Table 3 Embryo scores and mean numbers of blastomeres of the early-cleavage and late-cleavage subgroups in the antagonist group.

From: Early-cleavage is a reliable predictor for embryo implantation in the GnRH agonist protocols but not in the GnRH antagonist protocols

  Early-cleavage subgroup Late-cleavage subgroup P value
Day 2 embryo score 1.92 ± 0.04 2.11 ± 0.04 NS
No of day 2 blastomeres 4.11 ± 0.06 3.21 ± 0.06 < 0.05
Day 3 embryo score 2.02 ± 0.06 2.10 ± 0.06 NS
No. of day 3 blastomeres 7.29 ± 0.10 7.18 ± 0.10 NS
Pregnancy rate (%) 45.9 (45/98) 43.8 (46/105) NS
