Receptive anal intercourse, multiple partners, condomless sex, sexually transmitted infections (STIs), and drug/alcohol addiction are familiar factors that correlate with increased human immunodeficiency virus (HIV) risk among men who have sex with men (MSM). To improve estimation to HIV acquisition, we created a composite score using questions from routine survey of 3588 MSM in Beijing, China. The HIV prevalence was 13.4%. A risk scoring tool using penalized maximum likelihood multivariable logistic regression modeling was developed, deploying backward step-down variable selection to obtain a reduced-form model...

This study investigated whether "bareback" (i.e., condomless) sexually explicit media (SEM) consumption is differentially associated with men who have sex with men's (MSM) concerns about, and willingness to have, condomless anal intercourse (CAI) versus anal intercourse with condoms. Participants were 659 Australian MSM who all reported their bareback SEM consumption and read a vignette in which they were propositioned for sex by a hypothetical male target. Participants were randomly assigned to one of four vignettes, in which the target exclusively preferred either CAI or anal intercourse with condoms, and either did or did not disclose that they took pre-exposure prophylaxis (PrEP)...

Somnophilia, the desire to have sex with an unconscious, sleeping, or comatose person who is unable to respond, is a sexual paraphilia that is seldom reported. The underlying desire is often overshadowed by the act of sexual violation and when using GHB or GBL to induce unconsciousness, as in the case presented here, the victim might not even be able to recall, for certain, that they have been sexually violated. A case study is offered of a somnophile who adulterated drinks to render young men unconscious, so he could rape them in that state, before progressing to administering drugs anally on the pretext of applying lubrication to the anus to facilitate sexual intercourse...

Dear Editor, Proper and consistent use of male condoms can be a highly effective method of preventing the transmission of sexually transmitted infections (STIs) and HIV (1), but this method relies on men's willingness and ability to use condoms. In the United States of America, about 20% overall and less than 50% of adults with multiple partners used a condom at last intercourse (2). In Serbia in 2013 (3), 50.0% of women and 62.5% of men aged 15-49 who had more than one partner in the past year used a condom during their last intercourse...

Despite the high HIV incidence and prevalence among black men who have sex with men (BMSM), little research has examined partner characteristics, partner seeking venue, sexual position, substance use, and sexual risk behavior at the sex event-level among BMSM. Using the baseline data from a multi-site study of 807 BMSM stratified by their HIV status, the goal of this study was to conduct a detailed event-level analysis of 1577 male anal sex events to assess the factors associated with condomless anal intercourse (CLAI) with a HIV-discordant or HIV status-unknown partner...

Practices related to resumption of coitus after childbirth remains poorly documented in Nigeria. This study examined factors associated with sexual intercourse, delivery-coitus interval, and contraceptive use among postpartum women attending a tertiary centre in Kano, northern Nigeria. A cross section of 317 women attending immunization, postnatal and family planning clinics within 12 months of childbirth was interviewed using a structured questionnaire. Vaginal intercourse was resumed by most women (n=212; 66...

HTLV-1 is transmitted primarily either through sexual intercourse or from mother to child. The mother/child pairs were classified as seroconcordant or serodiscordant. We analyzed mother to child transmission (MTCT) according to sociodemographic, clinical and epidemiological characteristics of the mother, child's gender and duration of breastfeeding. Between June 2006 and August 2016 we followed 192 mothers with HTLV-1 infection (mean age 41 years old), resulting in 499 exposed offspring, 288 (57.7%) of whom were tested for HTLV-1, making up the final sample for the study, along with their 134 respective mothers...

BACKGROUND: Morbidly obese patients are usually excluded from studies that compare Transvaginal Hybrid-NOTES Cholecystectomy (TVC) with traditional laparoscopic cholecystectomy. Therefore, these study results cannot necessarily be transferred to this group of patients. In this study, we have analyzed and compared the outcomes of the procedure with obese and non-obese patients. METHODS: Data from a prospectively maintained database were retrospectively analyzed. All the TVCs performed in our clinic since 2008 were divided into groups according to their body mass index (BMI)...

Background: Lymphogranuloma venereum (LGV) is a sexually transmitted infection (STI) caused by Chlamydia trachomatis genotypes L1 , L2 and L3 . This LGV is associated with significant morbidity and increased risk of HIV transmission. While fewer than two cases per year were reported in Quebec before 2005, LGV emerged in 2005-2006 with 69 cases, followed by a period of low incidence (2007-2012), and subsequent re-emergence since 2013. Objectives: To describe the incidence of LGV in Quebec and the characteristics of the affected population, including demographics and risk factors, clinical manifestations, laboratory tests, treatments and reinfection rates...

Men who have sex with men (MSM), who have heterogeneous HIV-acquisition risks are not specifically targeted in Kenyan pre-exposure prophylaxis (PrEP) guidelines. We used data from an open cohort, which followed 753 initially HIV-negative MSM participants for more than 1378.5 person-years, to develop an empiric risk score for targeting PrEP delivery. Independent predictors of incident HIV-1 infection in this cohort were an age of 18-24 years, having only male sex partners, having receptive anal intercourse, having any unprotected sex, and having group sex...

INTRODUCTION: Peyronie's disease (PD) affects up to 9% of the male population. PD causes scarring of the tunica albuginea of the penis which leads to penile deformity making sexual intercourse difficult or impossible. PD also causes significant psychological, emotional and relationship difficulties for both patient and partner. Up until the licencing of Collagenase clostridium histolyticum (CCH) (Xiapex®, Xiaflex®), surgical correction of the penile deformity was the mainstay of treatment...

REVIEW
Lucia Regina Cangussu da Silva
Sexual transmission of Zika virus (ZIKV) is a matter of great concern. Infectious viral particles can be shed in semen for as long as six months after infection and can be transferred to male and female sexual partners during unprotected sexual intercourse. The virus can be found inside spermatozoa and could be directly transferred to the oocyte during fertilization. Sexual transmission of ZIKV can contribute to the rise in number of infected individuals in endemic areas as well as in countries where the mosquito vector does not thrive...
