Li W, Wang Y, Xu M, Liao Y, Zhou H, Ma H, Geng Q. Temporal Trends and Differences in Sexuality among Depressed and Non-Depressed Adults in the United States. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:14010. [PMID: 36360889 PMCID: PMC9654390 DOI: 10.3390/ijerph192114010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Revised: 10/26/2022] [Accepted: 10/26/2022] [Indexed: 06/16/2023]
Abstract
This study aimed to examine temporal trends and differences in sexuality between depressed and non-depressed adults aged 18-59 in the United States from 2005 to 2016. A total of 21,437 people (5432 with depression) were enrolled in this cross-sectional study. From 2005-2008 to 2013-2016, the average age at first sexual intercourse decreased, while the proportion of normal frequency of sexual activity and heterosexual sexual orientation increased among all the participants. Some differences in sexuality were found between the depressed and non-depressed groups. The average age at first sexual intercourse (p < 0.001), the proportion of normal frequency of sexual activity (p < 0.001), and heterosexual sexual orientation (p < 0.001) were lower in depressed participants, and the differences did not change over time (pfor trend = 0.926 of average age at first sexual intercourse, pfor trend = 0.823 of normal frequency of sexual activity, pfor trend = 0.926 of heterosexual sexual orientation). Moreover, these differences were associated with marital status (pfor interaction < 0.001 by average age at first sexual intercourse), employment status (pfor interaction < 0.001 by average age at first sexual intercourse), education status (pfor interaction = 0.023 by heterosexual sexual orientation) and family income status (pfor interaction = 0.013 by average age at first sexual intercourse and pfor interaction = 0.017 by normal frequency of sexual activity). In conclusion, the study found that the age at first sexual intercourse decreased and the frequency of sexual intercourse increased in all the participants, and differences in sexuality between depressed and non-depressed participants were present; however, these differences had no further increase or decrease during the 12-year period. These differences were associated with marital status, employment status, education status, and family income status. These findings show differences in sexuality between depressed and non-depressed patients but are somewhat different from previous studies; the results may provide directions for future research and social work.

Abstract
Objective: This study examined the state of mental health, partnerships, and sexual activity of German university students after the third wave of the COVID-19 pandemic. Participants and methods: In June and July 2021, 928 students (23.6 years; 63.5% female) from four universities in Germany participated in an online survey that assessed depressive and anxiety symptoms as well as data on partnerships and sexuality. Results: Of the students, 56.4% were above the cutoff for clinically relevant depressive symptoms and 35.7% were above the cutoff for clinically relevant anxiety symptoms. Female gender, higher academic-related stress, lower financial resources, higher strain due to COVID-19, and more loneliness were associated with more severe symptoms. A quarter of the students each reported an improvement or deterioration in their partnerships. Conclusions: Student mental health appears to be worse compared to pre-pandemic and first wave data. It should be examined whether symptoms decrease when universities reopen.

Abstract
Background Though many women report sexual arousal difficulties, the mechanisms driving these difficulties are unclear. Sexual response relies on a host of psychophysiological processes that have bidirectional relationships with inflammation. Additionally, chronic inflammation may impair genital blood flow, which in turn may impact sexual arousal. C-reactive protein (CRP) is an acute-phase marker of inflammation produced in response to cytokine signaling throughout the body, which makes it a useful marker of systemic inflammation. Aim The present study examined interactions between inflammation and women's sexual arousal. Methods CRP, self-reported frequency of partnered sexual activity, and subjective and vaginal arousal were assessed in 91 healthy, pre-menopausal women. Data were collected during a single laboratory session. Main outcome measures Subjective sexual arousal and vaginal pulse amplitude (a measure of vaginal arousal) were the main outcome measures. Results Change in subjective sexual arousal in response to a sexual film was unaffected by baseline CRP and sexual frequency. However, there were significant interactions between inflammation and sexual frequency in predicting vaginal arousal during the sexual film. Among women reporting more frequent sexual activity, higher CRP predicted lower magnitude arousal response and longer time to maximum vaginal arousal. Among women reporting less frequent sex, higher CRP predicted shorter time to maximum arousal and greater magnitude of arousal response. Controlling for cortisol strengthened the effects seen for time to maximum vaginal arousal but weakened those observed for percent change. Conclusions Among healthy young women, higher CRP may be associated with vaginal arousal, but not subjective sexual arousal. Specifically, our results suggest that higher baseline CRP is associated with lower genital sexual arousal for women who have sex frequently, which is consistent with clinical evidence that elevated inflammation can be detrimental to sexual function. Among healthy young women, higher CRP may be associated with vaginal sexual arousal, but not subjective sexual arousal. Frequency of sexual activity interacts with CRP levels to contribute to vaginal arousal in healthy women. Higher CRP predicted lower genital sexual arousal in women who engage in sexual activity more than once a week. However, higher CRP predicted greater genital sexual arousal in women who engage in sexual activity less than once a week.

