Abstract
We report a 41-year-old woman with complex reflex epilepsy in which seizures were induced exclusively by the act of tooth brushing. All the attacks occurred with a specific sensation of sexual arousal and orgasm-like euphoria that were followed by a period of impairment of consciousness. Ictal EEG demonstrated two events of epileptic seizure that were provoked after tooth brushing for 38 and 14 seconds, respectively. The interictal EEG showed epileptiform discharges over the right anterior temporal region and interictal single photon emission computed tomography (SPECT) scan showed relative hypoperfusion in the uncus of right temporal lobe. Brain magnetic resonance imaging (MRI) revealed right hippocampal atrophy. We suggest that tooth-brushing epilepsy, especially with sexual ictal manifestations, may provide insight into the cerebral pathophysiology at the right temporolimbic structure.

Abstract
In this study, we analyzed heart rate variability during sexual activity using complex demodulation, which is a useful technique to study continuous changes in different frequency bands over short periods of time. Complex demodulation has the advantage of having higher time resolution compared to spectral analysis. We quantified the low frequency (LF: 0.04-0.15 Hz) and high frequency (HF: 0.15-0.5 Hz) amplitudes, and the LF/HF ratio before, during, and after the occurrence of orgasm. LF power is dually mediated by cardiac sympathetic and parasympathetic systems while HF power is mainly influenced by cardiac vagal function. We found a significant increase of cardiac sympathovagal interaction (LF/HF ratios) during the phase of orgasm. These findings are discussed in light of normal sexual physiology and the effect of sex on cardiac autonomic function in patients with heart disease, such as myocardial infarction.

Abstract
OBJECTIVE Sexual arousal and orgasm induce an increase in sympathetic activity as well as in catecholamine and prolactin plasma concentrations. However, the effects of sexual arousal and orgasm on immune functions in man are unknown. Thus, this study investigated the effects of masturbation-induced orgasm on lymphocyte circulation and cytokine production in healthy young males. METHODS In a crossover design, 11 volunteers completed an experimental condition in which they were asked to masturbate until orgasm and to participate in a control condition without sexual activity. Blood was drawn continuously for determination of endocrine parameters. In addition, leukocyte and lymphocyte subsets were analyzed via flow cytometry, and the production of lipopolysaccharide-induced interleukin 6 and tumor necrosis factor alpha was measured before and then 5 and 45 min after the orgasm. RESULTS The results confirmed transient increases in adrenaline and prolactin plasma concentrations. Sexual arousal and orgasm increased the absolute number of leukocytes, in particular natural killer cells (CD3-CD16+CD56+), in the peripheral blood. In contrast, T cell (CD3+) and B cell (CD3-CD20+) subpopulations as well as the production of interleukin 6 and tumor necrosins factor alpha remained unaffected by sexual activity. CONCLUSION These findings demonstrate that components of the innate immune system are activated by sexual arousal and orgasm.

Abstract
Sexual function draws on a complex network of peripheral and central neural pathways. The standard focus on erectile difficulties and peripheral therapies has been highly successful clinically but there are many unresolved issues in men and newly discussed issues in women that will likely benefit from improved understanding of the central nervous system and sexual function. The spectrum of future therapies, based on evolving central neurophysiological understanding, will include the management of problems related to orgasm, ejaculation, desire, motivation, anxiety, and pleasure. This new range of therapies will employ old and new neurochemicals and pathways singly or in combination. The capability of hormones to modulate many of the sexual pathways will also contribute to the rise of multiagent therapy. The expanded understanding, in combination with enhanced imaging technologies, will renew the role of diagnosis and cause-specific treatment.

