Ovariotomy for menstrual madness and premenstrual syndrome--19th century history and lessons for current practice.

Ovariotomy--the removal of normal ovaries, known as Battey's Operation--began in 1872 and became the fashionable treatment of menstrual madness, neurasthenia, nymphomania, masturbation and "all cases of insanity". This practice was supported by distinguished gynecologists and psychiatrists, becoming one of the great medical scandals of the 19th century. In modern times, if menstrual madness is considered to be premenstrual dysphoric disorder (PMDD), and ovariotomy, the surgical equivalent of ovulation suppression of GnRH analogues, it can be argued that the surgery would have been effective for this limited indication, although the side effects of long-term estrogen deficiency would have made the treatment unacceptable. Currently, the successful hormonal treatment of PMDD is one of suppression of ovulation and removal of the cyclical hormonal changes in the luteal phase, probably progesterone, which is the essential cause of PMDD. Such therapy would be by GnRH analogues, transdermal estradiol and, in a few cases, the surgical option of hysterectomy and bilateral salpingo-oophorectomy with adequate hormone replacement. A study of medical history can help us prevent the mistakes of over-enthusiasm but positive lessons can be learned.

HIV serostatus disclosure among gay and bisexual men in four American cities: general patterns and relation to sexual practices.

The present study examined patterns of serostatus disclosure among previously untested HIV-seropositive and HIV-seronegative gay and bisexual men recruited from four American cities (n = 701). Six months after learning their HIV serostatus, 97% of study participants had disclosed their test results to at least one other individual. Consistent with earlier studies, test results were most frequently shared with friends and the respondent's primary partner. HIV serostatus was disclosed less frequently to family members, co-workers, and non-primary sex partners. Compared with HIV-seronegative men, HIV-seropositive men were more likely to have disclosed their status to a health care provider and less likely to have shared this information with family members. Of seropositive men, 11% did not disclose their serostatus to their primary partner and 66% did not disclose to a non-primary sex partner. Of HIV-seropositive men with one or more non-primary partners, 16% of those who did not disclose their serostatus reported inconsistent condom use during anal intercourse with these partners. No significant differences in self-reported sexual practices were observed for HIV-seropositive disclosers versus non-disclosers. Compared with HIV-seronegative men who did not disclose, seronegative men who shared information about their serostatus were more likely to have had receptive anal intercourse with their primary partner (p < 0.05) and to have engaged in mutual masturbation (p < 0.005), receptive oral sex (p < 0.005) and insertive anal intercourse (p < 0.05) with non-primary partners. No significant differences were observed between disclosers and non-disclosers with regard to condom use. Implications of the findings for future research and HIV prevention programmes are discussed.

Parallel accounts? Discrepancies between self-report (diary) and recall (questionnaire) measures of the same sexual behaviour.

Questionnaires and diaries have complementary biases and advantages for obtaining information on sexual behaviour but self-completed sexual diaries have the advantage of reducing retrospective bias. In a validation study of homosexual behaviour, sexual diary counts and subsequent questionnaire estimates (together with ratings of the certainty of the estimates) referring to the same month are compared and the discrepancies analyzed. Main findings include: questionnaire data yield consistently higher average estimates than diary counts, but have the same ordinal profile; individual difference (diary-questionnaire) scores show that 55% of questionnaire estimates of acts are higher than diary counts, 20% are identical and 25% are under-estimates; discrepancies are differentially located in different sexual acts. Masturbation and fellatio are systematically over-estimated in questionnaires and anal intercourse without a condom is the major source of inaccuracies, but in different directions: active partners under-estimate and passive partners over-estimate the amount of highest-risk sex. A strategy of joint use is discussed.

Sexuality in persons with lower extremity amputations.

