Sexual dysfunction and infertility in the male spina bifida patient

Patient Characteristics Associated with Sexual Interest and Activity Among Adults with Spina Bifida

OBJECTIVE

To identify factors associated with sexual interest and activity among adults with spina bifida and to describe the sexual profile of those who were sexually active. Sexual health of adults with spina bifida is often neglected and current knowledge on the topic is limited.

METHODS

An anonymous web-based survey was advertised and administered between March 2018 and September 2018 and participants 16 years and older with spina bifida were included in this study. Respondents were asked about sexual interest, activity, and function using the validated Patient-Reported Outcomes Measurement Information System Sexual Function Profile. Bivariate and multivariable models with ordinal logistic regression were fitted to evaluate predictors of sexual interest and sexual function.

RESULTS

Of the 261 respondents with a self-reported diagnosis of spina bifida (mean age of 38.5 years), 73.2% noted at least a little bit of interest in sexual activity. In multivariate analysis, women were less likely to report higher sexual interest than men (odds ratio (OR) = 0.53, 95% CI 0.31-0.92, P = .03) whereas those with higher physical functioning were more likely to have higher sexual interest (OR = 1.04, confidence interval (CI) 1.01-1.07, P = .03). Just less than half of respondents (46.4%) were sexually active in the past 30 days, and those with a ventriculoperitoneal shunt were less likely to engage in sexual activity compared to those without (OR = 0.36, 95% CI 0.19-0.68; P <.01).

CONCLUSION

The mismatch between sexual interest and sexual activity highlights the importance of exploring issues related to sexual health when counseling adult patients with spina bifida.

What has changed in pediatric neurosurgical care in spina bifida? A 30-year UAB/Children's of Alabama observational overview

Spina bifida (SB) remains the most serious and most common congenital anomaly of the human nervous system that is compatible with life. The open myelomeningocele on the back is perhaps the most obvious initial problem, but the collective impact of dysraphism upon the entirety of the nervous system and innervated organs is an equal or greater longitudinal threat. As such, patients with myelomeningocele (MMC) are best managed in a multi-disciplinary clinic that brings together experienced medical, nursing, and therapy teams that provide high standards of care while studying outcomes and sharing insights and experiences. Since its inception 30 years ago, the spina bifida program at UAB/Children's of Alabama has remained dedicated to providing exemplary multi-disciplinary care for affected children and their families. During this time, there has been great change in the care landscape, but many of the neurosurgical principles and primary issues have remained the same. In utero myelomeningocele closure (IUMC) has revolutionized initial care and has favorable impact on several important co-morbidities of SB including hydrocephalus, the Chiari II malformation, and the functional level of the neurologic deficit. Hydrocephalus however is not solved by IUMC, and hydrocephalus management remains at the center of neurosurgical care in SB. Ventricular shunts were long the cornerstone of treatment for hydrocephalus, but we came to assess and incorporate endoscopic third ventriculostomy with choroid plexus coagulation (ETV-CPC). Educated and nurtured by an experienced senior mentor, we dedicated ourselves to fundamental concepts but persistently evaluated our care outcomes and evolved our protocols and paradigms for improvement. Active conversations amidst networks of treasured colleagues were central to this development and growth. While hydrocephalus support and treatment of tethered spinal cord remained our principal neurosurgical charges, we evolved to embrace a holistic perspective and approach that is reflected and captured in the Lifetime Care Plan. Our team engaged actively in important workshops and guideline initiatives and was central to the development and support of the National Spina Bifida Patient Registry. We started and developed an adult SB clinic to support our patients who aged out of pediatric care. Lessons there taught us the importance of a model of transition that emphasized personal responsibility and awareness of health and the crucial role of dedicated support over time. Support for sleep, bowel health, and personal intimate cares are important contributors to overall health and care. This paper details our growth, learning, and evolution of care provision over the past 30 years.

