educating, connecting and supporting donor families

 WELCOME!

The Donor Sibling Registry was created in September 2000 by Wendy Kramer (me) and my 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 exists for mutual consent contact between people born from anonymous sperm donation, we started this site as the logical next step to making those connections!  Active membership (both paying and non paying members) in the Donor Sibling Registry is currently at 12580 with matches between more than 5091 half-siblings (and/or donors) facilitated.

Total number of registrants, including children, is currently at 19791.  Several thousand more  check the site regularly, but are not ready to post their information. So far in 2008 (from January through  April) we have had 51,400 unique visitors to the site.  The DSR is a worldwide organization, matching people  in the US, Denmark, England, Canada, Australia, Bolivia, Brazil, Finland, France, Germany, Hong Kong, Israel, Korea, New Zealand, Norway, S. Africa, Sweden and Switzerland.

The focus of the Donor Sibling Registry (DSR) is to assist individuals conceived as a result of sperm, egg or embryo donation who are seeking to make mutually desired contact with others with whom they share genetic ties. This may include:

  • Their own or their child's half-siblings, or
  • their own or their child's sperm or egg donor, or
  • their own genetic offspring.

The DSR fully supports openness, honesty and the acknowledgement of these family connections. We realize, however, that some folks may want to remain anonymous while sharing important medical or genetic information with their fellow "donor families".  For these people, we suggest using a throw away untraceable email address.

Egg, sperm or embryo donors who are willing to have contact with the children born as a result of their donations are VERY WELCOME! Even if you do not know your donor number, it is still possible to search and be found. Contact Wendy if you need help. wendy.kramer@yahoo.com

Please feel free to "Browse by Clinic," and sign up and post a listing if you are comfortable. If you don't see any matches listed, remember: you can't be found unless you list yourself, and there are many people - interested but not yet posted - who may be your match.

Trying to Decide Which Sperm Bank to Use?  I can give my impressions as to which sperm banks I think are more receptive to the needs of donor families.  For members only, you can view the clinic experiences and reviews by DSR members on the "Resources" page.

If you have questions about donor sibling issues, please consult our FAQ, and for complete instructions on joining and using the DSR, please consult the How Do I...? section.

The Donor Sibling Registry is a recognized 501(c)(3) non-profit organization.

"...we can always make a difference if we muster the courage to think critically, to care for others, and to sustain a hope so that we can organize and mobilize with one another to bring power and pressure to bear on the prevailing status quo." - Cornel West