Abstract
The neuroendocrine response to sexual activity in humans is characterized by a pronounced orgasm-dependent increase of plasma levels of prolactin. In contrast to the well-known inhibitory effects of chronic hyperprolactinemia on sexual drive and function, the impact of acute prolactin alterations on human sexual physiology is unknown. Therefore, this study was designed to investigate the effects of acute manipulation of plasma prolactin on sexual behavior. Ten healthy males participated in a single-blind, placebo-controlled, balanced cross-over design. Prolactin levels were pharmacologically increased to high levels (protirelin, 50 micro g i.v.) or reduced to low physiological concentrations (cabergoline, 0.5 mg p.o.). Sexual arousal and orgasm were then induced by an erotic film and masturbation. In addition to continuous neuroendocrine and cardiovascular recordings, the quality and intensity of the acute sexual drive, arousal, orgasm and refractory period were assessed by extensive psychometric measures. Administration of cabergoline decreased prolactin levels and significantly enhanced all parameters of sexual drive (P<0.05), function (P<0.01) and positive perception of the refractory period (P<0.01). Administration of protirelin increased prolactin concentrations and produced small, but not significant reductions of sexual parameters. The sexual effects observed from cabergoline were completely abrogated by coadministration of protirelin. Although different pharmacological sites of action of prolactin-altering drugs have to be considered, these data demonstrate that acute changes in prolactin plasma levels may be one factor modulating sexual drive and function. Therefore, besides a neuroendocrine reproductive reflex, a post-orgasmic prolactin increase may represent one factor modulating central nervous system centers controlling sexual drive and behavior. These findings may offer a new pharmacological approach for the treatment of sexual disorders.

Abstract
BACKGROUND Several pharmacotherapeutic approaches have confirmed the influence of neuroendocrine parameters on sexual desire, function, and fantasies in men; however, the relevance of acute neuroendocrine changes in mediating heightened sexual drive remains unknown. We recently demonstrated that plasma prolactin substantially increases following orgasm in healthy men, suggesting a feedback mechanism for peripheral prolactin in the control of acute sexual arousal. Because prolactin appears to play a regulatory role in acute sexual drive, we initiated this study to see whether sexual offenders with a high sexual drive have a different neuroendocrine response to sexual arousal. This study compares the prolactin response to orgasm of sexual offenders with high sexual drive and that of healthy subjects with average sexual drive. METHODS From a subject pool of 150 inpatients held because of sexual crimes, we recruited 10 volunteers, based on their high sexual drive according to an intensive, semistructured clinical interview. We defined sexual drive by a short refractory period and strong sexualization, or a high frequency of sexual stimulation. We analyzed the acute psychoneuroendocrine response to sexual arousal and orgasm continuously before, during, and after masturbation-induced orgasm in patients and control subjects. RESULTS Sexual offenders demonstrated higher sexual desire (P < 0.001) and function (P < 0.001) and a more positively perceived refractory period (P < 0.05). Both groups displayed a prolonged, significant increase in prolactin plasma levels after orgasm (P < 0.001). Sexual offenders did not differ from control subjects in neuroendocrine response to sexual arousal and orgasm. CONCLUSIONS These data demonstrate that sexual offenders with a high sexual drive do not differ from control subjects in the postorgasmic neuroendocrine response, particularly in prolactin release. This study confirms that factors other than peripheral hormones influence deviant sexual behaviour.

Abstract
OBJECTIVE To study psychosexual problems in men undergoing infertility evaluation. DESIGN A cohort observational study. SETTING Male infertility diagnostic center. PATIENT(S) Four hundred twelve men undergoing infertility evaluation between 1999 and 2001. INTERVENTION(S) Baseline and follow-up data on sexual functions. Semen analysis for samples collected by masturbation. A second analysis was requested in 2 weeks upon finding an abnormality of semen parameters. Penile vibratory stimulation to help men who failed to collect semen on their second or subsequent appointments. MAIN OUTCOME MEASURE(S) Sexual functions (erection and orgasm) during the time of infertility evaluation. RESULT(S) Seven of 412 men were excluded from the analysis due to a past history of sexual dysfunction. Of the remaining 405 men, 46 (11%) failed to collect semen by masturbation for a second semen analysis after repeated (2-4 times) attempts at 2- to 3-day intervals. Nine of these men (20%) were able to collect semen using vibratory stimulation. All 46 men experienced problems with erection or orgasm and had severe anxiety during attempts to masturbate and during sexual contact with their partners. CONCLUSION(S) Our study indicates that some men may experience sexual dysfunction of a psychogenic nature in response to the diagnosis of infertility.

