RESUMO

Stimulating the clitoris activates the brain to instigate changes in the female genital tract, namely, the enhancement of vaginal blood flow that increases vaginal luminal pO2 , vaginal transudate (lubrication) facilitating painless penile penetration and partial neutralization of the basal luminal acidic pH, vaginal tenting, and ballooning delaying sperm transport and allowing semen de-coagulation and capacitation (sperm activation) factors to act until arousal ends (often by orgasm induction). All these genital changes taken together are of major importance in facilitating the possibility of reproductive success (and thus gene propagation) no matter how or when the clitoris is stimulated-they reveal its overlooked reproductive function. Of course, also commensurate with these changes, is its activation of sexual pleasure. The clitoris thus has both procreative (reproductive) and recreative (pleasure) functions of equal importance. Clitoridectomy creates not only sexual disability but also a reproductive disability. Clin. Anat. 32:136-145, 2019. © 2019 Wiley Periodicals, Inc.

RESUMO

BACKGROUND: Brazil has the largest population of individuals living with HIV/AIDS in Latin America, with a disproportional prevalence of infection among gays, bisexuals and other men who have sex with men (MSM). Of relevance to prevention and treatment efforts, Brazilian MSM from different regions may differ in behaviors and risk perception related to HIV. METHODS: We report on MSM living in 29 different cities: 26 Brazilian state capitals, the Federal District and two large cities in São Paulo state assessed in three web-based surveys (2016-2018) advertised on Grindr, Hornet and Facebook. Using logistic regression models, we assessed the association of risk behavior with HIV perceived risk as well as factors associated with high-risk behavior. RESULTS: A total of 16,667 MSM completed the survey. Overall, MSM from the North and Northeast were younger, more black/mixed-black, of lower income and lower education compared to MSM from the South, Southeast and Central-west. Though 17% had never tested for HIV (with higher percentages in the North and Northeast), condomless receptive anal sex (previous 6 months) and high-risk behavior as per HIV Incidence Risk scale for MSM were observed for 41 and 64%, respectively. Sexual behavior and HIV perceived risk had low variability by city and high-risk behavior was strongly associated with high HIV perceived risk. Younger age, being gay/homosexual, having a steady partner, binge drinking, report of sexually transmitted infection (STI) and ever testing for HIV were associated with increased odds of high-risk behavior. Awareness and willingness to use PrEP increased from 2016 to 2018 in most cities. CONCLUSIONS: Overall, MSM socio-demographic characteristics were heterogeneous among Brazilian cities, but similarities were noted among the cities from the same administrative region with a marked exception of the Federal District not following the patterns for the Central-West. Combination HIV prevention is most needed among young men who self-identify as gay/homosexual, report binge drinking or prior STI.

RESUMO

Adolescence is the transitional bridge between childhood and adulthood; it encompasses developmental milestones that are unique to this age group. Healthy cognitive, physical, sexual, and psychosocial development is both a right and a responsibility that must be guaranteed for all adolescents to successfully enter adulthood. There is consensus among national and international organizations that the unique needs of adolescents must be addressed and promoted to ensure the health of all adolescents. This policy statement outlines the special health challenges that adolescents face on their journey and transition to adulthood and provides recommendations for those who care for adolescents, their families, and the communities in which they live.

RESUMO

Despite significant declines over the past 2 decades, the United States continues to experience birth rates among teenagers that are significantly higher than other high-income nations. Use of emergency contraception (EC) within 120 hours after unprotected or underprotected intercourse can reduce the risk of pregnancy. Emergency contraceptive methods include oral medications labeled and dedicated for use as EC by the US Food and Drug Administration (ulipristal and levonorgestrel), the "off-label" use of combined oral contraceptives, and insertion of a copper intrauterine device. Indications for the use of EC include intercourse without use of contraception; condom breakage or slippage; missed or late doses of contraceptives, including the oral contraceptive pill, contraceptive patch, contraceptive ring, and injectable contraception; vomiting after use of oral contraceptives; and sexual assault. Our aim in this updated policy statement is to (1) educate pediatricians and other physicians on available emergency contraceptive methods; (2) provide current data on the safety, efficacy, and use of EC in teenagers; and (3) encourage routine counseling and advance EC prescription as 1 public health strategy to reduce teenaged pregnancy.

RESUMO

This article will explore the impact of ageing on sexual function in older women and will reflect on the social influences on women's sexual ageing, identify the effects of ageing on sexual activity, particularly on genital skin, and consider the concerns from the perspective of older women. The article will then focus on vulval skin conditions and the functional aspects of living with these conditions. Finally, the article provides a starting point for nurses to consider their own knowledge, skills and attitudes through a series of reflective questions and recommendations for those working with older women to aid the identification of issues relating to older women's sexual health and vulval skin conditions, leading to further discussions to promote genital health.

