Perceptions of teachers regarding sex education in National Capital Territory of Delhi.

A cross sectional study was conducted to find out the knowledge and attitudes of school teachers regarding sex education. Information was collected from 476 senior secondary school teachers belonging both to the government and public schools, selected randomly in National Capital Territory of Delhi using pre-tested close ended questionnaires. A majority of school teachers (73%) were in favour of imparting sex education to school children. Regarding contents of sex education, 90% agreed to the inclusion of reproductive anatomy, physiology including menstruation and birth control measures like condoms and oral pills. However, a majority of school teachers did not want sex education to include topics like abortion, premarital sex and masturbation etc. Fourteen years of age was considered to be the most appropriate for imparting sex education by 28.6% of school teachers. School teachers and doctors were considered by 69.4% and 63.6% of the respondents respectively to be the most appropriate persons for providing sex education.

Impact assessment of school-based sex education program amongst adolescents.

This was a cross-sectional, interview-based study to assess the impact of sex education on the students and the feasibility of such a program. Study sample consisted of 189 students from two secondary schools of Surat city. Impact was assessed by "before and after" administration of questionnaires. Statistical analysis was done by Z tests for difference of means and proportions. Sex education influenced the need perception and the knowledge of the students. After the training, the preferred mean age to start sex education in the two sexes converged to be 15-16 years. Doctors remained the first choice to impart the sex education, followed by school teachers. Knowledge about the STDs and the method(s) of prevention improved significantly (more in boys). Optimum days for conception became known to more students after the training and the gain was more in girls. Increased awareness about the contraceptives (condoms) use was evident in boys and (oral pills and condoms) in girls. The training improved the participation of girls in the post-evaluation program. A positive attitudinal change was observed after the training, towards extra-marital sex. It also removed the myths associated with masturbation. All students were satisfied with the programme, however, two-third of boys considered the duration insufficient.

Drug-induced priapism. Its aetiology, incidence and treatment.

Priapism is characterised by a persistent erection that cannot be relieved by sexual intercourse or masturbation. Although priapism subsides spontaneously in a few days, impotence frequently follows. Both vascular and neural mechanisms are implicated in the pathophysiology of priapism, but it is not clear which initiates the process. Idiopathic cases of priapism are the most frequent (near 50%); other medical conditions that can result in priapism are haematological diseases (mainly sickle cell anaemia and leukaemia), traumatism, and neoplastic processes. Drug-induced priapism comprises about 30% of cases. The drugs most frequently implicated are psychotropic drugs (phenothiazines and trazodone), antihypertensives (mainly prazosin) and heparin. Recently, the intracavernosal injection of vasoactive drugs (papaverine and phentolamine) has been described in patients treated for impotence. With the exception of heparin, an alpha-adrenergic blocking mechanism has been suggested in the priapism-inducing action of these drugs. A significant number of anecdotal case reports link priapism and drugs, and it is possible that certain cases of idiopathic priapism could be reclassified if accurate pharmacological anamnesis were to be performed. Priapism must be considered a urological emergency. Surgical procedures are the most preferred treatment for this condition but, in selected cases, drug treatment seems to be an alternative approach.

[Treatment of paraphilia and sexually aggressive impulsive behavior with the LHRH-agonist leuprolide acetate].

Up to now there are no published results of therapy of paraphilia (Pedophilia, Sadism) and sexual aggressive impulsiveness with LHRH-(luteinizing hormone-releasing hormone) Agonists in the Germanspeaking countries. In this report we describe 11 patients which were treated with the LHRH-Agonist Leuprolide Acetate in a period of 12 months. The patients showed no tendency of sexual aggressive behaviour and reported an evident reduction of penile erection, ejaculation, masturbation, sexual deviant impulsiveness and fantasies. One patient died from suicide. In combination with other treatments LHRH-Agonists seem to be a very promising alternative to cyproterone acetate and its possible carcinogene effects.

[Total infarction of the penis caused by entrapment in a plastic bottle].

