RESUMEN

Age at first sexual intercourse (AFS) and lifetime number of sexual partners (NSP) may influence the pathogenesis of uterine leiomyoma (UL) through their associations with hormonal concentrations and uterine infections. Leveraging summary statistics from large-scale genome-wide association studies conducted in European ancestry for each trait (NAFS = 214,547; NNSP = 370,711; NUL = 302,979), we observed a significant negative genomic correlation for UL with AFS (rg = -0.11, P = 7.83×10-4), but not with NSP (rg = 0.01, P = 0.62). Four specific genomic regions were identified as contributing significant local genetic correlations to AFS and UL, including one genomic region further identified for NSP and UL. Partitioning SNP-heritability with cell-type-specific annotations, a close clustering of UL with both AFS and NSP was identified in immune and blood-related components. Cross-trait meta-analysis revealed 15 loci shared between AFS/NSP and UL, including 7 novel SNPs. Univariable two-sample Mendelian randomization (MR) analysis suggested no evidence for a causal association between genetically predicted AFS/NSP and risk of UL, nor vice versa. Multivariable MR adjusting for age at menarche or/and age at natural menopause revealed a significant causal effect of genetically predicted higher AFS on a lower risk of UL. Such effect attenuated to null when age at first birth was further included. Utilizing participant-level data from the UK Biobank, one-sample MR based on genetic risk scores yielded consistent null findings among both pre-menopausal and post-menopausal females. From a genetic perspective, our study demonstrates an intrinsic link underlying sexual factors (AFS and NSP) and UL, highlighting shared biological mechanisms rather than direct causal effects. Future studies are needed to elucidate the specific mechanisms involved in the shared genetic influences and their potential impact on UL development.

RESUMEN

The penis is the primary site of HIV acquisition in heterosexual men. Elevated penile inflammatory cytokines increase sexual acquisition risk, and topically applied cytokines enhance foreskin HIV susceptibility in an explant model. However, the impact of penile-vaginal sex on these immune parameters is undefined. Heterosexual couples were recruited to the Sex, Couples and Science (SECS) Study, with the collection of penile swabs, semen, cervico-vaginal secretions, and blood after a period of abstinence, and repeated sampling up to 72 hours after either condomless (n = 30) or condom-protected (n = 8) penile-vaginal sex. Soluble immune parameters were quantified by multiplex immunoassay. Co-primary immune endpoints were penile levels of IL-8 and MIG, cytokines previously linked to penile HIV acquisition. One hour after sex there were dramatic increases in penile IL-8 and MIG levels, regardless of condom use, with a gradual return to baseline by 72 hours; similar patterns were observed for other chemoattractant chemokines. Penile cytokine changes were similar in circumcised and uncircumcised men, and repeated measures ANOVA and ANCOVA models demonstrated that the degree of change after condomless sex was explained by cytokine levels in their partners' cervico-vaginal secretions. This may have important implications for the biology of penile HIV acquisition.

RESUMEN

RESEARCH QUESTION: What is the fecundity rate among fertile couples, and which factors influence it? DESIGN: Retrospective study of all puerperae attending Cruces University Hospital Human Reproduction Unit over 9 months. An anonymous questionnaire was circulated to all patients, and 2510 valid completed questionnaires were collected. The main inclusion criterion was natural conception resulting in delivery. Pregnancies resulting from ART and contraceptive method failure were excluded. Investigated parameters were time to pregnancy, age and smoking (in women and men), previous pregnancies and intercourse frequency. A mathematical formula was developed to predict the per-month fecundity rate (PMFR). RESULTS: The cumulative fecundity rate was 29.08%, 54.26%, 68.61%, 89.88%, 96.95% and 98.63% (at 1, 3, 6, 12, 24 and 36 months); between 12 and 36 months, the average PMFR ranged from 8.53-7.48%. Only 1.68% of pregnancies occurred between 24 and 36 months, and only 1.37% thereafter. The best fecundity markers were obtained in the group who had sexual intercourse seven to eight times a week. Women and men younger than 25 years had lower fecundity markers than those aged between 25 and 40 years. CONCLUSIONS: Fertile couples have a non-negligible per-month fecundity rate between 12 and 36 months, which should be considered when planning fertility studies. The lower fecundity rate observed in women and men aged younger than 25 years deserves more study. Coital frequencies of more than two or three times a week did not affect the fecundity rate and was better with frequencies of seven to eight times a week.

