Childhood Trauma, Gender, and Sexual Health: Why Do Sexual Consequences Differ Between Men and Women?

1. Introduction

Childhood trauma is a public health problem of exceptional scale: an estimated 3.4 million children in the United States were reported as abused or neglected in 2012, one in four children experiences some form of maltreatment, and the estimated lifetime economic cost of childhood maltreatment reaches $124 billion per year (Campbell et al., 2016). The Adverse Childhood Experiences framework established that childhood abuse, neglect, and household dysfunction show strong, graded relationships with the leading causes of adult morbidity and mortality (Campbell et al., 2016; Dube et al., 2003). Crucially for this review, the ACE literature connects childhood adversity directly to sexual health endpoints — smoking, substance use, sexually transmitted infections, unintended pregnancy, and male involvement in teen pregnancy all rise in a dose–response fashion with ACE count (Dube et al., 2003), and individuals with four or more ACEs are significantly more likely to engage in risky sexual behavior (Font & Maguire-Jack, 2016; Garrido et al., 2018).

Within this broad landscape, one question has proven persistently difficult: why do the sexual consequences of childhood trauma differ between men and women? Part of the difficulty is evidentiary. Meta-analytic work confirms that CSA is a significant risk factor for adult sexual dysfunction (pooled OR = 1.68, 95% CI [1.49, 1.87]) (Wang et al., 2022), but the same analysis reveals gendered contours: the association is somewhat stronger in women (OR = 1.62, 95% CI [1.42, 1.83]) than in men (OR = 1.45, 95% CI [1.05, 1.84]) (Wang et al., 2022). Meanwhile, systematic reviews of male survivors find both confirmation of dysfunction (low drive, arousal problems, orgasmic difficulties, pain) and studies that fail to find any association — a heterogeneity attributed to variable definitions, methodology, and the profound underrepresentation of men in this literature (Bigras et al., 2020; Gewirtz-Meydan & Opuda, 2022).

This review addresses three questions: What are the gendered patterns of sexual consequences following childhood trauma? What mechanisms plausibly generate these differences? What are the clinical implications of a more gender-differentiated understanding? Given the weight of the evidence, we draw predominantly on foundational, highly cited studies — prospective birth cohorts, landmark meta-analyses, and longitudinal investigations of abuse sequelae.

2. Review Methodology

This narrative review was conducted to synthesize peer-reviewed evidence on gendered patterns and mechanisms in the sexual-health consequences of childhood trauma. A structured, though non-systematic, literature search was undertaken across PubMed/MEDLINE, PsycINFO, and Web of Science, supplemented by Google Scholar and by hand-searching the reference lists of retrieved meta-analyses, systematic reviews, and foundational prospective studies to identify additional primary and mechanistic sources not captured by the initial search terms. Search terms combined variants of "childhood sexual abuse," "childhood trauma," "child maltreatment," and "adverse childhood experiences" with outcome terms including "sexual dysfunction," "sexual risk behavior," "revictimization," "teen pregnancy," "sexual self-schema," and process terms including "gender differences," "sex differences," "emotion regulation," "dissociation," "attachment," and "HPA axis," combined using Boolean operators. The search was restricted to English-language, peer-reviewed publications and foundational scholarly books, with no fixed lower date bound given the review's reliance on landmark prospective cohort and epidemiological studies established over several decades, and an upper bound of June 2026.

