OBJECTIVE: To evaluate the correlation between basal serum FSH level before the fresh
IVF/intracytoplasmic sperm injection (ICSI) cycle and the clinical outcome of the subsequent …

OBJECTIVE: To determine whether elements of treatment associated with faster doubling
times of total β-hCG in serum (β-t2) in pregnant patients are also associated with a higher …

Background Initial low maternal serum β-human chorionic gonadotropin (β-hCG) is a good
predictor of early pregnancy demise. Our objective was to determine its predictive value in …

Recent studies suggest that elevated late follicular phase progesterone concentrations after
ovarian stimulation for IVF may result in embryo–endometrial asynchrony, reducing the …

Purpose There is no consensus yet in the literature on an optimal luteinizing hormone (LH)
level for human chorionic gonadotrophin (hCG) trigger timing in patients undergoing frozen …

Purpose To evaluate the relationship between serum β-human chorionic gonadotropin
(HCG) levels and early pregnancy outcomes in women who became pregnant using …

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 …

Objectives: To determine the prognostic value of beta human chorionic gonadotropin (ß-
hCG) concentration on the sixteenth day after embryo transfer to predict pregnancy outcome …

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

In the in vitro fertilization (IVF) and embryo transfer (ET) program at Yale, 32% of
pregnancies abort by 16 weeks. With the objective of predicting outcome, serum hCG titer s …
