There is a notable gap between heterosexual men and women in frequency of orgasm during sex. Little is known, however, about sexual orientation differences in orgasm frequency. We examined how over 30 different traits or behaviors were associated with frequency of orgasm when sexually intimate during the past month. We analyzed a large US sample of adults (N = 52,588) who identified as heterosexual men (n = 26,032), gay men (n = 452), bisexual men (n = 550), lesbian women (n = 340), bisexual women (n = 1112), and heterosexual women (n = 24,102)...

Breeding groups of Japanese medaka (Oryzias latipes) were exposed to atrazine at measured concentrations of 0.6, 5.5, and 53 µg/L for 35 d. Evaluated endpoints included survival, fecundity, fertility, growth (weight and length), behavior, secondary sex characteristics (anal fin papillae), gonad histopathology, and hepatic vitellogenin. No statistically significant effects of atrazine exposure on survival and growth of medaka were noted during the test, and mean survival was ≥97.5% in all treatment groups on Day 35...

Young men who have sex with men (MSM) of color are at increased risk for HIV infection. Mpowerment (MP) is an intervention designed to reduce risky sexual behavior and increase HIV testing among young MSM ages 18-29. From 2009 to 2012, three community-based organizations with support from the U.S. Centers for Disease Control and Prevention evaluated MP among N = 298 participants. Following a repeated measures design, data from 3- and 6-month follow-ups were compared to baseline. HIV testing and self-efficacy for safer sex increased at both follow-up time points; self-acceptance as an MSM was higher at follow-up 2...

Numerous partner and relationship characteristics are associated with sexual risk behavior among young men who have sex with men (YMSM), including being in a serious relationship and having older partners. However, most research in this area is limited by its reliance on variable-centered approaches. Using multilevel latent class analysis, this study identified subgroups of sexual partner types with a particular emphasis on examining whether partner type moderated the association between drug use and condomless anal sex (CAS)...

BACKGROUND: In 2013, guidelines were released for reducing the risk of viral bloodborne pathogen transmission through organ transplantation. Eleven criteria were described that result in a donor being designated at increased infectious risk. Human immunodeficiency virus (HIV) and hepatitis C virus (HCV) transmission risk from an increased-risk donor (IRD), despite negative nucleic acid testing (NAT), likely varies based on behavior type and timing. METHODS: We developed a Monte Carlo risk model to quantify probability of HIV among IRDs...

BACKGROUND: The incidence of penile cancer in Indian men is high. Little is known about genital human papillomavirus (HPV) infection in Indian HIV-seropositive men who have sex with men (MSM), a population that may be at particularly high risk for genital HPV infection and, potentially, penile cancer. In this study, we assessed the prevalence and risk factors for genital HPV infection in this population. DESIGN AND METHODS: Three hundred HIV-seropositive MSM were recruited from 2 clinical sites in India...

In the absence of an effective vaccine, strategies to prevent HIV transmission are urgently needed. Condomless receptive anal intercourse represents a major route of transmission, and efforts are being made to develop strategies in which potent anti-HIV drugs are formulated for topical application to the rectum prior to sex. 5P12-RANTES is a promising candidate for such a purpose. It is an analogue of the human chemokine RANTES/CCL5, which potently blocks CCR5, the principal coreceptor used by HIV to enter and infect target cells...

Intimate partner violence (IPV) rates are disproportionately high among sexual minority populations, with increasing evident that gay men experience IPV at the same rates as heterosexual women. This study examines the relationship between self-reported condomless anal intercourse (CAI) and IPV among a sample of 750 gay and bisexual men. Participants answered questions regarding recent receipt and perpetration of IPV using the IPV-GBM Scale (Cronbach Alpha 0.90). Of the sample, 46.1% reported recent receipt of any type of IPV and 33...

OBJECTIVE: Using a generational approach, this study analyses how unprotected anal intercourse has evolved since 1991 in France across different generations of men who have sex with men (MSM) whose sexual lives began at different periods in the history of the HIV epidemic. DESIGN: Data were collected from 18-59 year-old respondents to the French Gay Press surveys Enquêtes Presse Gay, conducted repeatedly between 1991 and 2011 (N = 32,196) using self-administered questionnaires distributed in gay magazines and over the internet...

Community-wide awareness that antiretroviral therapies (ART) provides protection against HIV has the potential to increase perceived safety and thereby increase condomless anal sex among men who have sex with men (MSM). Furthermore, reductions in condom use can increase exposure to sexually transmitted infections, which in turn can reduce the protective effects of ART on HIV transmission. The current study extends previous community-based behavioral surveillance research on beliefs regarding use of ART for HIV prevention and sexual practices among MSM...

Increased viral load during early HIV infection (EHI) disproportionately contributes to HIV transmission among gay men. We examined changes in sexual behavior that may pose a risk of HIV transmission (condomless anal sex (AS) with a serodiscordant or unknown status partner, CAS-SDU) in a cohort of 25 gay men newly diagnosed during EHI who provided information on 241 sexual partners at six time points following diagnosis. Twenty-two (88%) participants reported ≥1 AS partner (median time to first AS 80 days) and 12 (55%) reported ≥1 partnership involving CAS-SDU (median 116 days)...

BACKGROUND: Men who have sex with men (MSM) are a high-risk group for sexually transmitted diseases (STDs) and human immunodeficiency virus (HIV) infection. In China, the vast majority of MSM feel forced to marry or plan to marry women, according to traditional Chinese culture. Women who have regular sexual relations with MSM, called tongqi in mainland China, live with a high risk of STDs or HIV infection, but these risks are often ignored. Our investigation of this group of the women is a preliminary study that aims to understand the sexual health problems of tongqi and related factors...

We describe changes in sexual behaviors among men who have sex with men (MSM) following initiation of pre-exposure prophylaxis (PrEP) in a clinic-based sample of MSM initiating PrEP in Providence, Rhode Island. Data were collected at baseline, 3, and 6 months following PrEP initiation including total number of anal sex partners and condom use. A longitudinal mixed effects model assessed changes in number of partners and condom use over time, adjusting for age, race, and education. There was no statistically significant difference in total number of partners over time...

Sexual dimorphism is the most conspicuous difference between the sexes. This study examines possible sexual dimorphism and the relative growth patterns of morphometric characteristics in the marine medaka, Oryzias dancena for their potential to help differentiate between males and females of this species. The von Bertalanffy growth parameters estimated by a non-linear regression method were L∞=30.2 mm, K=3.22/year, and τ0=-0.05. All 18 characteristics measured showed a difference between males and females from 70 days after hatching...

In 2016, gay, bisexual, and other men who have sex with men (MSM) comprise more than half of all new HIV diagnoses in the United States, with the primary mode of infection being condomless anal sex (CAS). While studies report an association between use of Internet-based social networking sites and increased CAS, the research on the relationship between cell phone mobile applications (e.g., Grindr, Scruff, Jack'd) and CAS is much less developed. The present study examines whether the manner in which gay, bisexual, and other MSM find sexual partners predicts an increase in likelihood of engaging in CAS in an urban, noncoastal U...
