Seasonal variation and synchronization of sexual behaviors in free-ranging male Tibetan macaques (Macaca thibetana) at Huangshan, China

Although seasonal breeding has been documented in many non-human primates, it is not clear whether sexual behaviors show seasonal variation among male individuals. To test this hypothesis, the focal animal sampling method and continuous recording were used to investigate seasonal variation and synchronization of sexual behaviors in five male Tibetan macaques （Macaca thibetana） at Mt. Huangshan from Oct 2005 to Sept 2006. Both copulatory and sexually motivated behaviors （i.e., sexual chase, grimace, and sexual-inspection）, which were significantly higher in the mating season than non-mating season. Furthermore, seasonal variations of sexual behaviors, including copulatory and sexually motivated behaviors, were synchronized among males. The results shed light on sexual competition and tactics for reproductive success of male M. thibetana and other non-human primates with seasonal breeding.

Effects of Intraperitoneal Injection of Polychlorinated Biphenyls During Pregnancy on Sexual Behavior of F1 Rats

50 time-mated pregnant rats were divided into five groups and injected daily from gestational days 7 to 18 with either 2,2＇ ,4,4＇-tetrachlorobiphenyl （PCB 47） at the dosage of 1.00 or 20.00 mg/kg body weight; or 3,3＇ ,4,4＇-tetrachlorobiphenyl （PCB 77） at the dosage of 0.25 or 1.00 mg/kg body weight; or sesame oil （control） to investigate the effects of fetal and lactational PCB exposure on reproductive behavior in male and female laboratory rats. Offspring were then tested for male sexual behavior： mount frequency, MF; mount latency, ML; intromission frequency, IF; intromission latency, IL; ejaculation latency, EL; post ejaculatory interval, PEI; hit rate and female sexual behavior; approach latency, AL; mount return latency, MRL; intromission return latency, IRL; post ejaculatory refractory period, PER; lordosis quotient, LQ. Measures were made at the age of postnatal days 70 to 91, and 97 to 101, respectively. The results showed that exposure to both PCB 77 and PCB 47 significandy reduced the LQ （84.4% for control, 76.0%, 67.8% for PCB 47 groups and 64.4%, 53.3% for PCB 77 groups; P〈0.05） in the female offspring. There were no significant effects on AL, MR, IRL, PER （P〉0.05） of the female offspring, or on MF, ML, IF, IL, EL, PEI and hit rate （P〉0.05） of the male offspring.

High-risk Sexual Behavior among HIV-positive Former Commercial Blood Donors in Rural Eastern and Central China

Objective： To investigate high-risk sexual behavior among HIV-positive former commercial blood donors in rural central and eastern China. Methods： From December 2003 to May 2004, a crosssectional study was conducted to investigate demographic characteristics, sexual behaviors, condom use, and knownHIV status among HIV-positive commercial blood donors.A total of 796 subjects were recruited for the study. Results： Of the 796 study subjects, 53.0% （258/487） did not use condoms, 10.9% （53/487） inconsistently usedcondoms, and 36.1% （176/487） consistently used condoms with a steady sex partner in the past threemonths. Age （OR, 0.57; 95% CI： 0.39, 0.82）, years of education （OR, 1.90; 95% Ch 1.27, 2.84） and known HIVstatus （OR, 1.66; 95% CI： 1.12, 2.45） were independently and positively associated with condom use with a steady sex partner. Of those subjects without a steady sexual partner in the past year, 63.6% （14/22） did not use condoms, 9.1% （2/22） inconsistently used condoms, and 27.3% （6/22） consistently used condoms. Conclusion： HIV counseling and education should be focused on HIV-positive blood donors to prevent a secondary spread of HIV through unsafe sexual practices.

