  1. Values are given as mean±SEM. n = number of blastocyst
  2. Values with the same letters in the treatment groups within column are not significantly different
  3. Values in the treatment groups with asterisk are significantly different from the unsupplemented group
  4. Group I (Unsupplemented group), Group II (Pregestation only group), Group III (Pregestation-to-gestation group), and Group IV (Gestation only group)
