Technological advances have permitted sexological questions to be addressed with studies using behavioral genetics, neuroimaging, and large-scale Internet-based surveys. Sexology is a regulated profession in some jurisdictions. In Quebec, sexologists must be members of the Ordre professionnel des sexologues du Québec. They are one of the professions eligible to receive psychotherapy permits from the Ordre des psychologues du Québec.
