Objective To assess perinatal outcomes and placental findings after in vitro fertilization (IVF)
with an initial low serum β-human chorionic gonadotropin (hCG). Design A retrospective …

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 …

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 Initial serum HCG levels are measured less than two weeks after FET, and
interpretation of HCG levels is crucial in early diagnosis of viability of pregnancies. Prior …

Background Increasing data indicates that the presence of a corpus luteum (CL) during
frozen embryo transfer (FET) impacts downstream maternal outcomes such as …

Objective: To analyze the success rate of true natural cycle in patients undergoing frozen
thawed embryo transfers. Materials and Methods: This retrospective analysis included …

Objective The aim of the study was to evaluate the predictive value of the human chorionic
gonadotropin (hCG) concentration on the 14th and 16th post-ovulation day after embryo …

Purpose To assess the influence of intrauterine human chorionic gonadotropin (hCG) before
embryo transfer on the clinical pregnancy and live birth rates after vitrified-warmed embryo …

Objective To examine how early serum human chorionic gonadotropin (hCG) levels predict
live birth (LB) after single embryo transfer (SET). Materials and Methods All fresh and frozen …

Background: Timing of frozen embryo transfer (FET) within a purported window of
implantation is of increasing interest, and there is a paucity of evidence surrounding the …
