Characteristics of patients whose embryos were randomized to assessment by morphology with aCGH (Group A) and blastocyst morphology only (Group B)
| Group A (n = 55) | Group B (n = 48) | |
|---|---|---|
| Age (yrs) |
31.2 ± 2.5 |
31.5 ± 2.7 |
| Total oocytes retrieved |
19.5 ± 8.2 |
19.3 ± 8.1 |
| MII (mature) oocytes |
16.6 ± 7.8 |
16.3 ± 7.6 |
| Oocytes fertilized (2pn) |
13.1 ± 6.7 |
12.8 ± 6.4 |
| Day 3 embryos |
12.9 ± 1.8 |
12.6 ± 1.9 |
| Day 5 blastocysts | 8.3 ± 2.1 | 8.1 ± 2.4 |
Notes: Total number of blastocysts in Group [A] and [B] were 457 and 389, respectively. aCGH = array comparative genomic hybridization, MII = metaphase II, 2pn = two pronuclei. All data reported as mean ± SD. There was no significant difference between groups (p > 0.05) in any category.
