STUDY QUESTION Is there an association between the length of in vitro culture, mode of
ART and the initial endogenous hCG rise, in cycles with a foetal heartbeat after single …

Study question Does the length in vitro and mode of ART (fresh and frozen cycles) impact
the se-hCG rise in cycles with ongoing single implantation pregnancy? Summary answer …

Fetal growth in early pregnancy was estimated by transvaginal ultrasonic measurement and
serum hCG measurement in 13 women who became pregnant through in vitro fertilization …

The hypothesis was tested that the medium used to culture embryos affects the
concentration of human chorionic gonadotrophin (HCG) early in pregnancy. The value of …

BACKGROUND: Assisted reproduction treatment (ART) entails a risk of ectopic pregnancy
and early pregnancy loss. Serum HCG has been found to be predictive of pregnancy …

STUDY QUESTION Do number of cells in the transferred cleavage stage embryo and
number of oocytes retrieved for IVF influence maternal hCG concentrations in early …

Background Previous investigations have suggested a controversial relationship between
serum estradiol levels on the day of HCG administration and pregnancy rates in women …

BACKGROUND: We aimed to characterize the rate of HCG rise associated with viable IVF
pregnancies, and to evaluate the association between HCG rise and potentially influential …

Objective It has been reported that the quantitative serum hCG level 14 days after embryo
transfer (ET) correlated with pregnancy outcome as well as a likelihood of a multiple …

Objective Current data suggests that LB following transfer of a euploid embryo is
independent of age or type of ART treatment. Because of their relatively uniform efficiency …
