BACKGROUND: Human papillomavirus (HPV) is one of the most common sexually transmitted infections worldwide. Recently a 9-valent HPV (9vHPV) prophylactic vaccine was licensed. Seroprevalence prior to vaccine dissemination is needed for monitoring vaccine effectiveness over time. Few studies have assessed the seroprevalence of 9vHPV types in men. OBJECTIVES: To investigate the seroprevalence of 9vHPV vaccine types and associated risk factors among men residing in Brazil, Mexico, and the United States...

Traits that facilitate competition for reproductive resources or that influence mate choice generally have a heightened sensitivity to stressors. They have evolved to signal resilience to infectious disease and nutritional and social stressors, and they are compromised by exposure to man-made toxins. Although these traits can differ from one species or sex to the next, an understanding of the dynamics of competition and choice can in theory be used to generate a priori predictions about sex-, age-, and trait-specific vulnerabilities for any sexually reproducing species...

BACKGROUND: Female sex workers (FSWs) in Bangladesh remain at elevated risk of sexually transmitted infections (STIs) although the human immunodeficiency virus (HIV) prevalence among them is low. Recent information on the burden and etiological diagnosis of STIs among them has been lacking. This study examines prevalence and risk behaviors of selected STIs among FSWs in Dhaka in 2014. METHODS: Between August and October 2014, a cross-sectional study was conducted among street-based and residence-based FSWs receiving HIV prevention services at 24 drop in centers in Dhaka...

BACKGROUND: Few prospective studies have assessed whether antiretroviral therapy (ART) use is associated with changes in sexual risk behavior of human immunodeficiency virus (HIV)-infected persons in known HIV-serodiscordant partnerships. METHODS: We conducted a longitudinal analysis of HIV-infected persons with known uninfected partners enrolled in the Partners Pre-Exposure Prophylaxis Study in Kenya and Uganda. Antiretroviral therapy use and self-reported sexual behavior were ascertained every 3 months...

Human papillomavirus (HPV) has been identified as the leading cause of cervical cancer. While HPV risk factors have been well studied, less is known about those with HPV and their perceptions about health ramifications. The purposes of this study were to examine unmarried college student women's (1) HPV diagnosis status and (2) perceived risk of getting cervical cancer in the next 5 years. Data were analyzed from 1106 unmarried, sexually active college women aged 18 to 26. Binary logistic regression compared HPV-related knowledge, vaccination-related perceptions, mandate support, healthcare utilization, sexual behaviors, and personal characteristics...

BACKGROUND: A variety of cutaneous human papillomaviruses (HPV) are detectable in genital epithelial lesions in men and non-melanoma skin cancer patients. It remains unclear whether these viruses are associated causally with skin lesions. To date, no study has prospectively examined the association between cutaneous HPV seropositivity and development of external genital lesions (EGLs) in men. OBJECTIVES: To examine the association between seropositivity to cutaneous HPV types and the risk of subsequent development of EGLs...

BACKGROUND: Sexually transmitted infections (STIs) are a major public health problem in developing countries. These diseases are associated with increased risk of transmission of human immunodeficiency virus as well as adverse outcomes on pregnancy and reproductive health. Sexual behavior and healthcare-seeking behavior are identified as the true risk factors of STIs. METHODS: Hospital-based cross-sectional study design was adopted. Eighty-five STI patients were studied regarding the inappropriate treatment-seeking behavior, the nature of the first point of contact with the health care, the appropriateness of treatment and the concerns of the patient regarding the services rendered by government health-care facilities...

Tramadol is a well-known and effective analgesic. Recently it was shown that tramadol is also effective in human premature ejaculation. The inhibitory effect of tramadol on the ejaculation latency is probably due to its mechanism of action as a μ-opioid receptor agonist and noradrenaline/serotonin (5-HT) reuptake inhibitor. In order to test this speculation, we tested several doses of tramadol in a rat model of male sexual behavior and investigated two types of drugs interfering with the μ-opioid and the 5-HT system...