Abstract
We have demonstrated that sexual activity produces transient sympathoadrenal activation and a pronounced, long-lasting increase in prolactin in men and women. However, by analyzing endocrine alterations at 10-min intervals, a precise assignment of these changes to the pre-, peri- and postorgasmic periods was not possible. Thus, the current study aimed to accurately differentiate the endocrine response to sexual arousal and orgasm in men using an automatic blood collection technique with 2-min sampling intervals. Blood was drawn continuously before, during and after orgasm over a total period of 40 min in 10 healthy subjects and were compared with samples obtained under a control condition. Sexual activity induced transient increases of plasma epinephrine and norepinephrine levels during orgasm with a rapid decline thereafter. In contrast, prolactin levels increased immediately after orgasm and remained elevated throughout the experiment. Although oxytocin was acutely increased after orgasm, these changes were not consistent and did not reach statistical significance. Vasopressin, LH, FSH and testosterone plasma concentrations remained unaltered during sexual arousal and orgasm. These data confirm that prolactin is secreted after orgasm and, compared with oxytocin, seems to represent a more reliable and sustained marker for orgasm in man. The results further reinforce a role for prolactin either as a neuroendocrine reproductive reflex or as a feedback mechanism modulating dopaminergic systems in the central nervous system that are responsible for appetitive behavior.

Abstract
This account describes studies from the Institute of Medical Physiology in the University of Copenhagen, starting in the mid 1970's, which included some of the earliest European laboratory investigations on human female genital function. The measurements involved vaginal pH, pO2, blood flow, motility, fluid and its ionic concentrations, amino-acid concentrations and electrical activity (transvaginal potential difference) usually in both the basal and sexual aroused states. The blood flow monitoring pioneered the use of the heated oxygen electrode. Other studies examined the effects of arousal to orgasm on cervical secretion, on the heart rate as an objective indicator of orgasmic excitement and investigated the actions of TRH and the cholinergic antagonist atropine on a number of vaginal parameters. The work was part of the scientific watershed that divided the previous descriptive era of human genital mechanisms from the now prevalent quantitative assessments.

Abstract
Chronic illness and its treatments can have a negative impact on sexual functioning. The mechanism of interference may be neurologic, vascular, endocrinologic, musculoskeletal, or psychologic. Patients may mistakenly perceive a medical prohibition to the resumption of sexual activity, or they may need advice on changes in sexual activity to allow satisfactory sexual functioning. Family physicians must be proactive in diagnosing and managing the alterations in sexual functioning that can occur with chronic illness. Patient education and reassurance are essential. Before sexual activity is resumed, patients with cardiovascular disease should be stratified according to risk. Patients with musculoskeletal disease should be educated about positional changes that may improve comfort during sexual activity. Psychosocial concerns should be addressed in patients with human immunodeficiency virus infection or acquired immunodeficiency syndrome. In patients with cancer, it is important to discuss sexual problems that may arise because of negative body image and the effects of chemotherapy. Patients who have disabilities can benefit from the use of muscle relaxants, technical adaptations, and expansion of their sexual repertoire.

Abstract
The effect of hysterectomy on sexual function is an issue of debate. There are reasons to believe that removal of the uterus can have adverse effects on female sexual functioning by disrupting the anatomical relations in the pelvis. In this article, we review the literature on the impact of hysterectomy (without oophorectomy and for benign conditions) on the sexual functioning of premenopausal women. There is evidence that women for whom there is a clinical indication for hysterectomy are often experiencing a decreased quality of life. After successful treatment of dysfunctional uterine bleeding, either by hysterectomy or uterus-saving alternatives, the majority of women report experiencing improved sexual functioning. Nonetheless, the research on the effect of hysterectomy on female sexual functioning is not conclusive. Prehysterectomy sexual functioning and psychosocial state are significant predictors for posthysterectomy sexual dysfunction and depression. A minority of women report developing sexual dysfunctions as a result of hysterectomy. The nature and extent of these dysfunctions have not been adequately investigated. Many investigations in this area are flawed by methodological imperfections. For example, qualitative changes in sexual functioning and changes in the physiology of sexual function often were not adequately addressed. In the future, researchers should include both objective measures of physiological functioning and use standardized and validated self-report questionnaires. A critical attitude towards the indications of hysterectomy remains mandatory.

