[Orgasm and its impact on quality of life after radical prostatectomy].

INTRODUCTION: Orgasm is a neurophysiological event, which produces bulbous cavernous muscle contraction that usually coincided with ejaculation. The aim of this study was to assess the orgasm's presence and quality in patients treated with radical prostatectomy, as well as its impact on quality of life of these patients. METHOD: The medical records of 152 patients with radical prostatectomy were reviewed retrospectively. Patients were operated between january 1999 and december 01, with an average age of 64.4 (44-75) years and the follow-up period was 33 (21-45) months. 42 (31.6%) patients showed erectile dysfunction (ED) previous to surgery. The research was performed by a personal interview through a questionnaire. RESULTS: 134 patients (96.4%) treated showed post operative ED, 91.6% of patients had stable relationship and 44.4% have sexual intercourse, 23.3% masturbation only and 32.3% no sexual activity. 84 patients (55.2%) were not interested in receiving treatment and 25 (16.4%) referred a reduced libido. Concerning to orgasm sensation, 140 patients (92.1%) preserved a subjectively normal orgasm, 4 (2.6%) referred lack of it and 8 (5.2%) a weakened or anomalous sensation. Furthermore 24 patients (15.7) had urine loss during orgasm. CONCLUSIONS: After radical prostatectomy, both the orgasmic function and libido were kept by the majority of patients despite the neuro vascular bundle damaged caused. Only a minority of patients having urine loss, as a consequence of surgical procedure.

Differences between Internet samples and conventional samples of men who have sex with men: implications for research and HIV interventions.

The Internet is becoming a new erotic oasis for obtaining sex online or in person. We reviewed the literature on cybersex and compared differences in data from samples of homosexually active men obtained on identical questionnaires from a conventional written questionnaire, distributed through the mailing and contact lists of a large national gay organization in Sweden, and through the same organization's website and chat room. A total of 716 written questionnaires and 678 Internet questionnaires were obtained. The Internet sample was younger, more likely to live in small towns or cities, live with parents or a girlfriend, and have lower formal education. They are less likely to have previous sexual experience solely with other men (one in three of the Internet sample vs. 1 in 14 of the written sample defined themselves as bisexual) and more likely to visit erotic oases such as bathhouses, video clubs and erotic movie houses. They also visited Internet chat rooms more frequently (86% of the Internet sample vs. 50% of the written sample). One third of the Internet sample wanted the opportunity to talk with an expert about HIV compared with a quarter of the written sample. Sexual practices between the two samples were generally similar, although the Internet sample reported significantly less body contact, kissing, hugging, mutual masturbation, and more condom use for anal intercourse with steady partners. Over four times as many of the Internet samples reported sex with women in the past year as the written sample. These data indicate that Internet data collection is feasible and that this mode of data collection, despite the nonrandom and self-selected nature of both types of samples, is likely to be more significantly oriented toward the young, geographically more isolated, and more behaviorally and self-identified bisexual respondent than conventionally distributed written questionnaires.

A preliminary report relating frequency of vaginal intercourse to heart rate variability, Valsalva ratio, blood pressure, and cohabitation status.

The relationship between recalled frequency of penile-vaginal intercourse (FSI) and resting heart rate variability (HRV; an index of parasympathetic tone), resting diastolic blood pressure (DBP) and heart rate (HR) response to the Valsalva maneuver was examined in 51 healthy adults aged 20-47 (subjects scoring above the 86th percentile on the Lie scale of the Eysenck Personality Inventory (EPI) were excluded). As hypothesized, greater HRV and lower DBP were both associated with greater FSI (but not masturbation or non-coital sex with a partner) in cohabiting subjects, but not in non-cohabiting subjects. Valsalva ratio was unrelated to sexual behavior. Results are discussed in terms of both the modulating role of blood pressure on a number of psychological functions and the role of parasympathetic tone in HRV, FSI, and possibly pair-bonding.

Coitus-induced orgasm stimulates prolactin secretion in healthy subjects.

