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-...

Reports suggesting an increasing incidence of male genitourinary anomalies such as hypospadias, possibly related to environmental factors such as environmental estrogen-like compounds, have recently received considerable publicity. These reports are based on birth defects registry data, and there may be variation in the completeness of the registries used. We analyzed temporal trends in the pre...

Hypospadias is one of the most common congenital anomalies. Increased exposure to environmental factors (endocrine-disrupting chemicals and smoking) or maternal endogenous estrogen may cause hypospadias because male sexual differentiation is dependent on normal androgen homeostasis. Moreover, interactions between genetic factors and cigarette smoking and other chemicals have been suggested. It ...

BACKGROUND Hypertensive disorders occur in an estimated 5-10% of pregnancies, but few studies have examined birth defects in relation to high blood pressure and antihypertensive medication use. The objective of this study was to investigate the relationship between high blood pressure, antihypertensive medication use, and severe hypospadias. METHODS We used data from the National Birth Defect...
