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
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
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.

The self-assessment of genital anatomy, sexual function, and genital sensation (SAGASF-M) questionnaire in a Belgian Dutch-speaking male population: A validating study. Andrology 2023; 11:489-500. [PMID: 36426587 DOI: 10.1111/andr.13348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 10/28/2022] [Accepted: 11/15/2022] [Indexed: 11/27/2022]
Abstract
INTRODUCTION Penile and genital surgery for congenital or acquired conditions is daily practice in reconstructive urology. These procedures, which carry the risk of disrupting nerves and blood vessels, may impair the genital sensation, and affect the capacity for sexual pleasure. Self-reported tools are needed to systematically assess the male genitalia before and after reconstructive surgeries in terms of genital sensation and sexual experience. AIM This study validated the Dutch translation of the "self-assessment of genital anatomy and sexual functioning in male" (SAGASF-M) questionnaire and investigated the perceptions of healthy men regarding their genital anatomy and sensory function. METHODS Eight hundred and eight sexually active men with a median age of 39 years (18-79 years) and no history of genital procedures other than circumcision filled out an online version of the questionnaire. Twenty-four participants were randomly recruited to confirm the responses of the "self-assessment of genital anatomy and sexual functioning in male" questionnaire by a clinical evaluation. MAIN OUTCOME MEASURES The "self-assessment of genital anatomy and sexual functioning in male" questionnaire comprises of multiple-choice questions and clarifying illustrations asking men to rate their genital appearance, overall sexual sensitivity, and pain perception as well as the intensity and the effort to reach orgasm. Prespecified regions of the glans, penile shaft, scrotum, perineum, and anus are evaluated through this questionnaire. RESULTS Only slight variability in anatomical ratings was observed. Overall discrimination between different genital areas in terms of genital sensation was significant. The bottom of the glans or frenular area was rated the highest contributor to "sexual pleasure," followed by the other regions of the glans and shaft. The same distribution was found for "orgasm intensity" and "orgasm effort." The anal region was generally rated the lowest. "Discomfort/pain" was rated lower than any of the other sensory function indicators and the top of the glans and anal region were rated most likely to perceive this unpleasant sensation. Participants reported significantly more sexual pleasure and intense orgasms when stimulated by a sexual partner than self-stimulation. Homosexual and bisexual men reported a higher contribution of the perineal and anal regions in sexual pleasure and orgasm. No significant difference between circumcised and uncircumcised individuals regarding overall genital sensation could be found. CONCLUSION The Dutch translation of the SAGASF-M questionnaire is a valuable and reliable tool for self-assessment of genital anatomy and sensation, providing a site-specific attribution of a patient's perceived sexual function. Further prospective research with this questionnaire could aid in the patient-centered improvement of genital surgery.

Abstract
Sexual function which comprises of desire, arousal, orgasm and satisfaction and pain, involves coordinated physiologic responses from multiple different pathways. Sexual dysfunction (SD) occurs when these domains of the sexual response cycle are affected. SD is a common but under-recognized non-motor feature in Parkinson's disease (PD), a common age-related neurodegenerative disorder. SD significantly affects the quality of life of PD patients and their partners. Advanced age, gender, hormone deficiency, neuropsychiatric and medical comorbidities contribute to SD in PD. Possible potential pathological mechanisms include vasculogenic, endocrinologic, neurogenic and psychogenic factors. Various therapeutic interventions, both pharmacological and non-pharmacological modalities have been suggested to improve SD in PD. However, erectile dysfunction (ED) is the only SD with evidence-based treatment available. Non-pharmacological therapies are also offering promising evidence in the improvement of SD. A multidisciplinary approach in the assessment, investigation, and treatment is needed to address the real life complex issues (gender and comorbidities, neurobiological, vasoactive, hormonal as well as psychosocial aspects). Future clinical studies with validated and standardized methods in assessing SD as well as experimental models will be necessary for better insight into the pathophysiology. This would facilitate appropriate therapy and improve sexual rehabilitation in PD patients.