Penile strangulation injuries are rare emergency situations, but need a fast urological emergency management for decompression of the penis and for removing of the foreign bodies. Strangulation objects can be metallic or non-metallic objects and are usually used for erotic or autoerotic purposes, for masturbation or increasing erection. We report a case of a 62-year old male with a total infected gangrene of the penis caused by a strangulation of a plastic bottle neck which continued 14 days. A total amputation of the penis was necessary. A perineal urethrostomy was performed as definitive urine diversion. Bacteriologic examination has identified Proteus mirabilis. Thus, a systemic antibiotic therapy was perioperatively applicated. The further course was uneventful with a secondary healing wound.

Systemic and cavernous plasma levels of vasoactive intestinal polypeptide during sexual arousal in healthy males.

Results from basic research scrutiny indicate a role for non-adrenergic, non-cholinergic transmitters, among which there are various peptides, in the physiology of normal male sexual function. Nevertheless, it is not yet known which particular peptides are essentially involved in maintaining sexual arousal and regulating penile tumescence and rigidity in adult males. Vasoactive intestinal polypeptide (VIP), a peptide with smooth muscle relaxing properties, is considered to be one of the factors that contributes to such control. The present study was performed to evaluate the significance of VIP in normal male sexual function. We determined the plasma levels of VIP in the systemic and cavernous blood of 54 healthy adult male volunteers, who were exposed to visual and tactile erotic stimuli in order to elicit penile tumescence and erection. Whole blood was aspirated from the corpus cavernosum and the cubital vein during penile flaccidity, tumescence, rigidity and detumescence, and VIP was quantified in plasma aliquots by means of a radioimmunoassay. Of the 54 volunteers, 16 were permitted to masturbate and ejaculate, and blood was then again withdrawn from the cavernous meshwork and the cubital vein in order to measure VIP. All VIP levels were registered within the normal physiological range from 3.0-30 pmol/l. No increase in median VIP plasma levels was observed in the systemic and cavernous blood when the flaccid penis became rigid. During penile detumescence, mean cavernous VIP level increased to 11.9+/-7.8 pmol/l (baseline: 8.6+/-3.0 pmol/l), whereas VIP remained unaltered in the systemic circulation. Following ejaculation, mean VIP level in the cavernous blood was elevated to 25.3+/-10.9 pmol/l, whereas, in the systemic blood, no significant changes were registered. Our results support the hypothesis that VIP plays a functional role in the mechanism of male sexual arousal. Nevertheless, our data indicate that the peptide is not the main non-adrenergic, non-cholinergic mediator of penile tumescence and rigidity in human males.

Semen analysis in post-pubertal patients with posterior urethral valves: a pilot study.

The issues of sexual function and fertility are becoming relevant in patients with posterior urethral valves (PUV), as more of them reach adulthood. To evaluate the semen of post-pubertal patients with PUV as a determinant of future fertility, all such patients (age >16 years) attending the follow-up urology clinic of our department from 1985 to December 1999 were contacted. Of the nine patients contacted, eight agreed to form the study group. All eight patients were asked to provide a post-masturbation semen sample and urine. Semen was analysed for pH, viscosity, liquefaction time, sperm morphology, sperm count, motility, and agglutination. The patients ages ranged from 16 to 21 years (mean 17.5 years). One patient with chronic renal failure awaiting a renal transplant refused to give a semen sample; two tried but failed to ejaculate on three consecutive visits. Their urine was negative for sperm. Of the five patients who gave semen, the liquefaction time was high in two. pH ranged from 7.2 to 8, sperm counts were 24-80 million. None of the patients had oligospermia. Abnormal sperm agglutination was present in four cases; a higher percentage of immotile sperm was also present in four. Semen abnormalities in the form of increased liquefaction time, abnormal sperm agglutination, and a high percentage of immotile sperm were thus seen in the present study. The bearing of these findings on subsequent sexual function and fertility remains a matter of speculation.

