Measurement of sexual functioning after spinal cord injury: preferred instruments.

Abstract Background/Objective: To determine the utility of certain instruments to assess sexuality and fertility after SCI, an expert panel identified key areas to study and evaluated available instruments. These were rated according to certain predefined criteria. Methods: The authors divided sexual issues into male and female sexual function, male reproductive function, and female reproductive function. The instruments that have been used most frequently to measure these aspects of sexual function over the past 5 years were identified by expert consensus. Finally, these instruments were subjected to a critical review. Results: The Female Sexual Function Index (FSFI), measurement of vaginal pulse amplitude (VPA), the International Index of Erectile Function (IIEF), and the measurement of ejaculatory function and semen quality were considered appropriate measures to assess sexual responses and reproductive function after SCI. There were no measures identified to assess female reproductive function. Conclusions: For clinical trials aiming to improve sexual function after SCI, the FSFI or the IIEF is currently preferred. Although VPA is an appropriate means to assess female sexual responses, it is only useful for laboratory studies and is too invasive for use in clinical trials. For assessment of male fertility potential, assessment of ejaculatory capacity and semen analysis are recommended.

Recommendations for Discussing Sexuality After Spinal Cord Injury/Dysfunction in Children, Adolescents, and Adults

Abstract Background/Objective: To review the literature and provide a framework for sex education for the child, adolescent, or adult with a spinal cord injury (SCI) or disorder. Methods: Discussion and review of the literature. Results: There is a paucity of research available regarding the impact of SCis and disorders on sexuality in children and adolescents; however, there is a significant body of literature on this topic in adults. Recommendations based on these findings are presented. Guidelines regarding sexuality in children and adolescents with general disabilities may be adapted for the education of children and adolescents with SCis and disorders. Conclusions: Parents, partners, and persons with SCis and disorders should be provided with ageappropriate information about sexuality that includes specific information with respect to SCis and disorders. Although there has been a significant increase in information that is available about the impact of sexuality in adults after SCI, more information is needed about the effects of SCis and disorders on the healthy sexual development of children and adolescents.

Development of international standards to document sexual and reproductive functions after spinal cord injury: Preliminary report

Clinicians need standard terminology to communicate effectively about remaining autonomic function in persons after spinal cord injury. This article illustrates the development of standard nomenclature that describes the impact of injury on sexual functioning. A standard anatomic diagnosis and a secondary means of describing the presence of male and female sexual dysfunction, genital arousal, and orgasmic function are discussed.

fMRI Localization of Spinal Cord Processing Underlying Female Sexual Arousal

Using functional magnetic resonance imaging, the authors aimed to determine the roles of the human spinal cord in mediating sexual responses in women. Functional magnetic resonance imaging of the entire lower thoracic, lumbar, and sacral spinal cord was performed using a sexual stimulation paradigm designed to elicit psychological and physical components of sexual arousal. Responses were measured in 9 healthy adult women during 3 consecutive conditions: (a) erotic audiovisual, (b) manual clitoral, and (c) audiovisual plus manual stimulation. Functional magnetic resonance imaging results in healthy subjects demonstrate that this method is sensitive for mapping sexual function in the spinal cord, and identify several key regions involved in human sexual response, including the intermediolateral cell column, the dorsal commissural nucleus, and the sacral parasympathetic nucleus. Using spinal functional magnetic resonance imaging, this study identified many of the spinal cord regions involved in female sexual responses. Results from audiovisual and manual clitoral stimulation correspond with previous data regarding lumbar and sacral neurologic changes during sexual arousal. This study provides the first characterization of neural activity in the human spinal cord underlying healthy female sexual responses and sets a foundation for future studies aimed at mapping changes that result from sexual dysfunction, spinal cord trauma or disease.

Neural Correlates of Sexual Arousal in the Spinal Cords of Able-Bodied Men: A Spinal fMRI Investigation

The purpose of this study was to determine whether spinal cord functional magnetic resonance imaging could be used to map neural activity throughout the lower thoracic, lumbar, and sacral spinal cord regions during sexual arousal in healthy men. The authors found that viewing erotic films and genital self-stimulation elicited predominantly increased signal, indicative of amplified neuronal input to the dorsal and ventral horns and in the autonomic preganglionic nuclei of the lower thoracic, lumbar, and sacral spinal cord. In addition, linear regression analyses revealed a number of robust correlations (|R| ≥ 0.7) between signal intensity changes in these spinal cord regions and self-reported ratings of mental and physical sexual arousal. Taken together, these results demonstrate that spinal cord functional magnetic resonance imaging is an effective and sensitive technique for mapping the neural correlates of sexual arousal in the spinal cords of able-bodied men. Most important, the results from this study indicate that spinal cord functional magnetic resonance imaging may have important applications as a clinical tool for assessing and mapping the changes that occur in the spinal cords of men suffering from sexual dysfunction as a result of spinal cord trauma.