Abstract
STUDY DESIGN Retrospective cohort. OBJECTIVES Delayed ejaculation (DE) is a distressing condition characterized by a notable delay in ejaculation or complete inability to achieve ejaculation, and there are no existing reports of DE following lumbar spine surgery. Inspired by our institutional experience, we sought to assess national rates of DE following surgery of the lumbar spine. METHODS We queried the Optum De-identified Clinformatics Database for adult men undergoing surgery of the lumbar spine between 2003 and 2017. The primary outcome was the development of DE within 2 years of surgery. Multivariable logistic regression was performed to identify factors associated with the development of DE. RESULTS We identified 117 918 men who underwent 162 646 lumbar spine surgeries, including anterior lumbar interbody fusion (ALIF), posterior lumbar fusion (PLF), and more. The overall incidence of DE was 0.09%, with the highest rate among ALIF surgeries at 0.13%. In multivariable analysis, the odds of developing DE did not vary between anterior/lateral lumbar interbody fusion, PLF, and other spine surgeries. A history of tobacco smoking (OR = 1.47, 95% CI 1.00-2.16, P = .05) and obesity (OR = 1.56, 95% CI 1.00-2.44, P = .05) were associated with development of DE. CONCLUSIONS DE is a rare but distressing complication of thoracolumbar spine surgery, and patients should be queried for relevant symptoms at postoperative visits when indicated.

Abstract
Simple Summary Sexual dysfunctions are rarely discussed in our current society. Males experience different sexual dysfunctions, including erectile, infertility, and ejaculatory dysfunctions. In this review only the ejaculatory dysfunction will be discussed. Ejaculation is defined as the ejection of contents collectively from the vas deferens, seminal vesicle, prostate and Cowper’s glands. It is completely controlled by a population of neurons present in the lumbar spinal cord. The presence of lesion in these neurons ceases the ejaculatory behavior in males. This population of neurons was first identified in rats; however, recently it was confirmed that these neurons are present in human males as well. The issues are known as ejaculatory dysfunction. The following are the different types of ejaculatory dysfunctions: early ejaculation, ejaculation into the urinary bladder, late ejaculation and no ejaculation. Abstract Ejaculation is a reflex and the last stage of intercourse in male mammals. It consists of two coordinated phases, emission and expulsion. The emission phase consists of secretions from the vas deferens, seminal vesicle, prostate, and Cowper’s gland. Once these contents reach the posterior urethra, movement of the contents becomes inevitable, followed by the expulsion phase. The urogenital organs are synchronized during this complete event. The L3–L4 (lumbar) segment, the spinal cord region responsible for ejaculation, nerve cell bodies, also called lumbar spinothalamic (LSt) cells, which are denoted as spinal ejaculation generators or lumbar spinothalamic cells [Lst]. Lst cells activation causes ejaculation. These Lst cells coordinate with [autonomic] parasympathetic and sympathetic assistance in ejaculation. The presence of a spinal ejaculatory generator has recently been confirmed in humans. Different types of ejaculatory dysfunction in humans include premature ejaculation (PE), retrograde ejaculation (RE), delayed ejaculation (DE), and anejaculation (AE). The most common form of ejaculatory dysfunction studied is premature ejaculation. The least common forms of ejaculation studied are delayed ejaculation and anejaculation. Despite the confirmation of Lst in humans, there is insufficient research on animals mimicking human ejaculatory dysfunction.

Abstract
Introduction Infertility in men with spinal cord injury (SCI) occurs due to combination of factors like erectile dysfunction, ejaculatory failure, and semen abnormalities. Penile vibratory stimulation (PVS) is a known method of treatment for anejaculation. Predicting successful outcome of PVS depends on several clinical factors, which assess the intactness of the neural arc pertaining to the spinal ejaculation pattern generator. This study reports the clinical predictors for successful candidacy for a PVS trial in males with SCI. Methods Twenty-three males with SCI, satisfying the inclusion criteria, were recruited in this prospective observational study. Participants underwent two trials of PVS with single high-amplitude vibrator. The clinical predictors recorded were neurological level, superficial abdominal reflex, cremasteric reflex, bulbocavernosus reflex, plantar reflex, ankle jerk, knee jerk, lower abdominal sensation, and hip flexor response. In addition, somatic responses during PVS were recorded and corelated. Participants who had successful ejaculation were "responders" and the others were termed as "nonresponders." Binary logistic regression analysis of the clinical parameters was done to compare responders against nonresponders. Results Of the twenty-three males (mean age 33.2 ± 6.8 years) with paraplegia, all four persons with neurological level above T9 had successful ejaculation with PVS. Among all the clinical parameters in the study, presence of somatic responses showed statistical significance in predicting successful ejaculation ( p -value = 0.02). Conclusion This study reports that in men with SCI, along with the level of injury, somatic responses and other clinical reflexes, should be considered concurrently to predict the outcome of vibrator assisted ejaculation.

