Chordee is a condition in which the penis curves downward (that is, in a ventral direction). The curvature is usually most obvious during erection, but resistance to straightening is often apparent in the flaccid state as well. In many cases but not all, chordee is associated with hypospadias. It is usually considered a congenital malformation of unknown cause. Since at an early stage of fetal development the penis is curved downward, it has been proposed that chordee results from an arrest of penile development at that stage.
The curvature of a chordee can involve
1. tethering of the skin with urethra and corpora of normal size;
2. curvature induced by fibrosis and contracture of the fascial tissue (Buck's or dartos) surrounding the urethra;
3. disproportionately large corpora in relation to the urethral length without other demonstrable abnormality of either; or
4. a short, fibrotic urethra that tethers the penis downward (the least common type).
Severe degrees of chordee are usually associated with hypospadias, but mild degrees of curvature may occur in many otherwise normal males. When the curved penis is small and accompanied by hypospadias, deficiency of prenatal androgen effect can be inferred.
The principal treatment of chordee is surgery in infancy, usually by a pediatric urologist. Correction is usually successful.

The chorda tympani are nerves of special sensation given off the facial nerve (VII) inside the skull. They exit via the pterygopalatine fossa rather than the stylomastoid foramen (which is how the facial nerve exits the skull) to supply taste to the anterior two-thirds of the tongue. It also carries parasympathetic secretomotor fibres to the submandibular and sublingual salivary glands, thus allowing secretion of saliva from these glands to occur. Upon leaving the skull, the chorda tympani fuse with the right and left lingual nerves, which are themselves divisions of the mandibular branch of the trigeminal nerve (V).