Previous data have indicated that orgasm produces marked alterations in plasma prolactin concentrations in men and women. Thus, the current study aimed to extend these data by examining prolactin response to coitus in healthy males and females. Ten pairs of healthy heterosexual couples participated in the study. Blood was drawn continuously for 20 min before, during, and until 60 min following sexual intercourse and orgasm. Plasma was subsequently analysed for prolactin concentrations. Coitus-induced orgasm produced a marked elevation of plasma prolactin in both males and females. Plasma prolactin concentrations remained elevated 1 h following orgasm. These data, together with previous evidence that masturbation-induced orgasm produces pronounced, long-lasting increases in plasma prolactin concentrations in both males and females, suggest a role for acute prolactin alterations in modifying human sexual desire following orgasm.

Neuroendocrine and cardiovascular response to sexual arousal and orgasm in men.

Data regarding the neuroendocrine response pattern to sexual arousal and orgasm in man are inconsistent. In this study, ten healthy male volunteers were continuously monitored for their cardiovascular and neuroendocrine response to sexual arousal and orgasm. Blood was continuously drawn before, during and after masturbation-induced orgasm and analyzed for plasma concentrations of adrenaline, noradrenaline, cortisol, luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin, growth hormone (GH), beta-endorphin and testosterone. Orgasm induced transient increases in heart rate, blood pressure and noradrenaline plasma levels. Prolactin plasma levels increased during orgasm and remained elevated 30 min after orgasm. In contrast, none of the other endocrine variables were significantly affected by sexual arousal and orgasm.

Neuroendocrine response to film-induced sexual arousal in men and women.

The psychoneuroendocrine responses to sexual arousal have not been clearly established in humans. However, we have demonstrated previously that masturbation-induced orgasm stimulates cardiovascular activity and induces increases in catecholamines and prolactin in blood of both males and females. We presently investigated the role of orgasm in producing these effects. Therefore, in this study parallel analysis of prolactin, adrenaline, noradrenaline, and cortisol concentrations, together with cardiovascular variables of systolic/diastolic blood pressure and heart rate were undertaken during film-induced sexual arousal in nine healthy adult men and nine healthy adult women. Blood was drawn continuously via an indwelling cannula and connected tubing system passed through a mini-pump. In parallel, the cardiovascular parameters were recorded continuously via a computerised finger-cuff sensor. Subjective sexual arousal increased significantly in both men and women during the erotic film, with sexual arousal eliciting an increase in blood pressure in both males and females, and plasma noradrenaline in females only. In contrast, adrenaline, cortisol and prolactin levels were unaffected by sexual arousal. These data further consolidate the role of sympathetic activation in sexual arousal processes. Furthermore, they demonstrate that increases in plasma prolactin during sexual stimulation are orgasm-dependent, suggesting that prolactin may regulate a negative-feedback sexual-satiation mechanism.

Construction and psychometric properties of sexuality scales: sex knowledge, experience, and needs scales for people with intellectual disabilities (SexKen-ID), people with physical disabilities (SexKen-PD), and the general population (SexKen-GP).

This study reports on the development and assessment of the psychometric properties of three measures to assess sexual knowledge, experience, feelings, and needs. The first was designed to assess the Sexual Knowledge, Experience, Feelings, and Needs of people with mild intellectual disabilities (SexKen-ID). The two parallel measures were designed to assess the same areas of sexuality among people with physical disabilities (SexKen-PD) and among the general population (SexKen-GP). The areas of sexuality included in the scales were Friendship, Dating and Intimacy, Marriage, Body Part Identification, Sex and Sex Education, Menstruation, Sexual Interaction, Contraception, Pregnancy, Abortion and Child-birth, Sexually Transmitted Diseases, Masturbation, and Homosexuality. Generation of the items in these scales is described in Studies 1-3. Study 4 describes the evaluation of the psychometric properties of the scales. Sixty-six people with intellectual disabilities, 54 people with physical disabilities, and 100 people from the general population completed the scales. Test-retest reliabilities were also calculated with 30 people with intellectual disabilities, 30 people with physical disabilities, and 30 people from the general population. These data demonstrate the good psychometric properties of the scales and so their simitability for assessing the sexual knowledge, experience, feelings, and needs of people with disability.