Abstract
Diabetes mellitus (DM) is a metabolic disorder that is characterized by elevated blood glucose levels due to absolute or relative insulin deficiency, in the background of β-cell dysfunction, insulin resistance, or both. Such chronic hyperglycemia is linked to long-term damage to blood vessels, nerves, and various organs. Currently, the worldwide burden of DM and its complications is in increase. Male sexual dysfunction is one of the famous complications of DM, including abnormal orgasmic/ejaculatory functions, desire/libido, and erection. Ejaculatory dysfunction encompasses several disorders related to DM and its complications, such as premature ejaculation, anejaculation (AE), delayed ejaculation, retrograde ejaculation (RE), ejaculatory pain, anesthetic ejaculation, decreased ejaculate volume, and decreased force of ejaculation. The problems linked to ejaculatory dysfunction may extend beyond the poor quality of life in diabetics as both AE and RE are alleged to alter the fertility potential of these patients. However, although both diabetes patients and their physicians are increasingly aware of diabetic ejaculatory dysfunction, this awareness still lags behind that of other diabetes complications. Therefore, all these disorders should be looked for thoroughly during the clinical evaluation of diabetic men. Besides, introducing the suitable option and/or maneuvers to treat these disorders should be tailored according to each case. This review aimed to explore the most important findings regarding ejaculatory dysfunction in diabetes from pre-clinical and clinical perspectives.

Abstract
INTRODUCTION The process of ejaculation has important meanings not only for its association with orgasm but also for the timing to ejaculate in the context of sexual activity. Spontaneous (involuntary) ejaculation (SE) without any sexual stimulation is a distressing symptom. Our understanding of SE is limited. Unfortunately, many physicians are not aware of these cases. OBJECTIVES The objective of this study is to describe the etiopathogenesis, clinical features, diagnosis, and treatment options for SE. METHODS We searched the literature for publications on "SE," "spontaneous emission" or "involuntary ejaculation," and factors influencing SE in the PUBMED/MEDLINE, Scopus, Cochrane Library, EMBASE, PsycINFO, ProQuest, Academic Search Complete database, Google Scholar, and CINAHL databases from inception to August 2020. RESULTS The literature search yielded 36 relevant publications reporting on 43 patients with SE. Attempts to explain the cause of pathologic SE have included 4 etiological groups (spinal cord lesions, psychological causes, rabies, and drug-induced). The underlying mechanisms responsible for induction of SE may include increased adrenergic activity, overactivity in dopaminergic system, decreased serotonergic activity, damage of descending inhibitory pathway, or penile hyperexcitability. SE may occur in the absence of an identifiable trigger or may be triggered by non-sexual circumstances (micturition, defecation, glans touch, anxiety, panic attack, or school examinations). Treatment options include psychoanalytic treatment, paroxetine, citalopram, sertraline, silodosin, and anxiolytics. In drug-induced SE, dose reduction and drug withdrawal with or without switching to another drug may relief SE. CONCLUSIONS SE is one of the least reported ejaculatory dysfunction. The key feature shared in common by these men is SE without any sexual thoughts or fantasies, may be triggered by non-sexual contexts, rarely associated with orgasm or erection. Treatment by psychoanalytic treatment and pharmacotherapy may be helpful. Further research might explore the definite underlying mechanisms. Abdel-Hamid IA, Ali OI.

Abstract
STUDY DESIGN Observational study (Ethics Committee Number 973.648). OBJECTIVE Evaluating the social and clinical factors associated with sexual dysfunction in men with traumatic spinal cord injury, as well as predictive factors for sexual dysfunction. SUMMARY OF BACKGROUND DATA Besides the motor and sensory loss, sexual function changes after spinal cord injury, ranging from decreased sexual desire to erectile disorders, orgasm, and ejaculation. METHODS Performed with 45 men, with traumatic spinal cord injury and sexually active. Sexual function was assessed by the International Index of Erectile Function and the level and degree of injury were determined following guidelines of International Standards for Neurological and Functional Examination Classification of Spinal Cord Injury. Bi and multivariate analysis was applied, with a 0.05 significance level. RESULTS Forty-five subjects with mean injury time of 7.5 years (CI 5.2-9.9) were evaluated. Having a fixed partner is a protective factor (OR: 0.25; 95% CI: 0.07-0.92) of erectile dysfunction. Sexual desire is associated with the fixed partner (OR: 0.12; 95% CI: 0.02-0.66), masturbation (OR: 0.13; 95% CI: 0.02-0.62), and sexual intercourse in the last month (OR: 0.13; 95% IC: 0.01-0.92). Ejaculation (OR: 0.01; 95% CI: 0.00-0.15) and erectile dysfunction (OR: 15.7; 95% CI: 1.38-178.58) are associated with orgasm. Psychogenic erection (OR: 0.07; 95% CI: 0.01-0.69), monthly frequency of sexual intercourse (OR: 11.3; 95% CI: 2.0-62.8), and orgasmic dysfunction (OR: 7.1; 95% CI: 1.1-44.8) are associated with satisfaction. CONCLUSION Fixed partner, ejaculation, masturbation are protective factors for sexual dysfunction. Erectile dysfunction, orgasmic, and infrequent sex dysfunction are predictors of sexual dysfunction.

