comparison to spontaneously achieved pregnancies. In …

Objective To assess whether trophectoderm biopsy has any impact on the level of serum β-
human chorionic gonadotropin (β-hCG) in early pregnancies. Design Retrospective cohort …

OBJECTIVE: To correlate the live delivery rate with the initial level and rise of serum β-hCG.
DESIGN: Retrospective cohort analysis. SETTING: Large private academic center for …

Possible differences between serum HCG levels in pregnancies achieved after transfer of a
single fresh or a vitrified-warmed blastocyst were evaluated. Out of 1130 single blastocyst …

Objective To determine whether the serum β-human chorionic gonadotropin (hCG) profile
following preimplantation genetic diagnosis (PGD) is lower than that of intracytoplasmic …

Daily plasma beta-HCG levels from days 11 to 18 after ovum retrieval (OR) were evaluated
in a group of 73 women who became pregnant following in-vitro fertilization and embryo …

Purpose Maternal serum ß-human chorionic gonadotropin (ß-hCG) represents the
trophoblastic cell mass and is an indirect measurement of embryo development at early …