Studies were eligible for inclusion if they reported a quantitative association, or a theoretically grounded mechanistic account, linking childhood sexual, physical, or emotional trauma to an adult or adolescent sexual-health outcome (sexual dysfunction, sexual risk behavior, revictimization, pregnancy involvement, or sexual self-concept), or if they established population-level baseline rates of sexual dysfunction necessary for interpreting trauma-exposed samples in context. Meta-analyses and systematic reviews meeting these criteria were prioritized as primary evidentiary anchors, supplemented by prospective cohort, epidemiological, and mechanistic (neurobiological or psychophysiological) studies, and by foundational theoretical works on attachment and sexuality where they informed the review's mechanistic argument. Studies were excluded if they addressed only pediatric outcomes without adult or adolescent sexual-health relevance, were case reports, were not published in English, or did not report an extractable association or theoretical mechanism germane to the review's central question of why sexual consequences of childhood trauma diverge by gender. Titles and abstracts identified through the search strategy were screened for relevance, full texts of potentially eligible studies were reviewed, and reference lists of included studies were examined for additional eligible sources (snowball/hand-search identification). This process yielded 65 sources meeting inclusion criteria, comprising 11 meta-analyses or systematic reviews, 5 prospective cohort or longitudinal studies, 5 mechanistic or neurobiological studies, and 44 additional epidemiological, cross-sectional, or theoretical sources (including two foundational scholarly books on attachment), synthesized narratively to integrate heterogeneous designs and outcome domains rather than through formal meta-analytic pooling. This review followed the Scale for the Assessment of Narrative Review Articles (SANRA) reporting guideline; the completed SANRA checklist accompanies this submission as a supplementary file.

3. Childhood Trauma and Adult Sexual Health: The Epidemiological Landscape

3.1. The Burden of Childhood Adversity

The ACE study, conducted among adult members of the Kaiser Health Plan, demonstrated strong graded relationships between cumulative childhood adversity and priority health and social problems including smoking, unintended pregnancies, sexually transmitted diseases, male involvement in teen pregnancy, alcohol problems, and attempted suicide (Dube et al., 2003). A national household survey in England replicated these patterns, showing that ACE count predicts health-harming behaviors across the life course and, critically, that childhood adversity is associated with subsequent unintended pregnancies and with being both a victim and perpetrator of violence, including intimate partner violence — a mechanism for the intergenerational passage of ACEs and their health consequences (Bellis et al., 2014). The pathways from abuse to adult health risk run partly through adult socioeconomic conditions (Font & Maguire-Jack, 2016), but a substantial direct pathway through behavior, including sexual behavior, remains.

3.2. Baseline Gender Differences in Sexual Health

Interpreting trauma effects requires knowing the baseline epidemiology of sexual dysfunction, which is itself strongly gendered. Epidemiological synthesis indicates that approximately 40–45% of adult women and 20–30% of adult men have at least one manifest sexual dysfunction (Lewis et al., 2010). The landmark U.S. National Health and Social Life Survey data, as reported in later syntheses, estimated that 43% of women and 31% of men experienced sexual dysfunction, with low sexual desire (22%), arousal difficulty (14%), and sexual pain (7%) the leading problems in women (Atif et al., 2016; McCool-Myers et al., 2016). In the 29-country Global Study of Sexual Attitudes and Behaviors (27,500 adults aged 40–80), 28% of men and 39% of women reported at least one sexual dysfunction, with early ejaculation (14%) and erectile difficulties (10%) most common in men, and lack of sexual interest (21%), inability to reach orgasm (16%), and lubrication difficulties (16%) most common in women (Nicolosi et al., 2004). These problems persist and increase into older age; in one national sample of adults aged 57–85, sexual problems were highly prevalent in both sexes, and 34.8% of men aged 40–70 in the Massachusetts Male Aging Study reported some degree of erectile difficulty (Laumann & Waite, 2008). This baseline asymmetry — women reporting roughly double the dysfunction burden of men — sets the stage for interpreting trauma-related differences.

3.3. Trauma Exposure and Sexual Outcomes: Meta-Analytic Evidence

Across the broader category of childhood maltreatment, a meta-analysis of studies up to April 2019 found that childhood maltreatment was significantly associated with early sexual debut (OR = 2.22, 95% CI [1.64, 3.00]), multiple sexual partners (OR = 2.22, 95% CI [1.78, 2.76]), transactional sex (OR = 3.05, 95% CI [1.92, 4.86]), and unprotected sex (OR = 1.59, 95% CI [1.22, 2.09]) (Wang et al., 2019). The effect sizes are thus substantial and consistent across subtypes of maltreatment. CSA specifically confers a distinctive burden: reviews conclude that because CSA occurs in close relationships and involves sexual acts and betrayal, it affects sexual well-being in adulthood more than other forms of childhood trauma, although associations are not unanimous across all domains of sexual well-being and are moderated by comorbidity and sample characteristics (Bigras et al., 2020).

