Aggregated, de-identified statistics across every mitochondrial replacement therapy (MRT) procedure in the program. Every number here is a pooled total or rate across however many patients fall into that group — never a single patient's raw data shown on its own.
Biomaterial sent/used, and the conversion rates between stages, pooled within each age group. Blast rate is blasts ÷ used; euploid rate is euploid ÷ blasts.
| Age at retrieval | Patients | Sent | Used | Blast rate | Euploid rate |
|---|---|---|---|---|---|
| Under 40 | 0 | No data yet | |||
| 40-44 | 1 | 12 | 12 | 0% | — |
| 45+ | 4 | 46 | 44 | 61% | 11% |
Total oocytes/zygotes sent (M2 + M1 + GV + zygotes), divided by total live births achieved, within each age group.
| Age at retrieval | Patients | Biomaterial per live birth |
|---|---|---|
| Under 40 | No data yet | |
| 40-44 | 1 | No live births yet in this group |
| 45+ | 4 | 46.0 |
Pooled across every procedure in the program, from biomaterial sent through to embryo transfer.
| Stage | Count | % of previous stage |
|---|---|---|
| Biomaterial sent | 88 | — |
| Biomaterial used | 78 | 89% |
| Day 3 embryos | 28 | 36% |
| Day 5/6 blastocysts | 33 | 118% |
| Euploid embryos | 3 | 9% |
| Embryos transferred | 1 | 33% |
Pregnancies and live births are outcomes of a transfer, not of an individual embryo — see program totals above for those counts.