Improving Sexual Function by Using Focal Vibrations in Men with Spinal Cord Injury: Encouraging Findings from a Feasibility Study. J Clin Med 2019; 8:E658.

Abstract
Erectile dysfunction (ED) is a frequent and disabling condition in patients with spinal cord injury (SCI). Spasticity can negatively affect sexual intercourse, as it may interfere with positioning, mobility, and muscle activation and strength, leading to ED. The aim of our study was to evaluate the feasibility and efficacy of muscle vibration (MV) applied to the pelvic muscles in improving ED in men with SCI. Ten adult men with traumatic SCI were submitted to 15 sessions of MV, applied on the perineum and the suprapubic and sacrococcygeal areas, using a pneumatic vibrator. MV was performed three times a week for five consecutive weeks, each session lasting 30 min. Muscle tone and sexual function were assessed before and after MV using the Modified Ashworth Scale (MAS) and International Index of Erectile Function (IIEF). We assessed the cremasteric and bulbocavernosus reflexes, as well as the electrophysiological bulbocavernosus reflex (eBCR) and pudendal nerve somatosensory-evoked potential (PSEP). MV was safe and well tolerated. All the patients reported an improvement in MAS and IIEF, with better reflexive responses, and a significant increase in eBCR and PSEP amplitude. In conclusion, MV of the pelvic floor is a promising method to reduce segmental spasticity and improve ED in men with incomplete SCI. However, our findings require confirmation through a randomized clinical trial with a larger sample size and longer trial period to examine long-term after effects.

Abstract
OBJECTIVE To assess the quality of sexual life reported by spinal cord-injured men treated with oral drugs for erectile dysfunction (ED) and their female partners. MATERIAL AND METHOD Men with spinal cord injuries (SCI) complaining of ED and their female partners were evaluated using the Sexual Life Quality Questionnaire (SLQQ), a fully validated instrument in Spain. Two studies were conducted. A transversal study (1) on patients who were already on treatment with phosphodiesterase type 5 inhibitors (PDE5Is) and their partners, with 73 couples providing valid data. An additional prospective study (2) assessed SCI patients naive to PDE5Is in which both the patients and their spouses answered the SLQQ before treatment and after 3 months taking PDE5Is regularly, with 12 couples completing the study. RESULTS The SLQQ scores of SC injured men on PDE5Is (study 1) were under the remembered pre-lesion level, with lower scores reported by those with complete lesions (P<.2 vs incomplete). Their partners' SLQQ scores were apparently similar to pre-injury times. The SLQQ scores of the patients and their partners were well correlated (r = 0.57, P<.0001), and they both reported high treatment satisfaction. Study 2: Untreated SCI patients reported very low SLQQ scores that were improved by PDE5Is treatment (P<.004), albeit without reaching the pre-injury level. A similar trend was found in their partners. Again both patients and partners reported high treatment satisfaction scores (P <.001). CONCLUSION The sexual life quality levels of SC injured men on PDE5Is and their able-bodied spouses are well correlated. Both partners report high treatment satisfaction scores.

Abstract
SUMMARY – The aim of the review is to establish sexual and reproductive functions in men with spinal cord lesion (SCL). Many sexual and reproductive dysfunctions may be found in these patients including individual’s low self-esteem, delay of orgasm, erectile or ejaculatory disorder and abnormalities of semen, which are characterized by lower sperm motility or viability. Owing to improvements in physical medicine and rehabilitation, the focus has been shifted from keeping patients alive towards ensuring the quality of life and improvements of sexual dysfunctions and later reproduction. Erectile dysfunction can be treated by using phosphodiesterase-5 inhibitors, intracavernosal injections, vacuum devices and penile prostheses. Semen can be retrieved from anejaculatory patients by medically assisted methods utilizing penile vibratory stimulation, electroejaculation, prostate massage, or surgically. Although there is low chance for pregnancy in natural way in most of SCL patients, fatherhood is possible through the introduction of assisted medical management. By use of various medical, technical and surgical procedures for sperm retrieval combined with assisted reproductive methods, high pregnancy rates have been reported comparable to those in able-bodied subfertile patients. Nevertheless, future studies are needed to improve semen quality and methods of assisted ejaculation in patients with SCL.

