First Live Birth Rate With eSET After Preimplantation Methylome Screening (PIMS) Versus Conventional In-vitro Fertilization
- Conditions
- Reproductive Techniques, AssistedDNA Methylation
- Registration Number
- NCT05442125
- Lead Sponsor
- Shandong University
- Brief Summary
To determine whether using DNA methylome to select embryos can increase the live birth rate.
- Detailed Description
The rationale for the study is to establish the risk/benefit ratio of PIMS in women with in vitro fertilization (IVF) treatment, as DNA methylome is a potential biomarker in blastocyst selection in assited reproductive technology (ART). DNA methylation plays an important role during embryogenesis, global abnormal methylome reprogramming often occurs in human embryos, and DNA methylome pattern is associated with live birth rate. However, there is still no technology using DNA methylome as an indicator in preimplantation embryo screening. Recent paper reported that using Pre-implantation Methylome Screening (PIMS) can select embryos with better methylation state and euploid chromosomes. The efficiency of PIMS needs further validation through randomized clinical trial.

- Primary Outcome Measures
Name Time Method live birth rate of initial embryo transfer 22 months Live birth rate is defined as delivery of any viable infant at 28 weeks or more of gestation, after initial embryo transfer in women using the embryos selected through PIMS or PGT-A or morphological criteria alone.
- Secondary Outcome Measures
Name Time Method Maternal complications 48 months Number of pregnancies with complications / number of pregnancies.
Birth weight 36 months Weight of newborns at delivery.
Good Birth Outcome rate 36 months Defined as a live birth of an infant born at ≥ 37 weeks, with a birth weigh between 2500 and 4000g and without a major congenital anomaly
Pregnancy loss rate 36 months Number of pregnancy losses / number of clinical pregnancies after transfer.
Clinical pregnancy rate 36 months Twenty days after conception, transvaginal ultrasonography will be performed. Clinical pregnancy will be diagnosed with detection of an intrauterine gestational sac.
Duration of pregnancy 36 months Duration of pregnancy is the period between conception and birth.
Neonatal complications 48 months Number of live births with neonatal complications / number of live births.
Multiple pregnancy rate 36 months Number of multiple pregnancy/number of clinical pregnancies after transfer.