4. Gendered Patterns of Sexual Consequences

4.1. Sexual Dysfunction

The strongest meta-analytic evidence for gender differences comes from the CSA–sexual dysfunction meta-analysis reported above: both sexes show elevated dysfunction, but the odds ratio is larger for women (1.62 vs. 1.45), and — tellingly — currently known interventions for post-CSA sexual dysfunction have only been evaluated in women (Wang et al., 2022). Among women, CSA survivors report more sexual dysfunction and less sexual satisfaction than non-abused controls (Rellini & Meston, 2007), with pervasive sexual difficulties documented across adolescence and adulthood (DiLillo, 2001). Notably, CSA status moderates the association between sexual functioning and sexual distress: women with CSA histories show higher distress even in the context of good sexual functioning, and this disconnect is most pronounced when the abuse was perpetrated by a family member (Stephenson et al., 2012).

For men, the picture is more fragmented. A systematic review of male survivors identified evidence for low sexual drive, problems with arousal, difficulties with orgasm, and pain, yet other studies failed to find correlations between CSA and sexual function in men, with the wide range in quality, methodology, and definitions presenting serious challenges to consistent analysis (Gewirtz-Meydan & Opuda, 2022). Community-based evidence suggests that both women and men who experienced sexual abuse report more symptoms of sexual dysfunction — including pain during intercourse, difficulty achieving and maintaining arousal, premature or delayed orgasm, and anxiety about sexual performance — while women with histories of sexual or physical abuse also report less frequent sexual activity (DiLillo et al., 2009). Taken together, the evidence supports a pattern in which women's trauma-related sexual dysfunction is robust and consistent across studies, whereas men's is real but inconsistently detected — a difference driven in part by measurement and sample issues rather than absence of effect (Bigras et al., 2020; Gewirtz-Meydan & Opuda, 2022).

4.2. Sexual Risk Behavior and HIV Vulnerability

Sexual risk behavior following childhood trauma is a well-established pathway in women. In a landmark review of controlled studies, CSA was consistently associated with sexual risk behavior among at-risk adult women — those with HIV, drug use, mental illness, incarceration, or homelessness — including having a partner at risk for HIV, more than 10 lifetime partners, sex trading, unprotected intercourse, and alcohol- or drug-involved sex (Senn et al., 2008). Among HIV-infected women, CSA rates are estimated at 32–59% (Mosack et al., 2010), and a continuum-of-risk hypothesis links early childhood abuse to later domestic violence and subsequent HIV-risk behavior (Cohen et al., 2000). The syndemic framework adds that substance abuse, violence, and HIV interact, with abuse increasing HIV risk through sexual risk patterns, forced sex, decreased condom negotiation, sex exchange, and psychological mediators such as depression, PTSD, and substance use (Malow et al., 2006; Meyer et al., 2011).

Comparable risk behavior is documented in maltreated men — the meta-analytic associations with early debut, partner number, transactional sex, and unprotected sex apply across sexes (Wang et al., 2019) — but the framing differs. Where women's risk is typically analyzed in terms of vulnerability to infection and victimization, men's risk appears in relation to perpetration, early fatherhood, and multiple partnerships; ACE studies specifically flag male involvement in teen pregnancy as an ACE-linked outcome (Dube et al., 2003). Prospective data from maltreated samples show that sexual and physical abuse remain significant predictors of risky sexual behaviors in adolescence even when alternative explanatory variables are controlled (Noll et al., 2019).

4.3. Pregnancy and Parenthood

Perhaps the most striking gender-specific finding concerns teen pregnancy. In the multigenerational longitudinal study of abused females, sexually abused girls reported significantly higher rates of teen pregnancy (39% vs. 15%) and teen motherhood (23.8% vs. 8%) than matched comparisons (Trickett et al., 2011). Sexual abuse remained a unique predictor of adolescent motherhood after controlling for other maltreatment types and contextual risk factors (Noll et al., 2019). Population-based survey data from Minnesota (29,187 and 25,002 students) show that while sexual abuse was reported by 6% of males and 27% of females in 1992 (9% and 22% in 1998), pregnancy involvement was significantly more common among abused adolescents of both sexes — 13–26% of females and 22–61% of males depending on abuse type, versus 8–10% among non-abused adolescents — and the differential in odds of pregnancy involvement between abused and non-abused was larger for males than females (Saewyc et al., 2004). This counterintuitive finding — that abused boys show a proportionally greater elevation in pregnancy involvement than abused girls — illustrates how the same underlying exposure can produce sex-specific behavioral expressions, with risk taking in boys and earlier, more frequent pregnancy in both sexes (Saewyc et al., 2004; Trickett et al., 2011).

