Brunet JF. Gaskell, Langley, and the "para-sympathetic" idea. eLife 2025; 14:e104826.

Abstract
Historically, the creation of the parasympathetic division of the autonomic nervous system of the vertebrates is inextricably linked to the unification of the cranial and sacral autonomic outflows. There is an intriguing disproportion between the entrenchment of the notion of a 'cranio-sacral' pathway, which informs every textbook schematic of the autonomic nervous system since the early XXth century, and the wobbliness of its two roots: an anatomical detail overinterpreted by Walter Holbrook Gaskell (the 'gap' between the lumbar and sacral outflows), on which John Newport Langley grafted a piece of physiology (a supposed antagonism of these two outflows on external genitals), repeatedly questioned since, to little avail. I retrace the birth of a flawed scientific concept (the cranio-sacral outflow) and the way in which it ossified instead of dissipated. Then, I suggest that the critique of the 'cranio-sacral outflow' invites, in turn, a radical deconstruction of the very notion of a 'parasympathetic' outflow, and a more realistic description of the autonomic nervous system.

Abstract
Prostate biopsy is the cornerstone in the diagnostic pathway of prostate cancer. It's normally performed using local or general anesthesia. The prostate's high sensitivity to mechanical stimuli and irritation is due to its complex nerve supply, mainly from the pelvic plexus. It originates from the sacral plexus, with both parasympathetic and sympathetic nerves having a role in prostatic innervation. As the procedure involves needle penetration into sensitive tissues, it is essential to ensure effective peribioptic pain management, as patients may experience considerable discomfort during the process. Local anesthesia has proven to be one of the safest, most reliable, and most effective approaches to managing this pain, as it provides targeted relief with minimal side effects. This report describes in detail the current anesthesia techniques applied during both transrectal and transperineal prostate biopsy procedures, delving into their mechanisms of action, as well as reviewing recent research findings on their efficacy. We describe an image-based step-by-step technique with dedication to pelvic anatomy for a comprehensive understanding of how local anesthesia can be administered and therefore enhance the overall experience of patients undergoing prostate biopsy.

Abstract
Adaptogens, comprising plants and mushrooms, modulate the immune system, energy balance, and various physiological processes, including reproduction. Despite their potential benefits, the impact of adaptogens on reproductive function remains understudied. This review examines the effects of common adaptogens on male and female reproductive functions, highlighting their regulation of neuro-endocrine-immune interactions crucial for reproduction. While existing literature reveals varying impacts on reproductive function, most adaptogens exhibit beneficial effects, modulating neuroimmunology and promoting gonadal steroidogenesis, spermatogenesis, and folliculogenesis through direct mechanisms or suppression of oxidative stress and inflammation. Further experimental research is necessary to elucidate the mechanisms of action of adaptogens, which would significantly advance the management of reproductive disorders and other diseases. Validating these findings in clinical trials is also essential.

Abstract
Prostate cancer (PCa) accounts for roughly 15% of diagnosed cancers among men, with disease incidence increasing worldwide. Age, family history and ethnicity, diet, physical activity, and chemoprevention all play a role in reducing PCa risk. The prostate is an exocrine gland that is characterized by its multi-functionality, being involved in reproductive aspects such as male ejaculation and orgasmic ecstasy, as well as playing key roles in the regulation of local and systemic concentrations of 5α-dihydrotestosterone. The increase in androgen receptors at the ventral prostate is the first elevated response induced by copulation. The regulation of prostate growth and function is mediated by an androgen-dependent mechanism. Binding 5-DHT to androgen receptors (AR) results in the formation of a 5α-DHT:AR complex. The interaction of the 5α-DHT:AR complex with the specific DNA enhancer element of androgen-regulated genes leads to the regulation of androgen-specific target genes to maintain prostate homeostasis. Consequently, ejaculation may play a significant role in the reduction of PCa risk. Thus, frequent ejaculation in the absence of risky sexual behavior is a possible approach for the prevention of PCa. In this review, we provide an insight into possible mechanisms regulating the impact of frequent ejaculation on reducing PCa risk.

Abstract
Numerous aspects of spinal cord injury have undergone extensive research over the years. However, amid this comprehensive exploration, one crucial aspect remains insufficiently emphasized: sexuality. Despite its paramount importance to individuals' holistic well-being, sexuality often receives inadequate attention within rehabilitation programs. In this article, we aim to underscore the significance of addressing this dimension comprehensively, especially given its increasing recognition and exploration in recent years.

Anatomic maps of erogenous and aversive sensation zones of the breasts, vulva, and vagina: a questionnaire-based study. J Sex Med 2025; 22:7-13. [PMID: 39566929 DOI: 10.1093/jsxmed/qdae143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2024] [Revised: 09/27/2024] [Accepted: 10/30/2024] [Indexed: 11/22/2024]
Abstract
BACKGROUND Erogenous sensation zones (ESZs) elicit sexual pleasure upon stimulation. General ESZ maps exist, but they do not assess internal areas of the body, differentiate between individual structures, or quantify the importance of individual ESZs to sexual pleasure. Maps of aversive sensation zones (ASZs), or bodily areas individuals dislike having touched during sex, have not been described. AIM To create detailed erogenous and aversive sensory maps of the vulva, vagina, and breasts, and assess the importance of each erogenous structure to sexual pleasure. METHODS An anonymous online questionnaire was administered to 441 sexually active cisgender women (mean age 48.9 ± 15.5 years) from March to June 2020 via Qualtrics. Respondents selected ESZs and ASZs from anatomic illustrations and rated each ESZ's importance to their sexual pleasure. Respondents' reasoning for choosing each ASZ was queried. OUTCOMES Heat maps of ESZ and ASZ selection frequency, ESZ importance ratings, and ASZ reasoning. RESULTS More respondents selected ≧1 areas of the vulva as erogenous (82.0%), in comparison to the breasts (77.4%) and vagina (59.4%). The two most erogenous areas of the breast were also the most aversive: breast tissue (57.8% ESZ selection; 5.4% ASZ) and nipples (42.7%; 6.5%). Respondents most commonly reported these areas as aversive due to: "It's overly sensitive" and "It hurts."The most frequently selected ESZs of the vulva were the vaginal introitus (50.8%), periurethra (42.6%), and glans clitoris (41.3%). The top ASZs were the anus (34.0%) and perineum (7.9%), with primary reasons being: "It's gross," "It hurts," and "I'm ashamed/embarrassed."Of the five ESZs of the vagina, the superficial anterior (48.1%) and superficial posterior (32.9%) regions were the most selected. The cervix (6.8%), superficial posterior (5%), and deep posterior (3.4%) regions were the top ASZs due to "It hurts" and/or "It's overly sensitive." CLINICAL IMPLICATIONS Erogenous and aversive sensory maps could help identify sexual concerns, inform preoperative counseling, and track sensory changes. STRENGTHS AND LIMITATIONS This study captured detailed maps of internal and external ESZs and ASZs of the breasts, vulva, and vagina. Limitations include recall bias and inclusion of only cisgender women, rather than all people who share the same anatomy, irrespective of gender identity. CONCLUSIONS Erogenous sensation was most prominent in the vulvar structures, including the vaginal introitus and glans clitoris, followed by the superficial surface of the vaginal canal. Aversive sensation associated with the anus primarily came from feelings of judgment and shame, while other ASZs were reportedly due to pain and sensitivity.