Abstract
Objective Sexual activity is a fundamental human function with short-term and long-term emotional, social, and physical benefits. Yet within healthcare, sexuality has been marginalized and many HCPs are unaware of its beneficial implications for immediate and long-term health. Methods To challenge this assumption we combined the data that already had been collected by the authors with an extensive search of articles on the various health benefits of sexual activity. The results of this process are displayed according to short-term, intermediate-term, and long-term benefits with some explanation about potential causal relationships. Results For the time being, it cannot yet be proved that "good sex promotes good health" since good health also favors good sex. Conclusions Despite lacking such convincing evidence, the article concludes with recommendations for the relevant professions. The balance of research supports that sexuality anyhow deserves greater attention among HCPs and that sexuality research needs better integration within health research.

Abstract
INTRODUCTION A novel coronavirus (COVID-19) reached pandemic levels by March 11th, 2020, with a destructive impact across socioeconomic domains and all facets of global health, but little is known of its impact on sexual health. OBJECTIVE To review current knowledge on sexual health-related containment measures during pandemics, specifically COVID-19, and focus on 2 main areas: intimacy and relational dynamics and clinical effects on sexual health. METHODS We carried out a literature search encompassing sexual health and pandemic issues using Entrez-PubMed and Google Scholar. We reviewed the implications of the COVID-19 pandemic on sexual health regarding transmission and safe sex practices, pregnancy, dating and intimacy amid the pandemic, benefits of sex, and impact on sexual dysfunctions. RESULTS Coronavirus transmission occurs via inhalation and touching infected surfaces. Currently, there is no evidence it is sexually transmitted, but there are sexual behaviors that pose a higher risk of infectivity due to asymptomatic carriers. Nonmonogamy plays a key role in transmission hubs. New dating possibilities and intimacy issues are highlighted. Sexual activity has a positive impact on the immune response, psychological health, and cognitive function and could mitigate psychosocial stressors. COVID-19 pandemic affects indirectly the sexual function with implications on overall health. CONCLUSION Increased awareness of health-care providers on sexual health implications related to the COVID-19 pandemic is needed. Telemedicine has an imperative role in allowing continued support at times of lockdown and preventing worsening of the sexual, mental, and physical health after the pandemic. This is a broad overview addressing sexual issues related to the COVID-19 pandemic. As this is an unprecedented global situation, little is known on sexuality related to pandemics. Original research is needed on the topic to increase the understanding of the impact the current pandemic may have on sexual health and function. Pennanen-Iire C, Prereira-Lourenço M, Padoa A, et al.

Abstract
Past research has found menstrual-cycle-related changes in functional immune response; we examined if sexual activity also changed markers of immune defense. We followed 32 naturally cycling women (15 sexually active with a partner ≥ 1 time/week, 17 sexually abstinent for the last four months) over one menstrual cycle. Participants provided serum and saliva samples at menses and ovulation, and additional saliva samples at midfollicular and midluteal phases. At each phase, participants also self-reported symptoms associated with colds, flu, pain, menstrual discomfort, and premenstrual syndrome. We tested saliva and serum for ability to kill Escherichia coli or Candida albicans, and serum for complement protein activity. For serum-mediated pathogen killing, among sexually active women only, there was a significant midcycle decrease in killing of E. coli. For saliva-mediated pathogen killing, among abstinent women only, there was a significant midcycle decrease in killing of E. coli, and midcycle increase in killing of C. albicans. Sexually active women had significantly lower complement activity than abstinent women overall. Finally, both groups reported lower physical symptoms at midcycle and higher symptoms at menses. There may be important differences in immune function between healthy women who are sexually active versus abstinent. Further replication is warranted.

