Abstract
PURPOSE OF REVIEW This review article will examine the current literature on hypospadias-related complications in adult patients. RECENT FINDINGS In this article, we will review the most recent studies evaluating hypospadias-related stricture disease, erectile function, fertility, and psychosexual outcomes in adult men with history of hypospadias repair in childhood. Managing hypospadias-related complications in adult patients is challenging to reconstructive urologists due to the compounded complexity of innate tissue deficiency and history of prior surgical repairs. In this review, we explore overall functional outcomes of adults with history of hypospadias repair as well as repair strategies of hypospadias-related urethral stricture disease. We will review erectile function, fertility and psychosexual outcomes as well as potential complications, which often do not surface until late adolescence and adulthood. Although it is challenging to characterize and quantify hypospadias-related complications, further longitudinal study is needed to better care for this complex patient population.

Long-term impact of commonly performed operations in pediatric urology on reproductive and sexual health. Ther Adv Urol 2024; 16:17562872241249083. [PMID: 38736900 PMCID: PMC11085008 DOI: 10.1177/17562872241249083] [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: 10/28/2023] [Accepted: 03/28/2024] [Indexed: 05/14/2024] Open
Abstract
Introduction Sexual dysfunction is highly prevalent among men of reproductive age. Clinical practice guidelines have been established to assist providers in identification and education of patients who are at increased risk for infertility and sexual dysfunction with certain congenital and acquired urogenital disorders. The authors sought to review the reproductive and sexual health implications of treating common childhood urological conditions with commonly performed surgical procedures. Methods To ensure the inclusion of influential and highly regarded research, we prioritized citations from the most-frequently cited articles on our respective review topics. Our inclusion criteria considered studies with substantial sample sizes and rigorously designed methodologies. Several topics were reviewed, including penile chordee, hypospadias, posterior urethral valves, varicoceles, undescended testicles, and testicular torsion. Results For chordee, surgical plication or corporal grafting may be employed. Erectile function remains unaltered post-surgery, while penile length may decrease after repair, which may be avoided using dermal grafts. Hypospadias repair hinges on severity and availability of the urethral plate. Those who underwent hypospadias repair report decreased penile length, but sexual satisfaction, libido, and semen quality are comparable to controls. Posterior urethral valves are usually treated with valve ablation. While valve ablation and bladder neck incision have not been found to affect ejaculatory function, high degree of concurrent renal dysfunction related to nephrogenic and bladder dysfunction may impact semen parameters and erectile function. Regarding varicocele, earlier management has been associated with better long-term fertility outcomes, and surgical intervention is advisable if there is observable testicular atrophy. Earlier repair of undescended testicle with orchiopexy has been found to improve fertility rates as well as decrease malignancy rates. Unilateral orchiectomy for testicular torsion without the ability for salvage has been shown to have decreased semen parameters but unaffected fertility rates. Conclusion Infertility and sexual dysfunction are multivariable entities, with etiologies both congenital and acquired. At the same time, many common pediatric urology surgeries are performed to correct anatomic pathology that may lead to reproductive dysfunction in adulthood. This review highlights the need for diagnosis and management of pediatric urologic conditions as these conditions may impact long-term sexual function post-operatively.

Abstract
PURPOSE Differences of sex development (DSD) are congenital conditions that involve variations in individuals' sex chromosomes, genes, external and/or internal genitalia, hormones, and/or secondary sex characteristics. This study sought to elucidate the experiences of adolescents and young adults living with DSD by focusing on their experiences of intimacy and sexual health. METHODS An interpretative phenomenological research design was adopted. Semi-structured qualitative interviews were conducted with 11 Norwegian adolescents and young adults aged 16-26 years who had five different DSD conditions. The interview findings were analysed by means of a reflexive thematic analysis. RESULTS The participants reported feeling different, both in terms of how their body functioned and how their body looked. Lack of knowledge increased this feeling of differentness. Moreover, lack of everyday language with which to talk about intimacy and sexual concerns resulted in the participants feeling stigma. Anticipating stigmatization and lacking everyday language complicated the participants' communication regarding their DSD and sexual health. CONCLUSIONS The sexual experiences of adolescents and young adults with DSD are diverse. Fear of stigmatization and lack of everyday language complicate communication with healthcare professionals and others. Understanding their unique needs is crucial to helping individuals achieve good sexual health.

