[A study on the relationship between pre- and post-hysterectomy sexual behavior differences and the sexual satisfaction of women who have had a hysterectomy].

The objective of this study was to provide a basis for sexual counselling and education for women who have had a hysterectomy. This was a cross sectional descriptive correlation study. There were 230 subjects in the study. The time period from the hysterectomy varied from one month to eighteen months. The subjects were selected by a convenient sampling method. The tool for this study was developed by the researcher through a literature review, consultation from 36 women who have had a hysterectomy and nursing faculty. A pilot study was done to determine the necessary modifications. Data collection was done between Sept. 1987 and Dec. 1987 using a mailed questionnaire. The results of this study are summarized as follows; 1. The differences between pre-post hysterectomy sexual behavior in frequency was that all the sexual behaviors were decreased; the decreased rate of coitus was 20.7%, of kissing or embracing 10.9%, of fondling of sexual organs 8.7%, of female prone-position 3.3%, of petting 7.7%, of sexual day dream 1.0%. 2. For the low income group, the sexual behavior with the most significant decrease in frequency was fondling the sex organs (t = 2.21, p less than .05). For the housewife group, it was a decrease in the one of the female prone position (t = -2.02, p less than .05). For the group under the age of 39, it was petting (t = -2.13, p less than .05). The housewife group showed an increase in sexual day dreams as compared to the group having a job (t = -3.12, p less than .01). The group that did not received the post-op information, showed a significant decrease in kissing or embracing behavior (t = 2.73, p less than .01), and male prone position (t = -2.46, p less than .01), and also the group that did not receive the pre-op information showed a significant decrease of male prone position (t = -2.19, p less than .05), and also of petting (t = -2.95, p less than .01). 3. The relationship between sexual behavior pre-post hysterectomy differences and sexual satisfaction only showed a significant correlation for the sexual behavior of coitus (r = -2.012, p less than .001), and fondling of sex organs (r = -.1121, p less than .05). In conclusion, although there were a decrease in all sexual behavior after the hysterectomy, the difference between the pre hysterectomy sexual behavior and the post hysterectomy sexual behavior correlated with sexual satisfaction for only of the two behaviors.

The role of mesencephalic tegmentum in regulating female rat sexual behaviors.

Feminine sexual behaviors were tested in estradiol benzoate (EB) and progesterone (P) primed ovariectomized rats following four types of radiofrequency lesions in the midbrain tegmentum. The dorsomedial lesion (DML) which destroyed the ventromedial central gray including the dorsal raphe nucleus and adjacent area induced high sexual receptivity in the females primed with low dose (0.5 micrograms) of EB-P. All females with DML exhibited lordosis and ear wiggling, the mean lordosis quotient (LQ) being significantly higher than that of castrated controls or sham operated rats. Sexual receptivity in females with ventromedial tegmental lesion was not significantly different from those of the control and sham groups. In contrast to the medially lesioned groups, the mean LQ was low in the animals with bilateral lateral tegmental lesions even when the dose of EB was increased to 2 micrograms which was sufficient to induce high sexual receptivity in castrated and sham operated control females. In the animals with dorsolateral tegmental lesions (DLL), a much more severe loss of lordosis was seen than in those with ventrolateral tegmental lesions (VLL). None of the DLL females displayed sexual behavior throughout the present experiments. These results lead us to conclude that the midbrain dorsomedial tegmental area (ventral central gray and the adjacent area) is concerned with female sexual behavior inhibiting system, whereas the lateral tegmental area may be involved in the facilitatory system.

The diagnostic utility of sexual behavior problems in diagnosing sexual abuse in a forensic child abuse evaluation clinic.

OBJECTIVE: This study examined the utility of sexual behavior problems as a diagnostic indicator of sexual abuse. The hypothesis was that sexual behavior problems are multiply determined and consequently are variably related to sexual abuse in a clinical sample. METHOD: A sample of 247 children evaluated for sexual abuse at a multidisciplinary forensic child abuse evaluation clinic were included. Results from the Child Behavior Checklist (CBCL) and the Child Sexual Behavior Inventory (CSBI) were analyzed and compared to the results of a structured abuse assessment performed independent of these scores. RESULTS: The forensic team assessment found evidence of sexual abuse in 25% of cases, and no evidence in 61%. Children in this sample exhibited an elevated level of both sexual and nonsexual behavior problems. However, considerable variability was noted in sexual behavior problem scores. Thus, in this study a high score or a low score had no relationship to the diagnosis of sexual abuse. Indeed, nonsexually abused children were just as likely to have high CSBI scores as sexually abused children. CONCLUSIONS: This study found no significant relationship between a diagnosis of sexual abuse and the presence or absence of sexual behavior problems in a sample of children referred for sexual abuse evaluation. The finding suggests that community professionals should use caution in relying on sexual behavior problems as a diagnostic indicator of abuse.

