We utilized contrast enhanced magnetic resonance imaging (MRI) to delineate the anatomy of the female genital and pelvic organs during sexual arousal. Eleven healthy pre-menopausal women and eight healthy post-menopausal women underwent MRI of the pelvis while watching an erotic video. A 1.5 Tesla MR system was used to produce T1-weighted images following administration of MS-325, a gadolinium-...

Evidence relevant to a potential diagnosis of Paraphilic Coercive Disorder is reviewed. Salient cues indicating that their partner is feeling coerced normally at least partially inhibit male sexual arousal while cues indicating mutual interest heighten arousal. However, for a minority of males, this pattern reverses with salient coercion cues leading to heightened arousal. This unusual pattern ...

This investigation was designed to examine the effects of acute exercise on physiological and subjective sexual arousal in women. In Experiment 1, Ss participated in two experimental sessions in which they viewed a neutral film followed by an erotic film. In one of these sessions, Ss were exposed to 20 min of intense exercise prior to viewing the films. Subjective sexual arousal was measured wi...

METHOD Five hundred and eighty six adult male sexual offenders were assessed between 19...

The current study was aimed at comparing genital and subjective sexual arousal in pre- and postmenopausal women and exploring the effects of heightened sympathetic nervous system (SNS) activity on these parameters. Seventy-one women (25 young and premenopausal, 25 postmenopausal, and 21 age-matched premenopausal women) participated in two counterbalanced sessions consisting of genital arousal a...

This study was performed to clarify the sexual orientation in a 19-year-old homosexual male and a 20-year-old homosexual female by using a functional magnetic resonance imaging (fMRI) with viewing male and female erotic nude pictures. The sex hormone levels of the homosexual male and female were in the normal range of healthy heterosexual males and females, respectively. In both homosexuals mor...

Research indicates hysterectomy surgery may adversely affect the pelvic autonomic nerves and autonomic mechanisms are integral to the sexual arousal response in women. This study explored the possibility that women who undergo hysterectomy may experience an impaired vasocongestive response to erotic stimulation. Thirty-two women with a history of benign uterine fibroids who had ( n = 15) or had...
