Sexual responsiveness in diabetic women.

Sexual responsiveness in 82 Type 1 (insulin-dependent) diabetic women was compared with that of 47 normal control subjects, using an interview method for rating various aspects of sexual response, and attitude questionnaires. The diabetic women were questioned about symptoms of autonomic neuropathy, and cardiovascular autonomic nerve function tests were performed. There were differences between the two groups in the reports of vaginal lubrication, but in most other respects the groups were similar. The diabetic women were not less orgasmic, and reported significantly fewer unpleasant feelings during sexual intercourse. They saw themselves and their husbands as less 'potent' than did the normal subjects. The possible enhancing effect of diabetes on the marriage of some diabetic women possibly counteracted the relatively mild physiological deficits involved. There was very little difference in sexual response between women with and without symptomatic autonomic neuropathy.

The potential for oxytocin (OT) to prevent breast cancer: a hypothesis.

This hypothesis proposes that carcinogens in the breast are generated by the action of superoxide free radicals released when acinal gland distension, under the influence of unopposed prolactin, causes microvessel ischaemia. Inadequate nipple care in the at-risk years leads to ductal obstruction preventing the elimination of carcinogens from the breast. The regular production of oxytocin (OT) from nipple stimulation would cause contraction of the myoepithelial cells, relieving acinal gland distension and aiding the active elimination of carcinogenic fluid from the breast. Mechanical breast pump stimulation causes an increase in plasma OT levels in the luteal but not in the follicular phase of the menstrual cycle. OT production upon nipple stimulation in the luteal phase of premenopausal, non-lactating women may be protective against the high rates of mitotic breast cell division noted at this time via the potential to block the effect of oestrogen. The epidemiology of breast cancer suggests that lengthy lactation time is beneficial. Sexual activity in nulliparous women also protects and OT levels have been shown to rise with orgasm in women and in men. OT systems in the brain are intricately linked to oestrogen and progesterone levels, and it is possible that these hormones may modify the OT secretory response both centrally and through an effect on the sensitivity of the breast. OT production with nipple care and in sex and lactation, and the reduction in cycling ovarian hormones that occurs with pregnancy, may all be important preventative factors in the development of breast cancer both pre- and post-menopausally.

The lifetime prevalence of psychosexual dysfunction among 55 to 57-year-olds in Iceland.

In this study, the largest Nordic study of its kind, investigated psychosexual dysfunction among subjects aged 55-57 years. The cohort included 862 subjects of both sexes and all were interviewed using the Diagnostic Interview Schedule (DIS). Results showed that 122 subjects had a lifetime diagnosis of psychosexual dysfunction. The lifetime prevalence of psychosexual dysfunction was 14.4%; of inhibited sexual desire, 9.8%; of inhibited sexual excitement, 3.5%; of inhibited orgasm, 2.1%; and of functional dyspareunia, 1.3%. Of the subjects with psychosexual dysfunction, 73% were women. The frequency was highest in those who had never married. Separated subjects had rates intermediate between the married and the never-married. The majority (76%) of affected subjects had only one dysfunction. However, 57% of them had received another psychiatric diagnosis at some time. Subjects with psychosexual dysfunction were less frequently diagnosed as suffering from alcohol abuse and dependence and social phobia than subjects with no psychosexual dysfunction.

Heterosexual copulatory patterns in stumptail macaques (Macaca arctoides) and in other macaque species.

A comparison of the mating behavior patterns of several macaque species reveals that the mating behavior of Macaca arctoides exhibits several unique features. The laboratory groups of stumptail monkeys observed had exceptionally long single-mount copulations characterized by a large number of pelvic thrusts, a slow thrusting rate, and an unusually salient male orgasmic pattern (characterized by body rigidity followed by body spasms and a typical facial expression and vocalization). The frequency with which the copulation culminates in ejaculation is unusually high, and copulating stumptails generally manifest "tieing" in a genital lock after ejaculation.

Patrons of massage parlors: some facts and figures.

A survey of 183 patrons of a massage parlor in Illinois indicated that the typical customer is a 35-year-old married white male from out of town with 13 years of education who is employed in a lower- or middle-class job and goes to church on Sunday. He reports having had a variety of heterosexual experiences in the past, has come to the parlor because of lack of sexual partner at this particular time or because of curiosity, will come to orgasm during the genital massage, and will find it sexually satisfying. He is likely to have high self-esteem, consider himself personally and sexually adjusted, consider his value system liberal, and to be somewhat sympathetic to the goals of the women's rights movement.

An empirical investigation of experimentally induced masturbatory fantasies.