Dynamic volumetric imaging and cilia beat mapping in the mouse male reproductive tract with optical coherence tomography

Spermatozoa transport within the male reproductive tract is a highly dynamic and biologically important reproductive event. However, due to the lack of live volumetric imaging technologies and quantitative measurements, there is little information on the dynamic aspect and regulation of this process. Here, we presented ex vivo dynamic volumetric imaging of the mouse testis, efferent duct, epididymis, and vas deferens at a micro-scale spatial resolution with optical coherence tomography (OCT). Micro computed tomography imaging is presented as a reference for the proposed OCT imaging. Application of functional OCT analysis allowed for 3D mapping of the cilia beat frequency in the efferent duct, which volumetrically visualized the spatial distribution of the ciliated cells and corresponding ciliary activities. Potentially these analyses could be expanded to in vivo settings through intravital approach. In summary, this study demonstrated that OCT has a great potential to investigate the microstructure and dynamics, such as cilia beating, muscle contractions, and sperm transport, within the male reproductive tract.

Antenatal counselling for prospective parents whose fetus has a neurological anomaly: part 2, risks of adverse outcome in common anomalies

After diagnosis of a fetal neurological anomaly, prospective parents want to know the best and worst-case scenarios and an estimation of the risk to their infant of having an atypical developmental outcome. The literature on developmental outcomes for fetal neurological anomalies is poor: studies are characterized by retrospective design, small sample size, often no standardized assessment of development, and differing definitions of anomalies. This review provides an aide-memoir on the risks of adverse neurodevelopmental outcome for ventriculomegaly, cortical anomalies, microcephaly, macrocephaly, agenesis of the corpus callosum, posterior fossa anomalies, and myelomeningocele, to assist healthcare professionals in counselling. The data in this review should be used alongside recommendations on counselling and service design described in part 1 to provide antenatal counselling.

Promoting Healthy Sexuality for Children and Adolescents With Disabilities

This clinical report updates a 2006 report from the American Academy of Pediatrics titled "Sexuality of Children and Adolescents With Developmental Disabilities." The development of a healthy sexuality best occurs through appropriate education, absence of coercion and violence, and developmental acquisition of skills to navigate feelings, desires, relationships, and social pressures. Pediatric health care providers are important resources for anticipatory guidance and education for all children and youth as they understand their changing bodies, feelings, and behaviors. Yet, youth with disabilities and their families report inadequate education and guidance from pediatricians regarding sexual health development. In the decade since the original clinical report was published, there have been many advancements in the understanding and care of children and youth with disabilities, in part because of an increased prevalence and breadth of autism spectrum disorder as well as an increased longevity of individuals with medically complex and severely disabling conditions. During this same time frame, sexual education in US public schools has diminished, and there is emerging evidence that the attitudes and beliefs of all youth (with and without disability) about sex and sexuality are being formed through media rather than formal education or parent and/or health care provider sources. This report aims to provide the pediatric health care provider with resources and tools for clinical practice to address the sexual development of children and youth with disabilities. The report emphasizes strategies to promote competence in achieving a healthy sexuality regardless of physical, cognitive, or socioemotional limitations.

Canary in the Coal Mine? Male Infertility as a Marker of Overall Health

Male factor infertility is a common problem. Evidence is emerging regarding the spectrum of systemic disease and illness harbored by infertile men who otherwise appear healthy. In this review, we present evidence that infertile men have poor overall health and increased morbidity and mortality, increased rates of both genitourinary and non-genitourinary malignancy, and greater risks of systemic disease. The review also highlights numerous genetic conditions associated with male infertility as well as emerging translational evidence of genitourinary birth defects and their impact on male infertility. Finally, parallels to the overall health of infertile women are presented. This review highlights the importance of a comprehensive health evaluation of men who present for an infertility assessment.

