Objective AI-assisted assessment of oocyte spindle structure at the moment of ICSI, supporting embryologist decision-making within one minute.
A minimal, focused interface designed for the pace of an IVF lab. Record 10-15 seconds of the oocyte under polarized light immediately before ICSI.
Capture directly from your lab computer display in real time. No separate recording device required.
Useful for labs without direct internet on the microscope workstation. Upload a pre-recorded file.
Quality verification, oocyte detection, spindle localization, and morphological scoring via ensemble model
Correlated with euploidy
Grey zone for inconclusive spindle morphology
Correlated with aneuploidy
Three-class scoring based on ensemble consensus, validated against PGT-A reference data in independent blinded studies.
High correlation with euploidy. Assigned when ensemble consensus indicates favorable spindle morphology.
Model confidence falls below the classification threshold. Accounts for 25-30% of all cases.
High correlation with aneuploidy.
Correlation accuracy for Scores A and C exceeds 70%, confirmed through independent blinded validation against PGT-A results.
Decision support only. Morphological scoring does not constitute a clinical diagnosis. All results should be evaluated by qualified reproductive medicine specialists in conjunction with standard clinical protocols.
Designed to integrate seamlessly into IVF laboratory routines with minimal disruption to existing protocols.
Every scored oocyte is logged with timestamp and optional ID. Records are searchable and exportable for clinical documentation.
When the model is uncertain, it reports Score B rather than making a forced prediction. The embryologist's own assessment always takes priority.
We provide hands-on training for embryologists on oocyte manipulation techniques that optimize spindle visualization under polarized light.
ReSpindle AI integrates with existing ICSI workstations — no hardware replacement required.
A polarization module on the ICSI microscope is the core hardware prerequisite. We do not manufacture or sell this equipment, but we can help connect you with authorized dealers in your region.
Plastic dishes introduce optical artifacts that degrade spindle visualization. Glass-bottomed culture dishes are required for reliable morphology assessment.
Correct oocyte orientation during video capture is essential. We provide protocol training as part of the onboarding process.
ReSpindle is certified as a Class I medical device under the European Medical Device Regulation (MDR). It is a decision support tool intended to assist embryologists with morphological pattern scoring, not for autonomous clinical decision-making.
No patient health information is collected or stored. Only the oocyte video is processed. An optional oocyte ID and free-text comment are available for lab reference. No third-party data sharing.
