Sperm Cryopreservation System
Controlled-Rate Freezing and Vitrification for Spermatozoa
Specialized system for cryopreservation of spermatozoa from multiple species
Purpose
Specialized system for cryopreservation of spermatozoa from multiple species
Context
Child of L2-GEN-EMBR
Principles
- ▸Controlled-rate freezing (-1 to -10 C/min) is standard for most mammalian sperm
- ▸Glycerol or egg yolk-based extenders protect sperm during freezing
- ▸Straw or pellet format enables efficient storage and individual sample retrieval
- ▸Post-thaw motility assessment validates cryopreservation success
Typical implementations
- ▸IMV Technologies CBS straw cryopreservation system
- ▸Minitube SpermVision automated analysis
- ▸San Diego Zoo Wildlife Alliance sperm banking protocols (1000+ species)
Lunar considerations
- ▸Species-specific protocols needed - no universal sperm freezing method exists
- ▸Avian and reptile sperm particularly challenging to cryopreserve
- ▸Fish sperm cryopreservation well-established for aquaculture species
