A qualitative content analysis of the experience of living with hypospadias: varying impact on identity and interpersonal relationships. Front Pediatr 2024; 12:1459561. [PMID: 39268362 PMCID: PMC11390511 DOI: 10.3389/fped.2024.1459561] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2024] [Accepted: 08/19/2024] [Indexed: 09/15/2024] Open
Abstract
Objectives There is a lack of in-depth studies on men's personal experiences of having hypospadias across different aspects of their lives. We therefore aimed to explore the experience of having hypospadias in relation to identity and interpersonal relationships. Subjects and methods Using purposive sampling, we included 17 adult men aged 20-49 with variation in hypospadias phenotype. The informants further represented variation in sexuality, relationship status, parental status, and familial cultural context. In-depth interviews were conducted with each informant and the data was analysed using qualitative content analysis. Results We identified four categories. Firstly, The internal experience of hypospadias in relation to being different, being impacted, and being masculine. The remaining three categories related to interpersonal spaces: Intimate spaces, comprising personal relationship with sex, having sex, and being in a relationship; Familial spaces, comprising being a son, and becoming a father; and Public spaces, comprising being hidden, being naked, and peeing. We identified the latent theme varying impact and coping, highlighting differences in experiences relating to both the internal and interpersonal. Discussion Issues related to hypospadias included struggles with identity and confidence, as well as recurring patterns of social and sexual avoidance. While informants generally related to certain shared experiences, there is large variation in how much hypospadias impacts life, ranging from hardly at all to extensively. This could also fluctuate over time, with puberty and adolescence being an especially sensitive period. Functional and aesthetic outcomes are potentially important for well-being, especially in the case of more severe complications, while personal and interpersonal circumstances play a role in coping and the overall experience of the individual. Conclusion Healthcare, research, and other channels such as patient groups may be able to offer support to those who need it to help more boys and men with hypospadias live unhindered lives.

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.

Abstract
Anti-Müllerian hormone (AMH) is secreted by Sertoli cells and is responsible for the regression of Müllerian ducts in the male fetus as part of the sexual differentiation process. Serum AMH concentrations are at their lowest levels in the first days after birth but increase after the first week, likely reflecting active Sertoli cell proliferation. AMH rises rapidly in concentration in boys during the first month, reaching a peak level at ∼6 months of age, and it remains high during childhood, then they will slowly decline during puberty, falling to low levels in adulthood. Serum AMH measurement is used by pediatric endocrinologist as a specific marker of immature Sertoli cell number and function during childhood. After puberty, AMH is released especially by the apical pole of the Sertoli cells toward the lumen of the seminiferous tubules, resulting in higher levels in the seminal plasma than in the serum. Recently, AMH has received increasing attention in research on male fertility-related disorders. This article reviews and summarizes the potential contribution of serum AMH measurement in different male fertility-related disorders.

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
Background Hypospadias is a common congenital malformation often related to the effect of androgens in utero. While hypogonadism is associated with many potential health risks including metabolic and cardiovascular disease, the risk of clinical hypogonadism and comorbidities in men with hypospadias later in life has not been studied. Objectives Investigate the risk of hypogonadism and somatic comorbidities in adolescents and men born with hypospadias. Materials and methods We conducted a population‐based cohort study using Swedish registers. Associations between hypospadias and hypogonadism, delayed puberty, metabolic, and cardiovascular disease respectively were estimated using Cox proportional hazards regression. Body measurements from military conscription were analysed in a subpopulation as indicators of growth and cardiometabolic risk. We used sibling comparison analyses to control for familial confounding. Results Using register data, a total of 2,165,255 men including 9,714 men born with hypospadias were followed from the age of 10 to a maximum of 60 years. We found an association between hypospadias and hypogonadism (Hazard ratio (HR) 3.27, 95% confidence interval (CI) 2.33–4.59) which was more pronounced in proximal hypospadias. Men with hypospadias had shorter average height than their brothers and the general population. We further found an increased risk of delayed puberty (HR 1.49, 95% CI 1.08–2.07), diabetes mellitus type 2 (HR 1.57, 95% CI 1.18–2.09) and cardiovascular disease (HR 1.47, 95% CI 1.27–1.71). Discussion We found an increased risk of hypogonadism, metabolic and cardiovascular disease in men born with hypospadias, increasing with severity of phenotype, as well as impacted growth. These results indicate discruptions in androgen function past childhood, although some of the associations may be due to other underlying aetiologies. Conclusion Hypospadias is associated with an increased risk of androgen‐related comorbidity in adolescence and adulthood. We suggest that this can be considered clinically, while further research is needed, especially in older populations.

