Donor Sperm Bank Storage: Keeping Quarantine, Release and Allocation Under Control

Most of the work in a donor sperm bank happens after the freeze. Every straw has to be tracked from donation to quarantine, from quarantine to release, and from release to a named clinic and family. When that chain is clear, the bank can answer any question an inspector or a clinic asks. When it is not, staff spend their time reconstructing records.

Quarantine needs its own space

Under rules retained in UK law, sperm from anyone other than a partner is quarantined for a minimum of 180 days before the donor is retested, with an exception where NAT testing is used. Keeping quarantine material in dedicated vessels, or at least in clearly marked canisters with their own colour scheme, makes it physically hard to release a straw too early.

Release as a witnessed move

When repeat results come back clear, release should be a recorded step: results checked against the donor record, straws moved from quarantine storage to release storage, and the inventory updated in the same session.

Straws that carry their own history

Sealed high security straws suit long term storage and shipping. Every straw needs a permanent identifier written in cryogenic ink or printed on low shrink labels, and each donor's straws should sit together in their own visotubes inside goblets or canisters.

Allocation within the family limit

In the UK a donor can be used to create children in up to ten families. A bank supplying several clinics needs a clear allocation record of which clinics and families hold each donor's straws, so it can stop releasing to new families once the limit is reached.

Shipping to clinics

Released straws travel in charged dry shippers with temperature data loggers, and each consignment carries a straw list that matches the allocation record.
