However, the conclusions of the pathogen stress theory are controversial, since different authors suggest distinct interpretations (Hackman and Hruschka, 2013; Hruschka and Henrich, 2013; Hruschka and Hackman, 2014); also see Sexually Transmitted Diseases and Beauty Premium, Impulsivity and Personality Disorders section.

These findings support the possibility that the higher level of testosterone in infected men could be the consequence of the infection and, ultimately, the result of the parasites host manipulation to transmit easily by sexual intercourse.