Abstract
Female sexual dysfunction (FSD) is prevalent among women with multiple sclerosis (MS), leading to significant impairments in quality of life. Despite various available treatments, current approaches often fail to address the complex, multifactorial nature of FSD in this population. Transcutaneous tibial nerve stimulation (TTNS) has recently gained attention as a non-invasive neuromodulation therapy that has demonstrated potential benefits for neurogenic bladder dysfunction, with preliminary evidence suggesting overlapping improvements in sexual function. This narrative review synthesizes current evidence on the use of TTNS for managing FSD in women with MS. A comprehensive literature search of Medline, Web of Science, and Scopus was conducted, focusing on studies that explored TTNS interventions and outcomes in MS-related FSD. The findings indicate that TTNS likely modulates pelvic neural pathways, enhances genital blood flow, and improves key sexual function domains, including arousal, lubrication, and orgasm. Clinical studies using validated assessment tools, such as the Female Sexual Function Index (FSFI), have shown significant improvements in sexual outcomes, particularly when TTNS is combined with pelvic floor muscle training (PFMT). Experimental models further support the plausibility of these findings, linking TTNS to increased pelvic perfusion and more balanced neurogenic regulation of sexual response. Although initial evidence suggests that TTNS is safe, effective, and well-tolerated, limitations include small sample sizes, short follow-up periods, and variability in treatment protocols. Future research should focus on larger controlled trials, long-term follow-up studies, and standardized intervention parameters to optimize the application of TTNS for addressing FSD in women with MS.

Abstract
Despite a large body of biomedical research, little is known about the psychological and perceptual predictors of sexual satisfaction (SS) and sexual distress (SD) post spinal cord injury (SCI). Guided by a bio-psycho-perceptual framework, this cross-sectional research aimed at assessing SS and SD in a large SCI sample using validated patient-reported outcome measures (PROM). Significant correlates and predictors of SS and SD were also identified. Ninety-one men and women with SCI completed PROMs of SS and SD, as well as psychological (mood, sexual and body esteem) and perceptual (interoceptive awareness, trait mindfulness, sexual mindfulness) factors. Neurological profiles were also assessed, along with experience of orgasm. Correlates of SS and SD were first identified using Pearson's correlations, then multiple hierarchical regression models were computed to isolate predictors. Orgasm experience and psychological factors emerged as moderate correlates of both SS and SD, while neurological factors did not. Interoceptive awareness and trait mindfulness showed weak associations with SD and none with SS. Among the tested predictors, experience of orgasm emerged as the strongest for SS (β = -.29, p < .01), followed by mood, which predicted SS and SD. Sexual and body esteem was predictive of SD only. In sexually active participants, sexual mindfulness predicted both SS (β = 0.55, p < .001) and SD (β = -0.56, p < .001) above and beyond all other variables. This study reveals unique aspects of SS and SD postinjury and supports further consideration of psychological and perceptual dimensions of SCI sexuality in rehabilitation research.

Abstract
INTRODUCTION Sexual dysfunction (SD) is a common symptom that affects 40-90% of patients with multiple sclerosis (MS). Previous studies have highlighted the negative impact of sexual dysfunction in the mental health status and overall quality of life in patients with MS. METHODS The aim of this study was to examine the effects of transcutaneous tibial nerve stimulation (TTNS) in the primary SD symptoms in patients with MS. A total of 40 participants were randomized (1:1 ratio) to either TTNS or Sham group and received three 20 min sessions over the course of two months. Pre and post intervention SD was evaluated using the Multiple Sclerosis Intimacy Questionnaire (MISQ-15). RESULTS Statistically significant improvements in the aspects of primary sexual dysfunction were observed in the TTNS group pre-post intervention (specifically erectile function (for males)/vaginal lubrication (for females) (p < .001), orgasm quality and satisfaction for both male and female patients (p < .001), sexual desire (p < .05) and bladder related symptomatology (p < .005). In the sham group pre-post intervention, the only observed improvement was in the sexual desire aspect (p < .05). Post intervention the groups significantly differed erectile function/vaginal lubrication and orgasm quality and satisfaction (p < .05). CONCLUSIONS Our findings underline the efficacy of TTNS in improving primary SD symptoms as well as bladder problems in both male and female patients with MS. TTNS demonstrated significant improvement in the following domains: erectile function, vaginal lubrication, orgasm quality, satisfaction, bladder-related symptoms, and sexual desire.

Abstract
Background Little is known about the incidence, management or long-term outcomes of traumatic cauda equina syndrome (CES), with few cohort studies. The purpose of this study is to establish the incidence and long-term outcomes of traumatic CES in Victoria, Australia. This study is a registry-based cohort study, and people with a diagnosis of traumatic CES from 2010 to 2022 were recruited from the Victorian State Trauma Registry. Methods An incidence rate was calculated by dividing the amount of new cases each year by the estimated population in Victoria. Demographic, injury and hospital admission details were extracted from the Victorian State Trauma Registry. Routine follow-up occurred at 6, 12- and 24- months postinjury, with a focus on health-related quality of life outcomes using the EuroQol EQ-5D scale, level of disability using the World Health Organization Disability Assessment Schedule (WHODAS) score and return to work outcomes. An additional telephone interview undertaken at a median 6.8 years postinjury collected the EQ-5D, bowel and bladder outcomes. Descriptive statistics were used to analyse data. Mixed effects regression modelling was used to model change in EQ-5D outcomes over time. Results Of the 94 participants, most were men (67%), the median age at injury was 41 years, and the most common cause was road trauma (35%). The incidence rate ranged from 0.56 to 2.51 per million per year. Most people reported problems on the EQ-5D at all 4 follow-up time points, with no clear improvement over time. 47% of people had not returned to work 24 months after injury. Of the survivors who completed the additional follow-up, 41% of people experienced constipation and 51% reported almost losing bladder continence at least once per week. Conclusions While the incidence rate of traumatic CES was low, most people experienced long-term sequelae, highlighting the impact of this injury on peoples' lives. Multijurisdictional studies may be needed to comprehensively measure the impacts of this injury.