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
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.

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.

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.

Abstract
BACKGROUND Hypospadias is one of the most common congenital disorders of the urogenital system that is repaired by surgical method. Literature review shows that silicone gel is effective in preventing and improving hypertrophic scars after surgery. Thus, we conducted this study to evaluate the effect of silicone gel on scar reduction after surgical repair of hypospadias. MATERIALS AND METHODS In this randomized double-blind clinical trial, 64 patients who had undergone surgical repair of hypospadias were divided into two groups: 32 patients in the intervention group (silicone gel) and 32 in the control group (placebo). Then, the patients in the silicone gel treatment group were treated twice per day for two months on the site of surgical wound, and the patients in the control group were treated with Vaseline twice per day for two months on the site of surgical wound, too. Scar characteristics (pigmentation, vascularity, pliability, and height) were recorded based on Vancouver's scars scale. Finally, the results of the two treatments on reduction of scars after surgical repair were compared between the two groups. Data were analyzed using SPSS-24. RESULTS There were significant differences between the two groups in scar characteristics after surgical repair of hypospadias, such as vascularity, pliability, and height (P˂0.05); however, there was no significant difference in pigmentation (P>0.05). CONCLUSION The results of this study showed that silicone gel had considerable effects on reduction of scars after surgical repair of hypospadias. However, further studies with larger sample size are recommended to confirm our conclusion.

Analysis of the association between paternity and reoperation for urethral obstruction in adult hypospadias patients who underwent two-stage repair in childhood. BMC Urol 2019; 19:88.

Abstract
Background The association between surgical outcome of hypospadias repair and long-term male reproductive function has not been documented. The purpose of this study was to clarify association between paternity in adult hypospadias patients and reoperation for urethral obstruction after two-stage repair during childhood. Methods Ninety hypospadias patients who underwent the same kind of two-stage repair in our institute by a single surgeon, were initially treated at < 18 years old, and who were ≥ 18 years old during the survey were included in the study. Present physical, social, and life status were evaluated by a mailed self-entry questionnaire, and clinical background and surgical outcome data were evaluated by medical records. National survey data of the general population were used as external control. The paternity rate of the patient groups was evaluated by Kaplan-Meier curve analysis and log-rank tests. Results Twenty-six patients (28.9%) underwent 43 reoperations after completion of the initial repair. Twelve patients were reoperated for obstructive complication (Study group) and were compared with 14 patients who were reoperated only for non-obstructive causes and 64 patients who were not reoperated as Study control group (N = 78). The Study group patients showed sexual intercourse rate and marriage rate not statistically different in comparison with the Study control, although marriage rate at 32.5 years old were lower than the general population (p = 0.048, z-test). None of the Study group achieved paternity, which showed a significant difference to the Study control (p = 0.032, log-rank test). The difference was also statistically significant in the analysis among the 31 married patients (p = 0.012, log-rank test). Patients reoperated for obstructive complication documented worsened Quality of Life score in the International Prostate Symptom Score (2.3 ± 2.0 vs. 1.4 ± 1.2, p = 0.031, t-test) and ejaculation problems (66.7% vs. 17.4%, p = 0.003, chi-square test). Conclusions History of reoperation for obstructive complication was associated with lower paternity rate in patients with hypospadias, presumably for multifactorial causes associated with marriage age and ejaculation problems. The present results may implicate importance of uncomplicated urethroplasty during childhood for achieving paternity, although it should be further tested in the future for larger groups of hypospadias patients.