Abstract
Vibration, as provided by a genital vibrator, is commonly regarded as a tool to enhance sexual pleasure and in modern day society falls under the category of a sex toy. However, the vibrator was not originally intended to be a toy, and its benefits reach far beyond that of a plaything. This article is a narrative review of the current evidence regarding the use of vibratory stimulation for the treatment of sexual dysfunction and/or sexual and relationship enhancement. The literature indicates that vibratory stimulation has evidence-based support for the treatment of erectile dysfunction, ejaculatory dysfunction and anorgasmia. Vibratory stimulation is positively correlated with increased sexual desire and overall sexual function. It has also shown benefit for sexual arousal difficulties and pelvic floor dysfunction. Though definitive evidence is lacking, genital vibration is a potential treatment for sexual dysfunction related to a wide variety of sexual health concerns in men and women.

Abstract
INTRODUCTION Spinal Cord Injury (SCI) affects sexual response based on the level and degree of completeness of injury. By using the International Standards for the Neurologic Classification of SCI in conjunction with lumbo-sacral reflexes these effects can be predicted. The International Standards for the Assessment of Autonomic Function after SCI (ISAFSCI) document the impact of SCI on sexual responses including psychogenic and reflex arousal (erection or lubrication), orgasm, ejaculation, and sensation of menses. Responses are described based upon a 0 to 2 scale with 0 being absent, 1 altered, and 2 normal response. Additionally, the lesion is described as supraconal, conal or infraconal. CASE PRESENTATION We present 4 representative cases of the impact of SCI on sexual responses and course of treatment. Case 1 describes a complete supraconal lesion above T6 with upper motor neuron syndrome. Case 2 describes a supraconal complete lesion including the T11-L2 segment. Case 3 describes an infraconal (cauda equina) lesion with lower motor neuron syndrome. Case 4 is theoretical and describes a supraconal lesion above T6 with upper motor neuron syndrome, partial sensation in T11-L2 dermatomes, and other medical comorbidities. DISCUSSION Neurologic examination combined with reflex testing allows prediction of sexual responses after SCI. It would be useful for version 2.0 of the ISAFSCI to assist clinicians in determining the anticipated changes, whether their patients are functioning as anticipated sexually after SCI or whether other concerns also require treatment.

Abstract
We recently defined genetic traits that distinguish sympathetic from parasympathetic neurons, both preganglionic and ganglionic (Espinosa-Medina et al., Science 354:893–897, 2016). By this set of criteria, we found that the sacral autonomic outflow is sympathetic, not parasympathetic as has been thought for more than a century. Proposing such a belated shift in perspective begs the question why the new criterion (cell types defined by their genetic make-up and dependencies) should be favored over the anatomical, physiological and pharmacological considerations of long ago that inspired the “parasympathetic” classification. After a brief reminder of the former, we expound the weaknesses of the latter and argue that the novel genetic definition helps integrating neglected anatomical and physiological observations and clearing the path for future research.

Abstract
Most men with spinal cord injury (SCI) are infertile due to a combination of erectile dysfunction, ejaculatory dysfunction, and abnormal semen quality. This article addresses issues that should be considered when managing the reproductive health of men with SCI. The authors present recommendations based on their decades of experience in managing the reproductive health of more than 1,000 men with SCI. Men with SCI face obstacles when pursuing sexual activity and/or biologic fatherhood. Hypogonadism and premature symptoms of aging may interfere with sexual function. Erectile dysfunction is prevalent in the SCI population, and treatments for erectile dysfunction in the general population are also effective in the SCI population. Most men with SCI cannot ejaculate with sexual intercourse. The procedures of penile vibratory stimulation (PVS) and/or electroejaculation (EEJ) are effective in obtaining an ejaculate from 97% of men with SCI. The ejaculate often contains sufficient total motile sperm to consider the assisted conception procedures of intrauterine insemination or even intravaginal insemination at home. If PVS and/or EEJ fail, sperm may be retrieved surgically from the testis or epididymis. Surgical sperm retrieval typically yields enough motile sperm only for in vitro fertilization with intracytoplasmic sperm injection. The majority of new cases of SCI occur in young men at the peak of their reproductive health. With proper medical management, these men can expect to experience active sexual lives and biologic fatherhood, if these are their goals. Numerous tools are available to physicians for helping these patients reach their goals.