Seminal characteristics and sexual behavior in men of different age groups： is there an aging effect？

Aim： To assess the seminal characteristics as well as the sexual behavior of men of various age groups to establish the presence of an aging effect on those characteristics. Methods： Semen samples were collected from men （n = 792） undergoing in vitro fertilization or intrauterine insemination in cases of female factor infertility only. Samples were collected using a seminal collection device at intercourse and evaluated manually according to World Health Organization （WHO） standards. Men were divided into four groups according to their ages： （i） 20-30, （ii） 31-40, （iii） 41-50 and （iv） 51-60 years, and their seminal characteristics and responses to a sexual behavior questionnaire were compared. Results： The data showed statistically significant differences in the seminal characteristics tested, most notably in the sperm concentration, motility, grade of motility, hypo-osmotic swelling and normal sperm morphology. Furthermore, the decline in normal sperm morphology with age was more pronounced when using strict criteria rather than WHO standards. There were also differences in total sperm count, total motile sperm and total functional sperm fraction （assessed by both WHO and strict criteria）. Significant differences were also observed in the sexual behavior patterns in older men in terms of the number of years they have been trying to conceive, sexual frequency and sexual satisfaction. Conclusion： The data clearly illustrate an aging effect on semen characteristics and sexual behavior in men as they age. It is suggested that the aging effect be taken into consideration when proposing normal standard values for semen characteristics in routine semen analysis as outlined by WHO standards.

Improved sexual behavior in male rats treated with a Chinese herbal extract： hormonal and neuronal implications

Aim： To investigate the influence of an extract obtained from five Chinese medicinal plants on sexual behavior of adult male rats. Methods： The extract was administered at doses of 30, 60 and 120 mg/kg by oral gavage, acutely （one time, 45 min before mating test） or subchronically （daily for 10 days） in sexually potent and sexually sluggish/impotent rats. Sexual behavior, serum levels of luteinizing hormone （LH） and testosterone （T） were evaluated in treated rats and compared with controls receiving vehicle. The effect of the extract on central dopaminergic neurotransmission was assessed in the nucleus accumbens using a microdialysis technique. Results： In sexually potent rats, both acute and subchronic treatment with the extract dosed at 30 and 60 mg/kg reduced mount latency and intromission latency. In sluggish/impotent rats, the acutely administered extract at the dose of 60 mg/kg shortened ejaculation latency, whereas subchronically administered at the doses of 30 and 60 mg/kg, reduced mount, intromission and ejaculation latencies, increasing also the percentage of mounting and ejaculating rats. The extract dosed at 60 mg/kg significantly increased LH and T following acute and subchronic administration and increased 3,4-dihydroxyphenylacetic acid levels in the nucleus accumbens, 30 min after the acute administration. Conclusion： The improvement in both appetitive and consummatory components of sexual behavior observed in male rats treated with the extract could be ascribed to increased serum T level in parallel with the activation of the central dopaminergic system.

Teenagers’Sexual Behavior in Sweden, Europe

Objective To investigate the development of sexuality from early to late adolescence, and to compare girls and boys of different ages Methods A cross sectional survey in all schools was performed covering all pupils between 13 and 18 years of age that were in school when the survey was conducted. A validated instrument, Q90, created for use in teenagers was distributed in the class- rooms to 3 216 teenagers. Q90 covers 30 questions about body development and sexual behavior. Non-response was insignificant （n=19; 0.6%）. Results Pubertal development was considered “early” or “late” by about 50% of both boys and girls. Eighty percent of the 13 to 15 years old boys and girls had had a romance and 30% had experience of sexual cuddling （petting）, while significantly more girls than boys had sexual intercourse （18% vs 13%; odds ratio 1.5, 95% CI 1.1-1.9）. The difference between girls and boys remained in those being 16-18 years old, where 63% of the girls and 53% of the boys （odds ratio 1.5, 95% CIJ.2-1.9） admitted having intercourse. Mean age at first intercourse was 14.9 and 15 years, respectively. At 16-18 years of age, 23% of the sexually active girls, as compared with 25% of the boys estimated that they had had 6 or more sexual partners. About 30% of the adolescents, irrespective of age and gender, did not use contraceptives at their first and latest intercourse. Eight percent of the older girls had been pregnant, and they had an increased history of sexually transmitted infections, as compared with the boys （6.2% vs 2.7%, odds ratio 2.4, 95% CI 1.2-5.0）. Conclusion Exploring sexuality and experimentation is a normal behavior in adolescence. The results of this study, however, indicate that there are substantial groups of teenagers who practice sexual risk-taking. In addition to general sexual education, programs should also be directed to define sexual risks and its consequences.

