Brief summary

This is an observational, prospective, single-arm, multi-center, clinical study to evaluate the performance of CHLOE, an Artificial Intelligence (AI)-based software application, as adjunct information to support identifying embryos on Day 3 that are most likely to form blastocysts.

Detailed description

The study is an observational, prospective, single-arm, multi-center, clinical study in order to evaluate the performance of CHLOE, an Artificial Intelligence (AI)-based software application, as adjunct information to support identifying embryos on Day 3 that are most likely to form blastocysts on Day 5.

Interventions

DEVICECHLOE

CHLOE is designed to automatically analyze events related to embryo development from Time Lapse Incubator (TLI) images and provide prediction on the likelihood of embryos developing to the blastocyst. This information can assist embryologists and IVF professionals in the selection of the most viable embryo for transfer or freezing, when there are multiple embryos deemed suitable.

Inclusion criteria

* Women undergoing fresh IVF treatment using their own eggs * At least 18 years of age * Total antral follicle count (AFC) of at least 12 as measured by ultrasound prior to stimulation (in cases where AFC is performed) * Basal day 3 follicle-stimulating hormone levels (FSH) \< 10 IU * At least 8 normally fertilized eggs at pronuclear (2PN) stage * Fertilization using only ejaculated sperm (fresh or frozen) - no surgically removed sperm * At least 2 cells embryo * At least part of the embryos were cultured until Day 5 (i.e., 114-116 hours) * IVF treatment cycles were performed during 2020-2021

Exclusion criteria

* Use of re-inseminated eggs * Embryos that underwent day 3 biopsy for preimplantation genetic testing (PGT) * Gestational carriers * Concurrent participation in another clinical study * Previous enrollment in this clinical study (i.e., previous cycles of the same women) * History of cancer * Embryos that underwent biopsy at cleavage stage
