Ejaculatory Duct Obstruction. The tubes that sperm travel along are delicate and can be blocked by injury, infection, cancer or surgery.If a sperm was the size of a man, it would have to travel along more than 12 miles of pipes before it left the man’s body. That’s a lot of pipes, so perhaps it’s no surprise that sometimes they get a blockage. Jan 18, 2017 · Blockages in the different ducts that carry the sperm from the testes to the urethra can cause problems for sperm transportation. The three main categories of problems arising in sperm transportation can be classified under the categories of congenital disorders, acquired disorders and functional obstruction.4.2/5(5).
Blockage of Ejaculatory Duct. The function of the epididymi is to carry the sperms from the testes (where sperms are produced) to the vas deferens to ejaculate. However, when there is a blockage in the ejaculatory duct or epididymis, the sperm will not be ejaculated, though they are produced in the testes. An obstruction of the ejaculatory duct can be congenital or acquired, and it involves the obstruction of either one or both of the ejaculatory ducts. This prevents semen, or most of the semen, from being ejaculated. The resulting low semen volume and low to no sperm count make this a .
A blockage or obstruction can develop in one or both of the ejaculatory ducts, preventing sperm from getting into the ejaculate. Sometimes the ducts are blocked from birth (i.e., congenital) and in other cases they are acquired. Dr. Turek has described several types of EDO. Particularly in cases of secondary subfertility following a prostatic infection the ejaculatory duct will be blocked proximal to these openings. A resectoscope with a 24f loop is used. The lesion is localized by TRUS (Figure 11A) while the resectoscope is in place.
