Introduction Sexual pleasure is fundamental for the maintenance of health and well-being, but it may be adversely affected by medical and psychosocial conditions. Many patients only feel that their health is fully restored after they resume normal sexual activities. Any discussion of sexuality in a doctor's office is typically limited, mainly because of a lack of models or protocols available t...

Campus response to sexual violence is increasingly governed by federal law and administrative guidance such as the 1972 Title IX, the 2011 Dear Colleague Letter (DCL), and the 2013 Violence Against Women Act. Educational institutions are directed to expand disciplinary responses and establish coordinated action to eliminate sexual violence and remedy its effects. Compliance fosters a quasi-crim...

A theoretical model of dual control of male sexual response is considered, based on the balancing of central excitation and inhibition, with individuals varying in their propensity for both sexual excitation and inhibition of sexual response. A questionnaire method for measuring propensities for sexual excitation and inhibition has been developed (SIS/SES questionnaire), resulting in one excita...

Sperm competition occurs when the sperm of multiple males concurrently occupy the reproductive tract of a female and compete to fertilize an egg. We used a questionnaire to investigate psychological responses to the risk of sperm competition for 237 men in committed, sexual relationships. As predicted, a man who spends a greater (relative to a man who spends a lesser) proportion of time apart f...

The consequences of risky sexual behavior are of public concern. Adolescents contribute disproportionately to negative consequences of risky sexual behavior. However, no research has examined the neural correlates of impulse control and real-world engagement in risky sexual behavior in this population. The aim of the present study was to examine this question. Twenty sexually active adolescents...

INTRODUCTION Few studies have examined how sexual arousal influences healthy premenopausal women's hormones, limiting our understanding of basic physiology and our ability to transfer knowledge from clinical and nonhuman populations. AIM To examine how sexual arousal and steroid hormones (testosterone [T], cortisol [C], estradiol [E]) were linked, to see whether hormone levels influenced and/...

In response to this insightful editorial, we wish to provide commentary that seeks to highlight recent successes and illuminate the often unspoken hurdles at the intersections of culture, politics, and taboo. We focus on sexual transmission and draw examples from Lebanon, where the pursuit of data in quality and quantity is teaching us lessons about the way forward and where we are experiencing...

Psychophysiological studies of sexuality have largely, if not completely, ignored issues of individual variability in responsiveness. Most of the research published in this area involves the comparison of subject groups, experimental conditions, or treatments. The few attempts to evaluate individual variability have been restricted to the measurement of sexual attitudes and behavioral tendencie...
