NCT06377917

Brief Summary

This study aims to assess the clinical significance of cleavage stage (Day 3) assisted hatching compared to assisted hatching at the blastocyst stage (Day 5,6,7) of embryo development at the time of trophectoderm (TE) biopsy for patients undergoing in vitro fertilization (IVF) and preimplantation genetic testing for aneuploidy (PGT-A) for treatment of their infertility.

Outcome Measures

Primary Outcomes (1)

  • Blastulation Rate

    Blastulation rate per 2 pronuclei (PN) in each group

    1 week after vaginal oocyte retrieval (VOR)

Secondary Outcomes (7)

  • Embryo morphologic grade

    1 week post VOR

  • Timing of blastulation

    1 week post VOR

  • Aneuploidy rate

    2 weeks post blastulation

  • Positive pregnancy rate

    approximately 9 days post embryo transfer

  • Sustained implantation rate

    8-9 weeks gestational age or approximately 5-6 weeks post embryo transfer

  • +2 more secondary outcomes

Study Arms (2)

Cleavage Stage Assisted Hatching (AH)

OTHER

Current standard of care. Day 3 or cleavage stage embryos will have the zona pellucida hatched with a laser.

Other: Laser Assisted Hatching

Blastocyst Stage Assisted Hatching (AH)

EXPERIMENTAL

Blastocyst stage embryos on day 5,6 or 7 will have the zona pellucida hatched with a laser.

Other: Laser Assisted Hatching

Interventions

Laser Assisted HatchingOTHER

Routine assisted hatching procedure will be performed on both groups at the different embryo developmental phases.

Eligibility Criteria

Age18 Years - 42 Years
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Patients undergoing an IVF cycle with plan for subsequent FET of a single euploid embryo
  • \<4 2PNs prior to randomization
  • Female partners age \<42 years old at start of VOR cycle
  • Normal ovarian reserve:
  • AMH ≥ 1.2 ng/mL
  • AFC ≥ 8
  • FSH ≤ 12IU/L
  • BMI \<38
  • Patients who desire to transfer the best quality embryo for their embryo transfer.

You may not qualify if:

  • All patients who do not voluntarily give their written consent for participation
  • Patients with a prior failed IVF cycle - defined as no blastocysts
  • Patients with a history of more than one failed euploid embryo transfer
  • Donor oocyte cycles
  • Gestational Carriers
  • Male partner with \<100,000 total motile spermatozoa per ejaculate (donor sperm is acceptable)
  • Use of surgical procedures to obtain sperm
  • Communicating hydrosalpinges without a plan for surgical correct prior to frozen embryo transfer
  • Endometrial Insufficiency, as defined by a prior cycle with maximal endometrial thickness \<6mm,), or persistent endometrial fluid
  • Single gene disorders, chromosomal translocations, or any other disorders requiring a more detailed embryo genetic analysis than standard PGT-A
