Chordee

HP:0000041

What it means

A congenital anomaly of the penis characterized by ventral (i.e., downward), lateral, or ventrolateral curvature of the shaft and glans penis of more than 30 degrees.

The degree of variation of penis curvature is a continuum, but traditionally 30 degrees is considered the threshold for surgical intervention on chordee. Bowing usually becomes more obvious in an erect penis, but is frequently also palpable when stretching a flaccid penis. Chordee can be congenital or acquired; if the former, it can be associated with Webbed Penis or Hypospadias, which should be coded separately.