Abstract
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.

Abstract
A spinal cord lesion (SCL) changes most functions below the level of lesion, including sexual function. Most women had sexual intercourse after the lesion, but describe practical problems. Many of them are capable of achieving organism, and are normally fertile. During pregnancy there is an increased risk of urinary tract infection. Delivery can take place vaginally. In the case of lack of progression or severe autonomic dysreflexia, cesarean section may be necessary. For erectile dysfunction in men with SCL, oral sildenafil may be used, alternatively intracavernous injection with prostaglandin E1. To obtain ejaculation penile vibratory stimulation (PVS) is used, and if this fails then electroejaculation. Impaired sperm quality with low motility is observed. Vaginal insemination at home with sperm obtained by PVS is possible. The fertility potential may be enhanced with assisted reproduction techniques, like intrauterine insemination and in vitro fertilisation.

Abstract
Changes induced by human sexual arousal serve reproductive and recreational functions. The current sexual phase model (desire, excitation, orgasm, and resolution) conveys little about this duarchy. Lack of spontaneous sexual desire in a third of nonclinic females indicates that the D phase needs splitting into D1 (the spontaneous [endogenous] activation of desire) and D2 (desire activated by sexual excitation at and during the E phase). Attempts to link D1 with reproduction by studies monitoring it over the menstrual cycle revealed a D1 peak just before or at ovulation, but its reliability is criticized because of the poor identification of the time of ovulation. Sexual arousal initiates enhanced genital blood flow, leading to the formation of a neurogenic transudate, lubricating the vagina, partly buffering its acidity, and increasing its oxygen tension all features that enhance spermatozoal function and survival. Orgasm occurs with vaginal and uterine contractions. The latter have been misinterpreted as powering rapid sperm transport to facilitate fertilization, but such fast transport would lead to the tubal deposition of noncapacitated, incompetent spermatozoa. Vagino-cervico elevation, however, delays rapid sperm transport and allows the initiation of decoagulation and sperm capacitation before the elevation resolves. The fastest transport of spermatozoa from cervix to the fallopian tubes occurs in the nonaroused female by uterine/subendometrial smooth muscle peristalsis. There is some evidence that even this may be reduced for a time after coitus, adding to the transport delay. If a number of the changes induced by sexual arousal are inadequately expressed, sexual as well as reproductive dysfunctions could arise.

Abstract
BACKGROUND Social phobia is a type of performance and interpersonal anxiety disorder and as such may be associated with sexual dysfunction and avoidance. The aim of the present study was to evaluate sexual function and behavior in patients with social phobia compared with mentally healthy subjects. METHOD Eighty subjects participated in the study: 40 consecutive, drug-free outpatients with social phobia (DSM-IV) attending an anxiety disorders clinic between November 1997 and April 1999 and 40 mentally normal controls. The Structured Clinical Interview for DSM-IV Axis I Disorders and the Liebowitz Social Anxiety Scale were used to quantitatively and qualitatively assess sexual function and behavior. RESULTS Men with social phobia reported mainly moderate impairment in arousal, orgasm, sexual enjoyment, and subjective satisfaction domains. Women with social phobia reported severe impairment in desire, arousal, sexual activity, and subjective satisfaction. In addition, compared with controls, men with social phobia reported significantly more frequent paid sex (p < .05), and women with social phobia reported a significant paucity of sexual partners (p < .05). CONCLUSION Patients with social phobia exhibit a wide range of sexual dysfunctions. Men have mainly performance problems, and women have a more pervasive disorder. Patients of both genders show difficulties in sexual interaction. It is important that clinicians be aware of this aspect of social phobia and initiate open discussions of sexual problems with patients.