The neurologic control of arousal and orgasm with specific attention to spinal cord lesions: Integrating preclinical and clinical sciences.

Preclinical research in animal models is important for understanding the neural pathways and pathophysiology underlying changes in sexual function after SCI. In vivo animal models, primarily rodents, have provided valuable information on the central pathways regulating sexual arousal and orgasm; however, further research is required in females and preclinical modeling of SCI that can be better translated to men and women. Translation of the autonomic and somatic regulation of sexual responses from preclinical models through clinical research correlates well with respect to the peripheral-spinal systems involved. However, due to the nature of sexual responses, parallel studies are necessary in animals and humans. Human studies of individuals with SCIs have provided information about the neurologic control of arousal and orgasm. Psychogenic arousal is related to the preservation of sensation at T11-L2 whereas orgasm requires the presence of an intact sacral reflex arc. Studies point to evidence of a spinal pattern generator at L3-5. Because of the exact nature of SCIs, further research using neuroimaging will be beneficial, not only to elucidate the neurological control of sexual responses after SCI, but also in able-bodied individuals. Understanding and ameliorating the effects of SCI on sexual function is important to the well-being and quality of life of individuals with SCIs and their partners, thus future research should focus more on this important topic.

Improving Sexual Satisfaction in Persons with Spinal Cord Injuries: Collective Wisdom

Sexuality is an important part of life, and it is necessary for clinicians to have a specific format in which to address sexual issues with their patients. A systematic approach to working with patients with spinal cord injury (SCI) to improve their sexual functioning and response is presented. Nonjudgmental communication about sexual concerns is followed by a detailed pre- and postinjury medical, psychosocial, and sexual history. If preexisting sexual issues are present, it is recommended that the patient be referred for assessment and treatment of these separate from the patients SCI-related concerns. Physical examination, with special attention to issues that could impact the patients sexuality, is followed by a detailed neurologic assessment with specific attention to the T11-L2 and S3-5 spinal segments. Education of the patient with regard to his or her sexual potential and the need to be flexible in his or her sexual repertoire is followed by self-exploration and practice. Routine follow-up is suggested after patients initial sexual exploration. Treatment of confounding and iatrogenic factors related to SCI is followed by more sexual experience. Afterwards the clinician is encouraged to use simple techniques to treat sexual issues and follow-up with the patient to assess the outcome. A structured program utilizing vibratory stimulation with or without midodrine is described as a way to achieve ejaculation and potentially orgasm, and techniques for treating severe autonomic dysreflexia are discussed. If these interventions do not alleviate the patients sexual concerns, the clinician should refer the patient for more specialized consultation.

Altered spinal cord activity during sexual stimulation in women with SCI: a pilot fMRI study

Introduction:The objective of this study was to assess the feasibility of the use of functional magnetic resonance imaging (fMRI) to evaluate the spinal activation during sexual response of the thoracic, lumbar and sacral spinal cord.Materials and Methods:This is a laboratory-based pilot study in human females at a University-based medical center in the United States. In three healthy spinal cord injury (SCI) females, spinal cord activations during sexual audiovisual stimulation (alone), genital self-stimulation (alone) and simultaneous audiovisual and genital self-stimulation (combined) were assessed and then compared with each subjects’ remaining sensory and motor function.Results:Spinal fMRI responses of the intermediolateral columns were found during audiovisual stimulation in both subjects with incomplete injuries, but they were not observed in the subject with a complete injury. Moreover, sacral responses to combined stimulation differed greatly between the subjects with complete and incomplete injuries.Conclusion:These results not only provide the first in vivo documentation of spinal fMRI responses associated with sexual arousal in women with SCIs, but also suggest that spinal cord fMRI is capable of distinguishing between injury subtypes. Therefore, although there are certain limitations associated with fMRI during sexual stimulation (for example, movement artifacts, an artificially controlled environment and so), these findings demonstrate the potential utility of incorporating spinal cord fMRI in future research to evaluate the impact of specific patterns of SCI on sexual responses and/or the effects of treatment.