RESUMO

In both correlational and experimental settings, studies on women's vocal preferences have reported negative relationships between perceived attractiveness and men's vocal pitch, emphasizing the idea of an adaptive preference. However, such consensus on vocal attractiveness has been mostly conducted with native English speakers, but a few evidence suggest that it may be culture-dependent. Moreover, other overlooked acoustic components of vocal quality, such as intonation, perceived breathiness and roughness, may influence vocal attractiveness. In this context, the present study aims to contribute to the literature by investigating vocal attractiveness in an underrepresented language (i.e., French) as well as shedding light on its relationship with understudied acoustic components of vocal quality. More specifically, we investigated the relationships between attractiveness ratings as assessed by female raters and male voice pitch, its variation, the formants' dispersion and position, and the harmonics-to-noise and jitter ratios. Results show that women were significantly more attracted to lower vocal pitch and higher intonation patterns. However, they did not show any directional preferences for all the other acoustic features. We discuss our results in light of the adaptive functions of vocal preferences in a mate choice context.

RESUMO

The tip of the tail in female Cerastes vipera, a small viperid snake, is black and conspicuous, whereas that of the male is not. We tested the hypothesis, albeit indirectly, that this sexual dimorphic chromatisation is related to caudal luring, a feeding mimicry hunting strategy. C. vipera can hunt nocturnally-active lizards only via sit-and-wait ambush and, consequently, we predicted that females would use caudal luring more often than males and that the proportion of nocturnal prey items in the diet of females would be higher than in males. Our hypothesis was supported as: 1) only females demonstrated caudal luring towards nocturnally-active lizards and more than 85% did so, whereas none of the males demonstrated such behavior; and 2) females consumed a significantly higher proportion (15/40 vs 4/27) of nocturnally-active lizards than did males. We concluded that sexual dichromatisation in C. vipera is associated with hunting strategy that results in different hunting behavior and different dietary intake between sexes. These novel findings: 1) provide a functional explanation for the black tail of female C. vipera; and 2) suggest different evolutionary driving forces between sexes and, consequently, different ecological impacts of male and female C. vipera on lizard populations.

RESUMO

BACKGROUND AND AIMS: Cybersex is increasingly associated with concerns about compulsive use. The aim of this study was to assess the roles of motives and sexual desire in the compulsive use of cybersex. METHODS: The sample consisted of 306 cybersex users (150 men and 156 women). The participants were assessed using the Compulsive Internet Use Scale (CIUS) adapted for cybersex, the Cybersex Motives Questionnaire (enhancement, coping, and social motives), and the Sexual Desire Inventory-2 (dyadic and solitary sexual desire). RESULTS: For both genders, coping motive was associated with CIUS score. For women, an additional association with social motives was found whereas an association with sexual desire was found for men. CONCLUSION: The study showed gender differences in the contributors to sex-related CIUS scores.

RESUMO

BACKGROUND AND AIMS: People from the community seeking treatment in frameworks such as Sexaholics Anonymous (SA) and sex offenders are preoccupied with sex, sexual fantasies, and behaviors. The rates of compulsive sexual behavior disorder (CSBD), however, are reported to be substantially lower among sex offenders than SAs. In this study, we examined differences between SAs and sex offenders in CSBD and in processes that might be at the core of CSBD - maladaptive schemas about the self and others, impulsivity, and sensation seeking. METHODS: The study comprised 103 sex offenders, 68 SAs, and 81 violence offenders who served as controls aged 18-74 years, who completed self-report measures regarding CSBD, maladaptive schemas, impulsivity, and sensation seeking. RESULTS: SAs were higher on CSBD, maladaptive schemas, impulsivity, and sensation seeking than sex offenders. Sex offenders were higher on CSBD and impulsivity than violence offenders. Among all groups, maladaptive schemas were linked with higher CSBD. CONCLUSIONS: High rates of CSBD among SAs might partially be accounted by differences in maladaptive schemas. We discuss the implication of the study to the understanding of CSBD, sexual offences, and therapy for CSBD and sexual offending.