PURPOSE: There is a paucity of information regarding sexual functioning in persons with lower extremity amputations. The purpose of this study was to describe sexual and psychological functioning and health status in persons with lower extremity amputation. METHODS: Self-report surveys assessed sexual functioning (Derogatis Inventory), depression (Beck Depression Inventory, anxiety (State-Trait Anxiety Inventory), and health status (Health Status Questionnaire) in a convenience sample of 30 men with lower extremity amputations. Mean age of the participants was 57 years (range 32-79). Mean duration since amputation was 23 months (range 3-634 months). Twenty one subjects (70%) had trans-tibial and seven subjects (23%) had trans-femoral amputations. RESULTS: A majority of subjects were experiencing problems in several domains of sexual functioning. Fifty three percent (n = 16) of the subjects were engaged in sexual intercourse or oral sex at least once a month. Twenty seven percent (n = 8) were masturbating at least once a month. Nineteen subjects (63%) reported orgasmic problems and 67% were experiencing erectile difficulties. Despite these problems, interest in sex was high in over 90% of the subjects. There was no evidence of increased prevalence of depression or anxiety in these subjects when compared to other outpatient adult populations. CONCLUSIONS: Sexual problems were common in the subjects studied. Despite these problems, interest in sex remained high. Few investigations have been directed toward identifying the psychological and social factors that may contribute to these problems and more research with a larger population is needed in this area.

Sexual attitudes and behaviors among medical students in Dokuz Eylul university, Turkey.

Gaining a healthy sexual attitude and behavior and being able to show appropriate approaches to patients in terms of sexual issues are important acquisitions for medical students. The aim of the present study was to determine, compare, and evaluate the sexual attitudes and behaviors of Dokuz Eylul University Faculty of Medicine students. An anonymous questionnaire was filled in by first- and sixth-year students in order to determine their sexual attitudes and behaviors. While information sources in the adolescence period for both genders were friends in the first place, these sources were mostly mothers, books, newspapers--magazines for females, and newspapers--magazines and television for males. The opinion of males about having sexual intercourse before marriage for males was positive, and females were more tolerant about males having this experience before marriage as compared to females having sexual experience before marriage. Rates of expression of having sexual intercourse and masturbation were found to be higher for male students. The first sexual experience with a sex worker or sentimentally insignificant partner was high among males. In general, the rate of condom use was lower, and the rate of coitus interruptus was found to be higher than in foreign studies. All the students declared 'my own will and values' as the most frequent factor affecting their sexual attitudes and behaviors, and high rates for 'social factors', 'religious requirements', 'the expectations of families', and 'protection from sexually transmitted diseases' were observed. The findings lead to the conclusions that gender differences exist in the sexual attitudes and behaviors of medical students; the enhancing effect of the traditional structure on gender discrimination is still continuing; students are not provided with sufficient scientific approach or training prior to the university education; and beyond biomedical training, they should receive more support in those fields during their medical education.

Concordance between women's physiological and subjective sexual arousal is associated with consistency of orgasm during intercourse but not other sexual behavior.

Many studies have found a discordance between women's genital (vaginal pulse amplitude) and subjective sexual arousal responses to erotica. We hypothesized that the association between the physiological and subjective domains would be greater for women with greater orgasmic consistency during penile-vaginal intercourse but not for orgasm consistency during other sexual behaviors. We confirmed this specific hypothesis in a sample (N = 38) of postmenopausal women. In addition, we discovered that the correlation between the domains was unrelated to social desirability responding, that orgasm consistency was not less for intercourse than for other sexual activity, and that orgasm consistency during intercourse was uncorrelated with orgasm consistency during masturbation. We discuss the results in terms of the unique nature of penile-vaginal intercourse, our study's implications for sex therapy, and orgasm consistency during intercourse being an operational measure of functional vaginal sensitivity and sexual pleasure integration and organization.

Transgender HIV prevention: implementation and evaluation of a workshop.

Virtually no HIV prevention education has specifically targeted the transgender community. To fill this void, a transgender HIV prevention workshop was developed, implemented and evaluated. A 4 h workshop, grounded in the Health Belief Model and the Eroticizing Safer Sex approach, combined lectures, videos, a panel, discussion, roleplay and exercises. Evaluation using a pre-, post- and follow-up test design showed an increase in knowledge and an initial increase in positive attitudes that diminished over time. Due to the small sample size (N = 59) and limited frequency of risk behavior, a significant decrease in unsafe sexual or needle practices could not be demonstrated. However, findings suggested an increase in safer sexual behaviors such as (mutual) masturbation. Peer support improved significantly. Future prevention education should make special efforts to target the more difficult-to-reach, high-risk subgroups of the transgender population.

The Sexual Health Model: application of a sexological approach to HIV prevention.

