Androphilia refers to sexual attraction and arousal to adult males, whereas gynephilia refers to sexual attraction and arousal to adult females. Male androphilia is considered one of the outstanding paradoxes of evolutionary biology because its very existence flouts our expectations concerning what constitutes an evolutionarily viable trait (Bailey & Zuk, 2009). In humans, male androphilia is heritable, as evinced by twin studies (Alanko et al., 2010; Bailey et al., 2000; Kendler et al., 2000; Långström et al., 2010), as well as research in the area of molecular genetics (Hamer et al., 1993; Mustanski et al.,2005; Sanders et al., 2015). Despite the heritability of this trait, androphilic males reproduce at far lower rates when compared to gynephilic males, if they reproduce at all, which, very often, they do not (e.g., Bell & Weinberg, 1978; King et al., 2005; Saghir & Robins, 1973; Schwartz et al., 2010).