RESUMEN

BACKGROUND: Patients with premature ejaculation (PE) are often concerned and distressed about their sexual performance. Hence, they may be more willing to exploit their refractory period to employ sexual coping strategies in order to improve their unsatisfactory sexual intercourse compared with patients without PE. AIM: The study sought to verify the sexual coping strategies of patients with PE in the daily sexual activities. METHODS: We included both patients with PE and individuals without PE and analyzed their sexual behaviors and attitudes by means of detailed interviews and questionnaires. OUTCOMES: The main outcomes were perceived intravaginal ejaculatory latency time recording, Premature Ejaculation Diagnostic Tool score, and sexual frequency, attitudes, and behavior log. RESULTS: A total of 182 young patients with PE (age 31.2 ± 6.2 years) and 92 individuals without PE (age 30.7 ± 5.1 years) were included in the study. A total of 53.3% of patients with PE vs 17.4% of individuals without PE reported engaging in multiple sexual intercourse sessions within a single day in the past 4 weeks. PE patients who engaged in multiple intercourse sessions displayed better performance during the second attempt but performed poorly compared with individuals without PE. Scores for the first attempt in PE vs second attempt in individuals with PE vs without PE were the following: intravaginal ejaculatory latency time, 2.4 ± 1.6 vs 4.8 ± 5.7 vs 9.9 ± 9.4 (P < .001); Premature Ejaculation Diagnostic Tool, 14.9 ± 3.1 vs 12.7 ± 4.8 vs 5.2 ± 2.5 (P < .001); satisfaction, 2.9 ± 1.0 vs 3.1 ± 0.8 vs 3.7 ± 1.4 (P < .001). A total of 57.1% of patients held a negative attitude toward precoital masturbation, for reasons such as a reduced sexual desire (21.2%), the belief that masturbation is harmful (17.6%), concerns about erectile function (15.7%), fatigue (9.8%), and other mixed reasons (35.3%). CLINICAL IMPLICATIONS: Engaging in multiple intercourse sessions within a day is more common among the young PE population, and using precoital masturbation as a coping strategy is not universally applicable among patients with PE. STRENGTHS AND LIMITATIONS: This is the first study to explore symptom-coping strategies in patients with PE compared with individuals without PE. However, the conclusions cannot be generalized to the entire male population. CONCLUSION: Patients with PE, compared with individuals without PE, are more inclined to engage in multiple sexual intercourse sessions within a single sexual session, likely in an attempt to compensate for their first unsatisfactory sexual encounter. Moreover, the majority of patients with PE here studied hold a negative attitude toward using precoital masturbation as a coping strategy for symptoms.

RESUMEN

BACKGROUND: Among the plethora of urogynecological conditions possibly affecting women, some of them, less explored, have significant impacts on sexological and psychological health, with a mutual influence. AIM: The aim of this study was to investigate the sexological and psychological correlates of four urogynecological pathologies in a sample of women of childbearing age: overactive pelvic floor, vulvodynia, postcoital cystitis, and interstitial cystitis. Women cured of these conditions were also included, to assess the same aspects after the remission of physical symptoms. METHODS: We recruited 372 women with an average age of 33.5 years through an online platform shared by a popular forum for women with urogynecological pathologies between March and May 2021. The participants filled out a socio-anamnestic questionnaire and a set of psychometric tests. OUTCOMES: Participant data were collected by use of the Patient Health Questionnaire-9, Generalized Anxiety Disorder-7, Toronto Alexithymia Scale-20, Female Sexual Function Index, and Orgasmometer-F, and the SPSS (Statistical Package for Social Sciences) v.26 was used for data analysis. RESULTS: Overactive pelvic floor was reported by 66.4% of the women, vulvodynia by 55%, postcoital cystitis by 58.8%, and interstitial cystitis by 8.3%, and these conditions were often comorbid with each other, with 9.4% and 7% of women reporting having suffered psychological and sexual abuse, respectively. The presence of past abuse was correlated with overactive pelvic floor (P < .05), vulvodynia (P < .01), and major depression (P < .01). Significantly more depression occurred in women with vulvodynia than in the other subgroups (P < .05), except for women with only an overactive pelvic floor. There was no difference between the subgroups in the occurrence of alexithymia, sexual function, and orgasm (P < .05). Interestingly, the prevalence of sexual dysfunction increased in cured women. CLINICAL IMPLICATIONS: The lack of significant differences, except for depression, between the pathological subgroups suggests a similar clinical and psychological relevance of the four pathologies studied. The persistence of sexual dysfunctions in cured women may be related to a residual dysfunctional relational modality with the partner. STRENGTHS AND LIMITATIONS: The evaluation of both psychological and sexological variables in a group of less-explored urogynecological conditions represents a strength of this study, while a lack of a face-to-face assessment could represent a limitation. CONCLUSION: The results of the present study should promote psychosexological interventions in women with these diseases, both during the pathological state and after remission.

