Share of transfers using a carrier, by patient age (2022)
Dark: LARC · Light: U.S. average
Three-year trend, share of transfers using a carrier
| Patient age | 2020 | 2021 | 2022 | U.S. 2022 |
|---|---|---|---|---|
| <35 | 20% | 8% | 13% | 3% |
| 35-37 | 22% | 11% | 6% | 4% |
| 38-40 | 13% | 21% | 24% | 5% |
| >40 | 34% | 36% | 32% | 10% |
| All ages | 22% | 18% | 20% | 5% |
Total transfers (all egg sources, the CDC's denominator): 2020: 186 · 2021: 212 · 2022: 255
Volume estimate = the CDC's reported all-ages share of transfers that used a gestational carrier × the program's total transfers (the transfer count the CDC uses as that share's denominator). Where the CDC suppressed the all-ages share, the age-group shares are used instead and the tile says so.
For egg donation intended parents
Live births per transfer, donor egg cycles (2022)
67 transfers
Nearly all donor-egg transfers today are frozen embryo transfers — the embryo is frozen for genetic testing or scheduling whether the eggs were fresh or banked — so that is the figure to compare.