Abstract
Background Hypospadias is a common genital malformation among boys. Studies indicate that hypospadias is associated with a higher risk of testicular cancer. Other forms of urological cancer may be linked to hypospadias via a mutual aetiology, hormonal dysfunction, or hypospadias complications, but this has not yet been studied. Objective To investigate the association between hypospadias and testicular cancer and the risk of other urological cancers among individuals born with hypospadias. Design setting and participants The study used a population-based male cohort born in Sweden in 1964-2018. Exposure was hypospadias diagnosis in national registers. Outcomes were defined using the Swedish Cancer Register. An extended cohort born from 1940 was used to study cancers among older men. Biological brothers and fathers were linked to investigate familial coaggregation. Outcome measurements and statistical analysis Associations were assessed using Cox proportional-hazards regression analysis, with results presented as hazard ratios. Results and limitations We found that hypospadias was associated with a higher risk of testicular cancer (hazard ratio 2.04, 95% confidence interval 1.42-2.92), especially for proximal hypospadias, but did not observe any clear familial coaggregation of hypospadias and testicular cancer. Hypospadias was associated with Wilms' tumour in childhood. We also found an association between hypospadias and bladder and urethral cancers, but not prostate cancer. The number of cases with hypospadias was small and the results for cancers among older men may be impacted by limitations in register coverage. Conclusions Our study supports the hypothesis of a higher risk of testicular cancer for men with hypospadias, especially with proximal phenotypes. Hypospadias may also be associated with a higher risk of lower urinary tract cancers, although this requires further investigation in older cohorts. Patient summary Boys and men in whom the opening of the urethra is not at the end of the penis (called hypospadias) at birth are at higher risk of developing testicular cancer, although their overall risk is still low. They may also have a higher risk of developing other forms of cancer in the urinary tract.

Abstract
Over the past two decades, China has experienced a significant decline in birth rates, accompanied by a decrease in fertility and changes in major congenital defects. The development of assisted reproductive technology (ART) has brought hope to individuals facing infertility. However, some issues related to reproductive health and congenital defects have arisen. The reasons for the changing profiling of birth defects and the relationship between the decline in fertility and ART need to be further investigated. Lifestyle factors such as nutritional supplementation need to be altered to protect reproductive capacity. Birth defects, such as congenital heart defects and hypospadias, may serve as a signal for understanding the decline in fertility. To improve fertility, the factors contributing to it need to be identified, vital genetic and medical technologies need to be introduced, and environmental interventions, such as nutritional changes, need to be implemented.

Abstract
BACKGROUND Hypospadias affects around 1/200 newborn males. Intrauterine testicular dysfunction may underlie a subset of cases. The long-term endocrine and reproductive outcomes in these men remain largely unknown. METHODS Cross-sectional study in Ghent and Vienna University Hospitals to assess the endocrine and seminal parameters of young adult men (16-21 years) born with non-syndromic hypospadias (NSH) (n = 193) compared to healthy typical males (n = 50). Assessments included physical exam, semen analysis, hormone assays and exome-based gene panel analysis (474 genes). FINDINGS All participants had experienced a spontaneous puberty, in spite of higher LH and INSL3 levels than typical males. Oligo- or azoospermia was observed in 32/172 (18·6%; 99%-CI: 12·2-27·4%) of NSH men; but in 5/16 (31·3%; 99%-CI: 11·1;62·4%) of complex NSH men and in 13/22 (59·1%; 99%-CI: 33·2-80·7%) of those born small for gestational age (SGA). No (likely) pathogenic coding variants were found in the investigated genes. Suboptimal statural growth affected 8/23 (34·8%; 99%-CI: 15·4-61·0%) of men born SGA with NSH. INTERPRETATION Spermatogenesis is significantly compromised in NSH men, especially in those born SGA or those with complex NSH. Long-term andrological follow-up is recommended, including end-pubertal semen analysis. No clear monogenic causes could be demonstrated in our cohort even in proximal or complex NSH. Being born SGA with NSH is frequently associated with poor catch-up growth, requiring growth hormone therapy in some.

