Are there different types of azoospermia?
Yes. There are two different types of azoospermia. Obstructive azoospermia is the complete lack of sperm in the ejaculate due to a blockage in the male reproductive tract or the absence of the part of the reproductive tract that carries sperm from the testicle to outside the body. A blockage, or obstruction, may have been present at birth or may have occurred as a result of an infection or severe trauma to the testicles or the tubules surrounding the testicles that transport the sperm out of the body. Men with obstructive azoospermia almost always have some sperm in their testicles, but these sperm are not found in the semen because of the blockage or absence of part of the reproductive tract.
