Abstract:
Cryopreservation is the procedure that allows preserving cells, including gametes, for long time periods while maintaining their functionality, through the use of cryogenic temperature. Currently, sperm cryopreservation is a crucial-assisted reproductive biotechnology in pigs since it is the only effective and efficient method for long-term preservation of boar fertility. Here, we describe a two-step cryopreservation protocol for boar sperm using lactose-egg yolk and glycerol-based extenders.