Altered sacral neural crest development in Pax3 spina bifida mutants underlies deficits of bladder innervation and function

Mouse models of Spina bifida (SB) have been instrumental for identifying genes, developmental processes, and environmental factors that influence neurulation and neural tube closure. Beyond the prominent neural tube defects, other aspects of the nervous system can be affected in SB with significant changes in essential bodily functions such as urination. SB patients frequently experience bladder dysfunction and SB fetuses exhibit reduced density of bladder nerves and smooth muscle although the developmental origins of these deficits have not been determined. The Pax3 Splotch-delayed (Pax3^Sp-d) mouse model of SB is one of a very few mouse SB models that survives to late stages of gestation. Through analysis of Pax3^Sp-d mutants we sought to define how altered bladder innervation in SB might arise by tracing sacral neural crest (NC) development, pelvic ganglia neuronal differentiation, and assessing bladder nerve fiber density. In Pax3^Sp-d/Sp-d fetal mice we observed delayed migration of Sox10+ NC-derived progenitors (NCPs), deficient pelvic ganglia neurogenesis, and reduced density of bladder wall innervation. We further combined NC-specific deletion of Pax3 with the constitutive Pax3^Sp-d allele in an effort to generate viable Pax3 mutants to examine later stages of bladder innervation and postnatal bladder function. Neural crest specific deletion of a Pax3 flox allele, using a Sox10-cre driver, in combination with a constitutive Pax3^Sp-d mutation produced postnatal viable offspring that exhibited altered bladder function as well as reduced bladder wall innervation and altered connectivity between accessory ganglia at the bladder neck. Combined, the results show that Pax3 plays critical roles within sacral NC that are essential for initiation of neurogenesis and differentiation of autonomic neurons within pelvic ganglia.

Perspectives on urological care in spina bifida patients

Spina bifida (SB) is a neurogenetic disorder with a complex etiology that involves genetic and environmental factors. SB can occur in two major forms of open SB or SB aperta and closed SB or SB occulta. Myelomeningocele (MMC), the most common neural tube defects (NTDs), occurs in approximately 1 in 1,000 births. Considering non-genetic factors, diminished folate status is the best-known factor influencing NTD risk. The methylenetetrahydrofolate reductase (MTHFR) gene has been implicated as a risk factor for NTDs. The primary disorder in the pathogenesis of MMC is failed neural tube closure in the embryonic spinal region. The clinical manifestation of SB depends on clinical type and severity. SB can be detected in the second trimester using ultrasound which will reveal specific cranial signs. The management of MMC traditionally involves surgery within 48 h of birth. Prenatal repair of MMC is recommended for fetuses who meet maternal and fetal Management of Myelomeningocele Study (MOMS) specified criteria. Urological manifestations of SB include urinary incontinence, urolithiasis, sexual dysfunction, renal dysfunction, and urinary tract infection. Renal failure is among the most severe complications of SB. The most important role of the urologist is the management of neurogenic bladder. Medical management with clean intermittent catheterization and anticholinergic treatment is generally considered the gold standard of therapy. However, when this therapy fails surgical reconstruction become the only remaining option. This review will summarize the pathogenesis, risk factors, genetic contribution, diagnostic test, and management of SB. Lastly, the urologic outcomes and therapies are reviewed.

Sexual function in adult patients who have undergone augmentation surgery in childhood: what is really important?

Problems relating to the development of a healthy approach to sex and intimacy during puberty, after augmentation cystoplasty, are scarcely discussed in literature. Therefore, this may suggest that such issues are insufficiently addressed by pediatric urologists. We gathered four experts in the field as well as an experienced leader of a patient group and mother of a girl with spina bifida and asked questions relevant to the following areas of care: (a) diversion, urinary incontinence, and sexual life; (b) impact of a stoma on body image perception and self-esteem; (c) specific female concerns with regard to fertility and recurrent urinary infections; (d) specific male concerns on anejaculation and erectile dysfunction. Their answers are discussed in view of the available literature. All experts and the patient group representative agreed that most of these patients will experience: lack of self-confidence as the most frequent obstacle to starting a relationship and incontinence as a barrier to sexual activity. The cosmesis of the stoma and abdominal scars might influence self-esteem and therefore the sexual activity, however it appears to be a less common concern in males than females. Our results outline the importance and influence that the body image, self-esteem, and confidence present for the individual expectations of the patients related to sex life and sexual activity. Physicians should be encouraged to ask all postpubertal patients about their sexual concerns at every visit. Further studies and exchange of information between clinicians are needed to provide meaningful and analyzable patient-related outcome measures (PROMs).