Abstract
Young men comprise the overwhelming majority of men with spinal cord injury (SCI), the incidence of which has been growing over the years. Due to advances in physical medicine and rehabilitation, remarkable improvements in survival rates have been reported, leading to life expectancies similar to those of the general population. However, many sexual and reproductive functions may be impaired due to erectile or ejaculatory dysfunction and semen abnormalities, characterised by low-sperm motility or viability in SCI males who have not become parents yet. Nevertheless, fatherhood is still possible through the introduction of specialised medical management, by using various medical, technical and surgical methods for sperm retrieval in combination with assisted reproductive techniques. Erectile dysfunction can be managed by the use of phosphodiesterase-5 inhibitors, intracavernosal injections, vacuum devices and penile prostheses. Semen can be obtained from the vast majority of anejaculatory men by medically assisted ejaculation through the use of penile vibratory stimulation or electroejaculation and via prostate massage or surgical procedures. Despite impaired sperm parameters, reasonable pregnancy rates similar to those in able-bodied subfertile cohorts have been reported. However, future research should focus on the optimisation of semen quality in these men and on improving natural ejaculation.

Abstract
Objective To review contemporary knowledge concerning the innovative trends and perspectives in the treatment of erectile dysfunction (ED). Methods Medline was reviewed for English-language journal articles between January 2000 and March 2016, using the terms ‘erectile dysfunction treatments’, ‘new trends’ and ‘perspectives’. In all, 114 original articles and 16 review articles were found to be relevant. Of the 76 cited papers that met the inclusion criteria, 51 papers had level of evidence of 1a–2b, whilst 25 had level of evidence of 3–4. Criteria included all pertinent review articles, randomised controlled trials with tight methodological design, cohort studies, and retrospective analyses. We also manually reviewed references from selected articles. Results Several interesting studies have addressed novel phosphodiesterase type 5 inhibitors (PDE5Is), orodispersible tablets, their recent chronic use, and combination with other agents. A few controlled studies have addressed herbal medicine as a sole or additional treatment for ED. Experimental studies and exciting review papers have addressed stem cells as novel players in the field of ED treatment. Other recent articles have revised the current status of low-intensity extracorporeal shockwave therapy in the field of ED. A few articles without long-term data have addressed new technologies that included: external penile support devices, penile vibrators, tissue engineering, nanotechnology, and endovascular tools for ED treatment. Conclusions The current treatment of ED is still far from ideal. We expect to see new drugs and technologies that may revolutionise ED treatment, especially in complex cases.

Abstract
Though the public consciousness is typically focused on factors such as psychology, penis size, and the presence of the "G-spot," there are other anatomical and neuro-anatomic differences that could play an equal, or more important, role in the frequency and intensity of orgasms. Discovering these variations could direct further medical or procedural management to improve sexual satisfaction. The aim of this study is to review the available literature of anatomical sexual variation and to explain why this variation may predispose some patients toward a particular sexual experience. In this review, we explored the available literature on sexual anatomy and neuro-anatomy. We used PubMed and OVID Medline for search terms, including orgasm, penile size variation, clitoral variation, Grafenberg spot, and benefits of orgasm. First we review the basic anatomy and innervation of the reproductive organs. Then we describe several anatomical variations that likely play a superior role to popular known variation (penis size, presence of g-spot, etc). For males, the delicate play between the parasympathetic and sympathetic nervous systems is vital to achieve orgasm. For females, the autonomic component is more complex. The clitoris is the primary anatomical feature for female orgasm, including its migration toward the anterior vaginal wall. In conclusions, orgasms are complex phenomena involving psychological, physiological, and anatomic variation. While these variations predispose people to certain sexual function, future research should explore how to surgically or medically alter these. Clin.

Abstract
Spinal cord injury (SCI) occurs most often in young men at the peak of their reproductive health. The majority of men with SCI cannot father children naturally. Three major complications contribute to infertility in men with SCI: erectile dysfunction, ejaculatory dysfunction, and abnormal semen quality. Erectile dysfunction can be managed by regimens available to the general population, including oral administration of phosphodiesterase-5 (PDE-5) inhibitors, intracavernosal injections, vacuum devices, and penile prostheses. Semen may be obtained from anejaculatory men with SCI via the medically assisted ejaculation methods of penile vibratory stimulation (PVS) or electroejaculation (EEJ). Sperm retrieval is also possible via prostate massage or surgical sperm retrieval. Most men with SCI have abnormal semen quality characterized by normal sperm concentrations but abnormally low sperm motility and viability. Accessory gland dysfunction has been proposed as the cause of these abnormalities. Leukocytospermia is evident in most SCI patients. Additionally, elevated concentrations of pro-inflammatory cytokines and elevated concentrations of inflammasome components are found in their semen. Neutralization of these constituents has resulted in improved sperm motility. There is a recent and alarming trend in the management of infertility in couples with SCI male partners. Although many men with SCI have sufficient motile sperm in their ejaculates for attempting intrauterine insemination (IUI) or even intravaginal insemination, surgical sperm retrieval is often introduced as the first and only sperm retrieval method for these couples. Surgical sperm retrieval commits the couple to the most advanced, expensive, and invasive method of assisted conception: in vitro fertilization with intracytoplasmic sperm injection (IVF/ICSI). Couples should be informed of all options, including semen retrieval by PVS or EEJ. Intravaginal insemination or IUI should be considered when indicated.