[PMID: 39319159 PMCID: PMC11419871 DOI: 10.1016/j.heliyon.2024.e37309] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 06/08/2024] [Accepted: 08/30/2024] [Indexed: 09/26/2024] Open
Abstract
Introduction This study aimed to compare the clinical efficacy of sexual stimulation with that of placebo in the treatment of distal ureteral stones. Methods We searched PubMed, Web of Science, Cochrane Library, and Google Scholar from January 1, 2000 to December 31, 2022 for studies comparing the efficacy of sexual stimulus with that of placebo for the treatment of distal ureteral stones. RevMan 5.3 software was used to pool the data. The study protocol was registered on PROSPERO (Registration Number: CRD42023432408). Results A total of six randomized controlled trials comprising 535 cases of distal ureteral stones were included in this study. Among these, 273 cases were associated with sexual intercourse or masturbation 3-4 times a week, while 262 cases only received symptomatic treatment. The pooled results showed that the 2-week [risk ratios (RR) = 1.77, 95 % confidence interval (CI): 1.34, 2.33] and 4-week [RR = 1.48, 95 % CI: 1.29, 1.69] ureteral stone expulsion rates of the sexually stimulated group were significantly higher than those of the placebo group (ps < 0.01). Additionally, sexual stimulation was associated with a shorter ureteral stone expulsion time [weighted mean differences (WMD) = -3.74, 95 % CI: -6.27, -1.22, p < 0.01] and a decreased prevalence of renal colic attacks [WMD = -0.61, 95 % CI: -1.01, -0.22, p < 0.01] compared with those of the placebo group. Conclusion Appropriate sexual stimulation can enhance the spontaneous expulsion of distal ureteral stones in patients presenting with tolerable pain.

Abstract
This study aimed to determine whether male stress is related to seminal stress biomarkers and pregnancy achievement in women exposed to their partner's seminal plasma (SP) in the intracytoplasmic sperm injection (ICSI) cycle. In this pilot prospective study, 20 couples undergoing ICSI, as well as 5 fertile sperm donors and 10 saliva donors, were investigated. Women were exposed to their partner's SP via unprotected sexual intercourse during the ICSI cycle and intravaginal application on the day of ovum pick-up (Day-OPU). Semen samples were collected from male partners by masturbation on the Day-OPU. Saliva and serum samples were collected prior to masturbation. Body fluids were frozen at - 80 °C until assayed. Biomarkers of activity of the sympathetic adrenomedullary axis (salivary alpha-amylase and adrenaline), sympathetic neural axis (noradrenaline and dopamine), hypothalamic-pituitary-adrenal (HPA) system (cortisol), and immune system (C-reactive protein and interleukin (IL)-18) were estimated to examine their association with SP composition and clinical pregnancy achievement. The clinical pregnancy rate was 45.0%. In the unsuccessful ICSI group, blunted levels of salivary and serum cortisol were found compared to the successful ICSI group and the fertile sperm donors. With regard to seminal markers, decreased cortisol level and elevated noradrenaline, noradrenaline/cortisol ratio, and lL-18 levels were strongly associated with ICSI failure (areas under the ROC curves were, 0.813, 0.848, 0.899, and 0.828, respectively). These findings confirm that stress response systems activity affects SP composition, which in turn is associated with ICSI outcomes in women exposed to their partner's SP during an ICSI cycle.

Short-Term Dorsal Genital Nerve Stimulation Increases Subjective Arousal in Women With and Without Spinal Cord Injury: A Preliminary Investigation. Neuromodulation 2024; 27:681-689.

Abstract
OBJECTIVES Female sexual dysfunction (FSD) affects an estimated 40% of women. Unfortunately, FSD is understudied, leading to limited treatment options for FSD. Neuromodulation has shown some success in alleviating FSD symptoms. We developed a pilot study to investigate the short-term effect of electrical stimulation of the dorsal genital nerve and tibial nerve on sexual arousal in healthy women, women with FSD, and women with spinal cord injury (SCI) and FSD. MATERIALS AND METHODS This study comprises a randomized crossover design in three groups: women with SCI, women with non-neurogenic FSD, and women without FSD or SCI. The primary outcome measure was change in vaginal pulse amplitude (VPA) from baseline. Secondary outcome measures were changes in subjective arousal, heart rate, and mean arterial pressure from baseline. Participants attended one or two study sessions where they received either transcutaneous dorsal genital nerve stimulation (DGNS) or tibial nerve stimulation (TNS). At each session, a vaginal photoplethysmography sensor was used to measure VPA. Participants also rated their level of subjective arousal and were asked to report any pelvic sensations. RESULTS We found that subjective arousal increased significantly from before to after stimulation in DGNS study sessions across all women. TNS had no effect on subjective arousal. There were significant differences in VPA between baseline and stimulation, baseline and recovery, and stimulation and recovery periods among participants, but there were no trends across groups or stimulation type. Two participants with complete SCIs experienced genital sensations. CONCLUSIONS To our knowledge, this is the first study to measure sexual arousal in response to short-term neuromodulation in women. This study indicates that short-term DGNS but not TNS can increase subjective arousal, but the effect of stimulation on genital arousal is inconclusive. This study provides further support for DGNS as a treatment for FSD.

Abstract
The ability to experience pleasurable sexual activity is important for human health. Receptive anal intercourse (RAI) is a common, though frequently stigmatized, pleasurable sexual activity. Little is known about how diseases of the colon, rectum, and anus and their treatments affect RAI. Engaging in RAI with gastrointestinal disease can be difficult due to the unpredictability of symptoms and treatment-related toxic effects. Patients might experience sphincter hypertonicity, gastrointestinal symptom-specific anxiety, altered pelvic blood flow from structural disorders, decreased sensation from cancer-directed therapies or body image issues from stoma creation. These can result in problematic RAI - encompassing anodyspareunia (painful RAI), arousal dysfunction, orgasm dysfunction and decreased sexual desire. Therapeutic strategies for problematic RAI in patients living with gastrointestinal diseases and/or treatment-related dysfunction include pelvic floor muscle strengthening and stretching, psychological interventions, and restorative devices. Providing health-care professionals with a framework to discuss pleasurable RAI and diagnose problematic RAI can help improve patient outcomes. Normalizing RAI, affirming pleasure from RAI and acknowledging that the gastrointestinal system is involved in sexual pleasure, sexual function and sexual health will help transform the scientific paradigm of sexual health to one that is more just and equitable.

Abstract
Background Sexual dysfunction is highly prevalent in males with spinal cord injury (SCI) and has been recognized to be a key recovery priority. Objectives This cross-sectional, mixed-methods study aimed to investigate the major themes linked to sexual functioning in males with chronic (>1 year) SCI. Methods Twenty male participants with SCI, aged 25 to 59 years, completed validated questionnaires exploring sexual function/satisfaction and health-related quality of life and a semi-structured interview with an experienced sexual medicine physician. Sex hormone concentrations and metabolic biomarkers, along with body composition and habitual physical activity levels, were assessed. Interview recordings were transcribed and thematic analysis performed using combined COM-B (Capability, Opportunity, Motivation, and Behavior) and biopsychosocial models to identify and organize major contributors and barriers to sexual functioning. Results Metabolic and hormonal biomarkers largely fell within normal physiological ranges despite reduced sexual functioning reported in our cohort (19/20 participants reported some degree of erectile dysfunction). Qualitative analysis of interview transcripts revealed 24 themes. Adaptability was important for improving sexual satisfaction. Attraction and attentiveness to sex and partners remained stable over time, while the desire for intimacy increased post injury. Sexual social norms, and comparisons to the able-bodied population, provided challenges for sexual activity and partnership. Environmental concerns regarding access to sexual health resources and accessible physical spaces during intimacy were relevant. Mood disorders and general life stressors negatively impacted sexual desire, while physical activity encouraged sexual activity. Conclusion By considering a holistic view of sexuality in males with SCI, we identified key contributors and barriers to sexual functioning for the cohort studied.