Abstract
Purpose The factors affecting spermatogenesis in adulthood in patients with hypospadias (HS) are not clearly understood. In the present study, risk factors affecting post-pubertal high serum follicle-stimulating hormone (FSH) were evaluated in patients with HS. Materials and methods Among those with a history of HS surgery, patients in whom endocrinological evaluation regarding pituitary–gonadal axis was performed at 15 years of age or older between March 2004 and April 2018 were enrolled in the present study. High serum FSH was defined as greater than 10 mIU/ml. The severity of HS was divided into mild and severe. Factors affecting the post-pubertal high serum FSH were estimated. Results Seventy-nine patients were included in the present study. The severity of HS was mild in 35 and severe in 44. History of undescended testis (UDT) was confirmed in 12. High serum FSH was detected in nine. On logistic regression model analysis, a history of UDT was the only significant factor for high serum FSH. The incidence of high serum FSH in patients with UDT was significantly higher than that in those without UDT (58.3% vs 7.5%, p < 0.01). When stratified by severity of HS and the presence of UDT, high serum FSH was detected in 70% in patients with severe HS and UDT, whereas less than 10% in other groups. Conclusions A history of UDT was a significant factor for post-pubertal high serum FSH in patients with HS. Accordingly, the presence of UDT may be a marker for impaired spermatogenesis in patients with HS, especially in severe cases.

Prevalence and risk factors of testicular microlithiasis in patients with hypospadias: a retrospective study. BMC Pediatr 2018; 18:179. [PMID: 29843681 PMCID: PMC5975416 DOI: 10.1186/s12887-018-1151-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2017] [Accepted: 05/18/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND It has been described that the incidence of testicular microlithiasis is high in several congenital disorders which may be associated with testicular impairment and infertility. Several reports have shown that a prepubertal or pubertal hormonal abnormality in the pituitary-gonadal axis was identified in some patients with hypospadias that is one of the most common disorders of sex development. However, exact prevalence or risk factors of testicular microlithiasis in patients with hypospadias have not reported so far. In the present study, to clarify the prevalence and risk factors of testicular microlithiasis in patients with hypospadias, a retrospective chart review was performed. METHODS Children with hypospadias who underwent testicular ultrasonography between January 2010 and April 2016 were enrolled in the present study. Severity of hypospadias was divided into mild and severe. The prevalence and risk factors of testicular microlithiasis or classic testicular microlithiasis were examined. RESULTS Of 121 children, mild and severe hypospadias were identified in 66 and 55, respectively. Sixteen children had undescended testis. Median age at ultrasonography evaluation was 1.7 years old. Testicular microlithiasis and classic testicular microlithiasis were documented in 17 children (14.0%) and 8 (6.6%), respectively. Logistic regression analysis revealed that presence of undescended testis was only a significant factor for testicular microlithiasis and classic testicular microlithiasis. The prevalence of testicular microlithiasis or classic testicular microlithiasis was significantly higher in children with undescended testis compared to those without undescended testis (testicular microlithiasis; 43.8% versus 9.5% (p = 0.002), classic testicular microlithiasis; 37.5% versus 1.9% (p < 0.001). CONCLUSIONS The current study demonstrated that the presence of undescended testis was only a significant risk factor for testicular microlithiasis or classic testicular microlithiasis in patients with hypospadias. As co-existing undescended testis has been reported as a risk factor for testicular dysfunction among patients with hypospadias, the current findings suggest that testicular microlithiasis in children with hypospadias may be associated with impaired testicular function. Conversely, patients with isolated HS seem to have lower risks for testicular impairment. Further investigation with longer follow-up will be needed to clarify these findings.

Abstract
Paediatric urological surgery is often required for managing congenital and acquired disorders of the genitourinary system. In this Series paper, we highlight advances in the surgical management of six paediatric urological disorders. The management of vesicoureteral reflux is evolving, with advocacy ranging from a less interventional assessment and antimicrobial prophylaxis to surgery including endoscopic injection of a bulking agent and minimally invasive ureteric reimplantation. Evidence supports early orchidopexy to improve fertility and reduce malignancy in boys with undescended testes. A variety of surgical techniques have been developed for hypospadias, with excellent outcomes for distal but not proximal hypospadias. Pelvi-ureteric junction obstruction is mostly detected prenatally; indications for surgery have been refined with evidence, and minimally invasive pyeloplasty is now standard. The outlook for patients with neurogenic bladder has been transformed by a combination of clean intermittent catheterisation, algorithms of diagnostic investigations, and innovative medical and surgical therapies. Posterior urethral valves are associated with considerable mortality; fetal diagnosis allows stratification of candidates for intervention, but ongoing bladder dysfunction in patients after valve ablation remains a cause of long-term morbidity.