Polymorphisms in the dopamine D4 receptor gene (DRD4) contribute to individual differences in human sexual behavior: desire, arousal and sexual function.

Although there is some evidence from twin studies that individual differences in sexual behavior are heritable, little is known about the specific molecular genetic design of human sexuality. Recently, a specific dopamine D4 receptor (DRD4) agonist was shown in rats to induce penile erection through a central mechanism. These findings prompted us to examine possible association between the well-characterized DRD4 gene and core phenotypes of human sexual behavior that included desire, arousal and function in a group of 148 nonclinical university students. We observed association between the exon 3 repeat region, and the C-521T and C-616G promoter region SNPs, with scores on scales that measure human sexual behavior. The single most common DRD4 5-locus haplotype (19%) was significantly associated with Desire, Function and Arousal scores. The current results are consistent with animal studies that show a role for dopamine and specifically the DRD4 receptor in sexual behavior and suggest that one pathway by which individual variation in human desire, arousal and function are mediated is based on allelic variants coding for differences in DRD4 receptor gene expression and protein concentrations in key brain areas.

Sexual behavior in the cockroach genera Periplaneta and Blatta. III. Aggression and sexual behavior.

Relationships between aggression and sexual behavior were examined in 6 cockroach species (genera Periplaneta and Blatta) in a descriptive manner. Aggressive encounters were classified according to intensity level. The behaviors themselves were scrutinized for differences according to varying contexts such as food and water deprivation and sexual situations. Sexual and species differences in aggressive behaviors were analyzed. Sexual encounters in cockroaches are considered as conflict situations in which many of the sexual behaviors of male male serve to neutralize aggressive behaviors of the female. Major adaptations include a male pheromene, tergal glands and defensive manoeuvering with body and legs.

Olfactory bulb removal decreases androgen receptor binding in amygdala and hypothalamus and disrupts masculine sexual behavior.

In these experiments we examined the relationship between olfactory bulb removal, limbic system androgen receptor binding and male copulatory behavior. Sexually experienced male rats were castrated, and implanted with two 10 mm testosterone-filled silastic capsules. Animals then underwent either bilateral olfactory bulb removal (BOB) or sham surgery (Sham). Beginning 1-2 days postoperatively both BOB and Sham operates were given 4 tests for male copulation on alternate days. Less than 40% of BOB males ejaculated. In contrast, 80-100% of sham operates continued to ejaculate throughout the 4 postoperative tests. Cell nuclear androgen receptor binding was assessed in amygdala, hypothalamus, preoptic area and septum 1-2 and 8-9 days after either bulbectomy or sham surgery. We found that olfactory bulbectomy significantly reduces androgen receptor binding in amygdala and hypothalamus. The reduction in androgen receptor binding in amygdala occurs within 1-2 days following olfactory bulb removal and is correlated with the disruption of ejaculatory activity. These data suggest that the neuromodulation by olfactory bulb input to androgen-concentrating neurons in the amygdala and hypothalamus is necessary for effective copulation in male rats.

Sexual behavior and experience of sexual coercion among secondary school students in three states in North Eastern Nigeria.

BACKGROUND: Interest in the reproductive health of adolescents continues to grow throughout the world. Few studies had explored the reproductive health knowledge, sexual behavior and experience of sexual coercion among secondary school students in North Eastern states of Nigeria. The objectives of this descriptive survey were to collect data to plan appropriate interventions that meet the reproductive health knowledge, service and skills needs of students in Bauchi, Borno and Gombe states. METHODS: Face-to-face interviews were conducted for 624 consenting students who were randomly selected from eighteen secondary schools using an 83-item structured questionnaire. Data were collected on demographic profile, reproductive health knowledge, sexual behavior and experience of sexual coercion. RESULTS: The mean age of the respondents was 16.5 years. There were slightly more males (52%) than females (48%). Students' knowledge about reproductive health was generally low even though girls had better knowledge than boys. Thirteen percent of the entire students had had sexual experience; significantly more males (19%) than females (6%) had done so (p < 0.001). Among boys the age at sexual debut ranged from 10-26 with a mean of 15.7 and median of 16. By contrast, the age at first sex among girls ranged from 10 to 18 years with a mean and median of 16.1 and 17 years respectively. Only 24% of those who were sexually active used a condom during their last sexual encounter. Overall 11% of the students reported that they had been tricked into having sex, 9% had experienced unwanted touch of breast and backside, and 5% reported rape. CONCLUSION: Students low reproductive health knowledge and involvement in risky sexual activities predispose them to undesirable reproductive health outcomes.