Abstract
OBJECTIVE Improved selection criteria have lead to an increasing number of nerve-sparing radical retropubic prostatectomies (RRP) in patients with clinically localised prostate cancer (PCA). Patient questionnaire based outcome analysis on post-operative erectile function after uni- or bilateral nerve-sparing RRP is described. METHODS Between January 1992 and March 1999, 366 patients (mean age 62.5 years) underwent uni- or bilateral nerve-sparing RRP at our institution. Indication for nerve-sparing procedure was based on the results of a multivariate classification and regression tree analysis (CART). For evaluation of post-operative patient-reported rates of sexual and erectile function non-validated and validated questionnaires (IIEF 5) were administered after a follow-up of 12 months. Data of five operation periods were analysed. RESULTS The unilateral procedure resulted in rates of 13-29% of erections sufficient for unassisted intercourse. Some degree of tumescence was reported by 37-73% of the remaining patients. Bilateral nerve-sparing procedures were almost exclusively performed in periods 3-5, only four patients of period 2 received the bilateral procedure. Here, rates of erections sufficient for intercourse were 25% (period 2), 61% (period 3), 50% (period 4), and 52% (period 5), respectively. Patients with grades 4 and 5 erections had IIEF scores of 19.2 and 20.2 and patients without rigidity or tumescence had scores of 5.7 and 7.0 after uni- and bilateral nerve-sparing procedure, respectively. Patients <60 years of age had better erections than those > or =60 (unilateral: 19% versus 13%, bilateral 45% versus 38%). CONCLUSION Compared to a unilateral nerve-sparing procedure, the bilateral nerve-sparing technique revealed much better results inasmuch as about 50% of the patients reported recovery of erections sufficient for sexual intercourse without use of sexual aids.

Abstract
OBJECTIVE The purpose of the study was to determine if sexual behaviors, orgasm, tampon use, and douching during menstruation modify the risk of endometriosis. METHODS A case-control study was conducted. Subjects (n = 2,012) consisted of members of the Endometriosis Association and friends not affiliated with the organization who completed mailed surveys. Data were analyzed using chi(2), Fisher's exact test, t test, and regression analyses. RESULTS There was no difference between study groups concerning douching practices. However, cases were less likely than controls to report sometimes or often engaging in sexual behaviors during menstruation (p = 0.002, OR = 1.5), and sexual behaviors during menstruation that included orgasm (p = 0.001, OR = 1.5). Cases were also less likely than controls to report using only tampons (p < 0.0001, OR = 2.6). CONCLUSION Sexual activity, orgasm, and tampon use during menstruation may confer protection against endometriosis.

Abstract
The characteristics common to all human orgasm experiences and potential gender and contextual factors affecting these experiences were investigated in two studies. A two-dimensional descriptive model of the orgasm experience was evaluated by testing hypotheses concerning (a) fit of the model to adjective-ratings data describing male and female orgasm experiences, and (b) sexual context effects on the importance of model components. In the first model-evaluation study, 888 university students (523 women) provided adjective ratings to convey orgasm experiences attained through both solitary masturbation and sex with a partner. In a cross-validation study, 798 university students (503 women) provided similar ratings to convey orgasm experiences attained either through solitary masturbation or through sex with a partner. Overall, findings supported the utility of a two-dimensional model of the orgasm experience, an adjective-rating approach in comparing male and female orgasm, and the importance of examining sexual context effects on the orgasm experience.

Abstract
OBJECTIVE To review the psychology and physiology of female sexual dysfunction (FSD) and explore current strategies for prevention and treatment. DATA SOURCES Articles identified through a MEDLINE search using the term female sexual dysfunction. Additional references were identified from the bibliographies of retrieved articles. STUDY SELECTION Investigational studies, clinical trials, and review articles examining female sexual dysfunction. DATA SYNTHESIS FSD is a widespread problem that can arise from disorders of any component of female sexual response. These disorders are classified as problems with sexual desire, arousal, orgasm, and sexual pain. The dysfunction that characterizes these disorders may stem from a variety of factors, including psychologic issues surrounding sex and the effects of medications on female sexual response. Although pharmacists are unlikely to be involved in counseling patients about the psychologic aspects of sexual dysfunction, they can play a vital role in screening for and managing sexual adverse effects of medications. A variety of nonprescription, prescription, and investigational products may be of benefit for addressing the various types of disorders. CONCLUSION Pharmacists who have a thorough understanding of female sexual response, potential causes of dysfunction, and accepted treatment strategies can help detect FSD and advise women about their options for managing this common problem.