Abstract
Depression is a pervasive mental health concern; thus, it is important to identify modifiable factors associated with reducing depressive symptoms across time. Using 1,876 heterosexual couples assessed annually across 4 years from the Panel Analysis of Intimate Relationships and Family Dynamics (Pairfam) study, time-varying covariate growth models tested if sexual and relationship satisfaction were linked with shifts in trajectories of depressive symptoms across time. For both men and women, higher sexual and relationship satisfaction scores were significantly associated with decreasing their own depressive symptom trajectories, but only relationship satisfaction was linked with their partners' depressive symptom trajectories. Potential clinical implications include the treatment of depressive symptoms by making changes across time in their own relationship satisfaction and sexual satisfaction.

Abstract
Sexual violence is associated with increased risk of HIV acquisition/transmission in women. Forced sex can result in physical trauma to the reproductive tract as well as severe psychological distress. However, immuno-biological mechanisms linking sexual violence and HIV susceptibility are incompletely understood. Using the Women’s Interagency HIV Study repository, a total of 77 women were selected to form 4 groups, stratified by HIV serostatus, in the following categories: 1) no sexual abuse history and low depressive symptom score (below clinically significant cut-off, scores <16) (Control); 2) no sexual abuse history but high depressive symptom score, ≥16 (Depression); 3) chronic sexual abuse exposure and low depressive symptom score (Abuse); 4) chronic sexual abuse exposure and high depressive symptom score (Abuse+Depression). Inflammation-associated cytokines/chemokines/proteases (TNF-α, IL-6, IL-1α, IL-1β, TGF-β MIP-3α, IP-10, MCP-1, Cathepsin B), anti-inflammatory/anti-HIV mediators (Secretory leukocyte protease inhibitor (SLPI), Elafin, beta defensin 2 (HBD2), alpha defensins (HNP 1–3), Thrombospondin (TSP-1), Serpin A1, A5, Cystatin A, B), and wound-healing mediators (Gro-α, VEGF, PDGF, EGF, FGF, IGF), were measured in cervical-vaginal lavage (CVL) using ELISA. Linear regression was used to model association of biomarkers with depression and abuse as predictor variables; the interaction between depression and abuse was also tested. Anti-HIV activity in CVL was tested using TZM-bl indicator cell line. In HIV-uninfected women, median levels of IL-6 (p = 0.04), IL-1α (p<0.01), TGF-β (p = 0.01), IP-10 (p = <0.01), PDGF (p<0.01) and FGF (p<0.01), differed significantly between groups. Specifically, an association was found between chronic sexual abuse and increased IL-1α (p<0.01), MIP-3α (p = 0.04), IP-10 (p<0.01), Serpin B1 (p = 0.01), FGF (p = 0.04) and decreased TGF-β (p<0.01), MCP-1 (p = 0.02), PDGF (p<0.01). Further, there was evidence of significant interactions between chronic sexual abuse and current depression for IL-1α, IP-10, Serpin A1, Cystatin B, and FGF. In HIV-infected women, median levels of TNF-α (p<0.01), IL-6 (p = 0.05), MIP-3α (p<0.01), and MCP-1 (p = 0.01), differed significantly between groups. Specifically, an association was found between chronic sexual abuse and increased MCP-1 (p = 0.03), Gro-α (p = 0.01) and decreased TNF-α (p<0.01), IL-1α (p = 0.02), MIP-3α (p<0.01) and Cathepsin B (p = 0.03). Current depressive symptoms were associated with significantly decreased MIP-3α (p<0.01). There was evidence of significant interactions between chronic sexual abuse and current depression for MCP-1 and FGF. No significant differences were observed in anti-HIV activity among all eight groups. Heat-map analyses revealed distinct immune network patterns, particularly in the Abuse groups for both HIV-infected and uninfected women. Our data indicates a complex relationship between chronic sexual abuse exposure, depressive symptoms, and FRT immune mediators that are also affected by HIV status. Association of chronic sexual abuse with increase in inflammation-associated cytokine/chemokine expression, along with impaired wound-healing associated growth-factors can create a microenvironment that can facilitate HIV infection. Evaluation of longitudinal changes in exposures and biomarkers are needed to untangle the immuno-biological mechanisms that may put women who endure life-long sexual abuse at increased risk for HIV.