This article outlines the Sexual Health Model and its application to long-term HIV prevention through comprehensive, culturally specific, sexuality education. Derived from a sexological approach to education, the model defines 10 key components posited to be essential aspects of healthy human sexuality: talking about sex, culture and sexual identity, sexual anatomy and functioning, sexual health care and safer sex, challenges to sexual health, body image, masturbation and fantasy, positive sexuality, intimacy and relationships, and spirituality. A brief review of literature supporting a need for a more explicit focus on sexuality and relationships in HIV prevention is presented to demonstrate the relevance of the Sexual Health Model. The model in anchored in a holistic definition of sexual health. This definition is followed by a description of the Sexual Health Model's developmental origins in sexuality education, the importance of culturally relevant information, and the authors' qualitative and quantitative research. The model's 10 key components are discussed in more depth, and the theoretical and practical applications of this approach to HIV prevention are discussed. The article concludes with some cautions and suggestions for research. It is recommended that HIV prevention agencies contemplating use of the model should design their sexual health intervention to fit the unique needs of their target population. Evaluation of the effectiveness of interventions based on the model has begun, but further research is needed to confirm its viability.

In-vitro fertilization and intracytoplasmic sperm injection in the treatment of infertility after testicular cancer.

Treatment of testicular cancer (TC) may cause infertility due to reduced sperm quality with or without an ejaculation problem. In cases of anejaculation or retrograde ejaculation, spermatozoa can be obtained by transrectal electroejaculation (TE) or testicular sperm extraction (TESE) and used for in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). In this study, 15 out of 17 couples evaluated for infertility after TC, underwent a total of 21 treatment cycles, resulting in 18 embryo transfers. Spermatozoa were obtained by TE in 16 cycles, by masturbation in three cycles and by TESE in one. In one cycle no spermatozoa were found using TESE. Fertilization and cleavage was achieved by IVF in seven cycles and ICSI in 11 cycles; average fertilization rates of 57 and 55% respectively were observed. Twelve clinical pregnancies occurred, of which 11 have been delivered or are ongoing. The ongoing pregnancy rate was 57% per cycle. These results show that infertility after testicular cancer can be treated effectively with IVF and that ICSI even permits treatment of patients who have severe oligozoospermia.

Diurnal variation of semen quality in human males.

The possibility of a diurnal variation in semen quality was tested in 54 human males attending our infertility clinic. Of the enrolled subjects, 24 were normozoospermic and 30 were suffering from oligo- and/or asthenozoospermia. Seminal fluid was collected by masturbation twice by each subject, once in the morning (7:00-7:30 a.m.) and once in the afternoon (5:00-5:30 p.m.). Abstinence from sexual intercourse for 3-4 days before each of the two collections was requested. Semen parameters were evaluated independently by two biologists before and after pellet swim-up. Beside similar macroscopic parameters, specimens collected in the afternoon showed a higher number (P < 0.01) and concentration (P < 0.01) of spermatozoa. Also, immediately (P < 0.05), and at 1 h (P < 0.02) and 2 h (P < 0.01) after pellet swim-up, the number of spermatozoa with progressive linear motility was higher in the afternoon than in the morning. These data are the first documenting a diurnal rhythm in sperm quality which may contribute to the reported variability in semen parameters, and may prove useful for spontaneous and assisted conceptions.

Hepatocyte growth factor in human semen and its association with semen parameters.

Hepatocyte growth factor (HGF) is a structurally unique growth factor with potent motogenic (motility inducing) effects. Studies in the murine male genital tract have suggested important associations between HGF and the acquisition of sperm motility during epididymal maturation. The aim of this study was, therefore, to determine the concentration of HGF in human semen and assess its correlation, if any, with sperm motility and other semen parameters. Semen samples were collected by masturbation and analysed using standard procedures. HGF concentrations were measured in duplicate using an enzyme-linked immunoassay technique. Total protein estimations were also made in a subset of samples. The 95 subjects were divided into three groups for analysis: normozoospermic, subnormal semen and azoospermic. HGF was detected in all samples (median 0.456, 25th centile 0.388, 75th centile 0.556 ng/ml). No significant correlations were found between semen HGF concentrations and sperm concentration, motility, total sperm count or total motile count. There were no significant differences in mean HGF concentrations between the three subgroups. In conclusion HGF is present in human semen in significant quantities. The data do not suggest HGF concentrations are correlated with parameters of sperm motility.

The male IVF patient--psychosomatic considerations.

