AbstractPurpose: Our purpose was to assess the predictive value for pregnancy outcome of an initial serum quantitative β-hCG measurement obtained 11 or 12 days after embryo transfer in an in vitro fertilization program. Methods: A prospective, descriptive study of 153 pregnancies achieved via in vitro fertilization-embryo transfer was performed. Initial β-hCG levels and subsequent pregnancy outcomes were compared. Results: The overall mean initial β-hCG level was 91±85.8 mIU/ml for normal… 
Early Maternal Serum β-human Chorionic Gonadotropin Measurements After ICSI in the Prediction of Long-term Pregnancy Outcomes: A Retrospective Cohort Analysis
TLDR
In ICSI pregnancies, a single early β-hCG may help to identify pregnancies that will reach full-term and delivery and demonstrate a high sensitivity for identifying patients with ectopic pregnancies and early miscarriage.
Predictive value of early serum β‐hCG levels after single blastocyst transfer
TLDR
The predictive value of a single β‐hCG measurement for pregnancy outcome after single blastocyst transfer increases between days 11 and 21 after OR, and may balance the accuracy of prediction and the necessity of an early reassuring test.
Pregnancy Outcomes of Patients with Low Serum β-hCG Level 14 Days After Fresh Embryo Transfer
TLDR
Initially low serum β-hCG level 14 days after day 3 embryo transfer indicated poor prognosis with minimal likelihood of ongoing pregnancy.

TLDR
The likelihood of live birth was minimal with low serum β-hCG level 14 days after embryo transfer, and the rates of biochemical pregnancy and live birth were 99.5% and 92.4%, respectively.
Maternal age and serum β-hCG concentrations at 14-16 days after embryo transfer are predictive factors for spontaneous abortion in IVF / ICSI cycles in Northeast China
TLDR
Maternal age, serum β-hCG concentrations at 14-16 days after embryo transfer, and logistic models are useful tools in predicting pregnancy outcomes following IVF-ET.

Serum progesterone levels predict success of in vitro fertilization/embryo transfer in patients stimulated with leuprolide acetate and human menopausal gonadotropins.
TLDR
It is demonstrated that even modest increases in serum P4 levels (greater than 1.27 nmol/L) are associated with reduced pregnancy rates in IVF/ET cycles, and the mechanism may not exclusively involve poor oocyte quality.
Sonographic appearance of the endometrium: the predictive value for the outcome of in-vitro fertilization in stimulated cycles.
TLDR
The predictive value for pregnancy of the endometrial thickness and pattern assessed by vaginal sonography on the day of human chorionic gonadotrophin (HCG) injection and the day in 74 stimulated cycles for in-vitro fertilization (IVF) which were analysed prospectively is evaluated.
Small increases in circulating luteinizing hormone (LH) concentrations shortly before human chorionic gonadotropin (hCG) are associated with reduced in vitro fertilization (IVF) pregnancy rate
TLDR
The effects of slight elevations in serum LH just before hCG administration on IVF cycle outcome were studied in 219 women undergoing retrieval and a ≥50% rise in LH before h CG was associated with a significantly reduced IVF pregnancy rate.
