Heterosexual men’s pupillary responses to stimuli depicting cisgender males, cisgender females, and gynandromorphs

Abstract

Gynandromorphophilia is the sexual attraction and arousal to feminine individuals assigned male at birth, who may or may not have breasts, and who retain their penises. Previous research has suggested that some capacity for gynandromorphophilia may characterize all males who are gynephilic (i.e., sexually attracted and aroused to adult cisgender females). This study examined Canadian cisgender gynephilic men’s (n = 65) pupillary responses and subjective ratings of sexual arousal when presented with nude images of cisgender males, cisgender females, and gynandromorphs with, and without, breasts. Subjective arousal to cisgender females was highest, followed by subjective arousal to gynandromorphs with breasts, gynandromorphs without breasts and cisgender males. However, subjective arousal to gynandromorphs without breasts and to cisgender males did not differ significantly. Participants’ pupils dilated more to images of cisgender females than to all other stimulus categories. Participants’ pupils dilated more to gynandromorphs with breasts than to cisgender males, but pupillary response to gynandromorphs without breasts and cisgender males did not differ significantly. If the capacity for gynandromorphophilic attraction is a cross-culturally invariant aspect of male gynephilia, then these data suggest that this capacity may only extend to gynandromorphs with breasts and not gynandromorphs without breasts.
