C = COMPETENCY · B = BENCHMARK
KPI 01Fertilization

ICSI Damage Rate

Measures procedural trauma during sperm injection. Lower is better — reflects needle control precision.

Damage rate
BC
C · Competency≤ 10%
B · Benchmark≤ 5%
KPI 02Fertilization

ICSI Normal Fertilization Rate

Proportion of injected MII oocytes that fertilize normally (2PN + 2PB). A core quality marker for ICSI success.

Normal fertilization rate
CB
C · Competency≥ 65%
B · Benchmark≥ 80%
KPI 03Fertilization

IVF Normal Fertilization Rate

Assesses how well conventional IVF converts inseminated COCs into normally fertilized oocytes.

Normal fertilization rate
CB
C · Competency≥ 60%
B · Benchmark≥ 75%
KPI 04Fertilization

Failed Fertilization Rate (IVF)

Tracks cycles where no fertilization occurred at all. A critical alert metric — high rates warrant protocol review.

Failed fertilization rate
T
T · Target< 5%
Alert level≥ 5%
KPI 05Embryo development

Cleavage Rate

Shows how successfully fertilized oocytes progress to the cleavage stage by Day 2. Reflects culture conditions.

Cleavage rate
CB
C · Competency≥ 95%
B · Benchmark≥ 99%
KPI 06Embryo development

Day 2 Embryo Development Rate

Measures proportion of normally fertilized oocytes reaching the ideal 4-cell stage by Day 2. Key early quality indicator.

Day 2 development rate
CB
C · Competency≥ 50%
B · Benchmark≥ 80%
KPI 07Embryo development

Day 3 Embryo Development Rate

Tracks progression to 8-cell stage — a critical checkpoint reflecting both embryo quality and lab culture conditions.

Day 3 development rate
CB
C · Competency≥ 45%
B · Benchmark≥ 70%
KPI 08Embryo development

Blastocyst Development Rate

The proportion reaching blastocyst by Day 5. Strongly predicts overall lab performance and implantation potential.

Blastocyst development rate
CB
C · Competency≥ 40%
B · Benchmark≥ 60%
KPI 09Advanced procedures

Successful Biopsy Rate

Assesses the technical success of embryo biopsy — essential for PGT labs where DNA detection is the primary goal.

Successful biopsy rate
CB
C · Competency≥ 90%
B · Benchmark≥ 95%
KPI 10Advanced procedures

Blastocyst Cryosurvival Rate

Evaluates vitrification technique quality. High survival rates are essential for FET success and cumulative pregnancy outcomes.

Cryosurvival rate
CB
C · Competency≥ 90%
B · Benchmark≥ 99%
KPI 11Implantation

Implantation Rate — Cleavage Stage

Shows what proportion of cleavage-stage embryos successfully implant. Reflects both embryo quality and uterine receptivity.

Implantation rate — cleavage
CB
C · Competency≥ 25%
B · Benchmark≥ 35%
KPI 12Implantation

Implantation Rate — Blastocyst Stage

Higher implantation expected at blastocyst stage. A benchmark metric for advanced IVF programs using Day 5 transfer.

Implantation rate — blastocyst
CB
C · Competency≥ 35%
B · Benchmark≥ 60%