Abstract
OBJECTIVES To assess the changes in sex hormone levels with age and the relationship of sexual functioning to testosterone levels, evaluating serum testosterone levels and erectile function in men with lower urinary tract symptoms (LUTS). PATIENTS AND METHODS The study included 213 men with LUTS (age range 31-78 years) who had no confirmed erectile dysfunction. Their serum total and free testosterone, and sex-hormone binding globulin (SHBG) levels were measured, and they completed the International Index of Erectile Function (IIEF) questionnaire. RESULTS The total and free testosterone levels decreased and SHBG increased with age, but only the change in free testosterone and SHBG were statistically significant. The correlation with age was closer for free testosterone (r = - 0.356, P < 0.001) than for SHBG (r = 0.177, P = 0.010). Regression analysis of the five domain scores of the IIEF and three hormonal levels, after correcting for age, showed that free testosterone level was significantly correlated with erectile function (r = 0.2136, P = 0.005) and orgasmic function (r = 0.179, P = 0.020), but SHBG levels were significantly correlated only with orgasmic function (r = - 0.154, P = 0.046). Total testosterone levels showed no significant correlation with any of the five domains of the IIEF. CONCLUSIONS Of the sex hormone levels, the change in free testosterone correlated most closely with ageing and had the closest correlation with sexual activity. Contrary to previous reports, free testosterone and SHBG levels were significantly correlated with orgasmic function and/or erectile function rather than sexual desire. A complete study of sex hormone levels is needed to evaluate patients with erectile dysfunction.

Abstract
Orgasm itself, along with its specific psychodynamic, has stimulated few reflections and little research in the psychoanalytical field to date. In this regard, perspectives relating to orgasm are generally placed within a wider context covering desire, arousal and, of course, satisfaction. Freud himself seemed to show no particular or systematic interest in an orgasmic psychodynamic per se. This article, the aim of which is to consider the specific nature of orgasm, proposes a two-stage reflection. First, it considers the specific aspects of orgasm in order to arrive at a phenomenology of the orgasm itself--within a clearly defined framework. Second, it explains this phenomenology from a psychoanalytical point of view. These reflections lead us to suggest that while the erogenous zones in men and women respectively are at the root of the sexual arousal that leads to orgasm, it is most probably in fantasy that the female orgasm finds its major trigger. This is all the more relevant given that the existence of a real qualitative difference between clitoral and vaginal orgasm is now being challenged. This would tend to confirm the idea of a predominance of fantasy over bodily location, given that, quite clearly, it is not possible to attribute the former role to a precise area of the body. In this respect, only the analytical process is able to lead us to the primary sources of orgasmic problems--both male and female--and, above all, to reconstruct the origin of a satisfactory or unsatisfactory orgasm.

Abstract
In several studies we have recently demonstrated that orgasm induces prolactin secretion in healthy males and females. This suggests that prolactin may form a feedback regulator of the refractory period following orgasm. To examine this position we investigated the prolactin response of a healthy multi-orgasmic male subject. Blood was drawn continuously during masturbation-induced orgasm. The prolactin response of the case-subject was compared with that of nine healthy adult men with a normal refractory period. The case-subject showed no prolactin response to three orgasms. Data from this multi-orgasmic subject support the hypothesized role of plasma prolactin in contributing to sexual-satiation mechanisms.

