BACKGROUND Complex malformations of the female genital tract are often incorrectly identified, treated and reported, probably due to not considering the malformation as a cause of the clinical symptoms and neither the embryological origin of the different elements of the genitourinary tract. METHODS Complex malformations are studied and classified, and new types are presented. The new types o...

congenital malformation (cm) will begin to emerge as one of the major childhood health problems .treatment and rehabilitation of children with congenital malformations are costly and complete recovery is usually impossible. the aim of this study was to determine frequency of cm in yazd central city of the islamic republic of iran to find out if there has been any difference in the rate and type...

The incidence of congenital malformation of the urogenital system is second only to that of the cardiovascular system, yet comparatively little is known about the cellular and molecular mechanisms that regulate urogenital organogenesis. In this chapter, I review recent advances in the developmental biology of the external genitalia, and discuss the implications of this work for our understandin...

background: 49, xxxxy syndrome is a rare sex chromosomal disorder, occurring in 1 per 85,000-100,000 male births. the classical phenotype is ambiguous genitalia, facial dysmorphism, mental retardation and a combination of cardiac, skeletal and other malformations. case: a two month-old boy with intrauterine growth restriction (iugr) and low birth weight, facial dysmorphism, clinodactyly in feet...

A descriptive epidemiological study of simple hypospadias-that is, hypospadias without coexisting malformation outside the genital system-in a birth population of 46,927 singleton males and 1,013 twin males showed that the condition was significantly more common (P < 0.001) in uniovular twin males than in either singleton or binovular twin males. Also the temporal distribution of dates of conce...

BACKGROUND Sex hormones closely regulate development of the male genital organs during fetal life. The hypothesis that xenobiotics may disrupt endogenous hormonal signalling has received considerable scientific attention, but human evidence is scarce. OBJECTIVES We analyse occurrence of hypospadias and cryptorchidism according to maternal and paternal occupational exposure to possible endocri...

Anterior congenital urethrocutaneous fistula is a rare anomaly that may present in an isolated fashion or in association with other anomalies of the genital urinary tract or anorectal malformations. A case of congenital anterior urethrocutaneous fistula nonassociated with other congenital anomalies in a 3-year-old male whose mother has been exposed to Chernobyl's nuclear fallout is described. T...

The following is a report on a congenital vaginal malformation, imperforate vagina, in the common marmoset (Callithrix jacchus). This anomaly was observed for the first time in an adult female in our research colony. There was no uterine and vaginal aplasia or atresia in her grossly normal genital tract. The plasma progesterone concentration suggested that the ovarian cycle had ceased. However,...