A Japanese man with spina bifida who successfully fathered a child following fertility treatment

INTRODUCTION

Spina bifida is a congenital anomaly caused by a neural tube closure defect that may result in sexual dysfunction. Sexual dysfunction and infertility are prevalent in spina bifida patients but have been scarcely reported.

CASE PRESENTATION

We report the case of a 36-year-old man with spina bifida and mild-moderate erectile dysfunction. He could experience erection and ejaculation. He got married at the age of 28 years, but his wife was unable to conceive for 2 years thereafter. Semen analyses revealed that semen volume, sperm density, and sperm motility rate were below normal levels. It was concluded that natural conception would be difficult, and assisted reproductive strategies were planned. After 4 years, his wife conceived through intracytoplasmic sperm injection and gave birth to a healthy baby.

CONCLUSION

Fertility treatment, including intracytoplasmic sperm injection, is a useful therapeutic method for male patients with spina bifida who desire to father a child.

Fertility and sexuality issues in congenital lifelong urology patients: male aspects

PURPOSE

To review existing literature about fertility and sexuality of boys born with complex congenital genitourinary anomalies.

METHODS

A Pubmed review was performed in December 2018 to identify the most relevant original manuscripts regarding male complex congenital conditions affecting the urogenital system in male patients including spina bifida (SB), bladder exstrophy-epispadias complex (BEEC) and hypospadias. A comprehensive review was drafted exploring sexual dysfunction from a medical, psychosexual, surgical and reproductive point of view during transition from childhood (or adolescence) to adulthood.

RESULTS

About 75% of men with SB have erectile dysfunction (ED) (Gamé et al. in Urology 67(3):566-570, 2006; Diamond et al. in 58(4):434-435, 1986). Most SB patients have impaired sexual development mainly due to diminished self-esteem, dependence on caregivers and lack of privacy (Blum et al. in Pediatrics 88(2):280-285, 1991). Men with BEEC have fewer intimate relationships than women because of the greater difficulties with issues regarding their genitalia and sexual activities (Deans et al. in Am J Obstet Gynecol 206(6):496.e1-496.e6, 2012). However, a good quality of life is achievable with the effective use of coping strategies (Deng et al. in Transl Androl Urol 7:941, 2018; Rikken et al. in BMC Womens Health 18(1):163, 2018; Friedler et al. in Reprod Biomed Online 32(1):54-61, 2016). Chordee occurs in 25% of all hypospadias patients. More severe hypospadias is related to a greater risk for complications. The long-term sexual quality of life (QoL) in men who underwent hypospadias surgery is influenced by a lot of factors. Therefore, an interactive and dynamic biopsychosocial model of sexual QoL was proposed.

CONCLUSIONS

The care of patients with congenital urologic conditions becomes a challenge especially in the period of 'transition'. The goal of follow-up is a holistic management viewed from a medical, psychosexual, surgical end reproductive point. All patients should be asked for specific urinary, fecal or sexual concerns.

Sexual health and education guidelines for the care of people with spina bifida

Sexual development is not only comprised of the changes to a person's body during puberty; it is a part of social development and should be considered in the context of basic and routine human desires for connectedness and intimacy, beliefs, values and aspirations. As is true for everyone, it is important that individuals with spina bifida have opportunities to acquire developmentally appropriate, relevant and accurate sexual health knowledge. Those with spina bifida need to be able to negotiate sexual desire, intimacy and sexual expression. They also need education about their sexual health and how to limit the negative outcomes of sexual activity related to sexually transmitted infections, unplanned pregnancy or sexual coercion, violence, abuse or exploitation. This article discusses the Spina Bifida Sexual Health and Education Healthcare Guidelines from the 2018 Spina Bifida Association's Fourth Edition of the Guidelines for the Care of People with Spina Bifida using the World Health Organization's framing of sexual health and reviews the literature on sexual health and education for individuals with spina bifida.