The nature and correlates of experimentally induced masturbatory fantasies were studied. Subjects were requested to construct a story using the film of either a male or a female masturbating to orgasm as the eliciting stimulus. Results indicated that there are many sex differences in masturbatory fantasies which are most likely a consequence of the differential ability of men and women to form a positive projective identification with the same-sex protagonist in a film of masturbation as well as a function of the variations in the process by which men and women assimilate masturbation into a larger set of social meanings. The findings also attest to the ability of sex guilt and negative attitudes toward masturbation to account for the variability in masturbatory fantasies in a theoretically consistent and reliable manner.

Intergenerational change in sex behavior: a belated look at Kinsey's males.

This article replicates for Kinsey's male sample the decade-of-birth analyses provided in the Kinsey "female volume." Five generations of male respondents are compared in terms of total frequency of sexual activity, and frequency and incidence of nine specific categories of sexual behavior. Inj general, unmarried males born after 1900 experienced more frequent sexual outlet than did nineteenth-century males. Additionally, the proportion of total outlet devoted to various specific activities varied by birth decade. Solitary masturbation rose somewhat spectacularly in significance with the passing decades, while nocturnal emissions and animal contacts declined. Orgasms provided by heterosexual activities increased slightly for the early twentieth-century generations, but then declined to a point below their nineteenth-century levels. Although homosexual contacts accounted for a constant percentage of total outlet for unmarried males over the five generations, more males in each succeeding generation were actively engaging in homosexual activity, at least on a casual basis. Similarly, although heterosexual contacts accounted for a smaller percentage of all activity among the unmarried in later generations, more of the later-born males had engaged in such activity at least once. For married males, on the other hand, frequency of total outlet was unaffected by generation. A large and stable proportion of this outlet was provided by marital coitus. Although more males in later generations had experienced extramarital contacts, such activities accounted for a small and resonably stable proportion of total outlet, when frquency of occurrence was considered. Masturbation gained in significance, while nocturnal emissions and homosexual contacts declined, and animal contacts among the married were almost nonexistent in all generations.

Alternative behavioral approaches to the treatment of homosexuality.

Radical changes in attitudes toward homosexuality in American society are integrated into a new perspective for the therapist confronted by a client who engages in homosexual behavior. The traditional mandatory attempt to eradicate homosexual behavior has been expanded into three options, any one of which may be pursued by the therapist at the client's request: (1) modification of homosexual in favor of heterosexual behavior, (2) enhancement of homosexual behavior, and (3) ignoring of homosexual behavior if it is functionally unrelated to the presenting symptoms. Therapists' negative attitudes toward clients who engage in homosexual behavior are such as to abrogate expanded options and may results in therapeutic efforts at modification of homosexual behavior in defiance of the client's expressed wishes. Contrary to current professional belief, careful analysis and the use of appropriate techniques such as systematic desensitization, orgasmic reconditioning, and training in heterosocial skills generally obviate the necessity for aversive procedures in those instances where homosexual behavior is to be modified in favor of heterosexual behavior. Three case histories are presented illustrating the use of each of the expanded options described above.

Enhanced sexual behavior in exercising men.

The effects of 9 months of aerobic exercise on aerobic work capacity (physical fitness), coronary heart disease risk factors, and sexuality were studied in 78 sedentary but healthy men (mean age, 48 years). The men exercised in supervised groups 60 min per day, 3.5 days per week on average. Peak sustained exercise intensity was targeted at 75-80% of maximum aerobic working capacity. A control group of 17 men (mean age, 44 years) participated in organized walking at a moderate pace 60 min per day, 4.1 days per week on average. Each subject maintained a daily diary of exercise, diet, smoking, and sexuality during the first and last months of the program. Beneficial effects of chronic, vigorous exercise on fitness and coronary heart disease risk factors were obtained in close agreement with prior studies. Analysis of diary entries revealed significantly greater sexuality enhancements in the exercise group (frequency of various intimate activities, reliability of adequate functioning during sex, percentage of satisfying orgasms, etc.). Moreover, the degree of sexuality enhancement among exercisers was correlated with the degree of their individual improvement in fitness.

A vaginal temperature registration system.

A radiotelemetric method for measurements of vaginal temperature in the home milieu is presented. Registrations from two subjects show that vaginal temperatures vary up to and about 1 degree C nighttime. Initially, on going to bed, vaginal temperature drops. A further distinct drop occurs with any kind of experienced sexual arousal, reaching a minimum when and if orgasm is achieved. At rest, vaginal temperature varies rather regularly and in concurrence with rectal temperature throughout the night. The initial temperature drop may be caused by decrease in blood flow, whether determined by metabolic or by postural factors. Temperature variations of the resting vagina may be concomitant with other circadian temperature rhythmic variations, while the temperature decrease during sexual arousal may be caused by vaginal wall edema and/or possibly by change of position of the uterus. The main point of the investigation is methodological: it is felt that the method can provide clinicians and researchers with a tool by which important vaginal physiologic events can be measured under somewhat more optimalized circumstances than those offered by the laboratory milieu.

