Urogenital folds

Encyclopedia : U : UR : URO : Urogenital folds

The urogenital folds are an embryological structure which give rise to a portion of the external genitalia. In the female, the urogenital folds become the labia minora while in the male they form the urethra and a portion of the shaft of the penis, not including the glans.

In the male, failure of the urogenital folds to fuse during development leads to a condition known as hypospadias.