4.4. Revictimization

Revictimization is the most consistently documented sexual consequence of CSA, and here the literature is dominated by female samples. Approximately one-third of CSA victims report repeated victimization, with a two- to three-fold greater risk of adult sexual revictimization than women without abuse histories (Arata, 2002; Widom et al., 2008). In a 15-year prospective study, abused females were almost twice as likely to experience sexual revictimization (odds = 1.99) and physical revictimization (odds = 1.96) than comparison females, with revictimizations more likely perpetrated by older, non-peer offenders and characterized by physical injury (Barnes et al., 2009). Roughly half of CSA victims report sexual revictimization later in life, and in a large prospective Australian sample the CSA–physical assault relationship was moderated by sex, with a stronger association for female victims (Papalia et al., 2021).

The mechanisms of revictimization are instructive for gender theory: PTSD symptoms mediated the relationship between CSA and subsequent revictimization in prospective work (Ullman et al., 2009), and a systematic review of 25 studies identified co-occurring maltreatment, risky sexual behavior (particularly in adolescence), PTSD, emotion dysregulation, and maladaptive coping as risk factors — with perceived parental care as the sole protective factor (Scoglio et al., 2021). Abuse severity predicts revictimization through coping and trauma symptoms (Fortier et al., 2009), and multi-risk models show CSA increases risk of adult sexual assault beyond peer sexual abuse (Maker et al., 2001). Notably, most revictimization research — like most CSA research generally — samples women, leaving male revictimization, particularly outside institutional settings, substantially uncharacterized (Arata, 2002; Scoglio et al., 2021).

4.5. Sexual Distortion: Compulsivity and Avoidance

Prospective data reveal that CSA affects not just the frequency but the meaning of sexuality. In the landmark prospective study by Noll and colleagues, sexually abused participants evidenced heightened sexual preoccupation, while those abused by a biological father scored higher on sexual aversion and sexual ambivalence — a pattern the authors term "sexual distortion" (Noll et al., 2003). The same study hypothesized that CSA would be associated with early voluntary coital initiation, more sexual partners, higher STD and HIV-risk behavior, ineffective birth control, higher pregnancy rates, and lower age at first birth — outcomes subsequently confirmed in this cohort (Noll et al., 2003). Reviews corroborate that CSA may relate to sexual compulsivity as well as dysfunction and low satisfaction (Bigras et al., 2020), and men with histories of military sexual trauma show elevated sexual compulsivity and erectile dysfunction (Blais et al., 2022). The coexistence of approach and avoidance — hypersexuality in some domains and aversion in others — complicates simple gender narratives: both sexes can exhibit either pole, but the distribution appears skewed, with sexual aversion and ambivalence more thoroughly documented in women (Noll et al., 2003; Stephenson et al., 2012).

5. Why Do Consequences Differ? Mechanistic Accounts

5.1. Neurobiological Embedding

Childhood trauma becomes biologically embedded through the stress response system. Chronic fear and threat exposure lead to repeated activation of the hypothalamic-pituitary-adrenal axis, altering glucocorticoid regulation; childhood trauma is associated with HPA upregulation — elevated baseline cortisol, greater increases and slower declines of cortisol following stress — alongside effects on the hippocampus, prefrontal cortex, and amygdala (Cross et al., 2017). Early adversity produces both exaggerated and attenuated cortisol and ACTH patterns, with a proposed trajectory from initial hyperactivation under excessive stress to chronic adrenal hyporeactivity (Tyrka et al., 2013). These effects are developmentally sensitive: early-life stress during the first two years may yield HPA hyperactivity and higher depression risk, whereas stress during the hyperactive phase of adolescence may yield a hypoactive, hyporesponsive HPA axis and higher PTSD risk (Agorastos et al., 2019). Early stressors also alter noradrenergic systems, with the hippocampus centrally implicated (Bremner & Vermetten, 2001), and sustained sympathetic hyperarousal with allostatic load along HPA connections has been theorized as the basis of adult psychopathology following early trauma (Murphy et al., 2022).

