Hypospadias is one of the most common congenital anomalies that can be treated with surgical reconstruction. The etiology in the majority of cases of hypospadias remains elusive. Androgens are clearly critical for penile development; however, defects in androgen metabolism and/or the androgen receptor explain only a small subset of patients with hypospadias. This paper reviews the present strat...

PURPOSE To review the evolution of the technique of hypospadias repair. METHODS A search of Pubmed, Medline and the Journal of Pediatric Urology was performed, and papers dealing with surgical techniques for hypospadias repair were critally reviewed. Special emphasis was given to papers on the effects in the long term of hypospadias repair on voiding and sexual dysfunction. RESULTS The tech...

Hypospadias is an anomaly of the male urogenital tract which occurs as a result of deficient closure of the urethral groove. Hypospadias is the most commonly seen urogenital anomaly in male neonates, but it is rarely diagnosed during prenatal period. Herein, a severe hypospadias case which was diagnosed by using 2D (two-dimensional) and 3D (three-dimensional) ultrasonography at 28 weeks of preg...

OBJECTIVES To determine the trend of hypospadias incidence in New York State (NYS) by retrospectively evaluating both the incidence and surgical repair rates of hypospadias. Epidemiologic studies in the United States and Europe have suggested an observable trend in the incidence of hypospadias during the past 30 years. A comparison of the results from these studies, however, revealed inconsiste...

The aim was to retrospectively determine the real incidence of congenital penile curvature in various forms of hypospadias, in order to indicate intraoperative assessment and correction of curvature. We analyzed 842 patients with hypospadias who underwent surgery from 2003 to 2010, classified into two groups. First group was intraoperatively checked for curvature as a routine procedure, while a...

BACKGROUND Hypospadias is a common congenital malformation of the male external genitalia. Most cases have an unknown aetiology, which is probably a mix of monogenic and multifactorial forms, implicating both genes and environmental factors. This review summarizes current knowledge about the aetiology of hypospadias. METHODS Pubmed was used to identify studies on hypospadias aetiology publish...

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...
