This is a cause which occurs when the sperm are blocked from exiting the testicles in a variety of spots. This condition of Azoospermia can be treated and reversed with microsurgery. According to study, the blockage can be found in men’s epididymis which is 65% of the time, 30% in the vas deferens and 5% of the time in the ejaculatory duct. The microsurgery will be performed to know the actual location of the blockage which will be removed so that the sperm will start moving in the ejaculate and the result is the successful pregnancy.
This is a cause which occurs when the sperm isn’t being produced, or in some cases, it may be produced but at very low levels into a man’s ejaculate. This condition is called as severe oligospermia, and while it is serious, the sperm retrieval and assisted reproductive methods can make the pregnancy possible.
