Information on embryos transferred: average embryos transferred, quality of embryos, further categorized by cleavage stage vs blastocyst and single vs multiple embryo transfers
| Transfer Cycle Number (%) | Embryos per Transfer | Good Quality Embryo (%) | Fair Quality Embryo (%) | Poor Quality Embryo (%) | |
|---|---|---|---|---|---|

Blastocyst Stage 1 ET |
145 (50) | 1 | 140 (96) | 4 (3) | 1 (1) |

Blastocyst Stage 1 ET |
87 (30) | 2.1 | 75 (86) | 10 (11) | 2 (2) |
| Total | 291 | 1.5 | 236 (81) | 38 (13) | 17 (6) |
Embryo Quality was defined as: Cleavage stage: Good = 8-cell with Grade 1 or 1.5, Fair = 6–10 cell with Grade 2 or better, Poor = 0-5-cell or 11+ -cell Grace 2.5-3; Blastocyst Good = 2BB or better, Fair = C x 1, Poor = Cx2