In order to study psychosomatic considerations of the male IVF patient, three issues were investigated. First, the personality traits of sterile males (n = 180) were recorded. Male IVF patients were found to have largely the same personality traits as the general population although they tended to have more dominant and retentive traits. Second, in examining the specific stress experiences during IVF, the individual treatment steps were ranked as being similarly stressful by both partners. Males felt the waiting periods (fertilization? pregnancy?) to be clearly more unpleasant than the physical aspects of treatment (e.g. masturbation). Third, an individual comparison of sperm parameters taken during the diagnostic phase with those measured during the IVF attempt, showed that density and morphology were significantly different. Some practical recommendations to reduce the stress that men experience during IVF include his presence during the treatment steps that the female must undergo, as well as his participation in a self-help discussion group.

Lack of effect of a single i.v. dose of oxytocin on sperm output in severely oligozoospermic men.

BACKGROUND: ICSI into the oocyte is the only treatment currently available for most male patients with severe oligozoospermia who wish to father children. In order to perform ICSI, motile sperm need to be recovered from the ejaculate and, if no sperm or not enough motile sperm are recovered on the day of ICSI, testicular sperm extraction (TESE) must be performed. Oxytocin stimulates epididymal contractility and may be important for the release of stored sperm. The aim of this randomized single-blind cross-over study was to establish the effects of oxytocin on sperm output in severely oligozoospermic men. METHODS: Forty-nine infertile men with sperm concentrations <0.2 x 10(6)/ml were studied on two occasions after 3-4 days of sexual abstinence. They received an i.v. injection of saline or oxytocin 0.75 IU in random order, and commenced masturbation within 5 min. Ejaculate analysis was performed according to the WHO 1999 guidelines. RESULTS: A single i.v. dose of oxytocin resulted in no change in ejaculate volume (P = 0.4), total sperm count (P = 0.14) or sperm motility (P = 0.9). There was no significant correlation between the change in total sperm count and FSH levels (r = -0.32, P = 0.2), or the change in total sperm count and estradiol levels (r = -0.02, P = 0.9). Similar results were found in a subgroup of men with total sperm counts of <100. CONCLUSIONS: Our data indicate that a single-dose of i.v. oxytocin has no detectable effect on seminal parameters in men with severe oligozoospermia.

"Where doctors differ": the debate on circumcision as a protection against syphilis, 1855-1914.

During the late nineteenth and early twentieth centuries there were two views on the relationship between syphilis and male circumcision: one was that circumcision provided protection against syphilis, another that circumcision was itself a significant source of syphilitic infection. This article reviews this debate, relates the first view to an influential article by Jonathan Hutchinson in 1855 and considers the subsequent use made of his statistics. It is suggested that the original statistics were of dubious value and that the promise of protection against syphilis was an additional argument for doctors who were keen to introduce universal circumcision of male infants for other reasons, the most significant of which was related to the conviction that it would discourage masturbation. The article further considers the controversy over whether Jews were healthier than other peoples, and the interaction among medical, moral, and customary/religious reasons for circumcising boys, and concludes that, while the operation never played any role in the control of syphilis, circumcision was indeed a significant cause of illness and death among male infants before the standardization of aseptic operating techniques.

Puberty in the male chimpanzee: progressive maturation of semen characteristics.

Cellular and biochemical characteristics of semen obtained by masturbation were studied in 5 pubertal chimpanzees during 1.5 yr. The dental age corresponding to the beginning of the pubertal testicular growth (Po) ranged from 5.0 to 8.3 years (mean = 6.7 +/- 1.2 yr). Time-related variations of all studied parameters were analyzed according to Po and, therefore, independently of the dental age. The emission of first ejaculates, and therefore the onset of activity of the accessory sex gland, was estimated to occur 4 mo after Po. The ejaculate volume (n = 132, r = 0.704, p less than 0.001), as well as the total amounts of l-carnitine (n = 65, r = 0.649, p less than 0.001), fructose (r = 0.522, p less than 0.001), citrate (r = 0.748, p less than 0.001), and acid phosphatase (r = 0.756, p less than 0.001) increased with time. First-obtained ejaculates contained no spermatozoa. Spermarche was estimated to occur 9.4 mo after Po. Total sperm count increased with time (r = 0.595, p less than 0.001). The motility and viability of spermatozoa increased with time (r = 0.474, p less than 0.01 and r = 0.632, p less than 0.001, respectively) while their morphology did not vary. The volume of the liquefied fraction and its content in free spermatozoa considered as available for fecundation remained low until the end of the study, most likely because of a delayed maturation of the prostate. This study shows that the maturation of the male genital tract is a progressive process. (ABSTRACT TRUNCATED AT 250 WORDS)

Effect of computer-assisted self-interviews on reporting of sexual HIV risk behaviours in a general population sample: a methodological experiment.

