Effect of choline supplementation of embryo culture medium on in vitro production of blastocysts1
| Variable | Control | Choline | P-value |
|---|---|---|---|
| Oocytes undergoing cleavage, % | 72.9 ± 1.3 | 69.2 ± 1.3 | 0.290 |
| Oocytes becoming blastocyst, % | 17.2 ± 1.1 | 18.8 ± 1.1 | 0.490 |
| Cleaved embryos becoming a blastocyst, % | 24.6 ± 1.5 | 28.8 ± 1.6 | 0.326 |
1Data are least-squares means ± SEM of results from seven replicates representing 1,335 (control) or 1,332 (choline) cumulus-oocyte complexes (choline).
