The timing of transitions to sexual activity, marriage and childbearing in sub-Saharan Africa is undergoing profound changes. This study investigates the determinants of adolescent transitions in South Nyanza, a socioeconomically deprived setting in Kenya where adolescent reproductive health is a particular concern. The analysis is based on Cox regression of timing of first sexual intercourse, first marriage and first pregnancy, using data from a survey of 1247 females aged 12-19 years. The results show that higher household socioeconomic status and educational attainment are associated with delayed onset of all three transition events. Furthermore, mother's higher educational attainment is protective for initiation of sexual intercourse while rural residence is protective for pregnancy experience. Other protective factors include communication with parents or with fellow girlfriends. However, discussing sexual matters with boyfriends, high internal locus of control, and gender bias are associated with early onset of the three transition events.

Importance: Sexual dysfunction is a common adverse effect of prostate cancer treatment, and current management strategies do not adequately address physical and psychological causes. Exercise is a potential therapy in the management of sexual dysfunction.
Objective: To investigate the effects of supervised, clinic-based, resistance and aerobic exercise with and without a brief psychosexual education and self-management intervention (PESM) on sexual function in men with prostate cancer compared with usual care.

Synergistic interactions between substance use and violence (SAVA syndemic) are strongly associated with heightened risk for HIV acquisition in the African American population. While couple-based interventions have shown efficacy among at-risk and HIV-positive serodiscordant couples, no interventions have specifically targeted SAVA syndemic risk reduction for HIV-negative, high-risk, heterosexual African American couples in the United States. This pilot study tested the feasibility, safety, and preliminary effects of an integrated sexual risk reduction intervention for African American couples.

In forensic science, detecting transfers of physical and biological material is critical for establishing evidence of criminal involvement. Unique bacterial signatures from the reproductive system transfer during unprotected penetrative intercourse offer a novel tool for criminal investigation. Here, we demonstrate this transfer using full-length 16S rRNA gene sequencing and discuss the impact of barrier contraceptives.
