This prospective observational study will assess endometrial peristalsis at predefined time points during HRT-prepared FET cycles using transvaginal ultrasonography and evaluate its association with pregnancy outcomes. The study aims to clarify the clinical significance of endometrial peristalsis in HRT-prepared FET cycles and to provide evidence supporting endometrial assessment in assisted reproductive technology.",[25,26,27,28,29,30,31],"Infertility","Endometrial Peristalsis","Uterine Contraction","Endometrial Waves","Frozen Embryo Transfer (FET)","Uterine Peristalsis","Hormone Replacement Therapy (HRT)",[33,34,35,36,37],"endometrial peristalsis","uterine contractions","endometrial waves","frozen embryo transfer","artificial cycles","NOT_YET_RECRUITING","2026-06-29",{"date":41,"type":42},"2026-07-01","ACTUAL",{"date":44,"type":21},"2026-06-30",{"date":46,"type":21},"2027-12-01",{"name":48,"class":49},"Mỹ Đức Hospital","OTHER",""]
