Brief summary

A pilot study to gather information on clinical pregnancy rates for preparation of the planning of a larger randomized controlled trial comparing two decision support tools: the deep learning tool iDAScore® and the current annotation model, KIDScore™ D5.

Interventions

Images of all the embryos reaching at least developmental stage of 3BB will be analyzed by iDAScore®. The embryo with the highest iDAScore® will be proposed for transfer.

Intervention model description

A pilot study randomizing embryos into two study groups comparing two decision support tools in the ranking of embryos for transfer.

Eligibility

ALL
Healthy volunteers
No

Inclusion criteria

1. Patients undergoing IVF/ICSI-treatment with controlled ovarian stimulation with gonadotrophins and the intention to treat by transfer of a single day 5 fresh blastocyst on day 5. 2. At least two good quality blastocysts (GQB) on day 5 (3BB or better on the Gardner scale), originating from normally fertilized oocytes (2PN).

Exclusion criteria

Planned transfer on day 2-4 6. Female age \>42 years 7. A reduced likelihood of obtaining two good quality blastocysts on day 5 as evidenced by an AFC \<5 (if available, AFC=antral follicle count)