Abstract
INTRODUCTION Hypospadias is a congenital anomaly of the urogenital tract characterized by abnormal location of the external urethral meatus over ventral aspect of penis. The ideal time to correct primary hypospadias is when aged 6-12 months. However, in some developing countries, such as ours, this anomaly may be left untreated until adulthood. There are multiple risk factors responsible for development of this anomaly, out of which paternal sub fertility is one of them. As the child grows into adulthood, fertility status becomes an important issue, frequently raised by patients. AIM To evaluate the fertility potential of adult hypospadiac patients and to rule out the effect of age of surgical correction over fertility potential. MATERIALS AND METHODS Seventy three adult patients of hypospadias were prospectively evaluated, out of which 43 were operated during adulthood. All patients underwent measurement of penile length and circumference in both flaccid and erect positions along with testicular volume, serum LH, FSH and testosterone and semen analysis. A set of questionnaire was given to all the patients which included assessment of erectile function (IIEF-5), ejaculatory function, strength of libido and level of satisfaction after sexual intercourse. Results were compared with an age matched control group of 70 healthy person. RESULTS Out of 73 patients with a mean age of 23.73 years, 14(19.17%) had proximal and rest 59(80.82%) had distal type of hypospadias. Mean penile length in both type of hypospadiac patients under both flaccid and erect conditions (7.92±1.33 and 9.62±1.31cm) were significantly shorter than those of control (10.78±0.94 and 13.15±1.15 cm) (p<0.001). In spite of short penile length, the level of satisfaction of all patients and their partner after penetrating intercourse were comparable to control (p>0.05). The strength of libido (p>0.05) was comparable with control in both type of hypospadiac patients; however IIEF-5 scores was poor in the proximal type of hypospadias. Semen volume (ml), sperm concentration (mill/ml), active sperm motility (%), and normal sperm morphology were comparable between distal hypospadiac group and control (p>0.05), however these parameters were poor in proximal type. The serum FSH and LH levels were significantly higher and serum testosterone level was significantly lower in hypospadiac patients than control (p <0.001). However, no difference in testicular size was found. The patients who were operated during childhood had shorter penile length compared to patients operated during adulthood. CONCLUSION Fertility potential parameters in distal type of hypospadias were comparable with control. However the proximal type had poor erectile function and semen quality. Patients operated in either childhood or in adulthood, there was no significant difference in fertility potential.

Abstract
We investigated the frequency of copy number variations (CNVs) in the Y chromosome of Japanese children with hypospadias. We analyzed the copy number of the azoospermia factor (AZF) region and SRY, using multiplex ligation-dependent probe amplification. Four AZF-linked CNVs, including one novel simple duplication, were identified in 39 of 89 patients, at a frequency comparable to that of those in unaffected individuals. SRY-linked CNVs were absent in our patients. The results imply that CNVs in the AZF region and SRY are not associated with the risk of hypospadias in the Japanese population, although the pathogenicity of the AZF-linked simple duplication remains to be elucidated.

Abstract
Although common reproductive problems, such as male infertility and testicular cancer, present in adult life, strong evidence exists that these reproductive disorders might have a fetal origin. The evidence is derived not only from large epidemiological studies that show birth-cohort effects with regard to testicular cancer, levels of testosterone and semen quality, but also from histopathological observations. Many infertile men have histological signs of testicular dysgenesis, including Sertoli-cell-only tubules, immature undifferentiated Sertoli cells, microliths and Leydig cell nodules. The most severe gonadal symptoms occur in patients with disorders of sexual development (DSDs) who have genetic mutations, in whom even sex reversal of individuals with a 46,XY DSD can occur. However, patients with severe DSDs might represent only a small proportion of DSD cases, with milder forms of testicular dysgenesis potentially induced by exposure to environmental and lifestyle factors. Interestingly, maternal smoking during pregnancy has a stronger effect on spermatogenesis than a man's own smoking. Other lifestyle factors such as alcohol consumption and obesity might also have a role. However, increasing indirect evidence exists that exposure to ubiquitous endocrine disrupting chemicals, present at measurable concentrations in individuals, might affect development of human fetal testis. If confirmed, health policies to prevent male reproductive problems should not only target adult men, but also pregnant women and their children.

