Genetics and the Heart: Why Dor Yeshorim Should Happen Before the First Date
Why early screening protects the heart, privacy, and the next generation

One of the most painful situations in shidduchim is a breakup at a late stage because of genetic incompatibility. That is why shadchanim and rabbis insist that the screening be done as soon as both sides agree to a first date.
Protection from heartbreak
Do not wait for attachment to grow. If a couple has already begun dating and an emotional bond forms, learning about incompatibility can feel devastating.
Responsibility toward the next generation. Doing the screening early is not coldness, but care for the future home and children.
Absolute confidentiality. If the test shows incompatibility, it should not be discussed with anyone beyond the two sides. Such incompatibility does not mean anyone is ill or defective.
The deeper purpose. Both people may be able to build healthy families with other partners. The system simply helps prevent avoidable pain.