Effect of Luteinizing Hormone-Releasing Hormone Analogue on the Sexual Behavior of Sacalia quadriocellata

Luteinizing hormone-releasing hormone(LHRH) is known to influence sexual behavior in many vertebrate taxa, but there have been no systematic studies on the role of LHRH in sexual behavior of turtles. We tested the hypotheses that exogenous LHRH analogues would induce sexual behavior of male Four-eyed turtle, Sacalia quadriocellata. We examined this by challenging males with intramuscular injections of mammalian luteinizing hormone-releasing hormone analogue(LHRH-A), human chorionic gonadotropin(HCG), or a combination of the two, and subsequently exposing them to sexually receptive females for behavioral observation. Our data show that the injection of only HCG could not, while that of only LHRH-A could, facilitate sexual behavior along with testicular recrudescence and spermatogenesis in S. quadriocellata. The injection of both LHRH-A and HCG would induce more drastic sexual behavior of the animals than that of LHRH-A alone, indicating HCG enhances the effects of LHRH-A induced sexual behavior. However, different pharmacological dosages of LHRH-A(0.5 μg, 1 μg, 2 μg per 100 g bodyweight) did not correspond to different activity levels. Though the mechanism of LHRH effect was not determined, this study may support that the sexual behavior of S. quadriocellata which occurs at the beginning of the injection despite regression of the gonads. This is the first report on the exogenous LHRH-A induced sexual behavior for this species.

Effects of Bisphenol A on Testosterone Levels and Sexual Behaviors of Male Mice

Objective: To evaluate the effects of bisphenol A (BPA) on testosterone levels and sexual behaviors of male mice. Methods: Forty 12-week-old male mice, 22 - 25 g, were randomly allocated into four equal groups (n = 10 per group): the control group and three BPA exposure groups including low concentration group (10 mg/kg), middle concentration group (50 mg/kg) and high concentration group (100 mg/kg). Each mouse received BPA intraperitoneally injected for 21 consecutive days. Sexual behaviors and testosterone levels in serum and interstitial tissue of testis were measured after the last administration of BPA. Furthermore, we also observed the weights of sexual organs of each group, including testis, epididymis and seminal vesicle. Results: The mount latency in the high concentration group, the intromission latency in the middle and the high concentration group were 11.64 ± 2.67 min, 20.28 ± 3.40 min and 20.13 ± 2.06 min respectively. All of them were longer than the control group (all P < 0.05). The mount frequency, intromission frequency and copulatory efficacy in the high concentration group were 0.52 ± 0.15 numbers/min, 0.37 ± 0.12 numbers/min and 0.40 ± 0.03, which were all statistically lower than the control group (all P < 0.05). The average testis weights in the low, middle and high concentration group were 0.198 ± 0.032 g, 0.203 ± 0.037g and 0.183 ± 0.032 g, and the relative testis weight in the high concentration group was 0.637 ± 0.106. All of these data were lower than the control group (P < 0.05, P < 0.05, P < 0.01 and P < 0.05, respectively). The epididymis weight and the relative epididymis weight, the weight of seminal vesicle and the relative weight of seminal vesicle were 0.069 ± 0.010 g, 0.242 ± 0.040, 0.219 ± 0.042 g and 0.760 ± 0.143, and all of them were lower than the control group (all P < 0.05). The serum testosterone levels in the high concentration group, the intratesticular testosterone levels in the middle and the high concentration group were 7.88 ± 1.62 ng/ml, 75.5 ± 7.18 ng/g and 73.00 ± 9.57 ng/g, which were all lower than the control group (all P < 0.05). Conclusions: BPA can decline the testosterone levels in mice and inhibit their sexual behaviors.

Impact of Cellphone Radiation on Sexual Behavior and Serum Concentration of Testosterone and LH in Male Mice