How does this produce sexual differences? Stress-system dysregulation intersects with the neuroendocrine substrates of sexual response — arousal, desire, and genital responding depend on integrated limbic-hypothalamic circuitry that trauma remodels (Bremner & Vermetten, 2001; Cross et al., 2017). Because the developmental timing, prevalence, and phenomenology of abuse differ by gender, and because sex steroids modulate both stress responsivity and sexual function, the same trauma can plausibly be channeled into different sexual phenotypes — hyperarousal-linked avoidance in one sex, numbing-linked risk behavior in another. Direct tests of these sex-specific neuroendocrine pathways in sexual outcomes remain a major gap (Agorastos et al., 2019).

5.2. Emotion Regulation, Dissociation, and PTSD

Psychological mechanisms are better established. Cumulative childhood trauma predicts affect dysregulation, and affect dysregulation predicts dissociation in traumatized adults and adolescents (Hébert et al., 2018). In path models spanning 620 men and women, cumulative childhood trauma was associated with affect dysregulation and sexual anxiety, which in turn predicted lower sexual satisfaction (Bigras et al., 2017). Among young women, both childhood maltreatment severity and difficulties in emotion regulation independently and negatively predicted sexual satisfaction (Rellini et al., 2012). PTSD is a pivotal mediator: PTSD symptoms mediate the CSA–revictimization link (Ullman et al., 2009), and trauma-related emotion dysregulation and maladaptive coping are among the strongest identified risk factors for revictimization (Scoglio et al., 2021).

These mechanisms likely operate differently by gender. Girls and women more consistently show internalizing trajectories — trauma symptoms, psychopathology, and suicide attempts — whereas boys and men more consistently show externalizing trajectories — behavioral problems, substance use, and disordered eating — following CSA (Lewis et al., 2016). Emotion regulation is the hinge: the same dysregulated arousal that becomes sexual aversion and distress in women may become sexual risk-taking, compulsivity, or substance-disinhibited sex in men (Hébert et al., 2018; Lewis et al., 2016). This is consistent with the finding that female survivors report greater trauma-related distress, including anxiety, depression, and post-trauma symptoms, while using more emotion-focused coping, with males reporting greater use of acceptance (Sigmon et al., 1997).

5.3. Sexual Self-Schemas and Cognitive-Affective Processing

Sexual self-schemas — cognitive generalizations about the sexual self that guide the processing of sexual information — provide a cognitive-affective bridge from trauma to sexual function. Women with CSA histories view themselves as less romantic and passionate than non-abused women, and this schematic difference is related to negative sexual affect during arousal independently of depression and anxiety (Meston et al., 2006). More embarrassed/conservative and less romantic/passionate schemas predict negative affect prior to exposure to sexual stimuli, which in turn predicts lower sexual satisfaction; negative affect partially mediates the CSA–satisfaction relationship (Rellini & Meston, 2011). For women with CSA, a lack of positive emotions related to sexuality — rather than greater negative emotions — appears most relevant to sexual health (Pulverman et al., 2018).

Comparable schematic research in men is nearly absent, which is itself an explanatory gap: if sexual self-concept is constructed through gendered cultural scripts — where female sexuality is relational and vulnerable to violation, and male sexuality is performance-oriented and agentic — the same abuse experience would be expected to distort self-schemas in sex-specific directions, with shame and aversion dominating in women and competence or entitlement distortions dominating in men (Bigras et al., 2020; Meston et al., 2006).

