Will the recipients know who I am?
Sperm donors are represented online with a donor profile under a fictious name or number. The donor profile helps future parents decide which donor to use but does not include any identifying information such as your name or contact info, and Cryos will never reveal your name to the recipients.
Only if you decide to become an ID Release Donor, children born from your donations can contact Cryos after they turn 18 to receive identifying information about you.