Background: Cellphone radiation (CR) has been reported to be related to higher risk of many health problems, but if CR can impair sexual behavior and testosterone synthesis has seldom been studied. Objective: To evaluate the effects of CR on testosterone and luteinizing hormone (LH) levels and sexual behaviors of male mice. Methods: Forty 3-month-old male mice, 22 - 25 g, were randomly allocated into four equal groups (n = 10 per group): the control group and three CR exposure groups including 8-hour group, 16-hour group and 24-hour group. Each mouse received different dose of CR exposure for 30 consecutive days. Sexual behaviors and testosterone and LH levels in serum were measured at the end of experiment. Furthermore, we also observed the weights of reproductive organs of each group, including testis, epididymis and seminal vesicle. Results: The mount latency and intromission latency in 24-hour group were significant higher than the control (both P < 0.01), while no obvious changes were seen in 8-hour group and 16-hour group (all P > 0.05). No difference in ejaculation latency existed among each group after the experiment (all P > 0.05). The frequency of mount and intromission in 24-hour group was statistically significantly lower than that of the control group (P < 0.05 and P < 0.01, respectively). No obvious change in the frequency of mount and intromission of the 8-hour group and 16-hour group was seen (all P > 0.05). Only the copulatory efficacy in the 24-hour group was statistically lower than the control group (P < 0.05). The serum levels of testosterone and LH in the 24-hour group were obviously higher than the control group (testosterone level: P < 0.05;LH level: P < 0.01). No significant differences were seen among the other two experimental groups and the control group (all P > 0.05). After the exposure of CR, the changes in the weights of sexual organs in the 24-hour group were significant compared with the control (testis weights, relative testis weight, epididymis weight, the weight of seminal vesicle, and the relative weight of seminal vesicle, all P < 0.01;the relative epididymis weight, P < 0.05). Conclusions: High dose exposure of CR can decline the testosterone and LH levels in mice and inhibit their sexual behaviors.

Correlation Study on Body Size,Sexual Behavior and Semen Quality of Dezhou Donkey

[ Objective] The study was to explore whether the body size, sexual behavior of male donkey had certain correlation with reproductive traits. [ Method] The data of body weight, body size and sexual behavior of male donkey during production were collected, combining with the semen quality data of ejaculation volume, density, motility and frozen-thawed semen motility were conducted the statistical analysis. [ Results] （ 1 ） Single ejaculation volume had a positive correlation with body height （r = 0. 423, P = 0. 044） and penis circumference （r = 0. 495, P = 0. 043 ） , and total number of sperm per ejaculate had a positiw： correlation with body weight （r = 0. 444, P = 0. 036） and scrotal circumference （r = 0. 520, P = 0. 039） ; （2） Ejaculation volume was negatively correlated with mount times （r = -0. 159, P = 0. 035） and erection time （r = -0. 181, P = 0. 023）, semen density was negatively correlated with mating time （r = - 0.211, P = 0.004）, and total sperm count was negatively correlated with erection time （r = - 0. 159 , P = 0. 047）. [Condusion ] The quality of semen had a certain correlation with body size, body weight and sexual behavior.

Risky Sexual Behavior and Its Determinants among Orphan and Vulnerable Children in Addis Ababa, Ethiopia

Back Ground: Risky sexual behavior among orphans and vulnerable children and its associated physical, psychological and social consequences is becoming a major public health concern globally. Objectives: To assess the prevalence of risky sexual behavior and its determinants among orphan and vulnerable children in Addis Ababa. Methodology: A community based cross sectional study was conducted on three support and care giving organizations for orphans and vulnerable children in Addis Ababa, Ethiopia from March to June 2014. A total of 422 orphan and vulnerable children were selected using systematic sampling. Data were collected using pre tested self-administered questionnaire. Logistic regression was used to analyze the data. Result: A total of 407 (96.4%) respondents participated in this study. Among them 112 (27.5%) had sexual intercourse in their life time, of these 50 (44.6%) started sex before the age of 15, 94 (83.9%) had forced sex, 84 (75.0%) had multiple sexual partners, only 16 (14.3%) used condom the first time they had sex and 96 (85.7%) participated in transactional sex. Females were about 3.25 (2.67 - 7.3) times more likely to engage in risky sexual behavior than male respondents, double orphans had 4.32 (2.45 - 9.54) odds of risky sexual behavior compared to their counterparts. Those respondents who had knowledge of HIV transmission and prevention were less likely to be involved in risky sexual behavior 0.58 (0.41 - 0.93). Conclusion: Orphan and vulnerable children are at a higher likelihood of risky sexual behavior. Intervention targeted at multilevel such as orphan survival training, assertive communication skills, sexuality education and education about HIV risk perception, physical, psychological and human right protection, social support, and economic access for basic needs need to be given consideration.