5.4. Attachment and Relational Functioning

Attachment theory offers a developmental account of why trauma disrupts sexuality. Adult attachment style, determined by childhood relationships with caregivers, affects the experience of romantic love and is substantially associated with affect-regulation strategies, nonintimate sexuality, eating disorders, and drinking motives (Brennan & Shaver, 1995). Anxious attachment in community samples predicts early first intercourse, more lifetime partners, more infidelity, and more sexual precautions — associations generally stronger in women (Bogaert & Sadava, 2002). Attachment schemas differentiate sexual desires and behaviors (Stephan & Bachman, 1999), and the behavioral systems perspective frames sex, attachment, and caregiving as interacting motivational systems in romantic relationships (Duschinsky, 2020; Mikulincer & Goodman, 2006). In the multigenerational abuse study, high-quality relationships with male peers predicted greater birth control efficacy in abused females, suggesting that emotionally deep relationships facilitate the "degeneralization" of males as sexual rather than relational objects (Trickett et al., 2011).

For gendered outcomes, attachment is a plausible differentiator because abuse damages the attachment-sex interface differently by gender: anxious-preoccupied patterns (more prevalent in women) may route trauma into sexual anxiety, approval-seeking, and revictimization, whereas dismissive-avoidant patterns (more prevalent in men) may route trauma into emotional distance, compartmentalized or compulsive sexuality, and reduced help-seeking (Bogaert & Sadava, 2002; Brennan & Shaver, 1995; Mikulincer & Goodman, 2006).

5.5. Sociocultural Scripts, Masculinity, and Coping

Sociocultural factors may be the strongest proximal drivers of gender divergence. Female survivors report greater trauma-related distress and use more emotion-focused coping, while male survivors report more acceptance — a pattern consistent with gendered emotional socialization (Sigmon et al., 1997). Among male survivors, abuse-related mental health problems persist for decades: in a population-based study of men, CSA was related to depressive symptoms, somatic symptom severity, and hostility nearly fifty years after the abuse, with the authors highlighting masculine norms as a relevant but under-measured construct (Easton & Kong, 2017). Notably, although the context and consequences of CSA are broadly similar for men and women in record-based samples, among male participants the number of abuse incidents, injury at the hands of a caregiver, and exposure to other traumas significantly explained mental health symptoms — suggesting that abuse severity parameters, not gender per se, may drive much of the apparent difference (Banyard et al., 2004).

The gender paradox in mental health outcomes — similar or even greater psychopathology risk in men relative to their low base rates — is documented in meta-analytic work: female victims had 2.43 times the odds of anxiety disorders relative to female non-victims, male victims 1.66 relative to male non-victims, but for anxiety symptoms the effect size was significantly higher in males (odds ratio 2.76 for males vs. 1.95 for females) (Amado et al., 2015). Reviews of meta-analyses conclude that CSA is a nonspecific risk factor for adult mental health difficulties with no consistent gender difference in outcomes, but with gender differences in perceived consequences (Hillberg et al., 2011). Male survivors of CSA show increased odds of mental disorders, with larger effects for many disorders and for suicide attempts compared with men without CSA (Turner et al., 2017). These data complicate any simple "women are more affected" narrative: men appear equally or differentially affected, but through channels — substance use, externalizing behavior, somatic complaints — that are less readily recognized as trauma sequelae (Lewis et al., 2016; Melamed et al., 2024). Physical and sexual abuse in childhood carries an over 70% increased risk of drug abuse in adulthood, with women at greater risk than men (Melamed et al., 2024).

5.6. Abuse Characteristics, Measurement, and Methodological Asymmetries

Part of the "gender difference" is methodological artifact. Prevalence measurement itself is gendered: in a population-based birth cohort, CSA was self-reported by 19.3% of males and 30.6% of females, while agency notifications captured far fewer cases — a disparity implying substantial false negatives, perhaps near 50%, in retrospective self-report (Fryers & Brugha, 2013; Mills et al., 2016). Gender differences in willingness to disclose, label, and report abuse systematically undercount male survivors (Banyard et al., 2004; Mills et al., 2016). Additionally, most studies — including most revictimization research — sample only women (Arata, 2002; Bigras et al., 2020; Scoglio et al., 2021), and the small number of studies including males (only three in one influential meta-analysis) severely limits estimates of gender effects (Gershon et al., 2008). When gender interactions are found, they are conditional: psychological outcomes were significantly stronger for males than females when abuse was unwanted, while negative reactions were greater for females across immediate, current, and lasting time frames (Gershon et al., 2008). Finally, the "gender difference" in dysfunction may partly reflect different base rates and measurement instruments; the same CSA–dysfunction meta-analysis found that effect size estimates differed substantially depending on the instruments used and the region of the sample (Wang et al., 2022); Table 1 summarizes these critical findings by domain and by gender.