Abstract
OBJECTIVE The aim of this study was to determine the effect of the Eros-Clitoral Therapy Device (Eros-CTD) on the sexual function of women with and without symptoms of female sexual arousal disorder (FSAD). DESIGN Periodic survey of sexual function in women using the Eros-CTD over a six-week period. SUBJECTS A total of 19 women participated in the study--10 with symptoms of FSAD and nine without symptoms of FSAD--ranging in age from 28 to 65 years, with a mean age of 45.2 years. METHODS Ten patients with symptoms of FSAD and 10 without symptoms were instructed in the use of the small, portable vacuum device, Eros-CTD. One woman without symptoms of FSAD withdrew early in the study for personal reasons. The patients were instructed in the correct use of the device and were asked to complete one Female Intervention Efficacy Index (FIEI) each week. The patients also kept diaries of their use of the device, noting the frequency, length, and strength of vacuum. RESULTS There was a significant improvement in all symptoms of FSAD (P < .05), including increased sensation, improved vaginal lubrication, enhanced ability to orgasm, and greater overall satisfaction. Patients without FSAD also reported similar changes in sensation, lubrication, ability to orgasm, and overall satisfaction. LIMITATIONS This study was done on a small sample of self-selected patients, was of limited duration, and had no long-term follow-up. All of these factors should be considered in interpreting the data. CONCLUSION The Eros-CTD was safe and effective in improving symptoms of FSAD in this group of women. Further studies on the efficacy of the Eros-CTD are indicated.

Abstract
Our recent research provides evidence that women with complete spinal cord injury (SCI) at the midthoracic level show perceptual responses to vaginal and/or cervical self-stimulation (for example, pain suppression and sexual response, including orgasm). On the basis of studies in laboratory rats, we hypothesized that the vagus nerves provide a sensory pathway from the vagina, cervix, and uterus directly to the brain in women. To test this hypothesis, we performed a PET-MRI study on two women with complete SCI and 1 woman with no injuries. Whereas control foot stimulation of the women with SCI did not activate the somatosensory thalamus, cervical self-stimulation increased activity in the region of the nucleus of the solitary tract, which is the brainstem nucleus to which the vagus nerves project. These preliminary findings suggest that the vagus nerves can convey genital sensory input directly to the brain in women, completely bypassing SCI at any level.

Abstract
Recent studies from our laboratory have investigated the hormonal response to various forms of sexual stimulation, including film, masturbation, and coitus in both men and women. This series of studies clearly demonstrated that plasma prolactin (PRL) concentrations are substantially increased for over 1h following orgasm (masturbation and coitus conditions) in both men and women, but unchanged following sexual arousal without orgasm. Here we discuss evidence suggesting that the PRL response to orgasm may play an important role in the control of acute sexual arousal following orgasm. Supporting this position, chronic elevations of PRL (hyperprolactinemia) produce pronounced reductions in animal sexual activity, and significant reduction of libido and gonadal function in both men and women. These data suggest that PRL may represent a peripheral regulatory factor for reproductive function, and/or a feedback mechanism that signals CNS centres controlling sexual arousal and behaviour. Thus, we propose a theoretical model of the role of PRL as a neuroendocrine reproductive reflex.

Abstract
This current study examined the effect of a 3-week period of sexual abstinence on the neuroendocrine response to masturbation-induced orgasm. Hormonal and cardiovascular parameters were examined in ten healthy adult men during sexual arousal and masturbation-induced orgasm. Blood was drawn continuously and cardiovascular parameters were constantly monitored. This procedure was conducted for each participant twice, both before and after a 3-week period of sexual abstinence. Plasma was subsequently analysed for concentrations of adrenaline, noradrenaline, cortisol, prolactin, luteinizing hormone and testosterone concentrations. Orgasm increased blood pressure, heart rate, plasma catecholamines and prolactin. These effects were observed both before and after sexual abstinence. In contrast, although plasma testosterone was unaltered by orgasm, higher testosterone concentrations were observed following the period of abstinence. These data demonstrate that acute abstinence does not change the neuroendocrine response to orgasm but does produce elevated levels of testosterone in males.

Abstract
Although Female Sexual Dysfunction (FSD) affects 40% of American women, there is no FDA-approved pharmaceutical therapy. The EROS-CTD (Clitoral Therapy Device, UroMetrics, Inc., St. Paul, MN) treatment is the first FDA cleared-to-market therapy for FSD. Clitoral engorgement is believed to play an important role in female sexual arousal and overall sexual satisfaction. The EROS-CTD is a small, battery-powered device designed to enhance clitoral engorgement, increase blood flow to the clitoris, and ultimately improve arousal in women with FSD. The objective of this study was to assess the effectiveness of the EROS-CTD on sexual arousal (genital sensation, vaginal lubrication, ability to reach orgasm, and sexual satisfaction) in normal volunteers and women with FSD.

