Brief summary
A non-inferiority, prospective parallel group, multi-center, randomized controlled trial to investigate whether selection of a single blastocyst for transfer using the deep learning tool, iDA, results in non-inferior clinical pregnancy rate compared to trained embryologists using standard morphology criteria.
Interventions
A system that studies time lapse images obtained from the embryo culture system, Embryoscope, throughout the development to blastocyst. The system uses data acquired from a sequence of embryo images and has taught itself to identify the embryos with the highest likelihood of implanting and leading to fetal heart-beat detection.

Eligibility
Inclusion criteria
1. Women undergoing IVF or ICSI with controlled ovarian stimulation with gonadotrophins and the intention to treat by either transfer of a single fresh embryo on day 5 or in case of a freeze all cycle, the first rewarmed embryo. 2. Age: Up to and including the 42nd completed birthday on the day of randomization. 3. Has at least two early blastocysts on day 5.
Exclusion criteria
1. Treatment involving donated eggs 2. Intention to perform any form of preimplantation genetic testing 3. The use of IMSI or polarized light in the ICSI process 4. The use of assisted hatching prior to randomization 5. Previous participation in this RCT 6. Where the cycle is carried out for fertility preservation 7. If a day 2-4 transfer is planned 8. Has a reduced likelihood of obtaining two early blastocysts on day 5 as evidenced by either: an AMH level of \<3pmol/L or AFC \<5 (if available)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Clinical Pregnancy Rate | After 7-9 weeks of gestation | Ultrasound evidence of an intrauterine pregnancy with a fetal heart observed |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Live Birth Rate | 9 months | Defined as the number of patients with at least one live birth after 22 completed weeks of gestation. If the exact gestational age is not known then a birth weight of ≥500gr can be used as a cut-off |
| Positive hCG Rate Per Randomized Patient | Tested on day 9-13 following embryo transfer | Defined as the number of patients with a positive β-hCG, determined by a hCG measurement from a blood sample or using urinary sticks |
| Rate of Non-viable Pregnancies | After 7-9 weeks of gestation | Defined as the difference between number of clinical pregnancies (excluding ectopic pregnancies) and number of positive β-hCG pregnancies |
| Ongoing Pregnancy Rate | After 7-9 weeks of gestation | Defined as the number of patients with a viable pregnancy at ≥12 weeks of gestation |

| Embryo Selection by Standard Morphologic Criteria The embryo for transfer will be selected by the embryologist on the basis of the morphologic appearances on day 5, according to the Gardner criteria using the ranking guideline. | 533 |
| Embryo Selection by iDA Time-lapse videos will be analyzed by iDA and the embryo for fresh transfer on day 5 will be prioritized on the strict basis of the embryo with the highest iDA score. For a frozen cycle; the first embryo to be warmed will be the one with the highest iDA score.
