Spindle-to-Oocyte Light Retardance Ratio for Oocyte Quality Assessment

581 mature oocytes from women aged ≤ 38 years undergoing IVF cycles at Lee Women’s Hospital from August 2024 to August 2025. The dataset likely contains polarized light microscopy measurements of spindle and zona pellucida birefringence, correlated with embryo development outcomes. It was authored by Chun-I Lee and published on figshare in May 2026.

Use Cases

• Predict usable blastocyst formation based on spindle-to-oocyte light retardance ratio (SOLRR)
• Compare embryonic progression timelines based on SOLRR groups
• Analyze correlations between polarized light imaging parameters and trophectoderm morphology
• Validate noninvasive oocyte quality assessment methods against time-lapse culture outcomes

Strengths

• 581 mature oocytes provide a substantial sample size for analysis
• Prospective cohort study design from a specific hospital (Lee Women’s Hospital)
• Includes multivariate analysis results with adjusted odds ratios for predictors

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is limited to a single hospital and women aged ≤ 38 years, which may introduce bias