Nurse-midwives' attitudes towards adolescent sexual and reproductive health needs in Kenya and Zambia.

Adolescent sexuality is a highly charged moral issue in Kenya and Zambia. Nurse-midwives are the core health care providers of adolescent sexual and reproductive health services but public health facilities are under-utilised by adolescents. The aim of this study was to investigate attitudes among Kenyan and Zambian nurse-midwives (n=820) toward adolescent sexual and reproductive health problems, in order to improve services for adolescents. Data were collected through a questionnaire. Findings revealed that nurse-midwives disapproved of adolescent sexual activity, including masturbation, contraceptive use and abortion, but also had a pragmatic attitude to handling these issues. Those with more education and those who had received continuing education on adolescent sexuality and reproduction showed a tendency towards more youth-friendly attitudes. We suggest that critical thinking around the cultural and moral dimensions of adolescent sexuality should be emphasised in undergraduate training and continuing education, to help nurse-midwives to deal more empathetically with the reality of adolescent sexuality. Those in nursing and other leadership positions could also play an important role in encouraging wider social discussion of these matters. This would create an environment that is more tolerant of adolescent sexuality and that recognises the beneficial public health effect for adolescents of greater access to youth-friendly sexual and reproductive health services.

The sexual practices of Asian and Pacific Islander high school students.

PURPOSE: To describe the sexual behaviors, beliefs, and attitudes of Asian and Pacific Islander California high school students and to compare them to other racial/ethnic groups. METHODS: Data were collected from an anonymous self-administered survey of 2026 ninth to 12th graders in a Los Angeles County school district; 186 of the respondents described themselves as Asian and Pacific Islander. The survey was conducted in April 1992. RESULTS: A higher percentage of Asian and Pacific Islander adolescents (73%) compared with African-American (28%, p < .001), Latino (43%, p < .001), white (50%, p < .001), and other (48%, p < .001) adolescents had never had vaginal intercourse. Asian and Pacific Islander adolescents were less likely than other adolescents to report having engaged in heterosexual genital sexual activities during the prior year, including masturbation of or by a partner, fellatio with ejaculation, cunnilingus, and anal intercourse. Few students in any group reported homosexual genital sexual activities. Asians and Pacific Islanders who had had vaginal intercourse were more likely than most other groups to have used a condom at first vaginal intercourse, but Asians and Pacific Islanders had not used condoms more consistently over the prior year. Asians and Pacific Islanders were more likely to expect parental disapproval if they had vaginal intercourse and less likely to think that their peers had had vaginal intercourse. CONCLUSIONS: Asian and Pacific Islander high school students in one California school district appear to be at lower sexual risk than other racial/ethnic groups. However, a large minority are engaging in activities that can transmit disease and lead to unwanted pregnancy. Therefore, current efforts to develop culturally sensitive clinical and community-based approaches to sexual risk prevention should include Asians and Pacific Islanders.

Study in sexuality of medical college students in India.

PURPOSE: In India, talking about sex is taboo. Little is known about the knowledge, attitude, and sexual behavior of adolescents. This study was carried out with the purpose of examining: (a) the knowledge of medical students about sex, (b) the sources of learning about sex, and (c) the sexual behavior and practices of young adults. METHODS: This study was carried out among the undergraduate students of a medical college in Delhi. A pretested, semiclosed-type questionnaire was voluntarily filled out by the students. Confidentiality and secrecy was assured. RESULTS: Of 500 students, 73% participated in the study. Knowledge regarding sexual intercourse, masturbation, contraception, and sexually transmitted diseases was satisfactory among 70%, 74.8%, 83.5%, and 92.6% of the respondents, respectively. Common source of knowledge about sex were friends (74.5%), pornographic films (56.2%), and books and magazines (55.1%). Only one fifth could communicate with teachers, parents, and persons of the other gender about sex. About 417 of the students viewed homosexuality as normal behavior. Sexual intercourse had been experienced by 11.8% of respondents. The mean age of first sexual intercourse was 17.5 years. Eighty-five percent strongly favored introduction of sex education at school level. CONCLUSION: Evidence is provided for the need to improve knowledge about different aspects of sex among a sample of Indian medical students.