Abstract
INTRODUCTION One of the methods to treat post radical prostatectomy stress urinary incontinence is the AdVance (American Medical Systems, Minnetonka, MN, USA) male sling procedure. During this procedure, the somatic innervation of the penis may be at risk for injury. Six AdVance procedures were performed in six donated bodies at the Anatomy and Embryology Department of the Leiden University Medical Centre. The pelves were dissected and the shortest distance between the sling and the dorsal nerve of the penis (DNP) was documented. AIM The aim of this study was to describe the anatomical relation between the AdVance male sling and penile nerves based on the dissection of six adult male pelves. METHODS The AdVance male sling procedure was conducted in six donated male bodies. After placement, the pelves were dissected and the shortest distance between sling and the DNP was documented. MAIN OUTCOME MEASURE The main outcome measure was the distance between the AdVance male sling and the DNP. RESULTS The mean distance of the sling to the DNP was 4.1 mm and was found situated directly next to the nerve (distance 0 mm) in 4 out of 12 (33%) hemipelves. The distance of the sling to the obturator neurovascular bundle was 30 mm or more in all six bodies. CONCLUSIONS Damage to the DNP caused by the AdVance male sling procedure appears to be an extremely rare complication, which has not been described in current literature. The proximity of the AdVance to the DNP could, however, pose a risk that should be taken into consideration by physicians and patients when opting for surgery.

Abstract
Many aspects of sexuality can be disrupted following a spinal cord lesion (SCL). It can alter an individual's self-esteem and body image, interfere with positioning and mobility, introduce unexpected problems with incontinence and spasticity, decrease pleasure, and delay orgasm. Sexual concerns in men can involve erectile function, essential for intercourse, ejaculation function, necessary for fertility, and the ability to reach orgasm. In women they can involve concerns with vaginal lubrication, genital congestion, and vaginal infections, which can all go unnoticed, and orgasm, which may be lost. All of these concerns must be addressed during rehabilitation as individuals with SCL continue to live an active sexual life, and consider sexuality among their top priority for quality of life. This chapter describes the impact of SCL on various phases of men's and women's sexual responses and on various aspects of sexuality. Treatments are described in terms of what is currently available and what is specific to the SCL population. New approaches in particular for women are described, along with tips from sexual counseling which consider an overall approach, taking into account the primary, secondary, and tertiary consequences of the SCL on the individual's sexuality. Throughout the chapter, attempts are made to integrate neurophysiologic knowledge, findings from the literature on SCL, and clinical experience in sexual rehabilitation.

Abstract
New discoveries and technological advances in medicine are rapid. The role of technology in the treatment of erectile dysfunction (ED) will be widened and more options will be available in the years to come. These erectile technologies include external penile support devices, penile vibrators, low intensity extracorporeal shockwave, tissue engineering, nanotechnology and endovascular technology. Even for matured treatment modalities for ED, such as vacuum erectile devices and penile implants, there is new scientific information and novel technology available to improve their usage and to stimulate new ideas. We anticipate that erectile technologies may revolutionize ED treatment and in the very near future ED may become a curable condition.

Abstract
Introdução Entre as consequências da lesão medular (LM), está o deficit na função sexual, o que interfere na qualidade de vida do indivíduo. Objetivos Conhecer e descrever o perfil da sexualidade de homens com LM, comparando os períodos pré e pós-lesão. Materiais e métodos Estudo transversal com 36 homens com LM. Os dados foram coletados através de um questionário (QSH-LM) e um roteiro. As variáveis quantitativas foram apresentadas por média e desvio padrão. As variáveis categóricas foram apresentadas por frequências absolutas e relativas e as associações foram realizadas através do teste Qui-quadrado. Todos os testes apresentaram significância de 5%. Resultados Houve prevalência de pacientes paraplégicos e de lesões do tipo completa. A prática, frequência, desejo e satisfação sexual decaíram após a LM, assim como as respostas sexuais. Dentre essas estão ereção, ejaculação e orgasmo, que decaíram de forma relevante após a LM. A sensação mais relatada durante o ato sexual foi o aumento da resposta cardiorrespiratória, antes ou após a LM, e mais indivíduos passaram a sentir nenhuma sensação durante a atividade sexual após a LM. Houve significativa associação entre tipo de lesão e presença de orgasmo e entre prática e satisfação sexual após a LM. Conclusão Foi observado que a resposta sexual após a LM altera na ordem crescente: ereção, orgasmo e ejaculação. Percebe-se que muitas vezes a reabilitação é focada nas capacidades motoras e a sexualidade é pouco abordada.