Abstract
OBJECTIVES To report the long-term follow-up outcomes of masculinizing surgery in disorders/differences of sex development (DSD), including both physicians' and patients' perspectives on appearance and functional outcome, including sexuality. PATIENTS AND METHODS In total, 1040 adolescents (age ≥16 years) and adults with a DSD took part in this multicentre cross-sectional clinical study in six European countries in 2014/2015. Of those, 150 living in other than the female gender had some kind of masculinizing surgery: hypospadias repair, orchidopexy, breast reduction and/or gonadectomy. The study protocol included medical data collection, an optional genital examination, and patient-reported outcomes including satisfaction with appearance and current sexual functioning. RESULTS Diagnoses included partial and mixed gonadal dysgenesis (45,XO/46,XY; n = 38), Klinefelter syndrome/46,XX males (n = 57), and various 46,XY DSDs (n = 42; e.g. partial androgen insensitivity syndrome, severe hypospadias) and 13 with other diagnoses. Of the participants, 84 underwent hypospadias surgery, 86 orchidopexy, 52 gonadectomy and 32 breast reduction (combinations possible). Physicians evaluated anatomical appearance at genital examination as poor in approximately 11% of patients. After hypospadias surgery, 38% of participants reported that they were (very) dissatisfied with anatomical appearance and 20% with function. The physician and patient evaluations were moderately correlated (r = 0.43). CONCLUSION The majority of participants were neutral to satisfied with the appearance and function in the long-term after masculinizing surgery. Given the initial severe phenotype and a risk of unsatisfactory results after masculinizing surgery in DSD, treatment should be handled by experienced multidisciplinary teams in order to optimize the postoperative results.

Abstract
Congenital malformations often have a genetic background associated with a recurrence risk and may be part of a syndrome. Therefore, for children with a congenital malformation, the parents should be offered genetic counseling, and the child should also be offered the same when they reach adulthood. Hypospadias is a common malformation in boys that arises during genital development in weeks 8 to 16. This results in an underdevelopment of the ventral aspect of the penis with a misplacement of the urethral opening somewhere along the penis, scrotum, or in the perineum and with different degrees of penile curvature. The cause can be monogenic, but generally it is regarded as a complex disorder caused by both genetic and environmental factors. Severe hypospadias and familial cases should be genetically investigated, as for other forms of disorders of sex development, according to current guidelines with sequencing of relevant genes. Hypospadias associated with another independent malformation may be part of a syndrome and should be investigated. Fortunately, boys born with milder hypospadias generally have a good outcome and thus the clinical value of finding a disease-causing mutation appears to be limited especially in light of the present cost of genetic analysis. However, all men born with hypospadias should be advised on the recurrence risk and risk for reduced fertility.

Fertility in men with hypospadias: A nationwide register-based study using dizygotic twinning rates as an indicator of semen quality. Andrology 2021; 9:810-816.