Heidi Luft, Elaine Larson
Latina women in stable relationships have risks for human immunodeficiency virus and other sexually transmitted infections. Improving safe sexual communication (SSC) could enable women to accurately assess and mitigate their risk of infection within their relationship. Literature to identify psychosocial correlates that facilitate or inhibit SSC between Latina women and their partners has not yet been synthesized. The purpose of this study was to conduct an integrative review and synthesis of empirical and theoretical research that examines psychosocial correlates of SSC among adult Latina women from the United States, Latina America, and the Caribbean with stable male partners...

Human immunodeficiency virus (HIV) infection among men who have sex with men (MSM) has increased to a drastic proportion throughout India in the last couple of years due to a lack of productive identification and management framework. In apprehension of social disgrace these men attempt to live a normal hetero conjugal life and, in the process, act as a bridge in spreading the virus to their women partners. In this case report we have highlighted two cases which clearly distinguished the adequacy of HIV treatment among MSM when they are diagnosed during early or late phases of infection...

Oncogenic human papillomavirus (HPV) infection is a cause of many anogenital cancers in women and men; however, there is little research on HPV prevalence and risk factors that includes both women and men from the same population. A total of 4687 participants, including 2378 women and 2309 men aged 18-55 years old from the same community, were enrolled in the study in Liuzhou, China. Exfoliated cells were collected from the participants from different anatomic sites and were tested for 13 oncogenic and 3 non-oncogenic HPV types...

BACKGROUND: The human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) continue to be a major public health problem in Sub-Saharan Africa (SSA), particularly in Swaziland, which has the highest HIV prevalence in this region. A wide range of strategies and interventions have been used to promote behavior change, though almost all such interventions have involved mass media. Therefore, innovative behavior change strategies beyond mass media communication are urgently needed...

REVIEW
Marianne Brandon
INTRODUCTION: Few topics generate such controversy and emotional reactivity as the nature of human mating behavior. Unfortunately, and potentially to the detriment of good patient care, sexual medicine practitioners have largely avoided this matter. An understanding of the scientific literature can empower practitioners to more effectively confront the inevitable monogamy and nonmonogamy challenges present in research and clinical practice. AIM: To review and summarize relevant scientific literature as a context to evaluate the more common myths and misunderstanding relating to the practice of monogamy and nonmonogamy in humans...

Gert Holstege
INTRODUCTION: The brain has two goals: survival of the individual and survival of the species. It ensures that the body resides in safe circumstances and can obtain sufficient drink and food. It also has to produce and protect offspring. Its most important tool is its motor system, which consists of the voluntary and emotional motor systems. AIM: To explain how the brain uses its emotional motor system to control the pelvic organs. METHODS: Anatomic and physiologic data in cats and humans are used to find out how this motor system works and what parts of the brain and brainstem are involved...

REVIEW
Frida Printzlau, Jeanne Wolstencroft, David H Skuse
The X chromosome has played a critical role in the development of sexually selected characteristics for over 300 million years, and during that time it has accumulated a disproportionate number of genes concerned with mental functions. There are relatively specific effects of X-linked genes on social cognition, language, emotional regulation, visuospatial, and numerical skills. Many human X-linked genes outside the X-Y pairing pseudoautosomal regions escape X-inactivation. Dosage differences in the expression of such genes (which constitute at least 15% of the total) are likely to play an important role in male-female neural differentiation, and in cognitive deficits and behavioral characteristics, particularly in the realm of social communication, that are associated with sex chromosome aneuploidies...

Neonatal hypoxia-ischemia (HI) is an important cause of neurological deficits in humans, and the Levine-Rice model of experimental HI in the rat mimics the human brain lesion and the following sensory motor deficits and cognitive disabilities. With the growing evidence that sex influences all levels of brain functions, this Mini-Review highlights studies in which sex was a controlled variable and that provided evidence of sexual dimorphism in behavioral outcome, extension of brain damage, mechanisms of lesion, and treatment efficacy in the rat neonatal HI model...

Hormones orchestrate and coordinate human female sexual development, sexuality, and reproduction in relation to three types of phenotypic changes: life history transitions such as puberty and childbirth, responses to contextual factors such as caloric intake and stress, and cyclical patterns such as the ovulatory cycle. Here, we review the endocrinology underlying women's reproductive phenotypes, including sexual orientation and gender identity, mate preferences, competition for mates, sex drive, and maternal behavior...
