What Are Donor Sibling Registries?

Donor sibling registries are websites for individuals that have used an egg or sperm donor who want to  search for donors or siblings.

For sperm donors, there are only a few bank-specific registries and one national donor registry, the "Donor Sibling Registry."

The Donor Sibling Registry is the only national registry in the U.S. Founded by Wendy Kramer and her donor-conceived son Ryan, the registry was created to connect donors and siblings searching for each other.

California Cryobank also has a donor sibling registry, but it is only for clients who have used their sperm donors.
