Drawing upon a large, recent probability sample of American adults ages 18-60 (7648 men and 8090 women), we explored the association between sexual frequency and masturbation, evaluating the evidence for whether masturbation compensates for unavailable sex, complements (or augments) existing paired sexual activity, or bears little association with it. We found evidence supporting a compensatory relationship between masturbation and sexual frequency for men, and a complementary one among women, but each association was both modest and contingent on how content participants were with their self-reported frequency of sex...

INTRODUCTION: Spinal cord injury (SCI) is estimated to affect approximately 276,000 individuals in the United States. Since 2010, the mean age of individuals at the time of the SCI has been 42 years, with nearly 80% of cases involving men. This means that individuals with SCI generally are young men who typically place a great deal of importance on normal sexual and reproductive function. AIM: To assess the effect of sildenafil treatment on erectile function and the frequency of ejaculation in men with SCI...

PURPOSE: Considering the increased risk of HIV among alcohol users, we explored the role of individual alcohol expectancies in risk behaviors among youth in the Democratic Republic of the Congo. METHODS: We surveyed 1,396 adolescents (ages 15-19) and young adults (ages 20-24) on alcohol and sexual behaviors in May, 2010. We assessed expectancies of alcohol use (1) leading to sex or positive sexual experiences; (2) diminishing one's ability to resist unwanted sex; and (3) diminishing one's ability to use or negotiate use of condoms...

Homeless young adults ages 18-25 exhibit high rates of alcohol and other drug (AOD) use, and sexual risk behaviors such as unprotected sex. Yet few programs exist for this population that are both effective and can be easily incorporated into settings serving this population. This pilot cluster cross-over randomized controlled trial evaluates AWARE, a voluntary four session group-based motivational interviewing (MI) intervention to reduce AOD use and sexual risk behavior. We evaluated AWARE with 200 homeless young adults using drop-in center services in Los Angeles County (mean age=21...

The neuropeptides vasopressin (AVP) and oxytocin (OT) have been implicated in the regulation of numerous social behaviors in adult and juvenile animals. AVP and OT signaling predominantly occur within a circuit of interconnected brain regions known collectively as the "social behavior neural network" (SBNN). Importantly, AVP and OT signaling within the SBNN has been shown to differentially regulate diverse social behaviors, depending on the age and/or sex of the animal. We hypothesized that variation in the display of these behaviors is due in part to age and sex differences in AVP and OT synthesis within the SBNN...

Despite the sizable population of military-dependent youth (MDY) in the United States and the military stressors they experience (e.g., relocations, parental deployment), little is known about MDY's sexual behavior, especially about the perceived role that military stressors play in their sexual decisions, such as the decision to initiate sex. We conducted 25 semistructured, in-depth interviews with sexually experienced female MDY aged 15 to 19 years to (a) describe MDY's general perceptions of military life and (b) identify intrapersonal and interpersonal characteristics related to MDY's sexual initiation, including the perceived impact of military stressors...

BACKGROUND: Zambia experiences high unmet need for family planning and high rates of HIV, particularly among youth. While male condoms are widely available and 95% of adults have heard of them, self-reported use in the past 12 months is low among young adults (45%). This study describes factors associated with non-use of male condoms among urban young adults in Zambia. METHODS: A household cross-sectional survey in four urban districts was conducted from November 2015 to January 2016 among sexually active young adults ages 18-24 years...

INTRODUCTION: Surrounded by a variety of structures including the facial sinuses and the brain, the human orbit displays unique anatomical features. It is known that orbital volume correlates with age and sex. The aim of this study was to evaluate sexual dimorphism of orbital volume relative to the size of the skull, and to establish criteria for gender determination. METHODS: Orbital volume was measured from 3D models of the orbits. The volumes were expressed in relation to the centroid size of the skull, to ensure that any sexual dimorphism in orbital volume was not simply due to a difference in skull size...

Sex-specific differences in mitochondrial function and free radical homeostasis are reported in the context of aging but not well-established in pathogeneses occurring early in life. Here, we examine if sex disparity in mitochondria function, morphology, and redox status starts early and hence can be implicated in sexual dimorphism in cardiac as well as neurological disorders prevalent at young age. Although mitochondrial activity in the heart did not significantly vary between sexes, female brain exhibited enhanced respiration and higher reserve capacity...

OBJECTIVES: Nitrite inhalants (poppers) are commonly used recreational drugs among men who have sex with men (MSM) and were previously associated with elevated rates of high-risk sexual behavior, HIV and HHV-8 seroconversion, and transient immunosuppressive effects in experimental models. Whether long-term popper use is associated with cancer risk among MSM in the HAART era is unclear. DESIGN: Prospective cohort study of cancer risk in 3223 HIV-infected and -uninfected MSM in the Multicenter AIDS Cohort Study from 1996-2010...

BACKGROUND: The British Columbia Centre for Disease Control implemented a comprehensive Web-based testing service GetCheckedOnline (GCO) in September 2014 in Vancouver, Canada. GCO's objectives are to increase testing for sexually transmitted and blood-borne infections (STBBIs), reach high-prevalence populations facing testing barriers, and increase clinical STI service capacity. GCO was promoted through email invitations to provincial STI clinic clients, access codes to clients unable to access immediate clinic-based testing (deferred testers), and a campaign to gay, bisexual, and other men who have sex with men (MSM)...

BACKGROUND: Spirituality and religiosity may serve as both a resource and a barrier to HIV prevention with young black men who have sex with men (YBMSM). We examined indices of spirituality/religiosity as correlates of binge drinking, stimulant use, and recent HIV testing in a sample of YBMSM. METHODS: From 2011-2013, annual venue-based surveys of sexually active YBMSM ages 18-29 were conducted in Dallas and Houston, Texas. Binge drinking and stimulant use were assessed in the past two months...

OBJECTIVE: The human voice is sexually dimorphic in obvious ways, such as differences in fundamental frequency and gross laryngeal anatomy, but also in less apparent ways, such as in the prevalence and types of voice disorders and the manifestation of voice changes in advanced age. Differences between males and females are rarely explored, however, in mechanistic animal studies. The goal of this study was to explore sexual dimorphism in laryngeal function and structure in adult rats by examining ultrasonic vocalization acoustics and muscle fiber size and type in the thyroarytenoid muscle...

That many older individuals continue to engage in various forms of sexual expression well into later life is now well established in the literature. To date, however, only a small body of qualitative research has examined older men's experiences and understandings of sex in later life. Likewise, the ways in which older men's discussions on sex may be used as an avenue for "doing" masculinity remain underexplored. Older men are particularly interesting in this regard, as they inhabit an increasingly subordinated position in relation to hegemonic masculine ideals because of their age...