Abstract
Wound healing is a highly complex life-important repair process triggered by plenty of local and/or systemic organ and tissue damaging events, such as an acute surgical invasion, accidental organ and tissue damages, acute and chronic diseases, aggressive local and systemic therapeutic approaches (e.g. irradiation and systemic chemotherapy). Individual health condition determines over the quality of wound healing. Impaired wound healing, in turn, may lead, for example, to post-surgical complications frequently observed in elderly, chronic ulcers in diabetic patients, hindered and ineffective pain management, etc. However, these well-acknowledged examples are just the tip of the iceberg. The entire spectrum of potential consequences is much broader. Therefore, all the aspects of wound healing need to receive a dedicated attention of many specialised medical fields and healthcare as a whole. In contrast, there is still strongly limited knowledge collected regarding the molecular and cellular mechanisms underlying the physiological versus impaired wound healing. The contents of this article might be of great importance for multi-professional considerations as well as for the experts working in specific fields such as clinical proteomics, general practice, laboratory medicine, surgery including plastic surgery and aesthetic medicine, gerontology, psychology, diabetology, endocrinology, oncology, cardiovascular disease, radiology, and healthcare economy. SIGNIFICANCE The contents of this article are strongly motivated by the particular value of wound healing quality for medical care and might be of great importance for multi-professional considerations and experts working in specialised fields: predictive and preventive medicine, general practitioners, laboratory medicine, surgery including plastic surgery and aesthetic medicine, gerontology, psychology, diabetology, endocrinology, oncology, cardiovascular disease, radiology, and healthcare economy. The article is aiming at both educational and scientific purposes: on one side it summarises comprehensive information available regarding wound healing mechanisms and molecular pathways involved. On the other side the article provides highly innovative hypotheses for multi-professional considerations relevant for several research fields which may potentially advance medical services in the close future such as clinical proteomics and multi-omics.

Abstract
Background Mental resilience can be seen as a trait that enables an individual to recover from stress and to face the next stressor with optimism. People with resilient traits are considered to have a better mental and physical health. However, there are limited data available assessing the relationship between resilient individuals and their perspective of their health and immune status. Therefore, this study was conducted to examine the relationship between mental resilience, perceived health, and perceived immune status. Methods A total of 779 participants recruited at Utrecht University completed a questionnaire consisting of demographic characteristics, the brief resilience scale for the assessment of mental resilience, the immune function questionnaire (IFQ), and questions regarding their perceived health and immune status. Results When correcting for gender, age, height, weight, smoker status, amount of cigarettes smoked per week, alcohol consumption status, amount of drinks consumed per week, drug use, and frequency of past year drug use, mental resilience was significantly correlated with perceived health (r=0.233, p=0.0001), perceived immune functioning (r=0.124, p=0.002), and IFQ score (r=−0.185, p=0.0001). Conclusion A significant, albeit modest, relationship was found between mental resilience and perceived immune functioning and health.

Abstract
Although testosterone (T) has been characterized as universally immunosuppressive across species and sexes, recent ecoimmunology research suggests that T's immunomodulatory effects (enhancing/suppressing) depend on the organism's reproductive context. Very little is known about the immune effects of T in healthy females, and even less about how reproductive effort modulates the immune effects of T in humans. We investigated how the interaction between endogenous T and sexual activity predicted menstrual cycle-related changes in several measures of immunity: inflammation (indexed by interleukin-6, IL-6), adaptive immunity (indexed by immunoglobulin A, IgA), and functional immunity (indexed by bactericidal assay). Thirty-two healthy women (sexually abstinent, N=17; sexually active with one male partner, N=15) provided saliva samples at four points in the menstrual cycle: menses, follicular, ovulation, and luteal phases. Among sexually abstinent women, T was positively associated with IL-6 across the cycle; for sexually active women, however, T was positively associated with IL-6 in the luteal phase only, and negatively associated with IL-6 at ovulation. High T predicted higher IgA among women who reported infrequent intercourse, but lower IgA among women who reported very frequent intercourse. Finally, across groups, T was positively associated with greater bacterial killing at menses, but negatively associated in the luteal phase. Overall, rather than being universally immunosuppressive, T appeared to signal immunomodulation relevant to reproduction (e.g., lowering inflammation at ovulation, potentially preventing immune interference with conception). Our findings support the hypothesis that the immunomodulatory effects of endogenous T in healthy females depend on sexual and reproductive context.

