There are numerous things that can cause blockage of sperm or blockage of the reproductive track. You can be born with a blockage, a condition called congenital absence of the vas deferens, meaning being born without the spermduct or tube called a “vas,” that a doctor cuts when he performs a vasectomy. The testicles make sperm as normal but the sperm can't be released because there is no tube or no "plumbing" so to speak. Another issue that can cause blockage of the sperm tube is a vasectomy; which is designed to cause a blockage so that a man can't impregnate a woman. He might later change his mind and decide he wants to conceive again. There are issues such as infection, chlamydia and gonorrhea for example, that can cause blockages to the reproductive tract. There can be cysts or disorders of the prostate that also can cause blockages for sperm, so there are numerous things that may cause an obstruction.