OBJECTIVES: To develop methods to maximize the accuracy of reporting HIV risk behaviours in a general population survey. We assessed the feasibility of using a computer-assisted self-completion interview (CASI) in comparison with pen-and-paper self-completion interview (PAPI). DESIGN: A probability sample survey of residents aged 16-44 years in Britain, with alternate assignment of addresses to interview by CASI (462) or PAPI (439). METHODS: Personal interviews exploring demographic and sexual behaviour variables. Principal outcome measures were the impact of CASI in relation to PAPI on data quality and rates of reporting a range of behaviours. RESULTS: A total of 901 interviews were completed; 829 individuals were eligible for and accepted the self-completion module. Internal consistency of data items was greater with CASI than PAPI and item non-response was lower. Overall, there was no significant difference in rates of reporting between CASI and PAPI. The main effect for CASI compared with PAPI in a generalized estimating equation (GEE) analysis was an OR (95% CI) of 1.04 (0.92-1.17). Variables were also examined individually, including homosexual partnership (adjusted OR 1.26 95%, CI 0.69-2.29), payment for sex (adjusted OR 0.68 95% CI 0.29-1.59), masturbation (adjusted OR 0.89 95% CI 0.66 1.22) and five or more partners in the past 5 years (OR 0.85 95% CI 0.61 -1.19). CONCLUSION: We found no evidence of a consistent effect of CASI on rates of reporting sexual HIV risk behaviours in this sample. CASI resulted in improvement in internal consistency and a reduction in missed questions.

Sexual behavior problems and psychopathology symptoms in sexually abused girls.

OBJECTIVE: This study contrasted a group of sexually abused girls, aged 6 to 12 years, with two demographically comparable control groups, girls from a child psychiatry outpatient department, and girls from a general pediatric clinic to determine whether differences in sexual behavior and psychopathology symptoms could be demonstrated. METHOD: All girls and their mothers underwent an evaluation protocol composed of two parent-report inventories, the Child Behavior Checklist and the Child Sexual Behavior Inventory. RESULTS: Sexually abused girls and psychiatric controls manifested more psychopathology symptoms, including internalizing and externalizing behaviors, than the nonpsychiatric controls. Relative to both control groups, sexually abused girls manifested more sexual behavior problems: masturbating openly and excessively, exposing their genitals, indiscriminately hugging and kissing strange adults and children, and attempting to insert objects into their genitals. Abuse by fathers or stepfathers involving intercourse was associated with particularly marked sexual behavior disturbances. There was a subgroup of sexually abused girls who tended to force sexual activities on siblings and peers. All of these girls had experienced prolonged sexual abuse (more than 2 years) involving physical force which was perpetrated by a parent. CONCLUSIONS: Findings suggest that sexual abuse in preadolescent girls is associated with sexual behavior problems.

Psychosexual dysfunction in males with genital anomalies: late adolescence, Tanner stages IV to VI.

OBJECTIVE: To assess psychosexual function in adolescent males with genital anomalies. METHOD: Fourteen consecutive males with bladder exstrophy-epispadias, 14 to 19 years old, Tanner stages IV to VI, were assessed along with their parents, using a developmental questionnaire, Hollingshead socioeconomic status rating, Child Behavior Checklist, Youth Self-Report, semistructured psychiatric interview, detailed sexual history, and 5 written, open-ended questions. RESULTS: All subjects showed psychosexual dysfunction in terms of genital satisfaction and genital touching; only 2 had ever undressed in front of anyone; only 2 had ever masturbated and only after age 16; 8 had few friends and only 5 considered any girls as friends; all expressed heterosexuality but only 4 had dated, 1 at age 17 and 2 after age 18; only the two 19-year-olds had experienced sexual intercourse, at the age of 19. All had an anxiety disorder. Half had experienced a major depressive disorder. CONCLUSIONS: Psychosexual dysfunction and anxiety were universal and chronic in these males with genital anomalies, leading to social and sexual developmental impairment. Half had a mood disorder. Implications for adulthood as well as for children with other genital anomalies are unclear but deserve further study. Males with genital anomalies should be evaluated for psychosexual developmental impairment.
