In a 2006 interview, Ekstein said that while four of his first five children died of Tay-Sachs disease, none of his children born subsequent to the founding of Dor Yeshorim suffered the condition.[Leiman, Yehoshua. "Trailblazer in Genetics for the Jewish World and Beyond". ''Personal Glimpses'', supplement to ''Hamodia'', Pesach 5766 (April 2006), page 24-27.] The same interview quotes a New York neurologist who credits the near-total disappearance of the condition from the ultra-orthodox community due to Dor Yeshorim's involvement.
In 2005, a subsidiary of Dor Yeshorim called Kehila Cord was created for the collection and storing of umbilical cord blood.
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 shidduch

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 Moshe Dovid Tendler, a professor of medical ethics at Yeshiva University

The question arises, when do you stop? There are close to 90 omozygousgenes you wouldn’t want to have. Will this lead to people showing each other computer print outs of their genetic conditions? We’ll never get married.

, said that "I think Dor Yeshorim performs a tremendous service...screening is a wonderful thing to do, and if you can avoid the birth of a potentially lethally affected child, that is a good thing."
Dor Yeshorim has been criticised for withholding patient results, for declining to publish its financial records and for not testing anyone who has already been tested elsewhere, by Geoffrey Alderman, who says that Dor Yeshorim fails some fundamental tests itself. Critics including the Association for the Prevention of Jewish Genetic Diseases, have described Dor Yeshorim in the UK as a "Wedding tax".
Dor Yeshorim was also criticised for allegedly seeking to convince the Jewish community it must, for “religious reasons”, use its service, by circulating a letter from Bezalel Rakow. 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.