Using drugs to facilitate sexual behavior is associated with sexual variety among injection drug users.

Little normative data exist about the frequency and variety of sexual behavior of injection drug users. Sexual behaviors of a group of 313 injection drug users (225 men and 88 women) were assessed by a structured interview at the start of an acquired immune deficiency syndrome prevention project. Celibacy was reported by 12.3% of men and 26.9% of women in the year before the initial interview. Male injection drug users who had been sexually active reported a mean number of 4.61 (median, 2.0) female sexual partners in the previous year; sexually active women reported a mean number of 5.28 (median, 1.0) male sexual partners. Sexually active men and women reported median condom use frequency at 0% of vaginal intercourse events (mean for men, 10.31%; mean for women, 14.48%). Male injection drug users who reported using drugs to help them relax for sex, to enhance sexual performance, or to meet sexual partners reported greater frequency of anal intercourse, fellatio, and cunnilingus, less relative frequency of vaginal intercourse, more sexual partners, and greater involvement in being paid for sex and paying for sex than did men who did not report using drugs to enhance sex. Men who used drugs to enhance sex also reported higher frequency of use of a number of different drug classes than men who did not use drugs to enhance sex. For women, using drugs to enhance sex was related to greater frequency of anal intercourse and having more sexual partners. Implications for treatment of drug abusers and future research are discussed.

[Sexual behaviors and incidence of sexual and reproductive health programs among poor secondary students and public university students in Cali, Colombia].

In order to qualitatively evaluate sexual behaviors or practices and the incidence of sexual and reproductive health programs in adolescent and postadolescent users educated in Cali, Colombia, two quota samples were carried out, one in schools in poor neighborhoods of the city and one at Valle University (UNIVALLE). In addition, a limited number of twelve open interviews was made among two different student population groups, the schools and the university. The study addresses the sexual behaviors of adolescents and postadolescents, contraceptive methods and prevention of STDs and HIV/AIDS, and the uses of sexual and reproductive health programs by both populations, controlling for social class (socioeconomic stratum), gender, and race. Two sexual and reproductive health programs were taken as reference: that of PROFAMILIA (Pro-Wellbeing of the Colombian Family Association), and the sexual and reproductive health program of the University Medical Service of the UNIVALLE. Results show how the behaviors and responses to sexual and reproductive health programs are mediated by multiple sociological categories that orient the analysis.

The effect of abortion legalization on sexual behavior: evidence from sexually transmitted diseases.

Unwanted pregnancy represents a major cost of sexual activity. When abortion was legalized in a number of states in 1969 and 1970 (and nationally in 1973), this cost was reduced. We predict that abortion legalization generated incentives leading to an increase in sexual activity, accompanied by an increase in sexually transmitted diseases (STDs). Using Centers for Disease Control data on the incidence of gonorrhea and syphilis by state, we test the hypothesis that abortion legalization led to an increase in sexually transmitted diseases. We find that gonorrhea and syphilis incidences are significantly and positively correlated with abortion legalization. Further, we find a divergence in STD rates among early legalizing states and late legalizing states starting in 1970 and a subsequent convergence after the Roe v. Wade decision, indicating that the relation between STDs and abortion is casual. Abortion legalization accounts for about one-fourth of the average disease incidence.

[Psychological stress and sexual behavior in male rats. II. Effect of psychological stress on dopamine and its metabolites in the critical brain areas mediating sexual behavior].

We have reported that sexual behavior of male rats is impaired by long-term psychological stress. We measured dopamine (DA) and its metabolites (3,4-dihydroxyphenylacetic acid, DOPAC, and homovanillic acid, HVA) in the brain of rats which were exposed to the long-term stress. Our experiment was focused on the medial preoptic area (MPOA), which is perhaps the single most critical area of the brain mediating sexual behavior, the amygdala, the substantia nigra, the striatum, the nucleus accumbens and the cortex. In the MPOA, dopamine, DOPAC, and HVA decreased; in the substantia nigra and amygdala, dopamine and HVA decreased; and in the striatum and nucleus accumbens only HVA decreased after long-term psychological stress. In the cortex, however, no evidence of change was recognized. These changes indicate low activity of dopamine neurons which have an important role in male sexual behavior. Therefore, we suspect that exposure of male rats to psychological stress leads to a decrease in the activity of dopamine neurons, especially in the MPOA, amygdala, and substantia nigra, impairing their sexual behavior.

Child Sexual Behavior Inventory: normative, psychiatric, and sexual abuse comparisons.