6. Clinical Implications

The gendered pattern of consequences carries direct clinical implications. First, sexual health screening after childhood trauma should be gender-inclusive: men are systematically underrepresented in this literature, yet male survivors experience sexual dysfunction, compulsivity, and elevated pregnancy-related risk (Bigras et al., 2020; Gewirtz-Meydan & Opuda, 2022; Saewyc et al., 2004). Second, currently validated interventions for post-CSA sexual dysfunction have been evaluated only in women; specific interventions must be designed and tested for male survivors (Wang et al., 2022). Third, for women, mindfulness-based sex therapy and expressive writing treatments are particularly effective (Pulverman et al., 2018), and therapists should consider targeting affect dysregulation to reduce sexual anxiety and increase sexual satisfaction in survivors of cumulative trauma (Bigras et al., 2017). Fourth, the emotion-regulation and attachment pathways imply that couple-based and attachment-informed approaches may be valuable, given that abuse effects on sexuality are embedded in relational functioning (DiLillo et al., 2009; Mikulincer & Goodman, 2006; Trickett et al., 2011). Finally, the revictimization literature argues for early identification of survivors with PTSD, emotion dysregulation, and risky sexual behavior — the strongest modifiable risk factors — to interrupt cycles of revictimization (Scoglio et al., 2021; Ullman et al., 2009); Table 2 summarizes the resulting implications for practice, policy, and research.

7. Diversity Considerations in the Reviewed Literature

In keeping with Children and Youth Services Review's commitment to research that advances equity and social justice for children, youth, and families, this section examines the demographic, cultural, and conceptual diversity of the 65 sources synthesized in this review, and the implications of the gaps identified for interpreting and applying the review's conclusions.

Gender identity beyond the binary. This review's own organizing framework, a comparison of outcomes "between men and women," is itself a diversity limitation worth naming explicitly. Every source synthesized here operationalizes sex or gender as a binary male/female variable; none of the 65 studies reviewed examines sexual-health outcomes following childhood trauma in transgender, nonbinary, or other gender-diverse survivors as a distinct analytic group. Because minority-stress processes, gender-affirming or gender-incongruent embodiment, and distinct disclosure barriers may shape how childhood trauma is processed and expressed sexually, the review's central mechanistic account (that shared neurobiological embedding is filtered through gendered psychological and sociocultural systems) should be treated as a hypothesis about binary-gendered pathways specifically, not as a claim that has been tested, or is necessarily applicable, beyond them.

Sexual orientation. Sexual-minority survivors are addressed only indirectly in this literature. Blais et al.'s (2022) work on male survivors of military sexual trauma touches on a population with elevated sexual-minority representation, but no source in this synthesis directly stratifies childhood-trauma sexual-health outcomes by sexual orientation. Given that minority stress and compounded stigma plausibly interact with the emotion-regulation, attachment, and sociocultural mechanisms this review identifies as central to gendered divergence, this is a substantial gap rather than a peripheral one.

Race, ethnicity, and socioeconomic status. Several of the epidemiological anchors of this review, the original ACE study, national household surveys, and large probability samples, report on demographically broad but predominantly North American and Western European populations; a subset of sources (e.g., Mosack et al., 2010, on high-risk urban women, and the HIV-risk literature more broadly) engage socioeconomically marginalized samples, but explicit race- or ethnicity-stratified analysis of gendered sexual-health outcomes is largely absent, and no source in this synthesis systematically tests whether the gendered patterns described here are invariant across racial or ethnic groups or across socioeconomic strata.

