In the book the author looks at transsexualism as a behavioral addiction, much like a sex addiction, Internet addiction or gambling addiction, which is caused by a faulty reward system in the human brain. The author further reports that the medications that effectively treat behavioral addictions show good results in treating transsexualism. The author further shows that if the medical community were to treat transsexualism in the context of a behavioral addiction in lieu of a gender identity disorder, that transsexualism as it is known today would be virtually eradicated within one generation.
