PURPOSE ATF3, an estrogen responsive gene expressed during genital development, could be implicated in the etiology of hypospadias. ATF3 is up-regulated in the foreskin of patients with hypospadias and is implicated in suppression of the cell cycle, which may interfere with urethral cell growth. We sought to investigate the sequence of ATF3 in patients with hypospadias. MATERIAL AND METHODS D...

Concern about apparent increases in the prevalence of hypospadias--a congenital male reproductive-tract abnormality--in the 1960s to 1980s and the possible connection to increasing exposures to endocrine-disrupting chemicals have underlined the importance of effective surveillance of hypospadias prevalence in the population. We report here the prevalence of hypospadias from 1980 to 1999 in 20 r...

BACKGROUND Anogenital distance (AGD) in animals is a sensitive biomarker of fetal endocrine disruption and the associated testicular dysgenesis syndrome (TDS). However, AGD in human infants with cryptorchidism and hypospadias, which are potential manifestations of TDS during childhood, is not clearly described. OBJECTIVE Our aim was to compare AGD in boys with cryptorchidism or hypospadias ag...

BACKGROUND Reports on increasing hypospadias trends are based on birth defect registries, which are prone to inaccuracy. We assessed the prevalence of hypospadias precisely, by prospective examination of all newborns in Rotterdam over a 2-year period. METHODS A total of 7292 consecutive male births were examined for the presence of hypospadias, classified by severity. RESULTS The frequency ...

BACKGROUND The occurrence of inflammatory bowel disease (IBD) and hypospadias has been concurrently increasing, possibly through shared environmental risk factors such as endocrine disrupting compounds. Also, maternal IBD may disturb the normal development of the fetal reproductive tract. However, whether maternal IBD increases the risk of hypospadias in male offspring is unknown. We compared h...

BACKGROUND Cryptorchidism, hypospadias, and testicular germ cell cancer (TGCC) may be symptoms of a testicular dysgenesis syndrome that manifests during fetal life. To address the inheritability of this syndrome, we examined whether family history of cryptorchidism or hypospadias is associated with an increased risk of TGCC. METHODS A total of 2,159,883 men born since 1953, identified through...

OBJECTIVE To review the psychosexual effects on men after hypospadias repair. METHODS We reviewed all English-language publications in the MEDLINE database from the US National Library of Medicine with the search terms 'hypospadias adult', 'psychosexual hypospadias', 'psychosocial hypospadias', and 'social hypospadias'. Each term returned 1036, 35, 19 and 68 results, respectively, which were ...

Hypospadias is the most common anomaly in the male genital tract with an incidence of 0.8-8.2 per 1000 live male births. Routinely, hypospadias cases are repaired after one year of age, and it is recommended that a child with hypospadias not to be circumcised until hypospadias repair is completed. This study was conducted to determine whether or not circumcision prior to hypospadias repair incr...

Hypospadias is a common congenital malformation in boys, characterized by incomplete fusion of the urethral folds, abnormal opening of urethra and different degrees of curvature of the penis. In Sweden, the incidence of hypospadias is 1.14 per 300 male live-births according to the annual Swedish Malformation Registry. Hypospadias is considered to be a complex genetic disorder caused by the inte...

BACKGROUND Hypospadias is a common inborn error of the male urethral development, for which the aetiology is still elusive. Polymorphic variants in genes involved in the masculinisation of male genitalia, such as the androgen receptor, have been associated with some cases of hypospadias. Co-regulators of the androgen receptor start being acknowledged as possible candidates for hormone-resistanc...
