Sexual violence history predicts changes in vaginal immune parameters during sexual arousal

Sexual Violence, Genital Cytokines, and Colposcopy Findings: A Cross-Sectional Study of Women Engaged in Sex Work in Mombasa, Kenya

BACKGROUND

Sexual violence (SV) increases human immunodeficiency virus (HIV) susceptibility in a sustained manner. This study evaluated genital cytokines and colposcopy findings in women reporting both recent and more remote SV.

METHODS

A cross-sectional study of HIV-1 negative Kenyan women who engage in sex work was performed. Cervicovaginal fluid was collected by menstrual cup and cytokines (IFNγ, TNFα, IL-1β, IL-6, IL-10, MIP-1α, MIP-1β, and CXCL10) measured using chemiluminescence. Cervical injury was assessed by colposcopy. Associations between recent (≤30 days prior), more remote (>30 days prior), and no (reference category) SV exposure and cytokine concentrations were evaluated using linear regression.

RESULTS

Among 282 participants, 25 (8.9%) reported recent SV and 123 (43.6%) reported more remote SV. Only two cytokines (IL-10 and CXCL10) were associated with the 3-category SV variable in bivariable modeling at the prespecified cutoff ( P < 0.2) and carried forward. In multivariable analyses, more remote SV (β = 0.72; 95% confidence interval [CI], 0.06-1.38; P = 0.03), but not recent SV (β = 0.20; 95% CI, -0.99 to 1.39; P = 0.74) was associated with cervicovaginal IL-10 compared with no SV. Recent (β = 0.36; 95% CI, -0.94 to 1.67; P = 0.58) and more remote (β = 0.51; 95% CI, -0.21 to 1.24; P = 0.16) SV were not associated with CXCL10 compared with no SV. Cervical epithelial friability (χ 2 = 1.3, P = 0.51), erythema (χ 2 = 2.9, P = 0.24), vascular disruption (χ 2 = 1.4; P = 0.50), epithelial disruption (χ 2 = 2.6, P = 0.27), or any colposcopy finding (χ 2 = 1.2, P = 0.54) were not associated with SV category by χ 2 test.

CONCLUSIONS

The mechanism linking SV to sustained increases in HIV susceptibility may not be related to persistent genital inflammation or injury.

Inflammation as a Potential Mechanism Contributing to Sexual Functioning Following Initiation of Gender-Affirming Hormone Therapy

Purpose of Review

Many transgender and gender non-conforming (TGNC) people seek gender-affirming hormone therapy (GAHT). While GAHT is generally safe and increases well-being, it is essential to accurately understand potential unintended effects and risk factors to better inform and manage treatment. This narrative review covers recent literature documenting changes in sexual function following the initiation of GAHT and explores inflammation as a potential mediator of these changes.

Recent Findings

Generally, the initiation of GAHT is correlated with increased sexual desire in transgender men and decreased sexual desire in transgender women, with time-limited effects that return to levels approaching baseline after about a year; there are also changes in inflammation markers that parallel this timeline. Findings on other aspects of sexual function (e.g., orgasm, pain, and sexual quality of life) are more limited. As there is evidence from cisgender populations that inflammation acts as a mechanism by which hormones influence sexual function, we propose applying this model to TGNC people taking GAHT.

Summary

Sexual function may change in TGNC patients receiving GAHT, and those changes may be influenced by inflammation. However, these changes often return to baseline as TGNC patients' bodies adjust to a new hormonal equilibrium.

Affective neuroscience: applications for sexual medicine research and clinical practice

INTRODUCTION

Affective neuroscience is the study of the brain substrates of emotional, embodied experiences. Affective neuroscience theory (ANT) is based on experimental evidence that all mammals are hardwired with 7 primary subcortical emotional operating systems, or "core emotions," that have overlapping but distinct circuits buried in the deep, ancient parts of the brain. Imbalances in the 7 core emotions can affect multiple aspects of the individual's psychosocial well-being (eg, depression, anxiety, substance abuse). Here, we propose that core emotions can also influence sexual function and, specifically, that imbalances in core emotions are the bridge connecting psychiatric symptoms (eg, anhedonia) to sexual dysfunction (eg, anorgasmia).

OBJECTIVES

In this targeted review and commentary, we outline potential connections between ANT and sexual medicine research and clinical practice. We summarize ANT by defining the 3-level BrainMind and core emotions; examining how they relate to personality, behavior, and mental health; and determining the implications for sexual health research and clinical practice.

METHODS

A targeted literature review was conducted. Case studies were adapted from client files and clinician interviews and then anonymized.

RESULTS

We propose a novel organizational schema for implementing affective balance therapies for sexual dysfunction, which integrate psychoeducational, somatic, and cognitive therapeutic approaches under the ANT framework. We provide 3 patient case studies (anorgasmia, hypersexuality, spinal cord injury) outlining the implementation of this approach and patient outcomes.

CONCLUSION

ANT has practical translational applications in sexual health research and clinical practice. By integrating our understanding of the role of core emotions in human sexuality, clinicians can better tailor treatments to address sexual dysfunction.

Prevalence and correlates of intimate partner sexual violence among pregnant women in Napak district, Northeastern Uganda

Intimate partner sexual violence (IPSV) during pregnancy is of key reproductive health concern as it is associated with various risks linked to severe intrapartum complications. This study assessed the prevalence and the correlates of intimate partner sexual violence among pregnant women in Napak district, Northeastern Uganda. This was an analytical cross-sectional study conducted among 284 pregnant women who were obtained by systematic sampling in Napak district between November and December 2020. A structured questionnaire was used to collect the data, and this was analyzed using STATA version 15. The correlates of IPSV were determined at a multivariable level using a Poisson regression model with robust variance at the individual, relationship, and societal levels of the socio-ecological model. The study enrolled 284 pregnant women of whom, 65.5% were aged between 18 and 28 years and 62.0% were not formally educated. Also, 56% of the pregnant women had experienced IPSV during their current pregnancies, the most prevalent form (35.6%) being unwanted sexual advances. Factors of women being in their third or subsequent pregnancies, primiparity, women who rated their communication with their partners as low, being in a relationship for less than five years, lower age of the spouse, and a lower level of education (primary) among women showed a statistical association with IPSV. This study reports a high prevalence of IPSV during pregnancy, and it was associated with individual, relationship, and societal factors. Based on this, concerted efforts through sensitization on the dangers of IPSV are required to avert the practice.