Abstract
BACKGROUND It is not known if impaired fertility in men with hypospadias is caused by decreased semen quality or other factors. Semen quality in men born with hypospadias may be impaired due to effects of androgens or testicular dysgenesis but has been very little studied. OBJECTIVES To study semen quality in men with hypospadias using dizygotic twinning rates as an epidemiological indicator. We further aimed to study men treated for cryptorchidism, given a hypothesized mutual etiology for decreased semen quality. MATERIALS AND METHODS We conducted a population-based study using national Swedish registers. A total of 4,363,165 births between 1964 and 2013 were included. The association between hypospadias and cryptorchidism, and fathering dizygotic multiple births was estimated using logistic regression and presented as odds ratios. The main analyses excluded births conceived using assisted reproductive technology (ART). RESULTS We identified a total of 5317 births with fathers with hypospadias, including 26 dizygotic births conceived unassisted. No significant association was found between hypospadias and dizygotic twinning (OR 1.10, 0.75-1.61). We estimated a significantly increased odds for dizygotic multiple births in men treated for cryptorchidism (OR 1.35, 1.01-1.81) which was decreased after exclusion of ART, but the estimate was not significant (OR 0.75, 0.48-1.18). DISCUSSION Using dizygotic twinning rates as an indicator of semen quality, we did not find any difference between fathers with hypospadias and controls. Due to sample size, we could not analyze phenotypes separately and can therefore not exclude impaired semen quality in severe hypospadias. We could not demonstrate any association between dizygotic twinning and cryptorchidism. Men treated for cryptorchidism were more likely than controls to use ART to conceive. CONCLUSION Men with hypospadias who conceived without ART were not shown to have impaired semen quality using dizygotic twinning as an epidemiological indicator.

Next-generation Sequencing Applied to a Large Cohort of Hypospadiac Patients. Eur Urol 2021; 79:507-515.

Abstract
BACKGROUND Next-generation sequencing (NGS) is generally used for patients with severe disorders of sex development (DSD). However, NGS has not been applied extensively for patients with hypospadias only, and most affected children do not benefit from an etiological diagnosis. OBJECTIVE To evaluate the clinical usefulness of NGS for patients with hypospadias, regardless of severity. DESIGN, SETTING, AND PARTICIPANTS Prospective multicenter research included 293 children with glandular to penoscrotal hypospadias (no undescended testis and no micropenis). After excluding likely pathogenic androgen receptor (AR) variants by Sanger sequencing, an NGS panel tested 336 genes including unexplored candidates in 284 patients. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The rate of pathogenic and likely pathogenic variants was assessed using REVEL, ClinVar, and in-house tools (Captain-ACHAB, MobiCNV, and MobiDetails). RESULTS AND LIMITATIONS Likely pathogenic variants were identified in 16 (5.5%) patients with both Sanger sequencing and NGS taken into account. Some genes were related to DSD (AR, NR5A1, HSD17B3, and MAMLD1), but reverse phenotyping revealed two syndromic disorders with midline defects (MID1) and alteration in the retinoic acid signaling pathway (RARA). Coverage analysis revealed an 18q deletion. Identification of likely pathogenic variants increased with hypospadias severity. Other variants of unknown significance (VUSs) in genes implicated in hypogonadotropic hypogonadism, Noonan syndrome, and genital tubercle development were also identified. Genetic study mainly focused on exonic variants, and most cases remain unexplained. CONCLUSIONS NGS reveals minor forms of DSD, undiagnosed syndromes, or candidate rare variants in new genes, indicating that even patients with mild hypospadias benefit from advanced sequencing techniques. Early molecular diagnosis would help improve follow-up at puberty and medical counseling for initially undiagnosed syndromes. Future studies will improve the diagnosis by investigating the contribution of VUSs. PATIENT SUMMARY Next-generation sequencing enables simultaneous testing of numerous genes and should not be limited to disorders of sex development cases. Even patients with mild hypospadias would benefit from early diagnosis of a genetic defect implicated in sex development or other syndromes.

Abstract
Hypospadias is a common abnormality of the urogenital tract with a wide range of variety in its presentation and severity. The primary aim to correct hypospadias is to restore normal penile function and appearance. Although it can be corrected at any age, early correction between the 6 and 18 months of life is recommended. The functional and cosmetic outcomes have been very-well presented in the literature, although the aspects of sexuality and fertility of hypospadias repair in the long term are vague. In this narrative review, we aimed to gather the data around the sexuality and fertility outcomes of hypospadias repair and acknowledge urologists and parents of boys with hypospadias who will have a correction surgery about future sexual and fertility concerns.
