Table 4. Proportion of embryos that reach day 3 and proportion of embryos that develop to blastocyst, by cycle and for the study groups.
Mean (95% IC) p
D3 RATE (%) Fresh sperm 98.05 (97.38-98.72) 0.501
Frozen sperm 97.69 (96.87-98.51)
Total 97.90 (97.38-98.41)
BLASTOCYST RATE (%) Fresh sperm 68.68 (65.73-71.63) 0.682
Frozen sperm 67.76 (64.51-71.01)
Total 68.28 (66.10-70.46)

*Development rate on D3: Proportion of embryos that reach day 3 with respect to correctly fertilized oocytes. Blastocyst rate: proportion of embryos that develop to blastocyst with respect to viable embryos on day 3. The results are presented as a percentage (95% CI). The significance level was considered to be 5%, so p value< 0.05 is considered significant.