Sexual activities, desire, and satisfaction in males pre- and post-spinal cord injury.

Thirty-eight spinal cord injured (SCI) males (median age = 26) completed an 80-item multiple choice questionnaire (median 37 months postinjury) which assessed sexual functioning pre- and post-spinal cord injury in four areas: (i) sexual activities and preferences, (ii) sexual abilities, (iii) sexual desire, arousal, and satisfaction, and, (iv) sexual adjustment. Frequency of sexual activity decreased following SCI with a reduction in intercourse and increased interest in alternative sexual activities. Of complete quadriplegic subjects 38% reported the ability to have an orgasm accompanied by ejaculation underscoring the need for physiological studies. Partner's desire for sex as perceived by the SCI individual was correlated with frequency of sex and numbers of sexual partners postinjury. Subject's perceptions of their own and partner's sexual desire decreased following SCI. Sexual satisfaction decreased postinjury and was positively correlated with both the patients' and their partners' interest in penile-vaginal intercourse. Of the subjects, 27% reported sexual adjustment difficulties and 74% relationship difficulties but only 22% received counseling. Results indicate the importance of the availability and desire of a sexual partner in the sexual activities and satisfaction of the SCI individual. SCI patient and staff sexual education and counseling continue to be strong needs.

Experimental studies of the etiology of genital exhibitionism.

Several studies are reported which examine the critical stimuli and responses as well as personality factors important in genital exhibitionism. Using penile volume measurement, sex history questionnaires, personality tests, and behavioral observations, it was found that (1) exhibitionists responded most to mature females and were comparable to normals in reactions to children and men; (2) while exhibitionists indicated narcissistic desires in exposing, in a laboratory study they did not differ from controls in reactions to exposing with various reactions of the female, from sexual arousal and admiration to fear and anger; (3) the only strong features distinguishing exhibitionists from controls and other sexually anomalous subjects were peeping associated with orgasm and outdoor solitary masturbation; (4) exhibitionists seemed to be less assertive and less feminine than controls, but results were weak and inconsistent; (5) exhibitionists and controls did not differ in separation and divorce or marital satisfaction; (6) blood testosterone and penile reactivity of exhibitionists were within normal limits. Overall, the results suggest that most major theories of genital exhibitionism are wanting. It is suggested that narcissism and pedophilia be examined further in connection with exhibitionism.

Age and sexual behavior of Japanese macaques (Macaca fuscata).

The sexual behavior of the Arashiyama West troop, a natural semi-free-ranging troop of Japanese macaques, was studied during the 1973-1974 and 1974-1975 breeding seasons. The troop was transported intact from Japan to its current location in South Texas. There they have been free to move about in a 42.2-hectare electric fence enclosure. This report describes the relationships among age, aging, and sexual behavior. Males beginning at the age of 2.5 years were observed to series-mount estrous females in the double foot clasp mount position. Mounting in series in the double foot position is the normal pattern for Japanese macaque males. The ejaculation of semen with concomitant body movements indicative of orgasm begins at age 4.5 years at the earliest and continues until death. Males 4.5 and 5.5 years of age, sexually mature in the physiological sense, were not consistently sexually mature in the behavioral sense. The oldest male displayed traits that appear analogous to traits observed in aging human males. Females begin to experience estrus at 3.5 years of age. However, like pubescent males, pubescent females display behavioral patterns of sexual immaturity. The oldest female of the troop has remained sexually active. The attainment of sexual maturity by adulthood can be viewed as a learned process leading to efficiency and prowess, followed in old age by sexual involution.

Psychosocial development of heterosexual, bisexual, and homosexual behavior.