Sexual functioning of people with rheumatoid arthritis: a multicenter study.

The objective of this study is to compare men and women with rheumatoid arthritis (RA) to controls regarding sexual motivation, activity, satisfaction, and specific sexual problems, and to determine the correlation of physical aspects of the disease with sexual functioning. Questionnaire for screening sexual dysfunctions (QSD), self-constructed questionnaire on experienced distress with joints during sexual activities, arthritis impact measurements scales 2 (AIMS2), and the modified disease activity score 28 (DAS 28) were the methods used. RA patients were recruited from a registration base in three Dutch hospitals. Controls were age and sex matched healthy volunteers. A completed questionnaire was sent back by 271 patients (response 23%). Forty-seven men and 93 women were clinically examined to obtain the DAS 28. Male patients felt less sexual desire, and female patients masturbated and fantasized less than controls. Differences in satisfaction were not found. Male and female patients did not experience more sexual problems than controls. Among the women, correlations were predominantly found between age and sexual motivation and activities, among the men between physical health and sexual problems. Up to 41% of the men (4-41 depending on the joints), and up to 51% of the women (10-51 depending on the joints) have troubles with several joints during sexual activities. Medications influencing ejaculation in men correlated with distress with orgasm. Conclusions are that patients are less sexually active than controls and a considerable number of both male and female patients have trouble with their joints during sexual activities. However, patients do not differ from controls regarding sexual satisfaction. Physiological changes due to RA are apparently independent from those on psychological level. It is argued that sexual satisfaction also depends on personal and social factors. In men, physical health and disease activity are more related with sexual problems than in women.

Sexuality before and after male-to-female sex reassignment surgery.

The sexual behaviors and attitudes of male-to-female (MtF) transsexuals have not been investigated systematically. This study presents information about sexuality before and after sex reassignment surgery (SRS), as reported by 232 MtF patients of one surgeon. Data were collected using self-administered questionnaires. The mean age of participants at time of SRS was 44 years (range, 18-70 years). Before SRS, 54% of participants had been predominantly attracted to women and 9% had been predominantly attracted to men. After SRS, these figures were 25% and 34%, respectively.Participants' median numbers of sexual partners before SRS and in the last 12 months after SRS were 6 and 1, respectively. Participants' reported number of sexual partners before SRS was similar to the number of partners reported by male participants in the National Health and Social Life Survey (NHSLS). After SRS, 32% of participants reported no sexual partners in the last 12 months, higher than reported by male or female participants in the NHSLS. Bisexual participants reported more partners before and after SRS than did other participants. 49% of participants reported hundreds of episodes or more of sexual arousal to cross-dressing or cross-gender fantasy (autogynephilia) before SRS; after SRS, only 3% so reported. More frequent autogynephilic arousal after SRS was correlated with more frequent masturbation, a larger number of sexual partners, and more frequent partnered sexual activity. 85% of participants experienced orgasm at least occasionally after SRS and 55% ejaculated with orgasm.

High rates of sexual behavior in the general population: correlates and predictors.

We studied 2450, 18-60-year-old men and women from a 1996 national survey of sexuality and health in Sweden to identify risk factors and correlates of elevated rates of sexual behavior (hypersexuality) in a representative, non-clinical population. Interviews and questionnaires measured various sexual behaviors, developmental risk factors, behavioral problems, and health indicators. The results suggested that correlates of high rates of intercourse were mostly positive, whereas the correlates of high rates of masturbation and impersonal sex were typically undesirable. For both men and women, high rates of impersonal sex were related to separation from parents during childhood, relationship instability, sexually transmitted disease, tobacco smoking, substance abuse, and dissatisfaction with life in general. The association between hypersexuality and paraphilic sexual interests (exhibitionism, voyeurism, masochism/sadism) was particularly and equally strong for both genders (odds ratios of 4.6-25.6). The results held, with a few exceptions, when controlling for age, being in a stable relationship, living in a major city, and same-sex sexual orientation. We conclude that elevated rates of impersonal sex are associated with a range of negative health indicators in the general population.

