Paraphilic syndromes, of which there are at least 40, are known legally as perversions and on the street as kinky and bizarre sex. Paraphilia accounts for a very high proportion of sex-offending that is prosecuted as criminal. A new treatment which combines a hormonal antiandrogen with sexological counseling therapy is becoming widely adopted in America and Europe. The treatment is available also to noncriminal paraphiliacs whose syndrome is a source of interpersonal suffering and crisis.
