Abstract
Conventional in vitro fertilization is poorly successful with equine gametes. Although stallion spermatozoa bind to the zona pellucida in vitro, they fail to acrosome react and cannot therefore penetrate into the perivitelline space. Failed sperm penetration most likely relates to the absence in in vitro fertilization media of essential molecules required to fully support stallion sperm capacitation. In vivo, the oviductal lumen provides an environment that appropriately regulates interactions between the gametes and promotes fertilization. Identifying the oviductal "fertilization stimulating factors" would enormously benefit the development of equine in vitro fertilization media. This review focuses on the current understanding of equine sperm-oviduct interactions, which may hold essential clues to achieving successful in vitro fertilization with equine gametes.