Abstract
PURPOSE Spinal cord injury (SCI) leads to sensorimotor impairments; however, it can also be complicated by significant autonomic dysfunction, including cardiovascular and lower urinary tract (LUT) dysfunctions. Autonomic dysreflexia (AD) is a dangerous cardiovascular complication of SCI often overlooked by healthcare professionals. AD is characterized by a sudden increase in blood pressure (BP) that can result in severe cardiovascular and cerebrovascular complications. In this review, we provide an overview on the clinical manifestations, risk factors, underlying mechanisms, and current approaches in prevention and management of AD. METHODS After conducting a literature research, we summarized relevant information regarding the clinical and pathophysiological aspects in the context of urological clinical practice CONCLUSIONS: The most common triggers of AD are those arising from LUT, such as bladder distention and urinary tract infections. Furthermore, AD is commonly observed in individuals with SCI during urological procedures, including catheterization, cystoscopy and urodynamics. Although significant progress in the clinical assessment of AD has been made in recent decades, effective approaches for its prevention and treatment are currently lacking.

Abstract
OBJECTIVE To evaluate the quality of sexual life in men with spinal cord injury. DESIGN Cross-sectional analytical study. PATIENTS Males with a history of spinal cord injury who attended an outpatient rehabilitation service. METHODS An analytical study examined adult male patients with complete spinal cord injury in rehabilitation. A modified Sexual Life Quality Questionnaire (SLQQ) examined quality of sexual life, with scores below 50 suggesting significant sexual dysfunction and dissatisfaction. The assessment evaluated age, occupation, marital status, comorbidities, and treatment methods. RESULTS A total of 80 patients were included; 33 (41%) had a thoracic spinal cord injury, and 47 (59%) had a lumbar spinal cord injury. Thirty-seven patients (46%) were dissatisfied with the quality of their sexual life; 29 patients (88%) with thoracic spinal cord injury and 8 patients (17%) with lumbar spinal cord injury were dissatisfied with the quality of their sexual life (p = 0.001). Patients with higher education level experienced less sexual dissatisfaction (p = 0.03). CONCLUSION Human sexuality involves numerous interconnected elements that impact on general health. Sexual pleasure, self-esteem, and personal relationships are crucial for patients with spinal cord injury to identify rehabilitation needs. These results indicate the importance of supporting sexual well-being in recovery. Further studies of sexual enjoyment and quality of life for patients with spinal cord injury are needed, using larger and more diverse populations.

Abstract
Colorectal cancer is a significant cause of cancer-related deaths worldwide. Although advances in surgical technology and technique have decreased mortality rates, surviving patients often experience sexual dysfunction as a common complication. The development of the lower anterior resection has greatly decreased the use of the radical abdominoperineal resection surgery, but even the less radical surgery can result in sexual dysfunction, including erectile and ejaculatory dysfunction. Improving the knowledge of the underlying causes of sexual dysfunction in this context and developing effective strategies for preventing and treating these adverse effects are essential to improving the quality of life for postoperative rectal cancer patients. This article aims to provide a comprehensive evaluation of erectile and ejaculatory dysfunction in postoperative rectal cancer patients, including their pathophysiology and time course and strategies for prevention and treatment.

Abstract
Spinal cord injury (SCI) produces damage to the somatic and autonomic pathways that regulate lower urinary tract, sexual, and bowel function, and increases the risk of autonomic dysreflexia. The recovery of these functions has a high impact on health, functioning, and quality of life and is set as the utmost priority by patients. The application of reliable models to predict lower urinary tract, sexual, and bowel function, and autonomic dysreflexia is important for guiding counseling, rehabilitation, and social reintegration. Moreover, a reliable prediction is essential for designing future clinical trials to optimize patients' allocation to different treatment groups. To date, reliable and simple algorithms are available to predict lower urinary tract and bowel outcomes after traumatic and ischemic SCI. Previous studies identified a few risk factors to develop autonomic dysreflexia, albeit a model for prediction still lacks. On the other hand, there is an urgent need for a model to predict the evolution of sexual function. The aim of this review is to examine the available knowledge and models for the prediction of lower urinary tract, sexual, and bowel function, and autonomic dysreflexia after SCI, and critically discuss the research priorities in these fields.

Abstract
Prostate cancer treatment has substantial effects on sexual health and function. Sexual function is a vital aspect of human health and a critical component of cancer survivorship, and understanding the potential effects of different treatment modalities on sexual health is crucial. Existing research has extensively described the effects of treatment on male erectile tissues necessary for heterosexual intercourse; however, evidence regarding their effects on sexual health and function in sexual and gender minority populations is minimal. These groups include sexual minority - gay and bisexual - men, and transgender women or trans feminine people in general. Such unique effects in these groups might include altered sexual function in relation to receptive anal and neovaginal intercourse and changes to patients' role-in-sex. Sexual dysfunctions following prostate cancer treatment affecting quality of life in sexual minority men include climacturia, anejaculation, decreased penile length, erectile dysfunction, and problematic receptive anal intercourse, including anodyspareunia and altered pleasurable sensation. Notably, clinical trials investigating sexual outcomes after prostate cancer treatment do not collect sexual orientation and gender identity demographic data or outcomes specific to members of these populations, which perpetuates the uncertainty regarding optimal management. Providing clinicians with a solid evidence base is essential to communicate recommendations and tailor interventions for sexual and gender minority patients with prostate cancer.

Abstract
Sexual dysfunction is a common consequence for women with spinal cord injury (SCI); however, current treatments are ineffective, especially in the under-prioritized population of women with SCI. This case-series, a secondary analysis of the Epidural Stimulation After Neurologic Damage (E-STAND) clinical trial aimed to investigate the effect of epidural spinal cord stimulation (ESCS) on sexual function and distress in women with SCI. Three females, with chronic, thoracic, sensorimotor complete SCI received daily (24 h/day) tonic ESCS for 13 months. Questionnaires, including the Female Sexual Function Index (FSFI) and Female Sexual Distress Scale (FSDS) were collected monthly. There was a 3.2-point (13.2%) mean increase in total FSFI from baseline (24.5 ± 4.1) to post-intervention (27.8 ± 6.6), with a 4.8-50% improvement in the sub-domains of desire, arousal, orgasm and satisfaction. Sexual distress was reduced by 55%, with a mean decrease of 12 points (55.4%) from baseline (21.7 ± 17.2) to post-intervention (9.7 ± 10.8). There was a clinically meaningful change of 14 points in the International Standards for Neurological Classification of Spinal Cord Injury total sensory score from baseline (102 ± 10.5) to post-intervention (116 ± 17.4), without aggravating dyspareunia. ESCS is a promising treatment for sexual dysfunction and distress in women with severe SCI. Developing therapeutic interventions for sexual function is one of the most meaningful recovery targets for people with SCI. Additional large-scale investigations are needed to understand the long-term safety and feasibility of ESCS as a viable therapy for sexual dysfunction.