Abstract
OBJECTIVE To examine differences in inflammation markers in sexually active versus abstinent women and observe changes in inflammation markers across the menstrual cycle. Cycle-related immune fluctuations may have evolved to reduce interference with conception. If so, reproductively active (i.e., sexually active) women should show the most variability in cytokine expression. DESIGN Participants provided serum samples at menses and ovulation (from which cytokines were assayed) and saliva samples at menses and during follicular, ovulation, and luteal phases (from which C-reactive protein [CRP] was assayed). Participants self-reported intercourse frequency during the study. SETTING Academic research laboratory. PATIENT(S) Thirty-two healthy, naturally cycling premenopausal women (sexually active, n = 15; abstinent, n = 17). INTERVENTION(S) Observational study. MAIN OUTCOME MEASURE(S) Levels of proinflammatory cytokines (interleukin-6 [IL-6], interferon γ [IFN-γ], tumor necrosis factor-α [TNF-α]), an anti-inflammatory cytokine (interleukin-4 [IL-4]), and a marker of total inflammation (CRP). RESULT(S) Sexually active women had higher levels of all of the immune markers measured, including both pro- and anti-inflammatory cytokines, than abstinent women. Relative to sexually active women, abstinent women had less change across the menstrual cycle in levels of CRP. Among sexually active women, higher intercourse frequency predicted greater midcycle decreases in CRP, IL-6, and IFN-γ and midcycle increases in IL-4. CONCLUSION(S) Sexual activity may stimulate a complex interaction between pro- and anti-inflammatory cytokines that subsequently drives midcycle declines in inflammation.

Abstract
Inflammation in healthy sexually active women decreased at midcycle, around ovulation, which may have evolved to promote conception. Background and objectives: We examined a mechanism that may coordinate trade-offs between reproduction and immune response in healthy women, namely, changes in inflammation across the ovarian cycle. Methodology: We investigated C-reactive protein (CRP), an inflammation marker, across two consecutive ovarian cycles in 61 Bolivian women. Participants provided saliva samples every other day, and dried blood spots on 5–6 days spread across weeks 2–3 of each cycle. Cycles were characterized as ovulatory/anovulatory based on profiles of reproductive hormones. Participants also reported whether they were sexually partnered with a male or sexually abstinent during the study. Results: High early-cycle, but not late-cycle, CRP was associated with anovulation. High inflammation at the end of one cycle was not associated with anovulation in the subsequent cycle. Among ovulatory cycles, women with sexual partners had significantly lower CRP at midcycle, and higher CRP at follicular and luteal phases; in contrast, sexually abstinent women had little cycle-related change in CRP. In anovulatory cycles, partnership had no effect on CRP. CRP varied significantly with socioeconomic status (higher in better-off than in poorer women). Conclusions and implications: These findings suggest that the cycle-specific effect of inflammation on ovarian function may be a flexible, adaptive mechanism for managing trade-offs between reproduction and immunity. Sociosexual behavior may moderate changes in inflammation across the ovarian cycle, suggesting that these shifts represent evolved mechanisms to manage the trade-offs between reproduction and immunity. Clinically, these findings support considering both menstrual cycle phase and sexual activity in evaluations of pre-menopausal women’s CRP concentrations.

Abstract
OBJECTIVES Although there is nowadays wide agreement on bacteria being the main etiologic agents of periodontal disease, their sole presence cannot damage periodontal tissues in all subjects. This suggests that an individual response and an adaptation to a certain quantity of bacterial biofilm can occur without the disease progressing and vice versa. Depression, stress and anxiety have not been confirmed yet as risk conditions but, in some observational studies, they have been identified as potential risk factors of periodontal disease. The current study aims at investigating the role which these psychological disorder have in the onset and progression of advanced stage periodontitis. MATERIALS AND METHODS The case selection was carried out by means of clinical and radiological periodontal assessment involving a total of 108 subjects, both male and female, aged between 24 and 67. Patients were then divided in two groups of 54 patients each: the first group included patients with severe periodontal disease, the second group was formed by periodontally healthy subjects. Clinical assessment was performed by a sole examiner who selected and divided periodontopathic patients from non-periodontopathic ones. From the current study were excluded: patients with systemic pathologies; smokers; patients taking antidepressant drugs; pregnant women. RESULTS For what concerns depression, in the group of periodontopathic patients it was found that the 62.5% of them were depressed, against the 38.86% in the group of periodontally healthy subjects. For the other two psychological conditions taken into consideration, anxiety and stress, it emerged a different percentage of subjects with anxiety in the periodontal group (31.48%) against healthy controls (20.37%). CONCLUSIONS For each of the psychological variables considered (depression, anxiety, stress), a significant correlation could be observed with periodontal disease, it can be therefore be suggested that the importance these disturbs have in the onset and progress of the dental disease which supports the existing available data in literature. The innovative aspect of this research was the focus on the assessment of compliance, monitoring the ability of periodontal patients to follow oral hygiene instructions aiming at the improving and keeping their own periodontal condition, even though this takes more time than the control group.