RESUMEN

Studies continue to underscore the profound impact of sexual violence on women's health. Yet, little is known about the impact, via a complex matrix of behavioural and social factors, of first intercourse, namely forced non-consensual on HIV status, particularly among sexually active women (SAW) in low-income countries where HIV prevalence remains high. Using a national sample from Eswatini, we employed multivariate logistic regression modelling to estimate the associations between forced first-sex (FFS), subsequent sexual behaviour and HIV status among 3555 SAW aged from 15 years to 49 years. The results found that women who experienced FFS had a greater number of sexual partners compared to those who had never experienced FFS (aOR = 2.79, p < .01), although there were no significant differences in condom use, early sexual debut and casual sex involvement between these two groups. FFS remained significantly associated with a higher risk of having HIV (aOR = 1.70, p < .05) even after controlling for risky sexual behaviours and various other factors. These findings further reinforce the relationship between FFS and HIV, and suggest that addressing sexual violence is a critical component of HIV prevention among women in low-income countries.

RESUMEN

The current study investigated the correlates of post-coital dysphoria (PCD) in men and women. Moreover, the study explored the PCD prevalence in the sexual contexts of a relationship, casual sex, and masturbation. An online survey was completed by 156 participants, 51 males and 105 females. All participants were over 18 and have had sex in and out of relationships, as well as having engaged in masturbation. Results showed that PCD was prevalent in each of the three sexual contexts, for both males and females. Furthermore, some previously identified correlates were replicated and found to be statistically significant predictors of PCD. A previously unexplored variable that was also found to significantly predict PCD were negative attitudes toward masturbation. The current research established that PCD occurs in multiple sexual contexts - something previously unknown. Prevalence rates of PCD after sex within a relationship, casual sex, and masturbation, for males were 21.6, 49 and 72.5, respectively. For females, prevalence rates were 11.4, 77.1 and 51.4%, respectively. Additionally, it identified which factors predict the experience of PCD for each of the different sexual contexts for each gender. This has potentially huge implications in formulating a focus for the treatment of PCD, dependent upon the gender and sexual context it is experienced in.

RESUMEN

Research has repeatedly shown marked differences in men's and women's sexual response patterns; genital response in men tends to be elicited by cues that correspond to their sexual preference (preferred gender), while women's genital response is less sensitive to gender cues and more sensitive to the presence and intensity of other sexual cues (e.g., sexual activities). We tested whether the cue of copulatory movement in a general sexual context elicited a genital response in androphilic women but not in gynephilic men. If so, women should react to stimuli depicting not only the non-preferred gender but also other animal species differing in phylogenetic distance to humans. We studied the genital and self-reported arousal of 30 gynephilic men and 28 androphilic women to two sexual videos depicting penetrative human sexual intercourse (female-male and female-female) and nine videos depicting animal copulation. Neither women nor men showed genital or subjective sexual arousal to non-human sexual stimuli. Moreover, both sexes demonstrated a highly cue-specific pattern of arousal. Our results suggest that copulatory movement displayed in non-human species is not a sexual cue that can elicit genital or subjective sexual arousal in humans.

RESUMEN

Due to social desirability bias, people tend to self-present themselves in the presence of others in a favorable light, which sometimes may lead to deviations from reality. This phenomenon is particularly pronounced when controversial or strictly norm-bounded matters are considered. Here, we tested how a presence of an attractive model-either male or female-influences people's declarations on their sociosexual orientation-the degree of their sexual permissiveness in terms of their past behavior, attitudes toward uncommitted sex, and desire for sexual intercourse with individuals they are not in a relationship with. The participants (N = 244, 52% men) answered questions about their sociosexuality in solitude, or out loud with an attractive model present. The results show that both men and women declare lowered levels of their desire, but not behavior or attitude, in the presence of both male and female attractive models. A follow-up study (N = 188, 51% men) showed that this effect was not due to the differing conditions of responding (out loud vs written down). The research points out to an area of human sexuality that is prone to being falsified in research and which serves as an important factor in self-presentation.