Influence of Prenatal and Postnatal Stress on the Sexual Behavior of Rats

Objective: To evaluate the effects of prenatal and postnatal stress on the sexual behavior of rats. Methods: Thirty-two 2-month-old male Wistar rats were divided as follows: the EG Group (comprised of 10 rats whose mothers underwent gestational stress), the EO Group (11 rats subjected to postnatal stress), and the SE Group (control group, comprised of 11 animals that went through no stress whatsoever). Upon reaching adulthood, these male rates were introduced to females and had their sexual behavior assessed based on the number of mounts. Results: The animals from the EP Group showed significantly fewer mounts (74 ± 24.77, p < 0.05) when compared to those from the EG (108.9 ± 35.27) and SE (99.6 ± 20.76) Groups. Conclusion: The rats that underwent stress during the first days of life mated fewer times than those whose mothers were subjected to stress during pregnancy. The latter had their sexual behavior unaltered.

Rural High School Students’ Sexual Behavior and Self-Esteem

Background: Negative consequences for sexual health may be caused by risky sexual behavior related to attitudes, norms and self-efficacy regarding sexuality. Research has not resulted in a consensus on the associations between self-esteem and adolescents’ sexual behavior. Aims and Objectives: The aim of the study was to describe high school students’ sexual behavior and self-esteem, along with investigating the relationship of attitudes, norms, self-efficacy, and self-esteem to sexual risk behavior. Another aim was to describe and compare gender differences in self-esteem and sexual risk behavior in high school students in a rural context. Methodological Design: A cross-sectional design was used. The participants were 139 high school students, 16 to 18 years of age, sample size was decided by power calculation, and systematic randomized sampling was used. The students replied to a questionnaire about self-esteem, factors affecting sexual risk behavior, and sexual behavior. Results: Swedish high school students reported having few sexual partners, a low use of alcohol along with sex, yet a low consistency in condom use. The students reported both high basic self-esteem as well as earned self-esteem. Basic self-esteem was higher for male students while earned self-esteem was higher for female students. Significant correlations were found between self-esteem and some factors affecting sexual risk behavior related to condom use. Conclusion: High school students exhibited positive sexual behaviors and high levels of self-esteem, yet they put themselves at risk by inconsistent use of condoms. Our findings can contribute the need of to an awareness of the role self-esteem, attitudes, norms and self-efficacy plays in adolescents’ sexual behavior. Nurses working at the youth clinics are in a key position to discuss sexual health issues with adolescents to promote healthy outcomes in sexual health.

Consequences of Different Hysterectomy Techniques in Sexual Behavior——A Systematic Review

We conducted a systematic review of the literature to determine the influence of different hysterectomy techniques in the sexual behavior of women who underwent. We searched CENTRAL (The Cochrane Library), PubMed, SCOPUS, CINAHL and LILACS for studies between the years 1998 and 2010 that prospectively examined the sexuality after hysterectomy. Those that were not randomized controlled clinical trials were excluded. It was not available electronically, it was not related with the outcomes determined, it was not research, but publications before 1998 and study which women realized chemotherapy and radiotherapy. From the 455 identified studies, 9 met inclusion criteria. There was variability in how hysterectomies influence in the sexual behavior. Most of studies considered women who underwent vaginal hysterectomy had fewer changes in sexual behavior. Sexual desire, intercourse frequency and orgasm are the sexual aspects reported by women as more changes experimented after surgery. Findings from this study have implications for healthcare providers and policymakers. Each woman needs an individualized care plan that fits within the context of her life, and there are basic interventions that every woman who underwent hysterectomy should receive. This review draws attention to the need for different care plans for women who underwent different hysterectomy techniques.

Seminal characteristics and sexual behavior in men of different age groups:is there an aging effect?

Aim:To assess the seminal characteristics as well as the sexual behavior of men of various age groups to establish the presence of an aging effect on those characteristics.Methods:Semen samples were collected from men(n=792) undergoing in vitro fertilization or intrauterine insemination in cases of female factor infertility only.Samples were collected using a seminal collection device at intercourse and evaluated manually according to World Health Organiza- tion(WHO)standards.Men were divided into four groups according to their ages:(i)20-30,(ii)31-40,(iii)41-50 and(iv)51-60 years,and their seminal characteristics and responses to a sexual behavior questionnaire were compared. Results:The data showed statistically significant differences in the seminal characteristics tested,most notably in the sperm concentration,motility,grade of motility,hypo-osmotic swelling and normal sperm morphology.Furthermore, the decline in normal sperm morphology with age was more pronounced when rising strict criteria rather than WHO standards.There were also differences in total sperm count,total motile sperm and total functional sperm fiaction (assessed by both WHO and strict criteria).Significant differences were also observed in the sexual behavior patterns in older men in terms of the number of years they have been trying to conceive,sexual flequency and sexual satisfaction. Conclusion:The data clearly illustrate an aging effect on semen characteristics and sexual behavior in men as they age.It is suggested that the aging effect be taken into consideration when proposing normal standard values for semen characteristics in routine semen analysis as outlined by WHO standards.

