Sperm Cryorecovery Service

If you used our Sperm Cryopreservation Service or our Sperm Cryo Kit to cryopreserve your strains, we can produce live mice for you in as little as nine weeks.*

Key benefits

  • Recovery completed within nine to 12 weeks
  • All mice produced in room G200 are specified and opportunistic pathogen free (SOPF) and shipped with a comprehensive health report


  • Protocols developed by JAX, pioneers in cryopreservation technology
  • Standard recovery yields an average of 10 or more pups
  • Larger cohorts can be economically produced from strains with high fertilization rates through our Speed Expansion Service
  • Cryopreserved embryos can be produced from cryopreserved sperm


  • Standard Recovery for most strains: $1,900 (varies with background, fertilization rate, and quantity desired)

* If you need to have cryopreserved mouse sperm recovered that was not frozen by JAX or our Sperm Cryo Kit, please contact us and we will evaluate it for feasibility and cost.