RESUMEN

We explored the unique roles that body and genital image play in behavior-specific orgasm consistency, beyond overall sexual self-esteem. US adults (N = 599; 64% women) completed questionnaires online. Hierarchical regression analyses predicted orgasm consistency during receptive oral sex and penile-vaginal intercourse (PVI) with additional clitoral stimulation (WAS) and with no additional clitoral stimulation (NAS) for the woman. Body image, genital image, and gender were entered in later steps to assess model improvement above sexual self-esteem. Models accounted for age, sexual and racial minority identities, and current relationship status. Results indicated that genital image improved all models and predicted higher orgasm consistency across all behaviors for men and women. For orgasm during receptive oral sex and PVI-NAS, sexual self-esteem was no longer significant once genital image was included. Genital image was a stronger predictor of women's versus men's orgasm during PVI-NAS; no significant gender differences were found for oral sex and PVI-WAS. Body image was not significant in any models, contrary to expectations, suggesting role overlap with sexual self-esteem. Genital image appears to play a unique role in sexual pleasure beyond overall sexual self-esteem and body image.

RESUMEN

INTRODUCTION AND HYPOTHESIS: This study was aimed at validating the Persian version of the International Female Coital Incontinence Questionnaire (IFCI-Q). METHODS: In the current study, 150 sexually active women with complaints of any kind of sexual dysfunction from January 2022 to July 2023, who were referred to urogynecology outpatient clinics, completed the IFCI-Q. Age ≥ 18 years and sexually active women were the inclusion criteria for the study. Quantitative calculations were made to determine the content validity ratio and content validity index. A test-retest procedure was utilized to determine the scale reliability. RESULTS: The mean (SD) age of participants was 35.66 (7.03) years. Among a total of 150 women, 21 (14.0%) had coital incontinence (CI), and this disorder happened during penetration in 11 cases (7.3%), orgasm in 9 (6.1%), or both conditions in one woman (0.7%). The intraclass correlation coefficient (95% confidence interval) was 0.79 (0.74, 0.84), and the Cronbach's α coefficient was 0.89. A positive association between the Female Sexual Function Index and the IFCI-Q was also demonstrated by the criteria validity (r = 0. 87 and p = 0.001). CONCLUSION: Regarding validity and reliability, the Persian version of the IFCI-Q can properly evaluate CI in women with sexual dysfunction or complaining of CI.

RESUMEN

BACKGROUND: The burden of early sexual engagement among youth is enormous. It directly raises the risk of sexually transmitted infections(STIs) and indirectly contributes to unintended pregnancy, unsafe abortion, premature childbirth, and psychosocial issues. The aim of this paper was to estimate the timing of sexual debut and examine the factors influencing the timing of first sexual intercourse following menarche among female youth aged between 15 and 24 in Uganda. METHOD: Self-reported data were extracted from the 2016 Uganda Demographic and Health Survey (UDHS), with a sub-sample of 7964 female youth from the individual woman file. Kaplan-Meier survival curves, decrement life-table analysis, and the discrete-time logit model were used to examine the timing of sexual debut and associated factors. RESULTS: 67.4% of the female youth had experienced first sexual initiation. Overall, the meantime to sexual debut was 4.4 years and the median time was 4.3 years, and all the female youth had experienced first sexual initiation by the end of the twelfth year following menarche. Significant factors found to influence the timing of sexual initiation include having higher education level (OR = 0.724: 95% CI = 0.59-0.89; p = 0.003), residing in the Northern region (OR = 0.877:95% CI = 0.79-0.97, p = 0.012), being employed (OR = 1.085: 95% CI = 1.01-1.16; p = 0.021), and being literate (OR = 1.155; 95% CI = 1.07-1.25; p < 0.001). CONCLUSIONS: These findings are expected to be central in the bid to delay first sexual intercourse. Also they shed light on some of the factors associated with the timing of sexual debut which may be addressed at community level for non-school going youth and in schools, as school based prevention sexual and reproductive health programs. The findings highlight the need for future studies to collect more data to explore further the linkage between time to first debut since menarche and, mass media, religion, type of residence, and wealth index.

