times of total β-hCG in serum (β-t2) in pregnant patients are also associated with a higher …

OBJECTIVE: To investigate the impact of delaying the transfer of in vitro fertilized embryos to
day 5 on embryo development by comparing serum β-hCG levels in pregnancies …

Objective What is the role of blastocyst morphology on day16 β-hCG serum levels and
pregnancy outcomes among patients who conceived through IVF cycles with single fresh …

Study question Is there a relationship between the concentration of the βhCG hormone in
maternal blood, embryo morphokinetics and clinical outcome? Summary answer βhCG …
