Men exhibit much higher levels of genital and subjective arousal to sexual stimuli containing their preferred sex than they do to stimuli containing only the nonpreferred sex. This study used event-related functional magnetic resonance imaging to investigate how this category-specific pattern would be reflected in the brains of homosexual (n = 11) and heterosexual (n = 11) men. Comparisons of activation to preferred sexual stimuli, nonpreferred sexual stimuli, and sports stimuli revealed large…

Neural Responses to Sexual Stimuli in Heterosexual and Homosexual Men and Women: Men’s Responses Are More Specific
TLDR
The results provide the most direct evidence to date that men’s sexual arousal patterns are more gender specific than women’'s, as measured identically in men and women.
Neural Correlates of Sexual Orientation in Heterosexual, Bisexual, and Homosexual Men
Studies of subjective and genital sexual arousal in monosexual (i.e. heterosexual and homosexual) men have repeatedly found that erotic stimuli depicting men’s preferred sex produce strong responses,
Neural Correlates of Sexual Orientation in Heterosexual, Bisexual, and Homosexual Women
TLDR
It is found that homosexual women’s subjective and neural responses reflected greater bias towards female stimuli, compared with bisexual and heterosexual women, whose responses did not significantly differ.
Haemodynamic Brain Response to Visual Sexual Stimuli is Different between Homosexual and Heterosexual Men
TLDR
Viewing sexual stimuli induced significantly different brain activations, most of which had the characteristics of cognitive processes, suggesting that different cognitive patterns may be the major cause of different subjective responses to sexual stimuli between heterosexual and homosexual men.
Neural activation toward erotic stimuli in homosexual and heterosexual males.
TLDR
Results suggest that a widespread neural network is activated by highly sexually arousing visual stimuli, and a partly distinct network of structures underlies sexual and general arousal effects.
Neural substrates of sexual arousal are not sex dependent
TLDR
A thorough statistical review of significant neuroimaging studies offers strong quantitative evidence that the neuronal response to visual sexual stimuli, contrary to the widely accepted view, is independent of biological sex.
Neural circuits of disgust induced by sexual stimuli in homosexual and heterosexual men: an fMRI study.
Neural Substrates of Sexual Desire in Individuals with Problematic Hypersexual Behavior
TLDR
Investigating the neural correlates of sexual desire with event-related functional magnetic resonance imaging (fMRI) will help to characterize the behaviors and associated neural mechanisms of individuals with PHB.

A Sex Difference in the Specificity of Sexual Arousal
TLDR
The results for females are unlikely to be explained by ascertainment biases, and suggest that sexual arousal patterns play fundamentally different roles in male and female sexuality.
Men and women differ in amygdala response to visual sexual stimuli
TLDR
It is shown that the amygdala and hypothalamus are more strongly activated in men than in women when viewing identical sexual stimuli, and the human amygdala may also mediate the reportedly greater role of visual stimuli in male sexual behavior, paralleling prior animal findings.
Brain activation and sexual arousal in healthy, heterosexual males.
TLDR
This study demonstrates the feasibility of examining brain activation/sexual response relationships in an fMRI environment and reveals a number of brain structures whose activation is time-locked to sexual arousal.
Neurohormonal functioning and sexual orientation: a theory of homosexuality-heterosexuality.
TLDR
Evidence indicating that the process of determining human sexual orientation is fundamentally the same in all mammals is reviewed, and a theory of how the entire spectrum of humanSexual orientation is determined is proposed.
Sexual Arousal Patterns of Bisexual Men
TLDR
B bisexual men did not have strong genital arousal to both male and female sexual stimuli, and most bisexual men appeared homosexual with respect to genital arousal, although some appeared heterosexual.
Areas of brain activation in males and females during viewing of erotic film excerpts
TLDR
The findings reveal the existence of similarities and dissimilarities in the way the brain of both genders responds to erotic stimuli and suggest that the greater SA generally experienced by men, when viewing erotica, may be related to the functional gender difference found here with respect to the hypothalamus.