Minor hypospadias: the "tip of the iceberg" of the partial androgen insensitivity syndrome. PLoS One 2013; 8:e61824.

Abstract
BACKGROUND Androgens are critical in male external genital development. Alterations in the androgen sensitivity pathway have been identified in severely undermasculinized boys, and mutations of the androgen receptor gene (AR) are usually found in partial or complete androgen insensitivity syndrome (AIS). OBJECTIVE The aim of this study was to determine whether even the most minor forms of isolated hypospadias are associated with AR mutations and thus whether all types of hypospadias warrant molecular analysis of the AR. MATERIALS AND METHODS Two hundred and ninety-two Caucasian children presenting with isolated hypospadias without micropenis or cryptorchidism and 345 controls were included prospectively. Mutational analysis of the AR through direct sequencing (exons 1-8) was performed. In silico and luciferase functional assays were performed for unreported variants. RESULTS Five missense mutations of the AR were identified in 9 patients with glandular or penile anterior (n = 5), penile midshaft (n = 2) and penile posterior (n = 2) hypospadias, i.e., 3%: p.Q58L (c.173A>T), 4 cases of p.P392S (c.1174C>T), 2 cases of p.A475V (c.1424C>T), p.D551H (c.1651G>C) and p.Q799E (c.2395C>G). None of these mutations was present in the control group. One mutation has never been reported to date (p.D551H). It was predicted to be damaging based on 6 in silico models, and in vitro functional studies confirmed the lowered transactivation function of the mutated protein. Three mutations have never been reported in patients with genital malformation but only in isolated infertility: p.Q58L, p.P392S, and p.A475V. It is notable that micropenis, a cardinal sign of AIS, was not present in any patient. CONCLUSION AR mutations may play a role in the cause of isolated hypospadias, even in the most minor forms. Identification of this underlying genetic alteration may be important for proper diagnosis and longer follow-up is necessary to find out if the mutations cause differences in sexual function and fertility later in life.

Abstract
OBJECTIVES Considerable interest and controversy over a possible decline in semen quality during the 20th century raised concern that semen quality could have reached a critically low level where it might affect human reproduction. The authors therefore initiated a study to assess reproductive health in men from the general population and to monitor changes in semen quality over time. DESIGN Cross-sectional study of men from the general Danish population. Inclusion criteria were place of residence in the Copenhagen area, and both the man and his mother being born and raised in Denmark. Men with severe or chronic diseases were not included. SETTING Danish one-centre study. PARTICIPANTS 4867 men, median age 19 years, included from 1996 to 2010. OUTCOME MEASURES Semen volume, sperm concentration, total sperm count, sperm motility and sperm morphology. RESULTS Only 23% of participants had optimal sperm concentration and sperm morphology. Comparing with historic data of men attending a Copenhagen infertility clinic in the 1940s and men who recently became fathers, these two groups had significantly better semen quality than our study group from the general population. Over the 15 years, median sperm concentration increased from 43 to 48 million/ml (p=0.02) and total sperm count from 132 to 151 million (p=0.001). The median percentage of motile spermatozoa and abnormal spermatozoa were 68% and 93%, and did not change during the study period. CONCLUSIONS This large prospective study of semen quality among young men of the general population showed an increasing trend in sperm concentration and total sperm count. However, only one in four men had optimal semen quality. In addition, one in four will most likely face a prolonged waiting time to pregnancy if they in the future want to father a child and another 15% are at risk of the need of fertility treatment. Thus, reduced semen quality seems so frequent that it may impair the fertility rates and further increase the demand for assisted reproduction.