A normative sample of 1,114 children was contrasted with a sample of 620 sexually abused children and 577 psychiatric outpatients on the Child Sexual Behavior Inventory (CSBI), a 38-item behavior checklist assessing sexual behavior in children 2 to 12 years old. The CSBI total score and each individual item differed significantly between the three groups after controlling for age, sex, maternal education, and family income. Sexually abused children exhibited a greater frequency of sexual behaviors than either the normative or psychiatric outpatient samples. Test-retest reliability and interitem correlation were satisfactory. Sexual behavior problems were related to other generic behavior problems. This contributed to the reduced discrimination between psychiatric outpatients and sexually abused children when compared to the normative/sexually abused discrimination.

Effects of chronic mild stress on sexual behavior, locomotor activity and consumption of sucrose and saccharine solutions.

Many symptoms of human depressive disorders are also observed in animals after exposure to unpredictable stressors. The chronic mild stress (CMS) paradigm was developed in order to better model the human situation by using chronic mild stressors over a longer period. It is claimed that the model induces anhedonia in the animals, a core symptom of depression in humans. Despite the fact that the CMS model has a high degree of face validity, there are a number of laboratories in which the establishment of the model is less reliably observed. We have examined behavior (sexual activity and open field activity) together with hedonic measures (sucrose and saccharine intake) after exposure to CMS. CMS decreased male sexual activity (e.g. reduced capability to ejaculate) and increased activity in an open field test. The hedonic measures showed diverging results after CMS in our laboratory. Sucrose consumption was reduced, while saccharine consumption did not show a comparable change. It is concluded that CMS induces comparable alterations to some depression-like symptoms in humans. Saccharine consumption is not a reliable indicator of the hedonic responsiveness to CMS.

Telencephalic connections of the sexually dimorphic area of the gerbil hypothalamus that influence male sexual behavior.

The sexually dimorphic area (SDA) of the gerbil hypothalamus is essential for mating in male gerbils. To determine if it affects mating through its connections with the ventral part of the lateral septal nucleus (LSv), the caudal part of the medial bed nucleus of the stria terminalis (caudal BSTm), or the medial amygdala-amygdalohippocampal area (MA-AHi), these connections were severed. Unilateral cell-body lesions were made in the SDA and in the contralateral LSv, caudal BSTm, or MA-AHi. Controls received the same lesions ipsilaterally. Other gerbils received lesions in the caudal BSTm and contra- or ipsilateral MA-AHi. Only contralateral lesions of the SDA and caudal BSTm severely impaired mating. Because contralateral lesions of the SDA and MA-AHi, or BSTm and MA-AHi, did not mimic this effect, the BSTm neurons that are needed for male sexual behavior through their connections with the SDA do not simply relay information to or from the MA-AHi.

Sociodemographic characteristics and sexual behavior of bisexual men in France: implications for HIV prevention. The French National Survey on Sexual Behavior Group.

The French National Survey on Sexual Behavior was used to identify sociodemographic characteristics and sexual behavior of bisexually active men, as distinct from both homosexually and heterosexually active men. In regard to number of partners and frequency of unprotected vaginal sex, bisexuals were similar to multipartnered heterosexuals. On sociodemographic criteria, they differed from both homosexuals and heterosexuals. Bisexual men reported fewer partners than homosexuals but seemed more likely to engage in risk behavior related to the acquired immunodeficiency syndrome (AIDS), and they were less likely to have ever had a human immunodeficiency virus (HIV) test. These results justify prevention efforts specially adapted for bisexuals.

The sexual behaviors of African American women living with HIV disease: is perceived HIV status altering sexual behavior?

The purpose of the study was to compare the sexual risk behaviors of heterosexual African American women living with HIV disease to women who perceive themselves to be HIV negative using a comparative descriptive design. Data were collected using a demographics questionnaire developed by the investigator and the Safe Sex Behavior Questionnaire (SSBQ). The HIV-positive sample was collected in two public service agencies that provide case management for HIV-positive individuals. The HIV-negative sample was collected in the surrounding community, populated primarily by low-income African Americans. The HIV-positive group demonstrated lower levels of income and education. Scores on the SSBQ indicated no statistical difference between the high-risk sexual behaviors of the HIV-positive and HIV-negative groups. No statistically significant difference was found in the reported past sexual experiences of the two groups, although mean SSBQ scores were higher in the HIV-positive group. The levels of sexual behaviors in both groups were consistent with the high-risk sexual behaviors of HIV-negative persons reported in the literature. This illustrates the need for nursing as a profession to improve programs directed toward altering the behaviors of those at high risk of contracting or transmitting HIV disease.
