[Prostatic utricle, a rare but potentially curable cause of male sterility].

This case report describes a patient presenting a cyst of the prostatic utricule that was detected during assessment for sterility and removed surgically. A review of the pertinent literature is proposed. Azoospermia or severe oligospermia associated with a low ejaculation volume are the main manifestations. Transrectal ultrasonography is the diagnostic examination of choice. In most cases incision of the mouth of the utricule promptly abolishes sterility and enables fertilization.