Abstract
This critical review presents a synthesis of the available theoretical and empirical literatures on human orgasm. Findings from both normal and clinical human populations are included. Two major trends in the literature, the dichotomization of biological and psychological perspectives and the assumption of gender differences, are highlighted. A new multidimensional model of the psychological experience of orgasm is described with a view to futhering a biopsychological approach applicable to both sexes. Clinical applications of this new model are discussed.

Abstract
OBJECTIVE Our goal was to evaluate the relationship between obstetric perineal trauma and postpartum sexual functioning. STUDY DESIGN Our study was carried out with a retrospective cohort design in 3 groups of primiparous women after vaginal birth: Group 1 (n = 211) had an intact perineum or first-degree perineal tear; group 2 (n = 336) had second-degree perineal trauma; group 3 (n = 68) had third- or fourth-degree perineal trauma. These sample sizes reflect a 70% response rate. Outcomes were time to resuming sexual intercourse, dyspareunia, sexual satisfaction, sexual sensation, and likelihood of achieving orgasm. RESULTS At 6 months post partum about one quarter of all primiparous women reported lessened sexual sensation, worsened sexual satisfaction, and less ability to achieve orgasm, as compared with these parameters before they gave birth. At 3 and 6 months post partum 41% and 22%, respectively, reported dyspareunia. Relative to women with an intact perineum, women with second-degree perineal trauma were 80% more likely (95% confidence interval, 1.2--2.8) and those with third- or fourth-degree perineal trauma were 270% more likely (95% confidence interval, 1.7--7.7) to report dyspareunia at 3 months post partum. At 6 months post partum, the use of vacuum extraction or forceps was significantly associated with dyspareunia (odds ratio, 2.5; 95% confidence interval, 1.3--4.8), and women who breast-fed were > or = 4 times as likely to report dyspareunia as those who did not breast-feed (odds ratio, 4.4; 95% confidence interval, 2.7--7.0). Episiotomy conferred the same profile of sexual outcomes as did spontaneous perineal lacerations. CONCLUSIONS Women whose infants were delivered over an intact perineum reported the best outcomes overall, whereas perineal trauma and the use of obstetric instrumentation were factors related to the frequency or severity of postpartum dyspareunia, indicating that it is important to minimize the extent of perineal damage incurred during childbirth.

Abstract
Sexual disorders are common in women; however, the neurological basis of female sexual response has not been adequately investigated. This information is necessary to characterize the impact of various neurological disorders on sexual arousal in women and to develop appropriate management strategies for sexual dysfunction. To assess the spinal mediation of sexually stimulated genital vasocongestion in women, we conducted two laboratory-based, controlled analyses: (1) of women's genital, subjective, and autonomic responses to audiovisual erotic and audiovisual erotic combined with manual genital stimulation; and (2) of women's ability to achieve orgasm. Subjects included 68 premenopausal women with spinal cord injuries (SCIs) and 21 able-bodied, age-matched controls. Results indicated that preservation of sensory function in the T11-L2 dermatomes is associated with psychogenically mediated genital vasocongestion. Less than 50% of women with SCIs were able to achieve orgasm, compared with 100% of able-bodied women (p = 0.001). Only 17% of women with complete lower motor neuron dysfunction affecting the S2-S5 spinal segments were able to achieve orgasm, compared with 59% of women with other levels and degrees of SCIs (p = 0.048). Time to orgasm was significantly increased in women with SCIs compared with able-bodied controls (p = 0.049). Independent raters were unable to differentiate between subjective descriptions of orgasm from SCI women compared with controls. This information should be used when counseling women with spinal dysfunction about their sexual potential.

Abstract
Oxytocin is clearly involved in human reproduction and serves an important role in sexual arousal. Oxytocin serum levels were measured before and after sexual stimulation in 12 healthy women. Values of oxytocin 1 min after orgasm were significantly higher (p < 0.05) than baseline levels. This finding supports the hypothesis that oxytocin plays a major part in human sexual response both in neuroendocrine function and postcoital behavior.
