Table 1 Characteristics of patients whose embryos were randomized to assessment by morphology with aCGH (Group A) and blastocyst morphology only (Group B)

From: Selection of single blastocysts for fresh transfer via standard morphology assessment alone and with array CGH for good prognosis IVF patients: results from a randomized pilot study

  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
  1. 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.
