Genetic sexual attraction (GSA) is a term that describes the phenomenon of sexual attraction between close relatives, such as siblings, first and second cousins or a parent and offspring, who first meet as adults.[1]
The term GSA was first coined in the US in the late 1980s by Barbara Gonyo, the founder of Truth Seekers In Adoption, a Chicago-based support group for adoptees and their new-found relatives.[2]
GSA is presumed to occur as a consequence of adoption, when the adopted children knowingly or unknowingly encounter biological relatives. Although this is a rare consequence of adoptive reunions, the large number of adoptive reunions in recent years means that a larger number of people (about half) are affected.[3] If a sexual relationship is entered, it is known as incest, and may be distressing to both parties (see incest taboo).
GSA is rare between people raised together in early childhood due to a reverse sexual imprinting known as the Westermarck effect, which desensitizes them to later close sexual attraction; it is hypothesized that this effect evolved to prevent inbreeding.