Exhibitionistic and voyeuristic behavior in a Swedish national population survey.

We examined the prevalence and correlates of self-reported sexual arousal from exposing one's genitals to a stranger (exhibitionistic behavior) and spying on others having sex (voyeuristic behavior) in a representative national sample. In 1996, 2,450 randomly selected 18-60 year-olds from the general population of Sweden were interviewed in a broad survey of sexuality and health. A total of 76 (3.1%) respondents reported at least one incident of being sexually aroused by exposing their genitals to a stranger and 191 (7.7%) respondents reported at least one incident of being sexually aroused by spying on others having sex. Exhibitionistic and voyeuristic behaviors were examined for possible associations with 9 sociodemographic, 5 health, 4 risk-taking, and 17 sexuality variables. Both paraphilia-like behaviors were positively associated with being male and having more psychological problems, lower satisfaction with life, greater alcohol and drug use, and greater sexual interest and activity in general, including more sexual partners, greater sexual arousability, higher frequency of masturbation, higher frequency of pornography use, and greater likelihood of having had a same-sex sexual partner. Consistent with previous research in clinical samples of men with paraphilias, respondents who reported either exhibitionistic or voyeuristic behavior had substantially greater odds of reporting other atypical sexual behavior (sadomasochistic or cross-dressing behavior). There was evidence both for general and specific associations between sexual fantasies and their corresponding paraphilia-like behaviors. The implications of these findings for research on atypical sexual interests, atypical sexual behavior, and paraphilias are discussed.

Sexual behavior in high-functioning male adolescents and young adults with autism spectrum disorder.

Group home caregivers of 24 institutionalized, male, high-functioning adolescents and young adults with Autism Spectrum Disorder, were interviewed with the Interview Sexuality Autism. Most subjects were reported to express sexual interest and to display some kind of sexual behavior. Knowledge of socio-sexual skills existed, but practical use was moderate. Masturbation was common. Many subjects were seeking physical contact with others. Half of the sample had experienced a relationship, while three were reported to have had sexual intercourse. The number of bisexual orientations appeared high. Ritual-sexual use of objects and sensory fascination with a sexual connotation were sometimes present. A paraphilia was present in two subjects. About one third of the group needed intervention regarding sexual development or behavior.

Sexual behavior and response in relation to complications of pregnancy.

A detailed written questionnaire survey of 155 puerperas is reviewed. Sexual and obstetric data were examined for possible associations leading to premature or low-birth-weight infants. Among 25 patients delivering premature infants (16 with babies weighing less than 2,500 grams), no significant association could be made between coitus, orgasm, and/or other sexual experiences and the proximity to the onset of labor. Orgasmic patients appeared to have a consistently lower percentage of early deliveries. No particular method of sexual gratification was unique except that masturbation was consistently associated with a lower risk of prematurity throughout various stages of gestation. Speculations are advanced to explain these observations. Sexual activity appears to be safe throughout pregnancy in almost all patients. Ruptured membranes on admission may be associated with recent sexual stimulation without orgasm.

Testosterone, testis size, seasonality, and behavior in group-living stumptail macaques (Macaca arctoides).

During a 28-month period, data were collected on physiological parameters and sociosexual behavior of 13 adult male members of a large mixed-sex group of stumptail macaques living in an outdoor cage. Monthly measurements of plasma testosterone, testis size, and body weight revealed no systematic seasonality. Seasonal variations did occur in branch shaking and grooming (both with low rates in winter), but not in other behaviors studied (copulation, masturbation, aggression). Dominance ranks were stable throughout the study period and were not significantly correlated with mean testosterone levels. Temporal fluctuations in behavioral frequencies did not parallel testosterone fluctuations. Interindividual differences in behavioral frequencies were often correlated with dominance rank, but not with testosterone levels.

Low sexual desire in women: the role of reproductive hormones.

