Hemospermia owing to utricular cyst: embryological summary and surgical review.

We report the first case of hemospermia owing to a utricular cyst. The embryologic distinction between utricular cysts, which are of endodermal origin, and müllerian duct cysts, which are of mesodermal origin, is described. The surgical management of utricular and müllerian duct cysts is reviewed, stressing the difficulty and hazards of attempts at complete excision and the efficacy of less heroic surgical procedures.