The African-American church: a potential forum for adolescent comprehensive sexuality education.

PURPOSE: To investigate the attitudes and beliefs of clergy from African-American churches towards sexuality education and the provision of sexuality education in their churches. METHODS: A pilot study was designed to survey a convenience sample of clergy leaders from African-American churches about their young adolescent members. The survey asked about priority health topics, prevalence of sexual and drug risk behavior and the clergy's desire for health education programs. The churches were located in a county (1990 population approximately 200,000, 40% African-American) in the southeastern United States. RESULTS: The respondents' highest priority issues were drugs, violence, HIV/AIDS, pregnancy and alcohol. Many (76%) had discussed one or more of these issues in church. All respondents wanted additional health seminars for their adolescents, though some clergy (30%) excluded some sexual topics (i.e., anal sex, bisexuality, homosexuality, masturbation, oral sex). Only 6% would make condoms available in their churches, but all would allow contraceptive education. CONCLUSIONS: Many African-American churches are open to including sexuality education among their health education offerings for young adolescents. The church should be considered as a potential forum for providing comprehensive sexuality education for African-American adolescents.

Sexual asphyxia by hanging--a case report and a review of the literature.

A case of sexual asphyxial death by hanging is presented. A 35-year-old male, found dead lying on his face in a bed of a truck cab, had hanged himself from a window frame using a leather belt. He was completely naked. There were pornographic and sadomasochistic magazines beneath his face, opened to pages depicted nude photographs of a woman. Autopsy findings revealed a ligature mark on the neck and petechial hemorrhages in the conjunctivae, but there were no hemorrhages in the neck muscles or fractures of the hyoid bone or the thyroid cartilage. The alcohol levels in the blood and urine were 0.78 and 0.45 mg/ml, respectively. The circumstances suggested that his death was accidental, and due to asphyxia by hanging performed to enhance sexual gratification during masturbation. Sexual asphyxia is reviewed and discussed.

The associations among semen quality, oxidative DNA damage in human spermatozoa and concentrations of cadmium, lead and selenium in seminal plasma.

To explore the associations among semen quality, oxidative DNA damage in human spermatozoa and concentrations of cadmium, lead and selenium in seminal plasma, 56 non-smoking subjects were asked to collect semen by masturbation into a sterile wide-mouth metal-free plastic container after 3 days of abstinence. The conventional semen parameters were analysed. The concentrations of Cd, Pb and Se in seminal plasma were detected using atomic absorption spectrophotometer. 8-OHdG levels in sperm DNA were measured using HPLC-EC. The results showed that the geometric mean concentrations of Cd, Pb and Se were 0.78, 7.8 and 51.4 microg/l, respectively. The geometric mean of 8-OHdG/10(6) dG was 51.4 (95% CI: 21.5-123.0). A significant inverse correlation exists between Cd and sperm density (r=-0.28, P<0.05), and between Cd and sperm number per ejaculum (r=-0.27, P<0.05). In contrast, there was a significantly positive correlation between Se and sperm density (r=0.50, P<0.01), between Se and sperm number (r=0.49, P<0.01), between Se and sperm motility (r=0.40, P<0.01), and between Se and sperm viability (r=0.38, P<0.01). No statistically significant correlation was observed between Pb and semen quality. A significant inverse correlation was observed between 8-OHdG and sperm density (r=-0.34, P<0.01), between 8-OHdG and sperm number per ejaculum (r=-0.30, P<0.01), and 8-OHdG and sperm viability (r=-0.24, P<0.05). 8-OHdG was significantly correlated with Cd in seminal plasma (r=0.55, P<0.01). A significant but weak positive correlation was found between 8-OHdG and Pb concentration in seminal plasma (r=0.28, P<0.05). In contract, a significant inverse correlation was observed between 8-OHdG and Se concentration in seminal plasma (r=-0.40, P<0.01). The results indicate that Cd in seminal plasma could affect semen quality and oxidative DNA damage in human spermatozoa. Se could protect against oxidative DNA damage in human sperm cells. Pb did not appear to have any association with the semen quality when concentration of Pb in seminal plasma was below 10 microg/l.

