Increasing rates of cryptorchidism and hypospadias in human populations may be caused by exogenous environmental agents. We conducted a case-control study of serum levels of p,p'-dichlorodiphenyltrichloroethane (DDT) and its major metabolite, p,p'-dichlorodiphenyldichloroethylene (DDE), and cryptorchidism and hypospadias in the Child Health and Development Study, a longitudinal cohort of pregna...

CONTEXT Hypospadias is a common congenital malformation of the male external genitalia with a multifactorial etiology. Little is known about the genes involved in hypospadias. A few genetic associations have been reported but mainly in studies of small sample size. Most of these associations have not been replicated. OBJECTIVE The aim of this study was to investigate whether previously report...

BACKGROUND/AIM Nowadays surgical intervention is possible in smaller phalluses and younger children with hypospadias disease. Different hormone treatments with different doses, modalities, indications, and treatment times come along with some disputes. The aim of this study is to evaluate the management approaches in hypospadias surgery of surgeons in regards to hormone preparations. MATERIAL...

Hypospadias is the most common penile congenital anomaly [2] and the second most common congenital malformation in males, occurring in approximately one in 125 live male births [3]. Two theories were suggested for development of hypospadias, endodermal theory and ectodermal theory [4]. Types of hypospadias are anterior, middle and posterior with the posterior type account approximately 20% of c...

INTRODUCTION Endocrine disruptors or environmental agents, disrupt the endocrine system, leading to various adverse effects in humans and animals. Although the phenomenon has been noted historically in the cases of diethylstilbestrol (DES) and dichlorodiphenyltrichloroethane (DDT), the term "endocrine disruptor" is relatively new. Endocrine disruptors can have a variety of hormonal activities s...

BACKGROUND The etiology of hypospadias is regarded as a complex disorder with both genetic and environmental contributions. Although alterations in androgen activity have been associated with hypospadias, few associations with estrogen activity have been documented. Here, we assessed genetic polymorphisms in estrogen receptor genes and their association with hypospadias. METHODS Using a case-...

OBJECTIVE The aim was to determine the distribution pattern of hypospadias cases across a well-defined geographic space. MATERIALS AND METHODS The dataset for this study was produced by the Birth Defects Prevention and Surveillance System of the Department of Health of Puerto Rico (BDSS-PR), which linked the information of male newborns of the Puerto Rico Birth Cohort dataset (PRBC; n=92,285)...

OBJECTIVE Mutations in chromosome X open reading frame 6 (CXorf6), a recently described candidate gene involved in the development of male genitalia, have been found in patients with complex 46,XY disorders of sexual development (46,XY DSD) including micropenis, bifid scrotum, and penoscrotal hypospadias. The objective of this work was to identify genomic variants of CXorf6 in patients with iso...

PURPOSE Hypospadias is the most common congenital penile anomaly. Information about current utilization patterns of inpatient hypospadias repair as well as complication rates remain poorly evaluated. MATERIALS AND METHODS The Nationwide Inpatient Sample was used to identify all patients undergoing inpatient hypospadias repair between 1998 and 2010. Patient and hospital characteristics were at...