RESUMEN

BACKGROUND: Existing estimates of adolescent sexual and reproductive health (ASRH) behaviors may be a gross undercount given the sensitivity of this behavior in Indian culture. The objective of this study was to estimate ASRH behaviors in Rajasthan, India using direct questions and the best friend approach that seeks to reduce social desirability bias. METHODS: We used population-based data of adolescents aged 15-19 in Rajasthan collected between September and December 2022. Data include whether the respondent and her closest female friend ever had a partner, ever had sex, ever used contraception, and were currently using contraception. We estimated respondent and best friend ASRH outcomes separately, overall and among unmarried adolescents for whom we anticipate social desirability bias is greatest. RESULTS: The best friend approach performed well, with method assumptions largely met even before adjustments. Respondent and best friend estimates were similar among all adolescents except for current contraceptive use, which was higher for friends (though not significantly so). However, we observed large differences in ASRH behaviors between unmarried respondents and friends, with a significantly higher percentage of friends who ever had a partner (4.3% respondents, 11.6% friends), and a slightly higher percentage who ever had sex (2.4%, 3.8%) and who were currently using contraception (17.0%, 19.7% among those in need of contraception). CONCLUSIONS: We observed potential benefits of using the best friend methodology in estimating premarital sexual activity, but further work is needed to refine social network-based measures of sensitive adolescent behaviors in larger study samples to better understand ASRH needs.

RESUMEN

BACKGROUND: Most Norwegian adolescents experience their first sexual intercourse during late adolescence. Use of contraception is important to avoid unwanted pregnancy, while condoms can also protect against sexually transmitted diseases. There are few studies on the use of contraception at first sexual intercourse, most with varying results, and some studies have only examined the use of contraception among girls. In our study, we aimed to determine the use of contraception at first sexual intercourse, and to investigate associations between use of contraceptives at first sexual intercourse, sociodemographic factors, and alcohol and other substance use. METHODS: The study was based on data from the national electronic youth survey Ungdata, conducted in 2020-2022 among 113 049 upper secondary pupils (15-19 years) in Norway, which was around 65% of pupils attending upper secondary school during the study period. Descriptive analysis was used to estimate the prevalence of contraceptive use at first sexual intercourse, and multivariate logistic regression analyses to investigate the association between contraceptive use, sociodemographic factors, and alcohol intoxication and substance use. RESULT: 32% of Norwegian adolescents did not use contraception at first sexual intercourse. More girls (57.4%) than boys (42.6%) reported use of contraception. Factors associated with non-use of contraception during first sexual intercourse among boys were having parents with no college /university education (OR = 1.22: CI 1.13-1.32), perceived poor family finances (OR = 1.22: CI 1.06-1.40), alcohol intoxication, and use of cannabis or other narcotic substances during the past 12 months. The same factors were associated with non-use of contraception among girls. Additionally, being older than 16 years (OR = 1.13: CI 1.06-1.19) was also associated with non-use of contraception at first sexual intercourse. CONCLUSION: Many adolescents did not use contraception at first sexual intercourse. Alcohol intoxication and use of cannabis or other narcotic substances were associated with a lower likelihood of using contraceptives. This highlights the importance of preventive efforts including earlier prevention education that focuses more on the consequences of not using contraception in order to prevent unwanted pregnancies and sexually transmitted infections.

