Purpose To investigate hCG-β level on postovulatory day (POD) 12 and its fold increase as
predictors for pregnancy outcome after in vitro fertilization (IVF) cycles. Methods A …

Study Objective To assess the predictive value of a single serum human chorionic
gonadotropin (hCG) measurement obtained on day 14, 15, or 16 after transfer in in vitro …

Research question Do pregnancy, obstetric and perinatal outcomes differ according to initial
maternal serum human chorionic gonadotrophin (HCG) level measured on day 11 after …

An early marker predictive of a viable pregnancy would ease the anxiety associated with
positive pregnancy tests after the use of donor oocytes. We examined the predictive value of …

Introduction Prediction of pregnancy outcome after in vitro fertilization is important for
patients and clinicians. Early plasma human chorionic gonadotropin (p‐hCG) levels are the …

Objective Substantial previous studies have almost reached an agreement on the gender
effect on maternal serum human chorionic gonadotropin (MsHCG) in and after the late first …

The current study was undertaken to investigate the use of beta human chorionic
gonadotrophin (β-HCG) concentration and other significant factors to predict the likelihood of …

AIMS: Pregnancies achieved by in vitro fertilization (IVF) are at increased risk of adverse
outcome. The main objective of this study was to evaluate the predictive value of β-human …

Objective To determine if very early serum hCG, a marker of trophoblast differentiation, is
associated with adverse perinatal outcomes in singleton pregnancies. Design Retrospective …

This prospective study investigated the predictive value of pregnancy outcomes with serum
human chorionic gonadotropin (hCG) 7 days after day 3 embryo transfer (D3 ET), and …