The Association between Awareness of Sexual Behavior and Cognitive Social Capital among High School Students in Vietnam

Background: Globally, adolescent sexual behavior is a major health concern and the focus of many researches. However, negative attitude towards premarital sex and sense of community belonging have not been examined in relation to adolescent sexual behavior. The purpose of this study was to examine whether these two factors are associated with adolescent sexual behavior. Methods: We conducted a cross-sectional survey of 1672 eleventh grade students from three public high schools in Hanoi, Vietnam. Participants’ sense of community belonging and negative attitude towards premarital sex were assessed through a self-administered questionnaire. We performed multiple logistic regression analyses to examine associations between the cognitive social capital concepts, such as a sense of community belonging. Results: 92.3% of students agreed with a sense of community belonging, but only 14.1% of students accepted premarital sex. A high sense of community belonging was significantly associated with negative attitude towards premarital sex OR (95% CI), male 3.16 (2.3-4.34), female 8.77 (5.38-14.29). After adjusting for a sense of community belonging, the association disappeared between acceptance of premarital sex and sexual experience of peers, proper time to wear a condom, and Rosenberg Self-Esteem Scale score. Conclusion: Cognitive social capital, such as sense of community belonging, was associated with negative attitude towards premarital sex. Therefore, cognitive social capital concepts should be included in sexual behavior and health promotions, especially with adolescents.

An Appraisal of Sexual Behaviors, STI/HIV Prevalence, and HIV Prevention Programs among Truckers in India: A Critical Literature Review

Background: A systematic review portraying the changing pattern of sexual behaviors, STI and HIV prevalence and key strategies curb HIV and STI among truckers in India is lacking. This paper therefore aims to present a chronological review of literature regarding sexual behaviors, STI/HIV prevalence, and various HIV prevention programs implemented among truckers in India. Methodology: Published and unpublished studies (1990-2011) were identified through electronic databases, and hand searching. Results: Most studies on sexual behaviors and STI/HIV prevalence among truckers focused only on drivers and ignored their helpers. Evidences suggest that consistent condom use by truckers with both paid and non-paid female partners has increased during the past decade. Many recent studies suggest that the HIV prevalence among truckers is about 2% and it has been declining slowly during the past decade. The HIV prevention programs among truckers which started with the aim of raising awareness about HIV during early 1990s, have grown multi-folds to encompass not only the standard strategies like mid-media events, interpersonal counselling and STI care for HIV prevention, but also innovations such as the use of business franchisee models, and integrated research and evidence based planning in the program. The possibilities of using new approaches such as male circumcision and the use of pre-exposure prophylaxes are underway. Conclusion: More studies are needed to explore helpers’ vulnerabilities to HIV. Very few studies have attempted to examine the impact of large-scale prevention programs among truckers. Efforts are required to examine the impact of different components of such programs to guide the HIV prevention efforts among truckers in India.

Ethanol Effects on Cortical EEG Correlation and Sexual Behavior in Male Rats

Ethanol affects sexual behavior drastically, as much as its execution as well as its motivation. Ethanol is a central nervous system depressant and the prefrontal cortex (PFC) is one of the cortical areas most sensitive to its effects. This prefrontal area participates in the modulation of the cognitive control, and furthermore, by mean of connections with the parietal cortex (PC) plays an important role in the processing of sexually relevant stimuli. Considering that it has been reported that the ethanol affects the proper functioning of these cortical areas, particularly decreasing the degree of electroencephalographic (EEG) coupling or correlation between them, the aim of this study was to characterize the effect of a low dose of ethanol on EEG correlation, as well determining if this effect is associated with impaired sexual behavior in male rats. Nine male rats unilaterally implanted were simultaneously recorded the EEG from the PFC and PC to calculate the degree of EEG synchronization (correlation, r) between both cortices during the first 40 minutes post administration of 0.75 g/kg of ethanol. At the end of the EEG recording, the males were submitted to copulatory behavior with a receptive female rat. The ethanol administration was associated with a decreased intrahemispheric correlation of the fast bands between PFC and PC, as well as with an increased mount and intromission latency. This data showed that ethanol in moderate doses decreased the coupling degree between cortices. It is likely that this functional disconnection between the PFC and PC after the ethanol administration could be associated with the difficulty in discriminating incentive value of the sexual stimuli so that decreased the sexual motivation but not the performance of the copulatory parameters in the male rat.

