Neural substrates of sexual arousal in heterosexual males: event-related fMRI investigation
TLDR
These results suggested that the event-related paradigm is better at detecting the neural activity of the brain regions, which tend to appear suddenly, but disappear soon.
The role of left superior parietal lobe in male sexual behavior: dynamics of distinct components revealed by FMRI.
TLDR
The results suggest that the left superior parietal lobe plays a crucial role in inhibition of sexual response, among regions more active in patient group, and a high monitoring of the internal body representation is suggested.
Time-Course Analysis of the Neuroanatomical Correlates of Sexual Arousal Evoked by Erotic Video Stimuli in Healthy Males
TLDR
The results illustrate the spatiotemporal activation patterns of the key brain regions across the three stages of visual sexual arousal.
Hypothalamus, sexual arousal and psychosexual identity in human males: a functional magnetic resonance imaging study
TLDR
Results suggest that, in male subjects, inter‐individual differences in the DSI are strongly correlated with blood flow to the bilateral hypothalamus, a dimorphic brain region deeply implicated in instinctual drives including reproduction.
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.
Human brain activation during sexual stimulation of the penis
TLDR
The concept that during sexual performance the salience of the stimulus, represented by activation of the insula and SII, is of greater significance than the exact location of the stimuli, encoded in SI, is put forward.
A quantitative meta-analysis on cue-induced male sexual arousal.
TLDR
This is the first quantitative meta-analysis on sexual cue reactivity and identifies a neural network consisting of cognitive (parietal cortex, ACC, thalamus, insula), emotional, emotional, motivational, and physiological components constituting a core circuit of male sexual arousal in humans.
Neural pathways in processing of sexual arousal: a dynamic causal modeling study.
TLDR
A dynamic causal model of the brain processes mediating the cognitive, emotional, motivational and physiological factors of human male sexual arousal is suggested and has significant implications for the neuropsychology of male sexuality.

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.
Neuroanatomical Correlates of Visually Evoked Sexual Arousal in Human Males
TLDR
PET identified brain regions whose activation was correlated with visually evoked sexual arousal in males, and activation of some of these areas was positively correlated with plasma testosterone levels.
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.
Cerebral Activation Associated with Sexual Arousal in Response to a Pornographic Clip: A 15O–H2O PET Study in Heterosexual Men
TLDR
Sexual arousal was mainly associated with activation of bilateral, predominantly right, inferoposterior extrastriate cortices, of the right inferolateral prefrontal cortex and of the midbrain, and that was discussed in the light of current theories concerning selective attention, "mind reading" and mirroring, reinforcement of pleasurable stimuli, and penile erection.
Brain processing of visual sexual stimuli in healthy men: a functional magnetic resonance imaging study
Brain Activation during Human Male Ejaculation
TLDR
Insight is provided into which regions in the human brain play a primary role in ejaculation, and the results might have important implications for understanding of how human ejaculation is brought about, and for the ability to improve sexual function and satisfaction in men.
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.