Abstract
Several studies have documented shifts in humoral immune parameters (e.g., immunoglobulins) across the menstrual cycle in healthy women. It is thought that these shifts may reflect dynamic balancing between reproduction and pathogen defense, as certain aspects of humoral immunity may disrupt conception and may be temporarily downregulated at ovulation. If so, one could expect maximal cycle-related shifts of humoral immunity in individuals invested in reproduction - that is, women who are currently sexually active - and less pronounced shifts in women who are not reproductively active (i.e., abstinent). We investigated the interaction of sexual activity, menstrual cycle phase, and humoral immunity in a sample of 32 healthy premenopausal women (15 sexually active, 17 abstinent). Participants provided saliva samples during their menses, follicular phase, ovulation (as indicated by urine test for LH surge), and luteal phase, from which IgA was assayed. Participants also provided blood samples at menses and ovulation, from which IgG was assayed. Sexually active participants provided records of their frequency of sexual activity as well as condom use. At ovulation, sexually active women had higher IgG than abstinent women (d=0.77), with women reporting regular condom use showing larger effects (d=0.63) than women reporting no condom use (d=0.11). Frequency of sexual activity predicted changes in IgA (Cohen's f(2)=0.25), with women reporting high frequency of sexual activity showing a decrease in IgA at ovulation, while women reporting low frequency or no sexual activity showing an increase in IgA at ovulation. Taken together, these findings support the hypothesis that shifts in humoral immunity across the menstrual cycle are associated with reproductive effort, and could contribute to the mechanisms by which women's physiology navigates tradeoffs between reproduction and immunity.

[PMID: 26385401 DOI: 10.1016/j.fertnstert.2015.09.001] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2015] [Revised: 09/01/2015] [Accepted: 09/01/2015] [Indexed: 01/31/2023]
Abstract
OBJECTIVE To investigate if sexual activity moderated menstrual cycle-related shifts in cytokines associated with T-helper type 1 (TH1) cells (e.g., interferon [IFN] γ) and T-helper type 2 (TH2) cells (e.g., interleukin [IL] 4). Immune activity shifts across the menstrual cycle, with higher follicular-phase TH1-cell activity but higher luteal-phase TH2-cell activity. Little is known about how social behaviors alter TH1-TH2 ratios, despite evidence that psychosocial factors can influence immunity. Of particular interest is how sexual activity influences immune responses that may support conception, such as the TH1-TH2 balance. DESIGN Participants provided saliva samples at four time points (menstrual, follicular, ovulatory, and luteal phases), which were assayed by means of ELISA. SETTING Academic laboratory. PARTICIPANT(S) Thirty healthy premenopausal women (16 sexually abstinent, 14 sexually active) not taking hormonal or immunoactive medications. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Salivary E2, P, IFN-γ, and IL-4. RESULT(S) Sexually active, but not abstinent, women were significantly more likely to express TH2-like cytokine ratios (IFN-γ < IL-4) in the luteal phase than in other phases. Similarly, sexually active women had significantly higher P, and higher P-E2 ratios, in the luteal phase than did abstinent women. The P-E2 ratio mediated menstrual variations in cytokine ratios in sexually active women. CONCLUSION(S) These results support the hypothesis that shifts in immune response across the menstrual cycle may reflect tradeoffs between reproduction and immunity. These findings point to the need for further research on the interaction between sexual behavior, the menstrual cycle, and immune response.
