hypospadias

[hi″po-spa´de-as]

a developmental anomaly in which the urethra opens inferior to its normal position, usually in males with the opening on the underside of the penis or on the perineum. In perineal hypospadias the opening on the perineum is accompanied by severe deformity of the penis and testes so that the individual has male pseudohermaphroditism.

Hypospadias with chordee. From Dorland's, 2000.

female hypospadias a developmental anomaly in the female in which the urethra opens into the vagina.

(hī'pō-spā'dē-ăs), [MIM*146450]

A developmental anomaly characterized by a defect on the ventral surface of the penis so that the urethral meatus is proximal to its normal location; may be associated with chordee; also a similar defect in the female, in which the urethra opens into the vagina. Compare: epispadias.

hypospadias

A congenital abnormality of the penis in which the urine tube (URETHRA) opens on the underside of the organ, either at the neck of the bulb (glans) or further back. The prevalence of the condition has doubled in the last 30 years. Hypospadias causes inconvenience in urination and possible infertility, but surgical correction is possible. Tissue culture can be used to provide sheets of artificially grown natural material to line the extended portion of the urethra.

It is tempting to speculate that epigenetic mechanism(s) could also play an important role in the regulation of primary (sensory/signaling) cilium function and the disruption of such mechanism(s) in the spatiotemporal fashion could affect the development of external male genitalia resulting in diphallia and hypospadias.