The role of reproductive hormones in mediating sexual desire in healthy women is still unclear. Elucidation was sought in this study by comparing the hormonal milieu of two groups of subjects with markedly different levels of sexual desire. Seventeen women ages 27-39 who met DSM III-R criteria for severe, persistent, and generalized loss of desire (hypoactive sexual desire disorder, HSD), but had no other current psychological or medical problem, were compared to 13 healthy, sexually active women. All subjects and spouses were interviewed extensively to determine the women's sexual desire and responsiveness. Blood samples were drawn every 3 to 4 days for one menstrual cycle and were analyzed by RIA for testosterone, SHBG, estradiol, progesterone, prolactin, and luteinizing hormone. Results indicated that the HSD women's gonadal hormones fluctuated normally over the menstrual cycle, were within normal limits for each cycle phase, and were never significantly different from those of controls. Neither testosterone, non-SHBG bound testosterone, nor prolactin differentiated between the HSD women with the most and least severe HSD parameters (e.g., frequency of fantasy, masturbation, or female-initiated coitus), nor between women with lifelong and acquired HSD. The present findings did not provide evidence that reproductive hormones are important determinants of individual differences in the sexual desire of these eugonadal women.

Comments by the 'Information by Phone' Department of the Sex Medical Institute on the telephone calls related to sexuality and contraception.

The present study which was carried out by the Sex Medical Institute has been based on 5252 telephone calls related to sexual or contraception matters, which were received in the period February 1989 to July 1991. Of the calls, 58.8% came from men and 41.2% from women. The main topics of the questions concerned masturbation (frequency, guilts), anatomy of the genital system (anxiety and concern on the length of the penis, virility, femininity), the first sexual experience (fear, anxiety of failure).

Psychologic profiles of and sexual function in women with vulvar vestibulitis and their partners.

OBJECTIVE: To compare psychologic profiles of women with vulvar vestibulitis and their partners with a normal population, and to identify sexual dysfunction in women and their partners. METHODS: Forty-three women with vulvar vestibulitis and 38 partners, recruited from a gynecology outpatient clinic, completed the Symptom Check List-90, the Short Dutch Version of the Minnesota Multiphasic Personality Inventory, the Maudsley Marital Questionnaire, and the Questionnaire for Screening Sexual Dysfunctions. RESULTS: The women with vulvar vestibulitis scored significantly higher on the somatization and shyness subscales than a normal population. They didn't differ in respect to their current level of psychologic distress, extraversion, risk of psychopathology, and marital satisfaction. Their partners had significantly lower scores for psychopathology than a normal population. They didn't differ from a normal population in respect to their level of psychologic distress, extraversion, shyness, somatization, and marital satisfaction. Women with vulvar vestibulitis reported more frequent problems and higher distress with genital pain, lubrication, sexual arousal, and negative emotions in the sexual interaction with the partner. During masturbation, however, they reported less frequent problems and distress. The partners of these women reported nearly no problems or distress in either sexual situation. CONCLUSION: Women with vulvar vestibulitis and their partners seem in general to be psychologically healthy, although vulvar vestibulitis may be associated with a situationally defined sexual dysfunction for the women.

Circumcision. A medical or a human rights issue?

American parents and health care professionals are faced with medical/ethical dilemmas regarding whether or not to respect the natural integrity of the male newborn's body. In the English-speaking countries, where circumcision of infants was initially adopted to prevent masturbation, medical "reasons" were postulated to justify a practice most of the world has never considered. This resulted in a spectrum of medical recommendations for surgical removal of normal genital tissue in all male newborns to prevent diseases (foreskin inflammation, urinary tract infections, and sexually transmitted diseases) that could be effectively treated medically without the risks of surgery. Only by denying the existence of excruciating pain, perinatal encoding of the brain with violence, interruption of maternal-infant bonding, betrayal of infant trust, the risks and effects of permanently altering normal genitalia, the right of human beings to sexually intact and functional bodies, and the right to individual religious freedoms can human beings continue this practice.
