Effect of Embryo-Recipient Synchrony on Post-ET Survival of In Vivo and In Vitro-Produced Equine Embryos

Equine embryo transfer (ET) permits a relatively large degree of ovulation asynchrony between donor and recipient mare (+1 to –4 days). However, when the embryo is more than 4 days advanced than the uterus, its development is retarded after ET [1]; conversely, pregnancy rarely results in recipients that ovulate ≥2 days before the donor [2].