RESUMEN

BACKGROUND: Hip pain due to femoroacetabular impingement (FAI) is thought to adversely impact sexual satisfaction because of exacerbation of symptoms with hip ROM. However, the effect of FAI on sexual satisfaction and improvement after surgery to treat FAI is largely absent from published studies, despite patients' apparent interest in it as registered by the frequent appearance of these topics on online anonymous discussion platforms. In addition, details regarding its impact on the decision to pursue surgery and the success of hip arthroscopy in alleviating FAI-related sexual dysfunction based on the specific role assumed during intercourse (penetrative versus receptive) remains unknown. QUESTIONS/PURPOSES: Given that sexual intercourse involves different amounts of hip ROM depending on whether patients assume the penetrative or receptive role, this study evaluated the effect of FAI and hip arthroscopy on sexual activity based on role. Compared with patients who participate in the penetrative role during sexual intercourse, do patients who participate in the receptive role (1) experience greater difficulty with sexual function because of FAI symptoms, (2) take longer to return to sexual intercourse after hip arthroscopy, and (3) experience greater improvements in reported sexual function after hip arthroscopy for FAI? METHODS: This was a retrospective cohort study of patients undergoing hip arthroscopy for FAI. Between January 2017 and December 2021, 293 patients were treated with hip arthroscopy for FAI and enrolled in our longitudinally maintained database. Among all patients treated surgically, 184 patients were determined to be potentially eligible for study inclusion based on a minimum follow-up of 6 months postoperatively. The 6-month timepoint was chosen based on published data suggesting that at this timepoint, nearly 100% of patients resumed sexual intercourse with minimal pain after hip arthroscopy. Of the potentially eligible patients, 33% (61 patients) could not be contacted by telephone to obtain verbal consent for participation and 9% (17 patients) declined participation, leaving 106 eligible patients. Electronic questionnaires were sent to all eligible patients and were returned by 58% (61 patients). Forty-two percent of eligible patients (45) did not respond to the questionnaire and were therefore excluded from the analysis. Two percent (2) completed most survey questions but did not specify their role during intercourse and were therefore excluded. The mean age of included patients was 34 ± 9 years, and 56% were women The mean follow-up time was 2 ± 1 years. In total, 63% of included patients reported participating in the receptive role during sexual intercourse (49% receptive only and 14% both receptive and penetrative). Hip symptoms during sexual intercourse preoperatively and postoperatively were evaluated using a questionnaire created by our team to answer our study questions, drawing from one of the only published studies on the matter and combining the questionnaire with sexual position-specific questions garnered from arthroplasty research. Patients who reported participating in the receptive role during intercourse (either exclusively or in addition to the penetrative role) were compared with those who participated exclusively in the penetrative role. There were no specific postoperative recommendations in terms of the timing of return to sexual intercourse, other than to resume when comfortable. RESULTS: Overall, 61% of patients (36 of 59) reported that hip pain somewhat or greatly interfered with sexual intercourse preoperatively. Patients who participated in receptive intercourse were more likely to experience preoperative hip pain that interfered with intercourse than patients who participated exclusively in penetrative intercourse (odds ratio 5 [95% confidence interval 2 to 15]; p < 0.001). Postoperatively, there was no difference in time until return to sexual activity between those in the penetrative group (median 6 weeks [range 2 to 14 weeks]) and those in the receptive group (median 6 weeks [range 4 to 14 weeks]; p = 0.28). Postoperatively, a greater number of patients participating in the penetrative role reported no or very little pain, compared with patients participating in the receptive role (67% [14 of 21] versus 49% [17 of 35]). However, with regard to preoperative to postoperative improvement, patients who participated in the receptive role had greater pain with positions involving more hip flexion and abduction and experienced a greater improvement than their penetrative counterparts in these positions postoperatively. Despite this improvement, however, 33% of patients (7 of 21) participating in the penetrative role and 51% of patients (18 of 35) participating in the receptive role continued to report either some or a great amount of pain at final follow-up. CONCLUSION: Hip pain secondary to FAI interferes with sexual relations, particularly for partners who participate in the receptive role. Postoperatively, both patients participating in receptive and penetrative intercourse resumed sexual intercourse at a median of 6 weeks. After hip arthroscopy, the greatest improvement in pain was seen in receptive partners during sexual positions that involved more hip flexion and abduction. Despite this improvement, most patients, regardless of sexual role assumed, reported some degree of residual pain. Patients planning to undergo arthroscopic surgery for FAI, particularly those who participate in receptive intercourse, should be appropriately counseled about reasonable postoperative expectations based on our findings. LEVEL OF EVIDENCE: Level III, therapeutic study.

