Brief Summary:
The study is conducted to evaluate the sensitivity and specificity of non-invasive preimplantation genetic testing for aneuploidy (NiPGT-A) using cell free DNA into spent culture medium (SCM).

Condition or disease Intervention/treatment
Preimplantation Genetic Testing (PGT) ICSI Diagnostic Test: NiPGT-A

Detailed Description:

Our study is a diagnostic study, recruit 218 biopsied blastocysts from couples undergoing intracytoplasmic sperm injection (ICSI) with Preimplantation genetic testing for aneuploidy (PGT-A) or Preimplantation genetic testing for structural rearrangements (PGT-SR) indication.

Oocyte retrieval, ICSI and embryo culture are performed by routine protocol.

On day 3, each embryo was washed and cultured in single droplets. TE biopsy was conducted and 10μl SCM of biopsied embryos are collected on day 5 or day 6. Both sample types undergo whole-genome amplification (WGA) using Quanti Flour ONE dsDNA system and DNA analysis by next-generation sequencing (NGS) using NextSeq High output 150 cycles kit.

Comparison of NGS results from trophectoderm (TE) biopsy and SCM is done to identify the sensitivity and specificity of the test.

A sample size of 218 day 5/day 6 embryos will be needed.

Group/Cohort Intervention/treatment
Patients with PGT indication
Patients undergo in vitro fertilization with PGT-A or for PGT-SR indication
Diagnostic Test: NiPGT-A
NiPGT-A is the technique to screen the aneuploidy status of an embryo without invasion technique, such as biopsy. We use SCM to isolate cfDNA, then amplify and analyse the aneuploidy of embryo secreting this material using NGS technique.

Primary Outcome Measures :
  1. Sensitivity of NiPGT-A [ Time Frame: 4 months after recruiting ]
    The ability to detect euploid embryo

  2. Specificity of NiPGT-A [ Time Frame: 4 months after recruiting ]
    The ability to detect aneuploid embryo

Secondary Outcome Measures :
  1. Successful amplification rate [ Time Frame: 7 days after SCM collection ]
    Rate of SCM samples with DNA concentration after WGA greater than or equal 1ng/μl

  2. Total concordance [ Time Frame: 14 days after SCM collection ]
    The match NGS results from TE biopsy and SCM for ploidy and sex

  3. Positive pregnancy rate [ Time Frame: at 2 weeks after embryo transfer ]
    Rate of participants with serum human chorionic gonadotropin level greater than 25 mIU/mL

  4. Clinical pregnancy rate [ Time Frame: 5 weeks after embryo transfer ]
    Rate of participants with at least one gestational sac on ultrasound at 7 weeks' gestation with the detection of heart beat activity.

  5. Ongoing pregnancy rate [ Time Frame: At 12 weeks' gestation ]
    Rate of participants with detectable heart at 12 weeks' gestation or beyond, after the completion of the first transfer

  6. Implantation rate [ Time Frame: 3 weeks after embryo transfer ]
    as the number of gestational sacs per number of embryos transferred

Biospecimen Retention:   Samples With DNA
TE biopsy of blastocyst and cfDNA into spent culture media.