Culture, nationality, and geography. Most of the review's mechanistic and cohort evidence originates from the United States, Australia, and New Zealand (e.g., the Christchurch and Dunedin cohorts, the Noll/Trickett multigenerational study), with the 29-country Global Study of Sexual Attitudes and Behaviors (Nicolosi et al., 2004) providing one of the few genuinely cross-national baselines used in this review, and it establishes baseline sexual-dysfunction prevalence rather than trauma-specific outcomes. The gendered mechanisms proposed here, particularly the sociocultural and masculinity-related pathways, are likely to be culturally contingent, and their applicability to non-Western, lower-resource, or more collectivist settings, where disclosure norms, family structure, and gender roles differ substantially, remains untested.

Age. The reviewed evidence concentrates on adolescents and adults in early-to-mid adulthood, supplemented by two sources specifically addressing sexual dysfunction in older adults (Laumann & Waite, 2008; Nicolosi et al., 2004) that establish baseline prevalence rather than trauma-specific effects; the sexual-health sequelae of childhood trauma among older survivors, whose abuse often occurred many decades before assessment, are addressed only indirectly through Easton and Kong's (2017) fifty-year follow-up of male survivors.

Implications for generalizability and future research. Because the review's central gendered framework was constructed entirely from binary-sex evidence concentrated in Western, high-income-country samples, its conclusions are best understood as characterizing documented patterns within that evidence base rather than universal sex-linked biology. Future research extending validated, multidimensional sexual-health measures to transgender and nonbinary survivors, to sexual-minority populations, to racially, ethnically, and socioeconomically diverse samples, and to non-Western cultural contexts is needed to determine which elements of the gendered account proposed here reflect durable biological or psychological mechanisms and which reflect the demographic and cultural boundaries of the studies conducted to date.

8. Gaps and Future Directions

Several gaps structure the future research agenda. Male survivors: prospective, adequately powered studies of male sexual outcomes following CSA, using validated multidimensional measures, are the single highest priority (Bigras et al., 2020; Gewirtz-Meydan & Opuda, 2022; Wang et al., 2022). Mechanistic testing: the neurobiological, cognitive-affective (self-schema), and relational (attachment) mechanisms require formal mediation and moderation tests with both sexes in the same designs (Agorastos et al., 2019; Bogaert & Sadava, 2002; Meston et al., 2006). Measurement: standardized definitions of CSA and of sexual outcomes, and improved disclosure-sensitive assessment, are needed to separate true gender differences from artifact (Mills et al., 2016; Scoglio et al., 2021; Wang et al., 2022). Longitudinal designs: most evidence remains cross-sectional; the few prospective studies — the Christchurch and Dunedin birth cohorts and the Noll/Trickett multigenerational study — show that adjustment for confounding and abuse characteristics substantially refines effect estimates (Fergusson et al., 2008; Guiney et al., 2024; Noll et al., 2003; Trickett et al., 2011). In the Christchurch cohort, CSA was associated with major depression, anxiety disorders, conduct disorders, substance abuse, and attempted suicide at ages 16 and 18 with odds ratios from 2.7 to 11.9, with risk increasing with abuse severity (Fryers & Brugha, 2013). Intersectionality: cultural context, sexual orientation, and socioeconomic conditions moderate both exposure and outcome, and current evidence is heavily Western (Bigras et al., 2020; Font & Maguire-Jack, 2016). Intervention trials in men: gender-specific treatment development, including trauma-informed sex therapy adapted to masculine norms, is urgently needed (Easton & Kong, 2017; Wang et al., 2022).

9. Conclusion

The sexual consequences of childhood trauma differ between men and women not because trauma affects one sex more than the other, but because identical neurobiological embedding is filtered through gendered psychological, relational, and cultural systems. Women show more consistent sexual dysfunction, aversion, and internalizing pathways, with well-characterized risk behavior and revictimization trajectories; men show real but inconsistently detected dysfunction, stronger relative elevations in externalizing and risk-taking pathways, and — strikingly — larger relative elevations in pregnancy involvement in population data. The evidence base itself is gendered, with male survivors systematically understudied and underrepresented in intervention research. A comprehensive account of why sexual consequences differ therefore requires not only better mechanistic science but a more equitable science — one that measures, includes, and treats both male and female survivors with equal rigor (Bigras et al., 2020; Gewirtz-Meydan & Opuda, 2022; Wang et al., 2022).