RESUMEN

BACKGROUND: Access to an on-demand pericoital oral contraceptive pill - used to prevent pregnancy within a defined window around sexual intercourse - could offer women more reproductive agency. A contraceptive with this indication is not currently available in any market. This review aims to understand international user appeal for an on-demand pericoital oral contraceptive pill. METHODS: Systematic scoping review, comprising 30 peer-reviewed papers published between 2014-2023. RESULTS: Data from 30 papers reporting on research from 16 countries across five World Health Organisation regions suggests widespread user appeal for on-demand oral contraceptive pills that can be used peri- or post-coitally, especially among women who are younger, more educated or who have less frequent sex. Women of varying age, wealth, employment or relationship status, and with different prior experience of using modern contraceptives, were also interested. Women identified clear rationale for use and preference of these types of product: close alignment with women's sexual lives that comprised unplanned, spontaneous or occasional sex; perceived convenience and effectiveness; discreet use of pills to negotiate contextual circumstances that constrained their reproductive agency. Factors inhibiting use included knowledge barriers and attitudes of service providers, a lack of knowledge and misinformation among end-users, women's dislike of menstrual side effects and myths related to the effects of hormone content on future fertility. CONCLUSIONS: Introduction of an on-demand pericoital oral contraceptive pill could expand contraceptive choice for diverse women experiencing unmet need for modern contraception and constrained sexual and reproductive agency. Priorities for future research include: broadening the geographical scope of evidence to include SE Asia and the Pacific, and international rural and peri-urban settings; documenting the perspectives of adolescents and unmarried young people; identifying opportunities for innovation in the supply channels to enhance appropriate, affordable access to on-demand oral contraceptives; and unpacking how to bring new pericoital contraceptives to the market in a variety of international settings.


Access to an oral contraceptive pill that is used as needed to prevent pregnancy and taken within a defined window around sexual intercourse (i.e. an on-demand pericoital oral contraceptive pill) could offer women more reproductive agency. Though not currently available in any market, our analysis from this review of international literature reveals widespread appeal among women for using this type of contraceptive product. Clear rationale supporting use and preference included: (1) closer alignment with women's sexual lives that comprised desired but unplanned, spontaneous or occasional sex than other contraceptives; (2) perceived convenience and effectiveness, offering benefits over other modern contraceptives; and (3) women feeling able to overcome social values and beliefs that constrained their reproductive agency. There were also barriers to use of this type of product, including knowledge gaps and attitudes of service providers, a lack of knowledge and misinformation among end-users, women's dislike of the side effects, and myths and misconceptions about the impact of the hormone content in pills on future fertility. Introduction of an on-demand pericoital oral contraceptive pill could expand contraceptive choice for diverse women experiencing unmet need for modern contraception and constrained sexual and reproductive agency. Priorities for future research include: broadening the geographical scope of evidence to include SE Asia and the Pacific, and rural and peri-urban settings; documenting the perspectives of adolescents and unmarried young people; identifying opportunities for innovation in the supply channels to enhance appropriate, affordable access to this type of contraceptive; and unpacking how to bring this new contraceptive to the market in a variety of international settings.

RESUMEN

The CDC reports that 30% of high school students have engaged in sexual intercourse. Evidence suggests biological, personal, peer, societal, and family variables affect when a child will initiate sex. The school environment plays an important role in a child's development. Evidence suggests that greater attachment to the school community can modify sexual risk-taking activity in adolescents. Future of Families and Child Wellbeing Study (FFCWS) comprises a cohort of approximately 4,700 families of children born in the U.S. between 1998-2000, over-sampled for non-marital births in large U.S. cities. Adolescents (N = 3,444 of 4,663 eligible) completed the wave six teen survey at approximately age 15. School connectedness was self-reported with four items measuring inclusiveness, closeness, happiness, and safety felt by the adolescent in their school environment. Sexual intercourse and nonconsensual sex were self-reported by the adolescent. Hierarchical regression analyses were conducted examining sexual intercourse, nonconsensual sex, risk factors, and school connectedness. In this sample of adolescents (48% female, 49% Black, 25% Hispanic, ages 14-19), school connectedness appears to reduce boys' risk of nonconsensual sex (OR = 0.29, p < 0.01), and reduce girls' risk of engaging in sexual intercourse (OR = 0.55, p < 0.01). Findings suggest gender differences in the association between school connectedness and sexual practices in adolescents. School connectedness may confer protection for boys' risk of nonconsensual sex, and for girls' risk of engaging in sexual intercourse. Further exploration of the relationship between school connectedness may allow for recommendations into preventative measures for teenage sexual behaviors.

