Some aspects of sexuality and reproduction in groups of captive marmosets (Callitbrix jacchus).

Several aspects of sexual and reproductive behaviour of Callithrix jacchus were studied for almost five years. The most important results are as follows: (1) In artificial groups (AG), heterosexual interactions were observed with varying frequencies between all group members; in the family groups (FG), however only between the parents (a-male and a-female). (2) In general, sexual interactions between two animals in the AG were tolerated by the other group members; in the FG, the offspring tried to disturb all copulations between the parents. (3) Pre- and postcopulatory play, and copulation with intromission and ejaculation are limited to the highest ranking group members. No difference was found between the highest and lower ranking males in the duration of copulation and number of pelvic thrusts. (4) The breeding privilege is correlated with rankorder; that is, only the most dominant male and female reproduce. This gives the impression of a monogamous relationship between the a-animals. (5) Independent of follicle maturation and ovulation, the a-females indicate estrous characterized by a considerable increase in willingness to copulate, associative behaviour between the a-male and the a-female (both most likely influenced or caused by pheromone activity), as well as aggressive behaviour between the a-female and the lower ranking females in the AG. Conflicts between the dominant and lower ranking group members, especially the females in AG, usually cause the group to split. The ability of the lower ranking females to reproduce is adversely affected by the stress to which they are subjected. (6) The parents of the FG are extremely tolerant of their sexually mature adult sons and daughters; expulsion of offspringe by the parents has not occurred as yet in the FG. (7) There is no certain evidence of cyclic visible changes of the genital region or menstrual bleeding in C. jacchus. (8) Captive C. jacchus females breed all year long; gestation is 144--146 days. (9) Homo- and autosexuality is reported for the males of the FG.

Severe impulsiveness as the primary manifestation of multiple sclerosis in a young female.

Severe impulsiveness in the absence of apparent neurological signs has rarely been reported as a clinical presentation of multiple sclerosis (MS). An 11-year-old female developed progressive and sustained personality disturbances including disinhibition, hypersexuality, drug abuse, aggressiveness and suicide attempts, without neurological signs. She was given several unsuccessful psychopharmacological and psychotherapeutic interventions. At age 21, a diagnosis of MS was made, confirmed by imaging, laboratory and neurophysiological studies. Although unusual, MS may produce pure neurobehavioral disturbances. In the present case, widespread demyelinization produced a complex behavioral disorder, with features compatible with orbitofrontal and Klüver-Bucy syndromes.

The effect on erection and orgasm of cystectomy, prostatectomy and vesiculectomy for cancer of the bladder: a clinical and electromyographic study.

Forty-three men who had been subjected to cystectomy and concomitant prostatectomy, vesiculectomy and urethrectomy were interviewed about their pre-operative and post-operative sexual activities at a mean of 3 (range 1 to 8) years after operation. Twenty-eight of the 38 men (74%) who had been sexually active continued to have some form of sexual activity, 21 of them achieving orgasm. Only 3 men had penile erection; 2 of them had been subjected to prostatectomy and 1 to prostatic resection. One of these men treated by prostatectomy had also had urethrectomy. Electromyographic registration from the striated external urethral sphincter, the bulbocavernosus muscle and the levator ani muscle showed normal duration of muscular contractions and length of interval between contractions after operation. The pattern of impulses during organs did not differ from that of normal men.

Unusual foreign bodies in the urethra and bladder.

We report 8 cases of self-inserted unusual foreign bodies in the lower urinary tract, all being treated from 1976 to 1990. Three of them were located in the urethra and 5 in the bladder. Several objects were found (electric cable, tweezers, hairpin, drawing pin, pebbles, paper clip). In 4 cases the objects were inserted for masturbatory purposes. Five of the patients were psychologically ill or handicapped. The most common reason for consultation was dysuria, and the treatment procedures were endoscopy in 5 patients and cystotomy in the other 3.

The effect of male circumcision on sexuality.

OBJECTIVE: To prospectively study, using a questionnaire, the sexuality of men circumcised as adults compared to uncircumcised men, and to compare their sex lives before and after circumcision. SUBJECTS AND METHODS: The study included 373 sexually active men, of whom 255 were circumcised and 118 were not. Of the 255 circumcised men, 138 had been sexually active before circumcision, and all were circumcised at >20 years of age. As the Brief Male Sexual Function Inventory does not specifically address the quality of sex life, questions were added to compare sexual and masturbatory pleasure before and after circumcision. RESULTS: There were no significant differences in sexual drive, erection, ejaculation, and ejaculation latency time between circumcised and uncircumcised men. Masturbatory pleasure decreased after circumcision in 48% of the respondents, while 8% reported increased pleasure. Masturbatory difficulty increased after circumcision in 63% of the respondents but was easier in 37%. About 6% answered that their sex lives improved, while 20% reported a worse sex life after circumcision. CONCLUSION: There was a decrease in masturbatory pleasure and sexual enjoyment after circumcision, indicating that adult circumcision adversely affects sexual function in many men, possibly because of complications of the surgery and a loss of nerve endings.

