What does it mean that a sperm donor is in quarantine or permanently blocked?

In our Sperm Donor Search you might encounter a donor profile that is marked with a special alert (Condition). This is a precaution that is put into place when Cryos receives a Report of Condition that might be related to the donor.

If we receive a Report of Condition, our Genetics team will handle it immediately and start an investigation. The purpose of the investigation is to assess if the disease could or could not be related to the donor. In some cases, our Genetics team will conclude that the report can be rejected, and that no further actions are necessary. This is the case when the Genetics team assesses that the disease is not related to the donor or that the risk of recurrence in half siblings is not significantly elevated. In other cases, the report of condition requires further investigation, and the donor will then be put in quarantine, as a temporary precaution, while further investigation is carried out. For safety reasons, Cryos will not deliver any sperm straws from a donor who is in quarantine.  

Eventually, the conclusion will either be that the report of condition can be rejected, or that the donor’s straws must be permanently blocked. Donor straws will be permanently blocked if our Genetics team assesses that the condition is related to the donor, or if it cannot be ruled out whether it is related to the sperm donor.
