. In 2016, Dor Yeshorim received media attention when a rap video of two schoolgirls beat-boxing about their marriage prospects was shared in the Orthodox Jewish community. The organisation claimed to be "very disturbed by the whole thing" and that "...it is below our dignity as an organization to promote such a thing". Subsequently, Dor Yeshorim also issued an official statement distancing itself from the video.

The samples collected by Dor Yeshorim are anonymized; the only personal information associated with each sample is date of birth. A randomized ID number that identifies the sample is provided to the submitter. When two Dor Yeshorim clients contemplate marriage, they exchange sample ID numbers and birth dates and each contacts the organization. When both carry a gene for the same disorder, they are informed that the match is not recommended. In that case, a client can optionally contact Dor Yeshorim separately for counseling and support services. In this way, complete privacy is guaranteed; not even Dor Yeshorim employees are aware of who was found to be genetically incompatible unless the clients desire otherwise. Dor Yeshorim does not report to the clients which disease was indicated, in order to avoid "unnecessary emotional burden" and "stigmatization of families". In the context of

im, this genetic compatibility check is commonly run within the first three dates or even before the first date, to avoid disappointments and heartbreak. In the United States, testing costs range from $225 to $500. One-half of the actual testing costs is subsidized by private donors and governments. For convenience, Dor Yeshorim provides yearly testing sessions at Orthodox Jewish schools for students who are approaching marriageable age. Samples can also be provided privately.


Reception

The system has received praise and criticism from both within as well as outside the community. By March 2006, Dor Yeshorim had achieved wide support in the Orthodox Jewish community and among its leaders, and had become household name that was taken for granted. By that time, they had tested over 200,000 individuals, and had responded "incompatible" to 750 suggested matches. There has been criticism leveled against the method used by Dor Yeshorim by

Rakow was a signatory to a subsequent letter stating that "Every individual has the privilege to perform the test in a manner consistent with his desires.” In 2012, the Jewish Chronicle published a letter by a Tay–Sachs carrier, who was hurt by a Dor Yeshorim organiser's insinuation that there was stigma attached to being a Tay–Sachs carrier.
