Azoospermia, defined as complete absence of sperm from the ejaculate, is present in less than 1% of all men and in 10-15% of infertile men. There are many causes of azoospermia
Failure of hormones to adequately stimulate the testicles to produce sperm (also known as Pre-testicular)
Primary testicular failure in which the sperm producing cells in the testicles are either missing or damaged
Obstruction of the sperm delivery system (also known as Post-testicular)
This article will focus on obstructions in the sperm delivery system.
Obstruction is responsible for approximately 40% of cases of azoospermia. Obstructive azoospermia may result from blockage in any of the tubes leading from the testicle to the opening in the tip of the penis. These tubes are
Epididymis
Vas Deferens
Ejaculatory duct
Vasectomy is the most common cause of obstruction in the vas deferens. Severe genital or urinary infections, injury during scrotal or inguinal surgery and birth defects are other common causes of obstructive azoospermia.
