“…Such treatments have included aversion 'therapy', which paired the erotic stimuli with an aversive stimulus through classical conditioning aimed at making the erotic stimuli aversive. These 'therapies' included using electric shocks (Marks & Gelder, 1967;Marks et al, 1965), nausea (Raymond, 1956), and foul odours (Junginger, 1997;Laws, 2001); however, they had limited efficacy and are understandably controversial (Krueger & Kaplan, 2002). More recently, especially in forensic settings, anti-androgens such as goserelin and cyproterone acetate have been used (Thibaut, 2012); however, these necessarily only address testosterone-induced sex drive and not the underlying causes and nature of the person's sexuality.…”
