Who We Are

The Donor Sibling Registry (DSR) was created in September 2000 by Wendy Kramer and her son, Ryan. Certain that other donor offspring would have the same curiosity as Ryan about his genetic origins — yet also knowing that sadly, no public outlet existed for mutual consent contact between people born from anonymous sperm or egg donation — this site was started as the logical next step to making those connections.

In addition to the registered members, several thousand people check the site regularly. The DSR averages more than 17,000 unique visitors to the site each month and is a worldwide organization, matching people in Australia, Austria, Belgium, Bolivia, Brazil, Canada, Cayman Islands, Chile, China, Cyprus, Denmark, Dominican Republic, Estonia, Finland, France, Germany, Greece, Haiti, Hong Kong, Iceland, Ireland, Israel, Italy, Japan, Kenya, Liechtenstein, Luxembourg, Malta, Mexico, New Zealand, Norway, Philippines, Puerto Rico, Russia, S. Africa, S. Korea, Spain, Sweden, Switzerland, Taiwan, Tanzania, The Netherlands, Turkey, the USA, and the UK.

A large community of people, just like you

The Donor Sibling Registry was created to connect people, and we love it when members share their stories with us.

How to Use the Donor Sibling Registry

First, join the DSR and add your posting. (It's free!) Then, upgrade to a paid membership ($99 for one year or $199 for a permanent membership) so that you can connect with your matches and/or make yourself available to be found by them. Once you've added your posting, you'll then get automatic DSR emails when you have a new match, when a DSR member has sent you a message, and when anyone who has posted for your donor adds information to the medical page that's only shared among your matches.

Just because you don't see someone already posted with your donor number doesn't mean you don't have a match. Many people are out there watching the site and waiting to post until they see another posting for their donor — so be the first!

Make sure to always have up-to-date contact information on the DSR. If you forget your username or password, the site can help you recover them. (Please, never sign up with a second username.)

If you're having trouble, visit our Site Help page or contact us for assistance.