Abstract
Spinal cord injuries lead to permanent physical impairment despite most often being anatomically incomplete disruptions of the spinal cord. Remaining connections between the brain and spinal cord create the potential for inducing neural plasticity to improve sensorimotor function, even many years after injury. This narrative review provides an overview of the current evidence for spontaneous motor recovery, activity-dependent plasticity, and interventions for restoring motor control to residual brain and spinal cord networks via spinal cord stimulation. In addition to open-loop spinal cord stimulation to promote long-term neuroplasticity, we also review a more targeted approach: closed-loop stimulation. Lastly, we review mechanisms of spinal cord neuromodulation to promote sensorimotor recovery, with the goal of advancing the field of rehabilitation for physical impairments following spinal cord injury.

Abstract
INTRODUCTION Studies demonstrate the connection between adverse sexual function and medical conditions such as diabetes and heart disease. However, in the areas of spinal and spinal cord pathologies that require surgical interventions, there are scant data. OBJECTIVES We undertook a narrative review to synthesize what is known on the topic, raise awareness, and call for action. METHODS PubMed and Google Scholar identified case reports and primary studies evaluating female sexual dysfunction associated with spinal pathology as well as surgical intervention success were reviewed to contextualize and characterize female sexual dysfunction. RESULTS Available case reports and primary studies suggest that female sexual dysfunction can result from traumatic spinal etiologies, malignant tumors, and benign tumors with and without bony involvement. Although identified as a key preoperative predictor in maintenance or improvement of neurologic status, sexuality is rarely addressed in the neurosurgical care plan. In spinal stenosis and degenerative spine disease, over half of patients report pain with sexual activity. Importantly, while pain can hinder sexual activity in females, there are other sexual issues, including desire and subjective arousal, lubrication, orgasm, and satisfaction that are usually not explored. Studies show the impact of spinal pathologies on frequency of sexual intercourse, hypoesthesia, anorgasmia, and depression. Surgical intervention of spinal pathologies has been cited to improve back pain however other types of sexual dysfunction usually fails to improve after surgical intervention. CONCLUSIONS The lack of high-quality research with adequate numbers of female participants that appropriately characterizes the nuances of female sexual dysfunction across various spinal pathologies, with post-surgical intervention analysis and consideration of surgical approach, necessitates consideration for future study. A pre-op and post-op sexual history in all woman undergoing spinal surgery should be a standard of care. Moscicki P, Bachmann GA.

Abstract
Spinal cord injury chronically alters cardiac structure and function and is associated with increased odds for cardiovascular disease. Here, we investigate the cardiac consequences of spinal cord injury on the acute-to-chronic continuum, and the contribution of altered bulbospinal sympathetic control to the decline in cardiac function following spinal cord injury. By combining experimental rat models of spinal cord injury with prospective clinical studies, we demonstrate that spinal cord injury causes a rapid and sustained reduction in left ventricular contractile function that precedes structural changes. In rodents, we experimentally demonstrate that this decline in left ventricular contractile function following spinal cord injury is underpinned by interrupted bulbospinal sympathetic control. In humans, we find that activation of the sympathetic circuitry below the level of spinal cord injury causes an immediate increase in systolic function. Our findings highlight the importance for early interventions to mitigate the cardiac functional decline following spinal cord injury. By combining experimental models with prospective clinical studies, the authors show that spinal cord injury causes a rapid reduction in cardiac function that precedes structural changes, and that the loss of descending sympathetic control is the major cause of reduced cardiac function following spinal cord injury.

Abstract
Sexual dysfunction is a common, poorly recognized, poorly discussed (often because of cultural perceptions and sensitivities), bothersome and neglected aspect of the range of non-motor symptoms of Parkinson's disease (PD). The spectrum of sexual dysfunction in PD ranges from hyposexuality-based disturbances to hypersexuality-dominated behaviors in the context of drug-induced impulse control disorder. The pathophysiological mechanisms underlying PD-related sexual dysfunction, specifically for hyposexual disorders, are thus heterogeneous and still not fully understood. However, central and peripheral neural mechanisms secondary to the hallmark pathological alterations of the disease (alpha-synuclein deposition and nigrostriatal degeneration) and to the associated network and neurotransmitter dysfunctions, together with the effects of dopaminergic therapies, seem to play an important role in the development of sexual disturbances. In this chapter, we therefore review the neuroanatomical and neurophysiological basis of sexual function in humans, and we provide insights on the pathophysiological mechanisms of hyposexuality and hypersexuality in PD.

Abstract
BACKGROUND Women with spinal cord injuries usually suffer from sexual dysfunction, such as alterations during arousal and an increase in the time to reach orgasm. However, little evidence has been found on its physiotherapeutic approach, as well as poor adherence to the latter. The aim of this study is to determine the effectiveness of two interventions to improve sexual dysfunction: the application of genital vibration and transcutaneous tibial nerve stimulation. METHODS This is a randomized clinical trial that will recruit 54 women who, one year after a spinal cord injury, suffer from sexual dysfunction associated with the latter. The participants will be randomized to three groups: (a) intervention group 1 treated with transcutaneous tibial nerve electrostimulation (n = 18), (b) intervention group 2 treated with genital vibration (n = 18), and (c) a control group (n = 18). The treatment time will be 12 weeks. Adherence to the treatment will be evaluated, as well as the effectiveness of the treatment, through the Female Sexual Function Index, the Sexual Quality of Life-Female questionnaire, quantitative sensory tests, and the improvement reported by the patient in terms of arousal and orgasm. The evaluations will be carried out before the treatment, at the end of the treatment and 3, 6 and 12 months after the end of the treatment.

[PMID: 35027722 DOI: 10.1038/s41443-022-00527-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2021] [Revised: 12/12/2021] [Accepted: 01/04/2022] [Indexed: 11/09/2022]
Abstract
Ejaculation is often impaired in men with spinal cord injury (SCI). The aim of this prospective study was to assess sequence of sphincteric events and ejaculation dyssynergia during penile vibratory stimulation (PVS) in SCI men. Simultaneous recordings of bladder, bladder neck, prostate and external urethral sphincter pressures were performed using a microtip catheter with 5 pressure transducers. Between 2017 and 2019, ten men participated in the study for a total of 17 procedures. Antegrade ejaculation was found in three men with upper motor neuron (UMN) lesion. Ejaculation was preceded by a progressive increase in all urethral pressures, reaching sustained (plateau) or intermittent peaks above 220 cm H20. Antegrade ejaculation occurred after intermittent decreases in pressure at the external urethral sphincter level down to 100 cm H20, while the pressure at the bladder neck remained high (up to or above 220 cm H20). PVS was ineffective in eliciting ejaculation in seven men. In the five patients with UMN lesions, PVS elicited an increase in the external urethral sphincter pressure (mean 51 cm H20), while there was no pressure change in the two patients with lower motor neuron lesions. Due to lack of enough retrograde retrieval attempts, the hypothesis of ejaculatory dyssynergia could not be verified.

