Springwise:
‘Personal chemistry’ has long been a blanket term for all the things that make people compatible (or not), but until recently only science fiction films like Code 46 have taken the notion literally. As of December, however, Boston-based ScientificMatch is using DNA to assess personal chemistry for dating purposes.
ScientificMatch uses three components to match up singles through its dating service: personal chemistry, values and personal preferences. While the latter two are assessed via questionnaire, personal chemistry matching is done via DNA analysis. The immune system is what has been found to affect sexual compatibility, with people tending to prefer those whose immune systems are different from their own. The benefits of well-matched immune systems, according to research cited by ScientificMatch, include a more satisfying sex life, increased faithfulness, higher fertility and healthier children.
