Abstract:
Ejaculatory duct obstruction is an infrequent cause of obstructive azoospermia, occurring in up to 5 % of such patients. However, it is potentially correctable and warrants consideration in the differential diagnosis of the patient presenting for infertility evaluation. This review provides an overview of ejaculatory duct obstruction: its various etiologies, presentation, and associated clinical assessment. It includes a description of diagnostic imaging and interventional studies available to the practicing urologist and concludes with a discussion of current endoscopic management.