Abstract
This study compares remote neurodegenerative changes caudal to a cervical injury in degenerative cervical myelopathy (DCM) (i.e., non-traumatic) and incomplete traumatic spinal cord injury (tSCI) patients, using MRI-based tissue area measurements and diffusion tensor imaging (DTI). Eighteen mild to moderate DCM patients with sensory impairments (mJOA score: 16.2±1.9), 14 incomplete tetraplegic tSCI patients (AIS C&D), and 20 healthy controls were recruited. All participants received DTI and T2*-weighted scans in the lumbosacral enlargement (caudal to injury) and at C2/C3 (rostral to injury). MRI readouts included DTI metrics in the white matter (WM) columns and cross-sectional WM and gray matter area. One-way ANOVA with Tukey's post-hoc comparison (p<0.05) was used to assess group differences. In the lumbosacral enlargement, compared to DCM, tSCI patients exhibited decreased fractional anisotropy in the lateral (tSCI vs. DCM, -11.9%, p=0.007) and ventral WM column (-8.0%, p=0.021), and showed trend toward lower values in the dorsal column (-8.9%, p=0.068). At C2/C3, compared to controls, fractional anisotropy was lower in both groups in the dorsal (DCM vs. controls, -7.9%, p=0.024; tSCI vs. controls, -10.0%, p=0.007) and in the lateral column (DCM: -6.2%, p=0.039; tSCI: -13.3%, p<0.001), while tSCI patients had lower fractional anisotropy than DCM patients in the lateral column (-7.6%, p=0.029). WM areas were not different between patient groups but were lower compared to controls in the lumbosacral enlargement (DCM: -16.9%, p<0.001; tSCI, -10.5%, p=0.043) and at C2/C3 (DCM: -16.0%, p<0.001; tSCI: -18.1%, p<0.001). In conclusion, mild to moderate DCM and incomplete tSCI lead to similar degree of degeneration of the dorsal and lateral columns at C2/C3, but tSCI results in more widespread white matter damage in the lumbosacral enlargement. These remote changes are likely to contribute to the patients' impairment and recovery. DTI is a sensitive tool to assess remote pathological changes in DCM and tSCI patients.

Abstract
INTRODUCTION Post-SSRI sexual-dysfunction (PSSD) is an iatrogenicsyndrome, the underlying neurobiological mechanisms of which areunclear. Symptom onset follows cessation of serotonergicantidepressants i.e. Selective Serotonin and Norepinephrine ReuptakeInhibitors (SSRI's, SNRI's), and Tricyclic antidepressants (TCA's). PSSDsymptoms include genital anesthesia, erectile dysfunction andorgasmic/ejaculatory anhedonia, and should be differentiated fromdepression-related sexual-dysfunction. Recently, accumulated data of numerous case-reports suggest additional non-sexual symptoms including, anhedonia, apathy, and blunted affect. PSSD gained official recognition after the European medical agency concluded that PSSD is a medical condition that persists after discontinuation of SSRI's and SNRI's. OBJECTIVE To review possible underlying neurobiological mechanisms ofthis syndrome, update information on the pathophysiology, present a listof potential risk-factors and discuss potential management options forPSSD. METHODS Extensive literature review on the main symptom-patterns ofthis disorder was undertaken using PubMed. It includes introductoryexplications of relevant neurobiology with the objective of generatinghypothesis. RESULTS Precipitating factors for PSSD include previous exposure to certain drugs, genetic predisposition, psychological stress or chemical stressful reaction to antidepressants along pre-existing medical conditions affecting neuroplasticity. Different theories have been proposed to explain the pathophysiology of PSSD: epigenetic gene expression, dopamine-serotonin interactions, serotonin neurotoxicity and hormonal changes. The diagnosis of PSSD is by excluding all other etiologies of sexual-dysfunction. Treatment is challenging, and many strategies have been suggested without definitive outcomes. We offerthe contours of a future neurobiological research agenda, and propose several underlying mechanisms for the various symptoms of PSSD which could be the foundation for a future treatment algorithm. CONCLUSION There is a need for well-designed neurobiological research in this domain, as well as in the prevalence, pathophysiology, and treatment of PSSD. Practitioners should be alert to the distinctive features of PSSD. Misdiagnosing this syndrome might lead to harmful Sexual Medicine Reviews. Peleg LC, Rabinovitch D, Lavie Y, et al.

Abstract
Huntington's disease (HD) can be associated with pathologic involvement beyond the striatum including the autonomic nervous system. Bladder, bowel, and sexual dysfunction have been reported independently in HD, but little is known about their concomitant occurrence. To document this concomitant phenomena, forty-eight subjects (54% male, ages 28-74 years, CAG repeat 38-61) with manifest/symptomatic HD completed detailed questionnaires regarding bladder, bowel, and sexual function. In total, 45 subjects (93.8%) reported symptoms in at least one organ system (bladder, bowel, or sexual), 13 (27.1%) reported symptoms in two systems, and 19 (39.6%) reported concomitant symptoms in all three systems. Urinary problems were most frequent in 42 subjects (87.5%) followed by lower bowel (60.4%) and sexual dysfunction (56.2%). Participants reporting concomitant symptoms were more likely to have longer duration of disease and lower Total Functional Capacity (TFC) scores. This study documents the high frequency of bladder, bowel, and sexual dysfunction in HD and the common occurrence of concomitance of these pelvic organ problems.

Abstract
Erectile dysfunction (ED) is one of the most prevalent chronic conditions affecting men. ED can arise from disruptions during development, affecting the patterning of erectile tissues in the penis and/or disruptions in adulthood that impact sexual stimuli, neural pathways, molecular changes, and endocrine signalling that are required to drive erection. Sexual stimulation activates the parasympathetic system which causes nerve terminals in the penis to release nitric oxide (NO). As a result, the penile blood vessels dilate, allowing the penis to engorge with blood. This expansion subsequently compresses the veins surrounding the erectile tissue, restricting venous outflow. As a result, the blood pressure localised in the penis increases dramatically to produce a rigid erection, a process known as tumescence. The sympathetic pathway releases noradrenaline (NA) which causes detumescence: the reversion of the penis to the flaccid state. Androgen signalling is critical for erectile function through its role in penis development and in regulating the physiological processes driving erection in the adult. Interestingly, estrogen signalling is also implicated in penis development and potentially in processes which regulate erectile function during adulthood. Given that endocrine signalling has a prominent role in erectile function, it is likely that exposure to endocrine disrupting chemicals (EDCs) is a risk factor for ED, although this is an under-researched field. Thus, our review provides a detailed description of the underlying biology of erectile function with a focus on the role of endocrine signalling, exploring the potential link between EDCs and ED based on animal and human studies.