RESUMO

BACKGROUND AND AIMS: Gambling disorder (GD) and compulsive sexual behavior (CSB) may commonly co-occur. Yet, the psychiatric correlates of these co-occurring disorders are an untapped area of empirical scrutiny, limiting our understanding of appropriate treatment modalities for this dual-diagnosed population. This study examined the demographic and clinical correlates of CSB in a sample of treatment-seeking individuals with GD (N = 368) in São Paulo, Brazil. METHODS: Psychiatrists and psychologists conducted semi-structured clinical interviews to identify rates of CSB and other comorbid psychiatric disorders. The Shorter PROMIS Questionnaire was administered to assess additional addictive behaviors. The TCI and BIS-11 were used to assess facets of personality. Demographic and gambling variables were also assessed. RESULTS: Of the total sample, 24 (6.5%) met diagnostic criteria for comorbid CSB (GD + CSB). Compared to those without compulsive sexual behaviors (GD - CSB), individuals with GD + CSB were more likely to be younger and male. No differences in gambling involvement emerged. Individuals with GD + CSB tended to have higher rates of psychiatric disorders (depression, post-traumatic stress disorder, and bulimia nervosa) and engage in more addictive behaviors (problematic alcohol use, drug use, and exercise) compared to GD - CSB. Those with GD + CSB evidenced less self-directedness, cooperativeness, self-transcendence, and greater motor impulsivity. Logistic regression showed that the predictors of GD + CSB, which remained in the final model, were being male, a diagnosis of bulimia, greater gambling severity, and less self-transcendence. DISCUSSION AND CONCLUSION: Given those with GD + CSB evidence greater psychopathology, greater attention should be allocated to this often under studied comorbid condition to ensure adequate treatment opportunities.

RESUMO

The first semester of college is marked by increases in both heavy episodic drinking and sexual activity, including hookups. Because drinking and casual sex are highly related and college students believe that drinking settings facilitate hookups, students may drink as a way of facilitating uncommitted sexual partnerships. In 2 samples of college freshman women, we considered whether sociosexuality, a personality trait reflecting interest in casual, uncommitted sexual partnerships, prospectively predicted frequency of drinking. In Study 1 (N = 142), sociosexuality, assessed early in the first semester of college, positively predicted frequency of drinking occasions at the end of the semester after controlling for initial drinking frequency. In Study 2 (N = 654), sociosexuality again predicted frequency of drinking occasions after controlling for initial drinking frequency. Expected hookups with alcohol, but not expected hookups without alcohol, also predicted frequency of heavy episodic drinking occasions. Findings suggest that drinking frequency among college freshman women may reflect, at least in part, their interest in uncommitted sexual encounters. Because freshman women face a disproportionate risk of sexual assault relative to older students and drinking and sexual activity serve as significant risk factors, these findings have particular relevance for sexual assault prevention efforts.

RESUMO

Following previous studies, chronotype was related to sexual attitudes and behavior. Evening people tend to be more promiscuous and follow short-term mating strategies and extra-pair matings (EPM), which might lead to a higher reproductive success. In this study, one aim was to assess reproductive success directly by asking for children, and, second, to obtain a higher sample size for the analysis of sexual behavior and chronotype than in previous studies. N = 1,843 heterosexual persons (551 men, 1,288 women, 4 without data) responded to our online survey. Five hundred fifty-nine persons were single and 1,281 in a relationship; 203 reported having children (1.9 ± 0.81). Age was positively related and age at first intercourse was negatively related to the number of children. People being later chronotypes had fewer children, and shorter sleep duration was linked with more children. Extroversion was correlated with number of children, as was the long-term relationship orientation. Sociosexual orientation and EPM were unrelated to number of children. Age at first intercourse was earlier in evening people, and unrestricted sociosexuality was higher in late chronotypes. Morning orientation correlated with long-term relationship orientation and eveningness with short-term relationship orientation. Number of sexual partners was lower in morning people. Men were more evening oriented, later chronotypes, and slept shorter. There were no differences in sociosexual behavior, but men were less restricted in attitude and desire. Men scored higher on short-term relationship orientation and women higher on long-term relationship orientation. This study confirmed previous results about chronotype and sexual behavior but provided the first evidence that morningness was related to higher reproductive success.

RESUMO

Sexual reproduction plays a fundamental role in diatom life cycles. It contributes to increasing genetic diversity through meiotic recombination and also represents the phase where large-sized cells are produced to counteract the cell size reduction process that characterizes these microalgae. With the aim to identify genes linked to the sexual phase of the centric planktonic diatom Skeletonema marinoi, we carried out an RNA-seq experiment comparing the expression level of transcripts in sexualized cells with that of large cells not competent for sex. A set of genes involved in meiosis were found upregulated. Despite the fact that flagellate gametes were observed in the sample, we did not detect the expression of genes involved in the synthesis of flagella that were upregulated during sexual reproduction in another centric diatom. A comparison with the set of genes changing during the first phases of sexual reproduction of the pennate diatom Pseudo-nitzschia multistriata revealed the existence of commonalities, including the strong upregulation of genes with an unknown function that we named Sex Induced Genes (SIG). Our results further broadened the panel of genes that can be used as a marker for sexual reproduction of diatoms, crucial for the interpretation of metatranscriptomic datasets.