Abstract
Background Testicular dysgenesis syndrome (TDS) is a common disease that links testicular germ cell cancer, cryptorchidism and some cases of hypospadias and male infertility with impaired development of the testis. The incidence of these disorders has increased over the last few decades, and testicular cancer now affects 1% of the Danish and Norwegian male population. Methods To identify genetic variants that span the four TDS phenotypes, the authors performed a genome-wide association study (GWAS) using Affymetrix Human SNP Array 6.0 to screen 488 patients with symptoms of TDS and 439 selected controls with excellent reproductive health. Furthermore, they developed a novel integrative method that combines GWAS data with other TDS-relevant data types and identified additional TDS markers. The most significant findings were replicated in an independent cohort of 671 Nordic men. Results Markers located in the region of TGFBR3 and BMP7 showed association with all TDS phenotypes in both the discovery and replication cohorts. An immunohistochemistry investigation confirmed the presence of transforming growth factor β receptor type III (TGFBR3) in peritubular and Leydig cells, in both fetal and adult testis. Single-nucleotide polymorphisms in the KITLG gene showed significant associations, but only with testicular cancer. Conclusions The association of single-nucleotide polymorphisms in the TGFBR3 and BMP7 genes, which belong to the transforming growth factor β signalling pathway, suggests a role for this pathway in the pathogenesis of TDS. Integrating data from multiple layers can highlight findings in GWAS that are biologically relevant despite having border significance at currently accepted statistical levels.

Abstract
OBJECTIVE There are few studies of outcome in male patients with undefined 46 XY disorder of sex development (DSD). We aimed to assess testicular function and clinical characteristics after puberty in men with idiopathic 46 XY DSD. Design We conducted a University Hospital-based observational follow-up study. METHODS Nineteen patients with severe hypospadias associated with other signs of defective virilization, such as microphallus, cryptorchidism, and/or bifid scrotum, who were initially managed during childhood between 1988 and 1994, were evaluated at a median age of 17.6 (16.3; 17.8) years. Outcome measures included clinical findings and serum testosterone, FSH, LH, and inhibin B concentrations. RESULTS Testicular function was normal in only five (26%) patients. Impaired testicular function was observed in 14 (74%) patients and was partial (n=6; 32%) or total (n=8; 42%), requiring testosterone treatment for the initial (n=2) or secondary (n=6) induction of puberty. Undescended testis (unilateral n=3, bilateral n=2) was found and surgically managed only in the 14 patients with testicular impairment. Testosterone treatment in early childhood greatly increased penis length in all patients, but persistent microphallus following surgical treatment was observed at the end of puberty in most patients, with no difference between patients with and without testicular dysfunction (penis length of 68 (60; 75) vs 65 (60; 65) mm; P=0.42). Half the patients presented an adult height more than 5 cm below their target height. CONCLUSION Men diagnosed with idiopathic 46 XY DSD during childhood are at high risk of testicular insufficiency and persistent micropenis, and this should be taken into account during the follow-up.

Abstract
OBJECTIVE Increasing use of infertility treatment and a decline in demographic fertility in some countries have raised concern whether human fecundity is declining or has declined over time. A dramatic decline in semen quality over the past half-century has been proposed and widely discussed, but none of the existing studies provide data good enough for coming to any firm conclusion. RESULTS Results from 19 articles published during the last 5 years on semen quality and fecundity, covering data from the Nordic countries since the year 2000, do not indicate an ongoing decline in fertility. CONCLUSION We will probably never know, whether semen quality and fecundity has declined over time, but we may be able to monitor biological fecundity and semen quality over time from now on. There are both research initiatives and interest from official channels that could provide more funding for infertility research.

Abstract
It has been hypothesized that poor semen quality, testis cancer, undescended testis, and hypospadias are symptoms of one underlying entity--the testicular dysgenesis syndrome--leading to increasing male fertility impairment. Though testicular cancer has increased in many Western countries during the past 40 years, hypospadias rates have not changed with certainty over the same period. Also, recent studies demonstrate that sperm output may have declined in certain areas of Europe but is probably not declining across the globe as indicated by American studies. However, at the same time, there is increasing recognition of male infertility related to obesity and smoking. There is no certain evidence that the rates of undescended testes have been increasing with time during the last 50 years. In more than 95% of the cases, hypospadias is not associated with cryptorchidism, suggesting major differences in pathogenesis. Placental abnormality may occasionally cause both cryptorchidism and hypospadias, as it is also the case in many other congenital malformations. The findings of early orchidopexy lowering the risk of both infertility and testicular cancer suggest that the abnormal location exposes the cryptorchid testis to infertility and malignant transformation, rather than there being a primary abnormality. Statistically, 5% of testicular cancers only are caused by cryptorchidism. These data point to the complexity of pathogenic and epidemiologic features of each component and the difficulties in ascribing them to a single unifying process, such as testicular dysgenesis syndrome, particularly when so little is known of the actual mechanisms of disease.
