BackgroundThis study aimed to explore whether an endometrial thickness (EMT) cutoff of 7 mm or 8 mm was more appropriate to define thin endometrium (TE) from the perspective of miscarriage and obstetric-neonatal complications.MethodsWe cond…

Clinical application of mesenchymal stem cells for endometrial repair has been hampered by variability in cell quality, large-scale production, and uncertainty regarding the optimal delivery route. In this study, we investigated the therape…

BACKGROUND: Endometrial thickness independently predicts pregnancy outcomes in frozen embryo transfer (FET) cycles. Thin endometrium always results in implantation failure and worse obstetric-neonatal outcomes. However, it has not been repo…

IntroductionPrevious studies have demonstrated that abnormal body mass index (BMI) is associated with adverse pregnancy outcomes in frozen-thawed embryo transfer cycles. However, the relationship between BMI and pregnancy and perinatal outc…

BACKGROUND: There is a higher risk of preterm delivery (PTD) in singleton live births conceived after in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) compared with spontaneously conceived pregnancies. The objective of o…

BACKGROUND: The utilization of frozen-thawed embryo transfer (FET) cycles has been linked to heightened risks of adverse perinatal outcomes. However, the potential association between adverse perinatal outcomes and distinct endometrial prep…

BACKGROUND: Thin endometrium on ovulation triggering day is associated with impaired pregnancy outcomes in women after in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI), but the role of thick endometrium on pregnancy outcom…

BACKGROUND: The HOXA10 homeobox gene controls embryonic uterine development and adult endometrial receptivity. The three-amino-acid loop extension (TALE) family homeobox genes like myeloid ecotropic viral integration site 1 (MEIS) provide e…