RESUMO

BACKGROUND: Infidelity in romantic relationships is a common, but severe issue often causing breakup and severe psychological impairment. Higher levels of testosterone are related to mating-behavior, sexual desire, and infidelity in men with sexual dysfunctions. Previous studies, have insufficiently addressed the potential role of testosterone in infidelity in healthy men. METHODS: A sample of 224 middle-aged self-reporting healthy men being currently in a relationship completed questionnaires on relationship characteristics, infidelity, and provided overnight-fasting saliva samples for testosterone quantification. RESULTS: In the sample, 37.5% men answered having been unfaithful in the current relationship, while 29% were identified as fulfilling criteria for a sexual dysfunction. Adjusting for covariates, a significant positive association for the frequency of unfaithful behavior and testosterone levels emerged. Subsample analysis indicates a positive association between testosterone and infidelity only to be present in men without sexual dysfunction. CONCLUSION: Unfaithful behavior in males is associated with higher testosterone levels.

RESUMO

OBJECTIVE: This study aims to verify the association between risk factors for the onset of SUI and transobturator suburethral sling surgical treatment outcomes. PATIENTS AND METHODS: A retrospective study was conducted with 57 patients operated by the Pelvic Floor Surgery Service. Demographic data were compiled from the sample, the body mass index (BMI) was calculated, and the patients were divided according to the response to the surgical treatment. RESULTS: A total of 77.2% of the sample was cured or improved after surgical treatment. Out of the total sample, 75.4% of the women were postmenopausal, and 73.7% denied current or past smoking. The median age was 61 years, the median number of births was 4.0, the median BMI was 28.6 kg/m2, and 50.9% of the sample was classified as pre-obese. BMI, menopausal status, age, smoking, and sexual activity were not factors associated with the surgical outcome. However, parity equal to or greater than 5 was associated with worse postoperative results (p = 0.004). CONCLUSIONS: among risk factors associated with the emergence of SUI, only parity greater than 4 showed a negative impact on transobturator sling surgery outcomes.

RESUMO

The prevalence of, and related factors to, stress urinary incontinence (SUI) among perimenopausal Chinese women and its impact on daily life among those women with sexual desire problem in Hubei province were investigated. In this study, 1519 perimenopausal women aged 40 to 65 years were selected from three urban communities in the Wuhan area, and two impoverished, mountainous communities in Hubei province, and followed from April to October 2014. Detailed information about demographic characteristics, menstruation, pregnancy, sexual life and chronic diseases was collected. A cross-sectional survey was carried out following information collection by Chi-square test and multiple logistic regression analysis. Univariate and multivariate logistic regression analysis demonstrated that the potential factors associated with developing SUI were old age (OR=3.4, 95% CI: 1.92-6.04), vaginal delivery (OR=0.623, 95% CI: 0.45-0.87), low income (OR=0.063, 95% CI: 0.40-0.92), atrophic vaginitis (OR=1.4, 95% CI: 1.03-1.80), pelvic organ prolapse (OR=2.81, 95% CI: 1.36-5.80), chronic pelvic pain (OR=2.17, 95% CI: 1.90-4.03), constipation (OR=1.44, 95% CI: 1.07-1.93) and incontinence of feces (OR=3.32, 95% CI: 2.03-5.43). Moreover, the ratio of SUI (33.2%) was higher than the ratio of urgency urinary incontinence (24.1%) or the ratio of mixed urinary incontinence (17.4%), and SUI had a greater impact on daily life among women with decreased sexual desire. In conclusion, SUI is a common disorder affecting over one third of the women surveyed, and has a severe impact on the daily life of perimenopausal women with declined sexual desire. Age, mode of delivery, and monthly income are major risk factors involved in the development of SUI.