Female perversion: scenes and strategies in analysis and culture.

The author presents some ideas derived from observation in analysis about differing positions of Freud and Jung on perversion and about probable differences in perverse structural elements of women in contrast to men. In general perversion is understood as a defence of the self; in particular with women it is seen as a defensive way of achieving a false wholeness, a pseudo-androgyny. A case study describes the unfolding of a perverted transference. The importance of reaching the analyst and being understood by the analyst through projective identification is stressed. Quite often a sexually abusing mother seems to play an important role in generating female perversion; the implications in analysis are discussed as well as some ideas about culture and gender.

Cerebral vasospasm and headache during sexual intercourse and masturbatory orgasms.

BACKGROUND: The pathophysiology of the explosive type of headache associated with sexual activity is not completely understood. Five reported cases of patients with thunderclap headache, precipitated by sexual activity, in association with concomitant cerebral arterial narrowing, were found in the literature. METHODS: A 44-year-old woman with both coital and masturbatory headaches during orgasm associated with segmental reversible cerebral artery vasospasm was investigated. Cerebral anatomy and eventual spasm was documented by magnetic resonance imaging or digital angiography before, during, and after resolution of the orgasmic headache-vasospasm clinical manifestation. CONCLUSION: Findings of cerebral arterial narrowing, presented by some patients shortly after orgasmic headache attacks, support the hypothesis that segmental vasospasm may exert a role in the pathogenesis of this uncommon type of headache. The literature is reviewed, and possible mechanisms underlying the development of orgasmic headache are discussed.

On orgasm, sexual techniques, and erotic perceptions in 18- to 74-year-old Swedish women.

OBJECTIVES: To explore, in an age perspective, women's lifetime sexual techniques and the extent to which they had led to orgasm. To relate these techniques and current erotic perceptions to orgasmic function in women sexually active during the last 12 months and to describe the relative impact of orgasmic function/dysfunction on their sexual well-being. METHODS: A nationally representative sample of 18- to 74-year-old women (N = 1,335) participated. Nearly all were heterosexual. Current orgasmic capacity was broadly and subjectively classified into: no, mild, or manifest dysfunction. Sexual techniques and erotic perceptions were recorded together with level of sexual satisfaction. RESULTS: Generational differences characterized age at first orgasm and intercourse, types and width of sexual repertoire, and also current erotic perceptions, while orgasmic dysfunction and distress caused by it were less age dependent. Likely protectors of good orgasmic function, mainly against manifest dysfunction, were: a relatively early age at first orgasm, a relatively greater repertoire of techniques used--in particular having been caressed manually or orally by partner(s), achievement of orgasm by penile intravaginal movements, attaching importance to sexuality and being relatively easily sexually aroused. In turn, among other aspects of female sexual function women who did not have orgasmic dysfunction or distress were particularly likely to be satisfied with their sexual life. CONCLUSION: Besides providing data on matters frequently said to be sensitive this investigation shows that women's generation and with it several long-ranging aspects of women's sexual history and their feelings of being sexual are important indicators of their orgasmic and thereby their overall sexual well-being. When (in clinical practice) establishing treatment strategy for women with orgasmic dysfunction due respect should be given to these factors.

Persistent sexual arousal syndrome associated with increased soy intake.

INTRODUCTION: Persistent sexual arousal syndrome is an uncommon sexual complaint. Patients with this disorder can be distressed by the escalation of tension in the pelvic region and the prevailing necessity to diminish the pressure by self-stimulation. Patients frequently suffer from guilt or shame and often do not seek medical care. There are many potential causes of this disorder; however, a definitive etiology has yet to be elucidated. CASE: The patient is a 44-year-old female who presented to her gynecologist for evaluation of dysmenorrhea and menometrorrhagia. During the review of systems, the patient reported 5-6 months of increased pelvic tension, not associated with an increase in desire that required her to self-stimulate to orgasm approximately 15 times daily. Upon further inquiry, the patient disclosed that her dietary regimen included soy intake in excess of 4 pounds per day that began approximately 1 month prior to the onset of symptoms. RESULTS: Treatment consisted of supportive counseling and dietary modification. At the 3-month follow-up visit, the patient's menstrual difficulties and sexual complaints resolved. CONCLUSIONS: Although no known cause or cure of persistent sexual arousal syndrome has been identified to date, the success of reducing dietary of phytoestrogens in this patient may provide insight into the etiology of the disorder and suggest potential treatments.

Death from auto-erotic asphyxiation in a long-term psychiatric setting.

Death from auto-erotic asphyxiation is a startling phenomenon that is on the rise both in the general population and within psychiatric facilities. While these auto-erotic behaviors may lead to death, it is seldom the client's intention to do harm; rather, the intent is to heighten masturbatory sensations. After describing this phenomenon, the authors discuss implications for nursing care.