Relationships with overt adult Kinsey Scale scores (K) indicate that early sexual experiences are most closely related to K, followed in order by gender related and familial variables. A developmental model emphasizing social learning is presented. Interviewees were 7669 American white males and females. Elevated K (more homosexual scores) was found for females who had few girl companions at age 10 and few male companions at 16, had learned to masturbate by being masturbated by a female, had intense prepubertal sexual contact with boys or men, found thought or sight of females, but not males, arousing by age 18, had homosexual contact by age 18, higher K at 17, and higher first-year homosexual behavior frequency. Elevated K (more homosexual scores) was found for males who reported poorer teenage relationships with their fathers, had more girl companions at age 10, fewer male companions at 10 and 16, avoided sports participation, learned of homosexuality by experience, learned to masturbate by being masturbated by a male, had intense prepubertal sexual contact with boys or men, had neither heterosexual contact nor petting to orgasm by age 18, found thought or sight of males, but not females, arousing by age 18, had homosexual contact by age 18, higher K at ages 16 and 17, and had higher first-year homosexual behavior frequency. Behavioral bisexuals, those scoring between 2.0 and 4.0 on the K scale on the basis of overt behavior (0.7% of females, 1.2% of males), reported more arousal to heterosexual stimuli than did exclusive heterosexuals.

Changes in personality scores among couples subsequent to sex therapy.

Changes in personality scores and self-perception of 92 couples through sex therapy are reported. The sample included 52 couples with female symptoms (orgasmic dysfunction and vaginismus) and 40 couples with male symptoms (erectile dysfunction and premature ejaculation), who all completed therapy. One-year follow-up showed significant changes indicating a general increase of emotional stability and a reduction of neurotic tendencies in both partners.

Effects of antihypertensive drugs atenolol and nifedipine on sexual function in older men: a placebo-controlled, crossover study.

Investigated the adverse sexual effects of two antihypertensive drugs, atenolol and slow-release nifedipine, in a placebo-controlled, randomized, crossover study. Subjects were 16 older men (mean age = 66.6 years, SEM = 1.4) with mild to moderate hypertension. Subjects completed daily self-reports on 13 measures of sexuality: frequency of desire, coitus, noncoital partner sex, masturbation, morning erections, spontaneous erections, orgasms in coitus and masturbation, firmness of morning, masturbatory and coital erections, and subjective pleasure in coitus and masturbation. Except for a significant decrease in masturbatory erectile firmness with nifedipine therapy, variables did not differ between the two drug treatments or between either drug and placebo. Although the sample was relatively small, small differences between treatment means suggest that these antihypertensive agents are fairly benign relative to sexual function in men.

Long-term follow-up of "sex change" in 13 male-to-female transsexuals.

Thirteen male-to-female transsexuals were investigated in an intensive interview study. The follow-up period varied between 6 and 25 years, with an average of 12 years. Surgical outcome was disappointing, and only one-third of the patients where a vaginal construction was carried out had a functioning vagina. The importance of patient cooperation postoperatively is pointed out and reasons for noncooperation are discussed. The generally held view of transsexuals as hypo- or asexual is questioned. In this study, one-third of the patients were very active sexually both before and after radical genital surgery. More than half of these castrated and estrogen-treated former males experienced orgasm, but only one-third were judged as having a fair or good sexual adjustment after sex reassignment. The possibility of unsuccessful surgical results must continue to be an important part of presurgery reality orientation both in doctors and patients. One striking finding is that overall sexual adjustment is often unchanged by genital surgery. Psychosocial adjustment showed a slight improvement after surgery. However, the majority of patients (eight) were judged to be unchanged. Repentance was chosen as the most crucial single outcome variable. One patient had officially requested reversal of sex change and another three were judged as repenting surgery in more indirect ways. Thus for a total of four individuals (30%), sex reassignment was considered retrospectively to be a mistake. Despite their returning to a male social role after surgery, however, two of the repenting patients were judged as fairly well adjusted from a psychosocial point of view.

An analysis of self-reported sexual behavior in a sample of normal males.

Ninety-eight presumably normal London men, age 20-35 and sexually active in a stable relationship, responded to an invitation at their work place to participate in a detailed sexuality interview. The interview was developed by a group of WHO collaborators to measure possible effects on sexual functioning resulting from various medical regimens (for example, a male contraceptive pill). It assessed frequency of coitus and masturbation during the previous 4 weeks, a variety of subjective ratings of sexual interest, satisfaction, and quality of relationships, as well as reports of the nature and incidence of various sexual problems. The study sample's responses displayed internal consistency and in general supported the inference that the sample was not atypical. The data appear to support Westoff's (1974) notion that the frequency of coitus has increased since the early normative reports by Kinsey et al. (1948). Most importantly, the results of principal components analyses point to the fact that overall sexual drive or "libido" (e.g., frequency of sexual behavior) is independent of several other possibly significant dimensions, including latency to orgasm, quality of sexual experience, autoeroticism, and the incidence of erectile difficulties. It is concluded that the sexuality interview provides potentially useful baseline data against which to evaluate effects of sexual therapy or drug regimens.
