Purpose: To characterize the differences and similarities among college freshmen, sophomores, juniors, and seniors regarding their sexual behavior including contraception choices and human immunodeficiency virus (HIV) risk.
Methods: A 41-item sexual behavior questionnaire designed for this study was administered to a convenience sample (N = 797) of a college population.
Results: Levels of sexual activity were found to be comparable to other college-based surveys. Notable trends included an increased level of oral contraceptive use among partners reported by seniors, as compared to freshmen, without a corresponding increase in condom use; an increased reliance among seniors, as compared to freshmen, on women to provide contraception; and a low level of self or partner HIV testing either before or after initiating sexual intercourse. Gender differences also revealed greater partner relationship duration, intensity, and communication prior to initiating sexual intercourse among women versus men (p < or = .001).
Conclusions: Sexual behavior among college students differs across the 4 years with regard to rates of intercourse, contraception choice, and responsibility, as well as HIV testing and partner trust. University- and college-based health care programs should address sexual behavior with an awareness of the differences that exist in the four cohorts of students.

Prophylaxis based on antiretrovirals, such as pre-exposure prophylaxis to HIV (PrEP), has the potential to protect the populations most vulnerable to infection, which renews optimism for controlling the HIV epidemic. Against this backdrop, the aim of this article is to analyze the perceptions, negotiations and tensions surrounding the use of PrEP by men who have sex with men (MSM). This is a qualitative cross-section of a multicenter study, analyzing semi-structured interviews with 18 users of specialized HIV/AIDS healthcare facilities in the city of São Paulo/SP.

The implementation of the Transsexualizing Process (TP) / Gender-affirming Surgeries (GAS) in the Unified Health System (SUS) was the result of social struggles by the LGBT community for sexual rights, the construction of gender identity, and bodily autonomy. The scope of this article is to analyze the advances and challenges of TP/GAS in the SUS, through a qualitative narrative literature review. In June 2022, searches were conducted in the Google Scholar, SciELO, and VHL databases to select scientific articles in Portuguese published in the last 10 years, excluding articles in foreign languages and other types of academic work such as reviews, undergraduate theses, dissertations, and/or graduate theses.

Purpose: Adolescent girls are at high risk for depression and human immunodeficiency virus (HIV) acquisition. Poor mental health can increase vulnerability to risky sexual behaviours. Therefore, this study aims to determine the prevalence of depressive symptomology and explore the convergence of HIV risk factors with depressive symptoms amongst cis-gender adolescent girls and young women (AGYW) in rural KwaZulu-Natal (KZN) and peri-urban Western Cape (WC) communities in South Africa.

Transgender (TG) people are individuals whose gender identity and sex assigned at birth do not match. They often undergo gender-affirming hormone therapy (GAHT), a medical intervention that allows the acquisition of secondary sex characteristics more aligned with their individual gender identity, providing consistent results in the improvement of numerous socio-psychological variables. However, GAHT targets different body systems, and some side effects are recorded, although not yet fully identified and characterized.