RESUMEN

INTRODUCTION: This study aimed to evaluate the impact of third-trimester post-coital bleeding (PCB) on pregnancy outcomes. METHODS: A retrospective cohort study was conducted at two tertiary medical centers, including all pregnant women between 24 and 34 weeks of gestation referred due to vaginal bleeding over an 11-year period. The study population includes all singleton deliveries; within this population, women were further classified into three groups: those admitted due to vaginal bleeding related to PCB, those admitted due to vaginal bleeding not related to PCB, and those who did not report vaginal bleeding. The primary outcome measure was delivery prior to 37 weeks of gestation, while secondary outcome measures included maternal and neonatal complications. Baseline characteristics of the two groups were compared. RESULTS: During the study period, there were a total of 51,698 deliveries. Among these, 230 cases involved bleeding between 24 and 34 weeks of gestation, 34 (14.8%) were identified as PCB, and 196 as bleeding unrelated to intercourse. In addition, 51,468 pregnancies without bleeding were analyzed as the general population for comparison. The incidence of preterm labor before 37 weeks of gestation was notably higher in both women with PCB (14.7%) and those with bleeding unrelated to coitus (20.9%) compared to the general population (5.6%); however, there was no statistically significant difference between the two bleeding groups (p = 0.403) while both were significantly different from the general population (p < 0.001). The odds ratio for preterm birth before 37 weeks of gestation after PCB was 3.29 (95% CI: 1.26-8.56, p = 0.0149). There were no significant differences between the PCB and bleeding unrelated to intercourse groups in terms of maternal and neonatal complications. CONCLUSION: This study found that third-trimester PCB is a risk factor for preterm delivery, with rates similar to other causes of third-trimester bleeding but significantly higher than the general population without bleeding. These findings challenge the assumption that PCB is benign.

RESUMEN

OBJECTIVES: The incidence of cervical cancer among patients with postcoital bleeding (PCB) was the primary objective of this study. Furthermore, the proportion of cervical intraepithelial neoplasia requiring treatment and the correlation between PCB and the presence of high-risk human papillomavirus (HPV) was determined. Lastly, the study aimed to identify risk factors among the referred women. METHODS: A retrospective cohort study was conducted at a university hospital in Denmark between January 1, 2017 and December 31, 2019. Women referred with PCB were identified with the ICD diagnosis codes "DN930 Postcoital and contact bleeding" and "DN930B Contact bleeding." Demographic and paraclinical data were extracted from the journals and the supportive systems: Patoweb and the Danish Microbiology Database. RESULTS: A total of 789 women were included in this study, with only 0.25% ( n = 2) diagnosed with cervical cancer and 2.5% ( n = 20) diagnosed with cervical intraepithelial neoplasia II-III and adenocarcinoma in situ. Human papillomavirus testing was only conducted in a minority of cases, and a low incidence of high-risk human papilloma virus was detected in the 22 cases, n = 5. CONCLUSIONS: A very low incidence of cervical cancer and high-grade cervical intraepithelial neoplasia reported among women referred with PCB. Prognostic factors as body mass index, smoking, and HPV vaccination status may predict the risk of cervical cancer. Selection criteria like primary testing for hrHPV and cytology as cotests before referral to colposcopy may reduce the number of unnecessary colposcopies.

RESUMEN

PURPOSE: Penile fracture (PF) affects 1,14 to 10,48 men in every 100.000 men in East Asia, and the primary aetiology is sexual intercourse, but the knowledge regarding the most dangerous sexual position is not well explained. This study compares three sexual positions: man on top position (MTP), woman on top position (WTP), and doggy style position (DSP), leading to PF potential. MATERIALS AND METHODS: A search of sexual position-related PF in Google Scholar, PubMed, Cochrane, and PMC Europe was performed. Criteria inclusion was the full text of relevant articles which describ the number of sexual positions. It was analyzed by odds ratio, random model effect, and the OR and 95%CI were calculated. RESULTS: 12 relevant papers involving 490 patients comprised 169 MTP, 120 WTP, 158 DSP, and 43 no intercourse cases. Meta-analysis of all sexual positions was a MTP P= 0,04, WTP P=0,49, and DSP P=0,0005. CONCLUSION: The man-dominant positions (MTP and DSP) were significantly potential for PF, which speculated that when a man is dominant and very excited, intercourse may become highly vigorous and impact trauma. This study found that man's dominant position consists of DSP and the MTP significantly lead to PF.