Abstract
Male sexual response is controlled by a series of neurally mediated phenomena regulating libido, motivation, arousal and genital responses such as penile erection and ejaculation. These neural events that occur in a hormonally defined milieu involve different neurophysiological, neurochemical, and neuropsychological parameters controlled by central mechanisms, spinal reflexes and peripheral nervous system. Epidemiologic studies have suggested the high prevalence of male sexual dysfunction worldwide with significant impact on the quality of life of patients suffering from this problem. The incidence of sexual dysfunction is particularly high among men with neurologic disorders. Sexual dysfunction in men, such as loss of sexual desire, erectile dysfunction (ED), changes in arousal, and disturbances in orgasm and ejaculation may involve organic causes, psychological problems, or both. Organic male sexual disorders include a wide variety of neurologic, vasculogenic, neurovascular or hormonal factors that interfere with libido, erection, ejaculation and orgasm. Neurogenic sexual dysfunction may result from a specific neurologic problem or it could be the presenting symptom of a developing neurologic disease. Neurologic ED could result from complications of chronic neurologic disorders, trauma, surgical injury or iatrogenic causes. These etiologic factors and the underlying pathophysiologic conditions could overlap, which should be considered when making a diagnosis and selecting a treatment. A detailed history of physical examination, neurologic disorders, as well as any past history of psychological and psychiatric disturbances, and a thorough neurological examination will provide better understanding of the underlying causes of neurogenic sexual dysfunction. In patients with spinal cord injury, the location of the lesion and the time of onset of injury should be determined. Therapeutic strategies against erectile dysfunction are initiated with the least invasive options using the phosphodiesterase inhibitors. When oral medication options are exhausted, intraurethral and intracavernosal therapies and ultimately vacuum constriction devices and penile implants are considered. Recent basic research has suggested the potential role of stem cell-based therapeutic strategies to protect penile neural integrity and reverse cavernosal neurodegeneration in experimental models. Further insight into the central, spinal and peripheral neural mechanisms of male sexual response may help precise diagnosis and better management of neurogenic sexual dysfunction in men.

Abstract
Sex is a fundamental pleasure, and crucial to the survival of our species. Though not many people would disagree with the proposition that sexual behaviour depends on the brain, the neuroscientific study of human sex is still relatively taboo and much remains to be discovered. On the contrary, excellent experimental animal models (mostly rat) are available that have uncovered major behavioural, neurochemical, and neuroanatomical characteristics of sexual behaviour. Restructuring sexual behaviour into broader terms reflecting behavioural states (wanting, liking, and inhibition) facilitates species comparison, revealing many similarities between animal and human sexual pleasure cycles, some of which can serve as potential avenues of new human sex research. In particular, behavioural and brain evidence clearly shows that motivational and consummatory phases are fundamentally distinct, and that genitally-induced sexual reward is a major factor in sexual learning mechanisms.

Abstract
BACKGROUND We like to think about sexual activity as something fixed, basic and primal. However, this does not seem to fully capture reality. Even when we relish sex, we may be capable of mentalizing, talking, voluntarily postponing orgasm, and much more. This might indicate that the central control mechanisms of sexual activity are quite flexible and susceptible to learning mechanisms, and that cortical brain areas play a critical part. OBJECTIVE This study aimed to identify those cortical areas and mechanisms most consistently implicated in sexual activity. DESIGN A comprehensive review of the human functional neuroimaging literature on sexual activity, i.e. genital stimulation and orgasm, is made. RESULTS Genital stimulation recruits the classical somatosensory matrix, but also areas far beyond that. The posterior insula may be particularly important for processing input from the engorged penis and coordinating penile responses. Extrastriate visual cortex tracks sexual arousal and responds to genital stimulation even when subjects have their eyes closed. The ventromedial prefrontal cortex is also tightly coupled to sexual arousal, but low activity in this area predicts high sexual arousal. CONCLUSION This review has indicated cortical sites where activity is moderated by tactile genital inflow and high sexual arousal. Behavioral implications are discussed and where possible the relevance for learning mechanisms is indicated. Overall, it is clear that the cerebral cortex has something to say about sexual activity.