RESUMO

BACKGROUND: Unprotected anal intercourse (UAI) has previously been associated with human immunodeficiency virus (HIV) infection. Male students who have sex with men (SMSM) are at increased exposure to experience UAI. The aim of this study was to investigate the status of UAI and related factors among SMSM in three northern regions of China. METHODS: From November 2018 to January 2019, SMSM, 18 years or older, studying or living in Beijing, Tianjin, or Shijiazhuang, who had anal sex in the past 6 months were recruited by community-based organizations to participate in an unmatched, case-control study. Detailed demographic and behavioral information were collected via self-administrated electronic questionnaires and factors related to UAI were assessed using uni- and multivariate logistic regression analyses. RESULTS: Among the 511 SMSM included in the study, 210 (41.1%) reported UAI in the past 6 months. SMSM who had sexual partners at least 10 years older than themselves (odds ratio [OR] = 2.277, 95% confidence interval [CI]: 1.380-3.756), used vacant capsules before sexual activity (OR = 3.858, 95% CI: 1.472-10.106), had a self-perceived moderate-HIV risk (OR = 2.128, 95% CI: 1.403-3.227), and unprotected, first anal intercourse (OR = 2.236, 95% CI: 1.506-3.320) had increased odds of UAI. CONCLUSIONS: Factors associated with increased odds of engaging in UAI in the past 6 months among SMSM included having older sexual partners, using vacant capsules, having a self-perceived moderate risk of HIV, and unprotected, first anal intercourse. Continuing education on risk reduction, including improving condom decision making in age-discordant relationships could help address the sexual risk behaviors among SMSM.

RESUMO

Several endocrinological and physical activities orchestrate men's sexual activities. To determine whether body composition calculated by computed tomography measurements is useful for estimating sexual function, we evaluated sexual function of localised prostate cancer patients using the Sexual Health Inventory for Men score, an original questionnaire, and computed tomography and magnetic resonance imaging. The imaging was performed to determine body composition, particularly the psoas muscle. Univariate and multivariate analyses were performed to identify factors affecting sexual activity. The multivariate analysis showed that the volume of the psoas muscle was significantly correlated with sexual activity (odds ratio [95% confidence interval]) (2.507 [1.029-6.109], p = 0.043) and erectile dysfunction (0.261 [0.098-0.692], p = 0.006). We concluded that the psoas muscle is an important predictor of sexual activity and erectile function.

RESUMO

Background: Gastric cancer (GC) is one of the leading causes of cancer-related death in Vietnam. Research on health-related quality of life of Vietnamese gastric cancer patients is still in its infancy. Aim: To assess the health-related quality of life (HRQOL) of GC patients using the 15D instrument. Materials and Method: 182 Vietnamese gastric cancer patients were selected to be interviewed and their HRQOL was assessed using the generic 15D questionnaire. Tables regarding history, disease characteristics, and HRQOL of participants were formulated according to genders using STATA 12.0. Results: The average age of the participants was 60.8 ± 11.6. The average time from diagnosis to the date of interview was 14.8 ± 8.4 months. The health-related quality of life (HRQOL) index score of gastric cancer patients using the 15D instrument was 0.92 ± 0.08, in which the "sexual activity" dimension had the lowest score of 0.66. Also, our study found several factors affecting HRQOL, including age, occupation, education, disease stage, treatment, and time from the date of diagnosis. Conclusion: The 15D instrument was a suitable tool to assess Vietnamese gastric cancer patients' quality of life. Findings from the study suggest the importance of frequently measuring personal functioning and performance of GC patients as parts of QOL assessment during clinical examination. It also implies the needs for more focused policies on raising the overall quality of life of patients such as encouragement of periodical HQROL assessment and acknowledging HRQOL as a treatment/intervention goal besides the 5-year survival rate.

RESUMO

Despite common use of antidepressants to treat postpartum depression, little is known about the impact of antidepressant use on postpartum brain activity. Additionally, although oxytocin has been investigated as a potential treatment for postpartum depression, the interaction between antidepressants and exogenous oxytocin on brain activity is unknown. We explored postpartum depressed women's neural activation in areas identified as important to emotion and reward processing and potentially, antidepressant response: the amygdala, nucleus accumbens and ventral tegmental area. We conducted a secondary analysis of a functional imaging study of response to sexual, crying infant and smiling infant images in 23 postpartum depressed women with infants under six months (11 women taking antidepressants, 12 unmedicated). Participants were randomized to receive a single dose of oxytocin or placebo nasal spray. There was significantly higher amygdala activation to sexual stimuli than either neutral or infant-related stimuli among women taking antidepressants or receiving oxytocin nasal spray. Among unmedicated women receiving placebo, amygdala activation was similar across stimuli types. There were no significant effects of antidepressants nor oxytocin nasal spray on reward area processing (i.e., in the nucleus accumbens or ventral tegmental area). Among postpartum women who remain depressed, there may be significant interactions between the effects of antidepressant use and exogenous oxytocin on neural activity associated with processing emotional information. Observed effect sizes were moderate to large, strongly suggesting the need for further replication with a larger sample.