Protective Sexual Behaviors and Their Motives, in University Students in the Health Area

Sexually transmitted infections (STIs) and unwanted pregnancy (UP) are becoming a problem that affects significantly the younger segment of the population so, not only in the aspect of health, but in the development of its future life both emotional and school and work. Despite easy access to information, young people still have risky sexual practices. This research highlights protective practices with the aim of developing information and training tools that help them avoid risky behaviors that lead to dangerous situations in health and its future. It was a descriptive study with students who have recently entered of the Faculty of Medicine enrolled in school cycle in 2015 in the bachelor’s degree in Medicine and surgery, Nutrition and dietetics, and Rehabilitation programs who agreed to participate by letter of informed consent to respond to the Instrument for the Evaluation of Psychological Variables and Sexual Risk Behaviors. There were 221 participants, 166 in Medicine and surgery, 28 in Nutrition and dietetics, and 27 in Rehabilitation with an average of 18.6 years, 51% male and 49% female. A protective behavior was not having had sex with penetration (72.3%), due to wanting to have them with whom they are in love and to avoid STIs more frequently in female;another protective behavior was not having had oral sex with occasional partners or unprotected sex workers (15.4%);the reasons were to have wanted to use and that the couple asked him to use it, to avoid sexually transmitted infections because the couple’s sexual history is unknown. Regarding the likelihood of having sexual penetration (SP), participants who have not had it were found that: the men had less possibility to inquire about their partner’s sexual history, to reject the proposal to have SP and to refuse caresses in sensitive areas of the woman’s body;when asked about the likelihood of asking your partner to use a condom in their sexual relations, both men and women agreed that it would be quite likely that they would do so, more frequently in women. It concludes by emphasizing that prevention remains the cheapest, easiest, most reliable and safest tool against STIs and UP.

Sexuality of Repartnered Men and Women in France: Sexual Behaviors, Perceptions, Expectations and Sexual Dysfunctions

Introduction. Although many epidemiological studies on sexuality have been published, none have specifically addressed male and female sexuality in repartnered couples. Aim. To investigate men and women’s sexual behaviors, perceptions and expectations, and the frequency of their sexual dysfunctions, with a focus on repartnered couples, i.e, subjects living with a partner in a stable relationship after divorce or widowhood (including both remarried couples and cohabitating unmarried couples). Methods. Analysis of telephone survey data collected from 1,002 French subjects (483 men, 519 women) ≥35years. Of these, 748 were living with their partner as part of a heterosexual couple. For these subjects, the sexuality of 149 repartnered subjects was compared to that of the other 599 subjects. Main Outcome Measures. A 39-item questionnaire assessing subjects' perceptions, expectations, sexual behaviors and dysfunctions. Results. Compared with other subjects, men and women in repartnered couples had more active sexuality and more interest in sexuality (men 93% vs 80%, P < 0.01, women 73% vs 65%, P < 0.05). They were generally more sensitive to feelings and emotions linked to their sexuality, and these feelings seemed to increase steadily with age. Their sexuality was more attuned to their partner’s pleasure (men 79% vs. 59% P < 0.001, women 50% vs. 34% P < 0.01). Concern for the future of the relationship and for sexuality was equally present for both groups, although repartnered couples were more often concerned about potential inadequacy and conflicts between the two partners. Although repartnered men seemed to be less affected by diminished desire, they had slightly higher rates of premature ejaculation and erectile dysfunction, and considered their quality of life to be more affected by these problems. Conclusion. The sexuality of repartnered couples remains poorly studied, but seems to differ from that of non-repartnered couples. Our findings open interesting avenues of research on the diagnosis and management of repartnered couples.
