Start Connecting

The California Cryobank® Sibling Registry is a free, optional resource that helps donor conceived individuals and donor recipients connect with other donor conceived siblings who were conceived using the same California Cryobank donor.

Once you join the registry, you’ll be given access to help you discover siblings from your same donor. And, if you so choose, you’ll also have the opportunity to reach out to those sibling matches, or even share your own information with others who may be trying to connect with you.

Who Can Participate?

Participation in the California Cryobank Sibling Registry is, of course, completely optional. The registry is open to anyone using a California Cryobank donor who has notified us of a pregnancy. Donor conceived individuals (over 18) are also invited to participate, but we ask that parents carefully monitor the use of the site by any children who are under 18. In addition to California Cryobank donors, we also have some client and donor files from USC/PTI (Procreative Technologies) which we acquired in 1997. If you have any questions about USC/PTI donors, please contact us.

By participating in the California Cryobank Sibling Registry, you are agreeing to and must comply with the Terms of Use. Out of respect for the privacy of our families and donors, California Cryobank donors are not eligible to participate.

Levels of Participation

We understand that not everyone will feel comfortable sharing their personal information with other families. That’s why we’ve included several ways to participate in the California Cryobank Sibling Registry. Some individuals may choose to simply view other posts in their Donor Sibling Group without sharing any personal information; others may be interested in posting their own Sibling Listings and interacting further with other families related to their donor.

Regardless, your confidentiality will always be protected and only the information you want to disclose will be disclosed.

Here are the levels of participation from which you can choose:

Please note: To safeguard the privacy of our families, any access or interaction you choose is limited to your individual Donor Sibling Group only.

Guidelines for Participation in the Sibling Registry Bulletin Board

Rather than a universal forum for all California Cryobank Sibling Registry users, your Bulletin Board offers access only to those associated with your particular donor.

You’re encouraged to visit your Bulletin Board to view, share, or exchange information with other potential siblings — to enrich this resource to its fullest. We only ask that every participant is respectful of others and of the family-friendly spirit behind this forum. To that end, all messages posted on our Bulletin Board will be regularly reviewed by California Cryobank, and any person who is found to be harassing or in conflict with other participants risks having their access to the Sibling Registry restricted. For a list of additional restrictions, please refer to the Terms of Use.

We look forward to helping you connect with other Cryobank families! Please feel free to contact us if you have any questions.

Please Note: Messages from our old Sibling Registry will not display unless the member who posted the message activates their account on our new website.
