title: A rare case of obstructive azoospermia due to compression of the seminal vesicle and ejaculatory duct by a large lower ureteric stone.
abstract: Male infertility due to obstructive azoospermia is a well-known entity. It is characterised by obstruction to the outflow of sperms either in the epididymis, vas, seminal vesicles or the ejaculatory ducts. We describe a rare case of obstructive azoospermia due to compression of the ejaculatory duct and seminal vesicle by a large lower ureteric stone in a 30-year-old man who had infertility for the past ten years. The patient's azoospermia resolved after removal of the stone.
