“…EG is better able to [16], and replaces water to reduce the formation of ice crystals. However, in the current study, the percentage of dead cells in EG-frozen embryos (5.0% and 4.6% in horse and donkey embryos, respectively) was similar to that described using glycerol [18], and lower than rates reported by others [3,12,19,20]. However, in the current study, the percentage of dead cells in EG-frozen embryos (5.0% and 4.6% in horse and donkey embryos, respectively) was similar to that described using glycerol [18], and lower than rates reported by others [3,12,19,20].…”

“…The percentage of dead cells in both horse and donkey embryos ranged from 2.2% to 14.1% after vitrification, which is lower than reported by others [10,12,13,[18][19][20]. Our results show that cryopreservation increased cell death in horse and donkey embryos, but no differences were noted between procedures, devices or media.…”

“…3 Articles have been published that compare slow-cooled procedures to vitrification procedures. Moussa et al (18) indicated that when equine embryos were frozen using slowcooled or open-pulled straw (OPS) vitrification, there was no significant difference in the percentage of dead blastomeres per embryo. Stehlik et al (19) froze day 5 human blastocysts using a slow-cooled or a vitrification method.…”

“…Sin embargo, la recuperación de embriones se realiza comúnmente entre los días 7 y 8, debido a que hay una mayor tasa de recuperación comparada con aquellos recuperados al día 6 (22). Se ha reportado adicionalmente que se pueden lograr mejores tasas de supervivencia posterior a la criopreservación cuando los embriones son colectados hacia el día 6, posiblemente porque no poseen la cáp-sula (glicoproteína mucina) y su tamaño es menor (23).…”

“…En el presente estudio se realizaron chequeos reproductivos por medio de palpación rectal y ultrasonografía cada 6 h; se evaluó el tamaño de los folículos hasta el momento de la ovulación considerada el día 0. Posteriormente, las colectas de los embriones fueron realizadas entre las 144 y las 156 h postovulación, lo que llevó a obtener una tasa de recuperación del 64,8 %, similar a las obtenidas por Vanderwall (24) y Moussa y colaboradores (22), quienes reportaron entre un 50 y un 63 % de recuperación.…”