Abstract
OBJECTIVE To conduct a systematic review of self-reported experiences of sexual function and dysfunction in individuals with spina bifida (SB). MATERIALS AND METHODS Medline, Embase, and Web of Science were systematically searched. Studies included contained self-reported data from SB patients on one or more of the following sexual function domains: Genital sensitivity, orgasm, erectile function, ejaculation, lubrication, and/or dyspareunia. Two authors independently assessed eligibility, extracted data, and cross-checked results, with disagreements resolved by consensus. Studies included contained self-reported data from SB patients on one or more of the following sexual function domains: Genital sensitivity, orgasm, erectile function, ejaculation, lubrication, and/or dyspareunia. RESULTS Systematic search yielded 23 studies representing 1441 patients (816 males, 625 females). Eight utilized questionnaires validated in non-SB adults; the remainder used semi-structured interviews and non-validated instruments. Eleven assessed dysfunctions in both sexes, 10 in males, and 2 in females. Erectile function and orgasm were the most commonly assessed outcomes in males and females respectively. 12%-88% of males experienced erectile dysfunction; a majority (51%-90%) reported normal ejaculatory function. Many females were unable to experience orgasm (28%-63%). CONCLUSION Males with SB report significant erectile and ejaculatory dysfunction. Both sexes report impaired orgasms and genital sensitivity. SB-specific instruments assessing sexual dysfunction are needed in order to improve multidisciplinary care for this population.

Abstract
In this systematic review, objectives were to investigate dropout rates, adverse events, and effects of exercise-based therapies on urogenital function and quality of life (QoL) in persons with spinal cord injury (SCI). Database searches were conducted on MEDLINE, EMBASE, and CINAHL for studies examining any form of exercise intervention on urogenital function and/or QoL in adults with SCI. Quality of publications was evaluated using the Joanna Briggs Institute critical evaluation tools. When possible, Hedges' g was calculated for overall effect sizes. Subgroup analyses were conducted on sex and injury severity. Ten studies (228 participants) were included in this review. Three studies examined pelvic floor muscle training, and seven studies examined locomotor training. Overall quality of evidence was low because of small sample sizes and non-randomized designs in most studies. Dropout rates ranged from 12% to 25%, and adverse events were reported only in some studies investigating locomotor training. For lower urinary tract (LUT) outcomes, urodynamic findings were mixed despite moderately positive changes in maximum bladder capacity (g = 0.50) and bladder compliance (g = 0.37). Fairly consistent, but small, improvements were observed in LUT symptoms, primarily bladder awareness and incontinence. LUT QoL improved in most cases. Fewer data were available for sexual outcomes, and only minor improvements were reported. Subgroup analyses, based on sex and severity of injury, were inconclusive. There is some indication for the potential benefit of exercise on urogenital outcomes in persons with SCI, but there is insufficient evidence given the number of studies and heterogeneity of outcome measures.

Abstract
A prerequisite for nerve-sparing pelvic surgery is a thorough understanding of the topographic anatomy of the fine and intricate pelvic nerve networks, and their connections to the central nervous system. Insights into the functions of pelvic nerves will help to interpret disease symptoms correctly and improve treatment. In this article, we review the anatomy and physiology of autonomic pelvic nerves, including their topography and putative functions. The aim is to achieve a better understanding of the mechanisms of pelvic pain and functional disorders, as well as improve their diagnosis and treatment. The information will also serve as a basis for counseling patients with chronic illnesses. A profound understanding of pelvic neuroanatomy will permit complex surgery in the pelvis without relevant nerve injury.

Abstract
After spinal cord injury (SCI), intestinal dysfunction has a serious impact on physical and mental health, quality of life, and social participation. Recent data from rodent and human studies indicated that SCI causes gut dysbiosis. Remodeling gut microbiota could be beneficial for the recovery of intestinal function and motor function after SCI. However, few studies have explored SCI with focus on the gut microbiota and "microbiota-gut-brain" axis. In this review, the complications following SCI, including intestinal dysfunction, anxiety and depression, metabolic disorders, and neuropathic pain, are directly or indirectly related to gut dysbiosis, which may be mediated by "gut-brain" interactions. Furthermore, we discuss the research strategies that can be beneficial in this regard, including germ-free animals, fecal microbiota transplantation, probiotics, phages, and brain imaging techniques. The current microbial research has shifted from descriptive to mechanismal perspective, and future research using new technologies may further demonstrate the pathophysiological mechanism of association of SCI with gut microbiota, elucidate the mode of interaction of gut microbiota and hosts, and help develop personalized microbiota-targeted therapies and drugs based on microbiota or corresponding metabolites.

[PMID: 34223263 PMCID: PMC8244293 DOI: 10.1016/j.xfre.2020.09.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2020] [Revised: 09/23/2020] [Accepted: 09/26/2020] [Indexed: 11/26/2022] Open
Abstract
Objective To examine fertility preservation techniques in the setting of neurosarcoidosis, and to review the impact of corticosteroid and methotrexate therapy on fertility. Design Case report of a patient with infertility secondary to anejaculation associated with spinal neurosarcoidosis, treated with systemic corticosteroids and methotrexate. Setting Academic tertiary-care hospital. Patient(s) A 39-year-old man presented with neurosarcoidosis complicated by acute anejaculation, erectile dysfunction, and hypogonadism. He underwent fertility consultation and sperm cryopreservation before initiating methotrexate therapy. His pretreatment total testosterone was low, at 157 ng/dL. Intervention(s) Unsuccessful pharmacologic therapy and penile vibratory stimulation (PVS) were followed by microdissection testicular sperm extraction (microTESE). Clomiphene was administered for optimization of spermatogenesis before microTESE. Main Outcome Measure(s) Vials of cryopreserved sperm, testis histopathology, and serum testosterone levels. Result(s) Eight vials of viable sperm were harvested by means of micro-TESE and cryopreserved. Despite intraoperative appearance of hypospermatogenesis, 90% of seminiferous tubules had active germ cell sloughing. Total testosterone increased to 278 ng/dL 2 months after initiating clomiphene. Conclusion(s) Conventional fertility preservation techniques may be effective in the setting of neurosarcoidosis-induced infertility owing to largely intact spermatogenesis. PVS, though not effective for this patient, should be considered along with electroejaculation, given high success rates in other patients with neurogenic anejaculation. Corticosteroid-mediated hypogonadism also must be considered in these patients, because it can negatively affect downstream spermatogenesis. In addition, evidence for the impact of paternal methotrexate exposure on fertility is limited and requires further investigation. As such, fertility consultation before initiating methotrexate is highly recommended.

