Which incubator grows better embryos? new trial aims to find out
NCT ID NCT06214936
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a benchtop incubator helps more embryos reach the blastocyst stage compared to a standard box incubator in people undergoing IVF. 252 participants will have their eggs split and placed in both incubators. The goal is to see which device supports better embryo development.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If benchtop incubators prove better, IVF labs may adopt them to improve embryo development rates.
- What could go wrong
- This is a small, early-stage study focused on lab outcomes, not pregnancy success. Results may not change clinical practice.

Inclusion Criteria for participants: 1. Patients undergoing an IVF cycle with plan for subsequent frozen embryo transfer (FET) of a single euploid embryo 2. 4 mature oocytes prior to randomization 3. Female partners age \<42 years old at start of their vaginal oocyte retrieval (VOR) cycle 4. Normal ovarian reserve: 1. Antimullerian Hormone Level (AMH) ≥ 1.2 ng/mL 2. Antral Follicle Count (AFC) ≥ 8 3. Follicle Stimulating Hormone (FSH) FSH ≤ 12international units (IU)/L 5. Body Mass Index (BMI) \<35 6. Patients who desire to transfer the best quality embryo for their embryo transfer. However, if a participant ends up electing to transfer based on sex preference after enrollment these outcomes will still be followed and included in the intention to treat analysis. Exclusion Criteria for participants: 1. All patients who do not voluntarily give their written consent for participation 2. Patients with a prior failed IVF cycle - defined as no blastocysts 3. Patients with a history of more than one failed euploid embryo transfer 4. Donor oocyte cycles 5. Gestational Carriers 6. Male partner with \<100,000 total motile spermatozoa per ejaculate (donor sperm is acceptable) 7. Use of surgical procedures to obtain sperm 8. Communicating hydrosalpinges without a plan for surgical correct prior to frozen embryo transfer 9. Endometrial Insufficiency, as defined by a prior cycle with maximal endometrial thickness \<6mm,), or persistent endometrial fluid 10. Single gene disorders, chromosomal translocations, or any other disorders requiring a more detailed embryo genetic analysis
