Mhoa, dat valt wel mee hoor.
Our study confirmed the existence of specific differences in sexual behavior, desires, and preferences between Toxoplasma-infected and Toxoplasma-free subjects. The character of these changes, that is, the higher attraction to bondage, violence, and, in men, to masochism and raping supports our hypothesis about the coactivation of sex-related and fear-related medial amygdala circuits in humans. It must be stressed that the Toxoplasma infection explains only small part of the variability in BDSM-associated traits. It was shown that sensitivity of current serological tests is not ideal and that even in populations of young seronegative subjects, 5–15% individuals are, in fact, Toxoplasma infected (Flegr & Havlíček, 1999; Flegr, Hrdá, & Kodym, 2005). In older age strata, the seroprevalence of toxoplasmosis decreases (Kolbeková, Kourbatova, Novotná, Kodym, & Flegr, 2007), which suggests that the frequency of false negatives among older people is probably much higher. It could be speculated that the false negatives, that is, the subjects with the oldest infections and therefore lowest concentration of anamnestic anti-Toxoplasma antibodies, could be responsible for certain BDSM traits in seemingly Toxoplasma-free subjects. A more probable explanation, however, is that the sexual arousal by danger, fear, and so on could have a common neurophysiological mechanism (possibly the coactivation of sex-related and fear-related circuits in amygdala), however this coactivation could have various independent causes and Toxoplasma just (mis)uses this property of the mammal brain for manipulation with behavior of their intermediate hosts.