Abstract
PURPOSE To evaluate the effect of masturbation on the spontaneous expulsion of distal ureteral stones 5-10 mm in size. MATERIAL AND METHODS A total of 128 men with distal ureteral stones were randomly divided into 3 groups. All patients received standard medical therapy. Patients in group 1 (n = 43) were instructed to masturbate at least 3-4 times a week, patients in group 2 (n = 41) received tamsulosin 0.4 mg/day, and patients in group 3 (controls, n = 44) received standard medical therapy alone. Rates of expulsion, need for analgesic, and ureterorenoscopic lithotripsy were compared between the groups. RESULTS The mean ages of the patients in groups 1, 2, and 3 were 37 ± 5.0, 37.6 ± 4.6, and 38.4 ± 6.8 years, respectively (p = 0.7). The mean stone size in each group was 6.93 ± 1.1 mm, 7.1 ± 0.9 mm, and 6.87 ± 1.1 mm, respectively (p = 0.4). Spontaneous passage rates in groups 1, 2, and 3 were 81.4%, 80.5%, and 43.2%, respectively, and were significantly higher in group 1 (p = 0.001) and group 2 (p = 0.001) when compared with group 3. Analgesic requirement in groups 1, 2, and 3 was 1.7 ± 0.6, 1.5 ± 0.6, and 1.8 ± 0.6 times per day, respectively, and was significantly lower in the tamsulosin group than in the control group (p = 0.004) CONCLUSION: Masturbation and tamsulosin increased the spontaneous passage of distal ureteral stones 5-10 mm in size. Masturbating at least 3-4 times a week was as effective as tamsulosin. Masturbation and tamsulosin also reduced the need for ureterorenoscopic lithotripsy.

Abstract
Onuf's nucleus is a small group of neurons located in the ventral horns of the sacral spinal cord. The motor neurons (MNs) of Onuf's nucleus innervate striated voluntary muscles of the pelvic floor and are histologically and biochemically comparable to the other somatic spinal MNs. However, curiously, these neurons also show some autonomic-like features as, for instance, they receive a strong peptidergic innervation. The review provides an overview of the histological, biochemical, metabolic, and gene expression peculiarities of Onuf's nucleus. Moreover, it describes the aging-related pathologies as well as several traumatic and neurodegenerative disorders in which its neurons are involved: indeed, Onuf's nucleus is affected in Parkinson's disease (PD) and Shy-Drager Syndrome (SDS), whereas it is spared in Amyotrophic Lateral Sclerosis (ALS), Spinal Muscular Atrophy (SMA), Duchenne Muscular Dystrophy (DMD). We summarize here the milestone studies that have contributed to clarifying the nature of Onuf's neurons and in understanding what makes them either vulnerable or resistant to damage. Altogether, these works can offer the possibility to develop new therapeutic strategies for counteracting neurodegeneration.

Abstract
Genital sensation (GS) is an essential component of male sexual function. Genital sensory disturbance (GSD) caused by spinal cord injury (SCI) has a severe impact on the patients' sexual function but has garnered little research focus. Under normal conditions, GS encompasses the erection, ejaculation, sexual arousal, and orgasm courses associated with physiological and psychological responses in male sexual activity. However, in SCI patients, the deficiency of GS makes the tactile stimulation of the penis unable to cause sexual arousal, disturbs the normal processes of erection and ejaculation, and decreases sexual desire and satisfaction. To provide an overview of the contemporary conception and management of male GS after SCI, we review the innervation and sexual function of male GS in this article, discuss the effects of GSD following SCI, and summarize the current diagnosis and treatment of GSD in male SCI patients.

Abstract
The aim of the study was evaluation of sexual dysfunction in neuro-Behcet's disease (NBD). A total of 25 patients with NBD, 22 patients with Behçet's disease (BD) without neurologic involvement (BDWONI) and 19 persons in control group were prospectively included in the study. We collected all demographic data. A semi-structured interview guided by a Arizona sexual experience scale (ASEX) questionnaire, Beck Depression Inventory and Beck Anxiety Inventory was applied to all of the patients. The sexual dysfunction was significantly higher in patients with NBD (47.9%) compared to patients with BDWONI (35.4%) and control group (16.7%) (p = 0.001). The score of total ASEX, drive, aurosal, vaginal lubrication/penil erection and satisfaction from orgasm were significantly higher in patients with NBD than healthy control group, statistically. Just arousal and lubrication/penile erection scores were significantly higher in NBD group than BDWONI group. Female/Male ratio regarding sexual dysfunction was 43.5/56.5, 29.4/70.6, 62.5/37.5 in NBD, BDWONI and healthy control group, respectively (0 = 0.027). NBD had a negative effect on sexuality in all but especially on arousal and vaginal lubrication/penil erection function based on ASEX questionnaire. Moreover, male sexuality was more affected by BD than female sexuality. Further researches using larger sample sizes are needed to clarify the issues.

Abstract
Sexual dysfunction, following spinal cord injury (SCI), is highly dependent on the extent of injury. SCI disrupts the supraspinal innervation of the reproductive organs; resulting in structural and functional deficits. Relating the extent of SCI to these changes could eventually improve diagnoses and treatment planning of sexual dysfunction following SCI. In the present study, following chronic SCI of different severities (1/3 dorsal SCI (1/3 SCI), 2/3 dorsal SCI (2/3 SCI), and complete transection (Tx)) at T8 spinal level, histological changes of seminiferous tubules parameters in testis were examined. The diameter of seminiferous tubules (DST) and epithelial height of seminiferous tubules (HST) were significantly decreased in all SCI groups compared to control and sham. In addition, DST in 2/3 SCI and Tx groups and HST in Tx group were significantly decreased in comparison with 1/3 SCI animals. Nonetheless, the diameter of seminiferous tubules' lumen decreased significantly in 2/3 SCI and Tx compared to control, sham, and 1/3 SCI groups. Concerning cellular component, the number of spermatocytes and spermatids layers significantly decreased in both 1/3 and 2/3 SCI in comparison to normal. However, Tx had the most prominent deteriorating effect on these layers; indicating impairment in the process of spermatogenesis. These results show that the spinal tracts are part of the neural circuitries innervating the testis and responsible for their structural support. These tracts are mainly distributed between the lateral and ventral funiculi at T8 spinal level. Consequently, sparing ventral funiculi in the SCI prevents the severe decline in spermatogenesis.

Abstract
Sexual dysfunction is common in both men and women with multiple sclerosis but is often under-reported and undertreated. Neurologists report that a major barrier to discussing sexual dysfunction with patients is their lack of knowledge. Here we review the common presentations of sexual dysfunction, discuss its causes in people with multiple sclerosis, and provide a practical approach for neurologists to assess and manage these problems.

Abstract
In men with a spinal cord injury (SCI), erectile function, ejaculation, and fertility are severely impaired. The present study utilized a telemetric pressure transducer implanted into the corpus cavernosum of the penis to examine sexual function during awake mating behavior in a rat contusion model with a range of Infinite Horizon Impactor forces distributed between 150 and 215 kdyn. The mating behavior paradigm included examination of the counts, average pressure, and average duration for mounts, intromissions, and ejaculations. Male Wistar rats were mated with receptive females in 30-min sessions preinjury (sexual acclimation) and once per week for 6 wk beginning after a 2-wk recovery period post-SCI. All SCI animals had significant deficits in sexual function in the parameters measured. These deficiencies were more prevalent in a subset having less than 20% white matter sparing, likely a reflection of the extent of bilateral spino-bulbo-spinal sexual circuitry disruption at the lesion epicenter. The resulting discoordination of the autonomic and somatic reflex control of erection and ejaculation recorded using telemetry devices in an awake, behaving animal model provides an effective means of gauging sexual function deficits after SCI and could have utility for quantifying recovery after a therapeutic intervention.
