Key Factors
Important considerations when choosing sperm or embryo cryopreservation:
| Factor | Sperm | Embryo |
|---|---|---|
| Cost to Freeze | Low | Medium to High |
| Cost to Recover | Medium to High | Low |
| Time to Freeze | Low | Medium to High |
| Time to Recover | Medium | Low |
| Reliability | High | High |
| Genotype Produced | Heterozygous | Heterozygous/Homozygous |
| Advantages | Only requires 2 males | Can be quickly rederived |
| Limitations | Pups from IVF will be heterozygous | Requires up to 10 males and females to maintain homozygous lines per cryopreservation event |
| Optimal Use | Strains with single mutations | Strains with multiple mutations |
Cryopreservation Benefits
When your research depends on unique, high‑value mouse models, cryopreservation gives you peace of mind and the freedom to focus on discovery instead of colony maintenance.
Why researchers choose cryopreservation:
Unmatched protection for irreplaceable lines
Safeguard your strains against unforeseen events—from facility emergencies to breeding interruptions.Guaranteed genetic integrity
Lock in the exact genetics you rely on and eliminate the risk of drift over time.Stronger biosecurity for your colonies
Keep your models safe from pathogens, outbreaks, and other health-related disruptions.Continuity you can count on
Access your lines whenever you need them, even if live breeding slows or stops.Smarter, simpler distribution
Ship frozen embryos or sperm—reducing stress on animals and streamlining logistics.Significant cost savings
Lower housing, husbandry, and genotyping expenses.Future‑ready research planning
Archive lines now and bring them back exactly when projects demand them.More efficient colony management
Avoid overcrowding and maintain lean, purposeful colonies.
