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 threshold β-hCG levels predictive of an ongoing pregnancy (OP),
live birth (LB), and multiple gestation (MG) in IVF cycles resulting from day-3 (D3) vs. day-5 …

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

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 …

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 …

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

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 …

Objective It is difficult to predict whether an IVF cycle resulting in implantation will eventually
lead to a term pregnancy. Physicians commonly obtain a β-hCG level 14 days after embryo …

Background: Human Chorionic Gonadotropin (hCG) is secreted by the embryo as early as
the first week of life. Several studies have proven the potential of a single serum β hCG level …

OBJECTIVE: To compare β-hCG levels measured as the first pregnancy test in women who
conceived after in vitro maturation (IVM) or IVF. DESIGN: Retrospective matched cohort …
