The present experiment examined the effects of a single neonatal injection of 1 mg or 100 micrograms of testosterone propionate (TP) on the sexual behavior and morphology of the female Mongolian gerbil. Four groups were created: vehicle-treated males (VM), 1-mg TP-treated females (HTP), 100-micrograms TP-treated females (LTP), and vehicle-treated females (VF). In adulthood, tests of sexual behavior were carried out after gonadectomy and appropriate hormone replacement therapy. Results indicated that LTP, HTP, and VM animals were significantly less receptive than VF animals. In addition, VM animals displayed significantly more male sexual activity than HTP, LTP, or VF animals. Immediately after the final test for male sexual behavior, subjects were weighed, anogenital distances recorded, and scent glands measured (length and width). Results indicated that a significant degree of morphological masculinization had occurred in HTP subjects for all measures and for LTP subjects for scent gland width and anogenital distance. These findings suggest that in the gerbil, significant morphological masculinization and behavioral defeminization can both occur in teh absence of significant behavioral masculinization.

Gender disparities in attitudes, norms, and perceived control related to intentional condomless sexual intercourse: A psychosocial theory-driven comparison among cisgender heterosexual male and female college varsity athletes in Taiwan.
Int J Clin Health Psychol
October 2024
Institute of Health Behaviors and Community Sciences, College of Public Health, National Taiwan University, Taipei, Taiwan.
Background: While condom use has been extensively studied as a protective behavior, research directly focusing on condomless sexual intercourse (CSI) as a distinct and intentional risk behavior, particularly regarding gender differences, remains scarce.
Methods: Building upon the Theory of Planned Behavior (TPB), this study addresses this gap by comparing TPB factors and individual TPB items regarding intentional CSI among cisgender heterosexual college varsity athletes in Taiwan ( = 1348).
Results: High CSI intention was more prevalent among men (53.
The Problem: People use social media platforms to chat, search, and share information, express their opinions, and connect with others. But these platforms also facilitate the posting of divisive, harmful, and hateful messages, targeting groups and individuals, based on their race, religion, gender, sexual orientation, or political views. Hate content is not only a problem on the Internet, but also on traditional media, especially in places where the Internet is not widely available or in rural areas.

PLoS One

Agència de Salut Pública de Barcelona (ASPB), Barcelona, Spain.
Background: In May 2022, after the suspension of the mobility restrictions due to the COVID-19 pandemic, the first outbreak of MPOX virus, transmitted from human to human, was detected outside of Africa, affecting mostly sexually active men who have sex with men. Our aim is to report the first outbreak of MPOX in Barcelona city in the period from 5/2022 to 5/2023 and the subsequent surge of cases in 8/2023.
Methods: We performed a descriptive study of all notified cases in city residents, obtained through epidemiological surveys.
Racism, homophobia, and the sexual health of young Black men who have sex with men in the United States: A systematic review.
PLoS One
January 2025
School of Nursing, Duke University, Durham, NC, United States of America.
Black gay, bisexual, and other men who have sex with men (BMSM) experience the highest rates of HIV acquisition annually out of any population in the United States, and young BMSM (YBMSM) are heavily impacted by this inequity as they enter adulthood. Despite a high annual HIV incidence, extant literature has found BMSM to engage in fewer sexual risk behaviors than White and Hispanic/Latino men who have sex with men, resulting in a gap between risk behaviors and the inequity of HIV infection. Structural factors, such as racism and homophobia, are thus being examined in order to understand this disconnect between behavior and HIV incidence.
