Who We Are

Wendy and Ryan Kramer

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 16,000 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, 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.

How to Use the Donor Sibling Registry

To Find Family:  You must add your posting to the DSR before contacting any other member. After you add your posting, you will then get automatic DSR emails when you have a match, when a DSR member has sent you a message, and when anyone who has used your donor adds information to the medical page that is specifically for your donor. Just because you don't see someone already listed with your donor number, doesn't mean you don't have a match. Many people are out there waiting to post until they see another posting for their donor - so be the first!

Make sure to always have an up-to-date email address listed on the DSR and please note: you must add your posting before contacting any DSR member.

And please, never sign up with a second username- either the site can send you your password, or just email Wendy to re-set it!

My brother Jason and I have the same donor and were born 8 months apart. He found my DSR profile on New Year's Day of 2014, and we met each other in person shortly after. We felt an instant connection, and feel so lucky to have found each other. This picture is from my wedding in 2015. You can see how close we've become! All thanks to you and the DSR.
