The epithelium of phallic urethra of male (ephur) (TS:20-TS:24) is derived from cloacal endoderm and derived from the urethral plate epithelium (TS:19). Located within the genital tubercle of male. At TS:20, the urethral plate epithelium has not canalised and only the plate is seen. At TS:21, as the plate begins to canalise and form a tube, it is subdivided into the urethral plate epithelium of male (syn: urethral plate), the bilaminar epithelium located distally, and into the phallic urethral tube epithelium (syn: proximal phallic urethral epithelium) which is the part of the urethral epithelium that has septated into a canalised tube proximally, and it is open at the proximal urethral meatus. The proximal urethral meatus closes in males, a process which begins around TS:23 and is not present in males at TS:25. In females, the proximal urethral meatus remains open to TS:27 (closed by TS:28, P8). The epithelium of phallic urethra of male/female becomes the epithelium of penile urethra/clitoral urethra at TS:25.
