Donor Sibling Registry User Policy

Terms and Conditions of Use (Please, read at least the first 7 bullet points!)

  • Refund Policy: The DSR WILL NOT REFUND MEMBERSHIPS. If you join the DSR, use our services, and then fraudulently put in for a chargeback, this will be noted on the face of your posting and reported to your matches.

  • DSR Username Policy: Please do not use your first/last name or email address as a username, or share it anywhere on your personal details page or anywhere on your posting.

  • You must be at least 18 years old to enter the DSR website as a paying member. By agreeing to this User Policy, you are declaring that you are at least 18 years old.

  • Please make sure to post under the originating sperm bank, not your local clinic. The sperm banks ship to hundreds of small clinics around the world, so it is important to post under the facility where the donor actually donated. Please don't add a second posting under your local clinic, as it's not necessary.

  • Getting in Contact: Once you are a member and have added your posting, you can send an email by clicking on a match's username next to their posting. REMEMBER: After entering your personal information you must "Add a New Posting." 

  • No sharing of DSR Accounts: Your account is for you and your immediate family only, not to be shared with others. If you are caught sharing a username, or posting for, or contacting members for non-DSR families, your membership will be suspended until full payment from both parties is received.

  • NOTICE TO MEDIA, RESEARCHERS, DSR COPYCAT GROUPS, LAWYERS, AND SPERM BANKS/EGG CLINICS: It has come to our attention that some members of the media, some researchers, people looking to replicate the DSR's work, and some sperm banks/clinics have been using our site to contact members. You may not use the DSR site to collect personal information or to message our members. Anyone caught on the DSR site from the media, researchers, or sperm banks/egg clinics will be immediately removed and your membership fee will be considered a donation. Anyone mass messaging DSR members for any reason besides their own connections will have their membership suspended and DSR members will be alerted via a message from us on the face of your posting.

  • NOTICE TO MEMBERS: If you feel your privacy has been invaded by unsolicited contact from a member of the media or anyone else, please let us know by sending an email to When connecting with donors, if you have a donor profile, keep some information off of your posting, so that you can have the donor verify that they are actually your donor.

  • Sibling Searchers: Individuals (parents and over 18 donor-conceived people) listed on the DSR are interested in exchanging information regarding half-brothers and half-sisters conceived through donor insemination or donor eggs, and frequently info about the donor as well. Donors used are posted by cryobank of origin and identification number, where known; otherwise a description of the circumstances and donor characteristics is shown. Donor-conceived people over 18 years of age who have listed themselves are coded by a distinct icon.

  • Donor Listings: Donors listed on the DSR are interested in exchanging information with recipients and/or their genetic offspring, as mutually deemed age-appropriate. These listings are also noted by an identifiable icon on the DSR: one for Sperm Donors and one for Egg Donors. Often, cryobanks and fertility clinics will not inform a donor of his/her identification number, thus only a physical description can be matched. Donor recipients are thus encouraged to list their donor's description.

  • Successful Sibling-to-Sibling Matches: These are color-coded in pale yellow.

  • Successful Donor-to-Offspring Matches: These are color-coded in orange.

  • Non-Discrimination Policy: The Donor Sibling Registry (DSR) believes that diversity is a fundamental value. We believe that greater diversity will enhance the quality of all families and communities and will enrich the understanding between people. The DSR provides equal opportunity for all its members, volunteers, employees, and applicants for employment regardless of race, color, creed, religion, national origin, ancestry, citizenship, sexual orientation, gender identity, disability, veteran status, age, gender, marital status, height, and weight. The DSR expects all of its members, volunteers, and employees to join together to develop a community where everyone values individual and group differences and respects the perspectives of others. Please, do not register here and make yourself willing to initiate contact if you are not aligned with our policy.

  • Privacy/Confidentiality/GDPR Compliance: The only information about its members that is stored by the DSR are the names, contact information, and posting information that our members provide to us, which are necessary for us to fulfill our mission. No one can see any personal information about another on the site (unless you send that information to another yourself via our messaging system). We have never, and will never, share or sell our membership information with any third party or entity. If you request to be removed from the DSR, all of your contact information will be removed at that time. We use to process membership payments and house no credit card information ourselves. The DSR has an SSL certificate, meaning that our website uses HTTPS to send data over an encrypted connection. You have the right to exercise your data protection rights, including the right to request that the DSR deletes your contact information. You have the right to opt out of receiving the DSR's mass mailings (that option is included on each mailing), but you will still receive other DSR communications. Our website and all its databases are hosted by Amazon Web Services (GDPR compliant).

  • Disclaimer: This registry is intended strictly for informational purposes and is neither endorsed nor supported by any individual or organization. Please note that while access to the Donor Sibling Registry list and database is restricted to individuals over 18 years of age, it is up to each and every parent to supervise and monitor their child's use of the Internet. Each member is responsible for making sure that the donor number they list is accurate. We recommend DNA testing for those matches who are not 100% certain of their donor number. We do not guarantee any matches, because we have no verification system in place with the sperm bank industry.

The DSR does not assume and hereby disclaims any liability for loss or damage caused by using the contents or from any errors or omissions resulting from negligence, accident, or other causes.

  • Emails: Rarely, the DSR will send out a mass email to invite members to participate in research, alert members about a big DSR media event, or provide an important update regarding website security. Additionally, quarterly newsletters may be emailed out. Please let us know if you wish to opt out of these emails.
