Brief Summary
Researchers aim to determine how baseline (pre-conceptional) uterine perfusion characteristics affect implantation rates and obstetric complications in women who underwent high-quality blastocyst transfer.

Outcome Measures
Primary Outcomes (2)
Live Birth Rate
pregnancy beyond 24 weeks of gestational age.
9 months
Obstetric Complication Rates
Conditions such as preeclampsia, eclampsia, fetal growth restriction, oligohydramnios, polyhydramnios, preterm birth, gestational diabetes mellitus, antenatal bleeding and etc. that develop during pregnancy
24th gestational weeks till delivery
Secondary Outcomes (1)
Positive β-hCG results
Nine days after each embryo transfer
Study Arms (3)
non-pregnant
negative b-hCG results 9 days after embryo transfer.
pregnant with obstetric complications
Patients with a positive pregnancy result who develop obstetric complications such as preeclampsia, eclampsia, fetal growth restriction, oligohydramnios, polyhydramnios, preterm birth, gestational diabetes mellitus, antenatal bleeding and etc. after the 20th gestational weeks.
pregnant without obstetric complications
Patients who have positive pregnancy results and do not have any obstetric complications such as preeclampsia, eclampsia, fetal growth restriction, oligohydramnios, polyhydramnios, preterm birth, gestational diabetes mellitus, antenatal bleeding and etc. during pregnancy.
Eligibility Criteria
All patients who have artificial endometrial preparation with high-quality blastocysts between May 2022 and December 2022 will be included. All included patients will have bilateral uterine artery Doppler velocimetry on 2-5 days of their menstrual cycle by transvaginal ultrasonography.
You may qualify if:
- Exogenous hormone preparation of the endometrial lining
- High embryo quality ((≥2BB) according to Alpha criteria
- Embryo transfer at the blastocyst stage
You may not qualify if:
- Patients whose treatments were canceled for any reason before the embryo transfer procedure
- Patients who underwent embryo transfer in the cleavage stage
- Presence of low-quality (\<2BB) blastocysts
- \>15% loss of viability of the embryo during embryo thawing,
- Patients with congenital uterine malformations,
- Patients in whom Doppler velocimetry cannot be performed optimally