Introduction to methods for collecting human gametes in assisted reproduction.

The first objective of IVF is the collection of oocytes and spermatozoa. This article reviews the methods of choice for each sex. Collecting oocytes involves laparoscopic puncture and ultrasonographic puncture via transabdominal/transvesical and periurethral/transvesical, transvaginal methods. Male gametes are collected by masturbation, or by aspirating spermatozoa from the epididymis or from the testicle. Sperm collections can be taken from patients with disorders of ejaculation. A brief review of each approach is presented, with a critical analysis of each method.

Sexual outcome after epilepsy surgery.

The aim of this study was to provide a description of patient-perceived sexual change after temporal lobe resection (TLR) and extratemporal resection (ETR). Fifty-eight TLR and sixteen ETR patients completed a semistructured interview and questionnaire assessing sexual change after epilepsy surgery. Five areas of sexual functioning were addressed: sexual drive, thoughts/fantasies, interest, masturbation, and activity. Each patient's perception of sexual changes relative to perceived levels of normal functioning was assessed. Characteristically, the onset of sexual change occurred in the first three postoperative months and persisted to the time of interview. A postoperative sexual change was significantly more likely to be reported by patients who had undergone TLR (64%) than ETR (25%). In the TLR group, sexual change was significantly more frequent following right-sided resections. Marked sexual change occurred more frequently in females than males. Postoperative sexual change is an important outcome feature after epilepsy surgery. The predisposition of TLR patients to postoperative change provides further evidence for a temporal lobe contribution to sexual function.

Sexual behaviours and contraception among university students in Turkey.

The aim of this study was to evaluate the sexual attitudes and behaviours of university students. An anonymous questionnaire was administered to 550 final-year university students aged 20-25 years in Izmir, Turkey. Male students opposed premarital sexual intercourse for both genders more than female students did. The frequency of sexual intercourse among male students (61.2%) was higher than that among female students (18.3%). The mean age of first sexual intercourse was lower among male than among female respondents. The rate of condom use at first sexual intercourse was 47.4%. The frequency of having two or more past sexual partners and masturbation was higher among males than females. It was found that there were culture-specific and gender-dependent differences in sexual attitudes and behaviours of the university students. These results may help in the planning of education and health policies in Turkey.

Rich and mad in Victorian England.

Clinical analyses of 19th century psychiatric practice have been limited by the paucity of available records. Using the richly detailed casebooks of Ticehurst House Asylum, it was possible to study over 600 admissions and assess them using the Research Diagnostic Criteria. Over 80% of cases conformed to recognizable psychiatric illness, mainly schizophrenia and manic-depressive psychosis. Movement disorder, often equivalent to tardive dyskinesia, was noted in nearly one-third of schizophrenics. Violence, masturbation and severe psychopathology were also common features. The implications of these findings in terms of treatment, diagnosis and the rise of the asylum are discussed.

The effect of single-dose oxytocin application on time to ejaculation and seminal parameters in men.

PURPOSE: To report the effect of a single dose of oxytocin on ejaculation time and seminal parameters. METHODS: The prospective randomized clinical study was performed at a private assisted reproduction technology center and included 103 consecutive healthy men (semen donors or husbands of IVF patients). Oxytocin (16 IU) were administered intranasally to 49 subjects, randomly assigned to the study group just before masturbation to ejaculation. The time needed for ejaculation as well as the semen parameters was recorded according to the WHO standards, and compared to the control group of 54 subjects with no prior oxytocin treatment. RESULTS: No significant difference was noted between the two groups concerning ejaculation time and semen parameters. CONCLUSIONS: Although the administration of oxytocin stimulates sexual behavior and performance in mammalian species, our data indicate that oxytocin has no detectable effect on ejaculation time and seminal parameters after intranasal application in normal, healthy men.
