The mesonephric ducts terminate in the urogenital sinus on either side of the sinus tubercle at 49 days. At the rostral end of the sinus tubercle, the urogenital sinus is referred to as the vesicourethral canal, and the bladder and the whole of the female urethra arises from it. The portion of the urogenital sinus caudal to the sinus tubercle continues to be referred to as the urogenital sinus and is subdivided into pelvic and phallic portions.
