The investigator needs to be aware that we cannot guarantee success with all strains and that more mice and time may be necessary, leading to a higher cost for the service.
Finally, the investigator needs to be aware that while sperm cryopreservation may look enticing based on cost alone, the pricing reflects only upfront expenditure. Should the strain need to be reconstituted, the costs are generally higher, since only a haploid genome has been preserved. Sperm cryopreservation is not always the best cryopreservation option.
