Success rate of vas deferens blockage surgery

In modern society, many men are diagnosed with infertility during examinations. The main cause of male infertility is vas deferens blockage. After being diagnosed with vas deferens blockage, you should go to the hospital in time to take appropriate treatment methods to ensure the patency of the vas deferens and the normal reproductive function of a man. So what is the success rate of vas deferens blockage surgery?

Vas deferens obstruction is the most common cause of male obstructive azoospermia, mainly due to acquired factors, such as inflammation of the epididymis, vasectomy, or blockage caused by cysts and stones in the ejaculatory duct. Different surgical methods are used in different parts, and the success rate is also different. If it is the blockage of the epididymis, then after we anastomose the vas deferens and the epididymis to reopen it, the success rate can reach more than 70%.

Some people have sperm in their semen after the vas deferens and epididymis are unblocked, which can make their wives pregnant naturally. The success rate of natural pregnancy is about 30% to 40%. If there is still no sperm in the semen after recanalization, or the amount of sperm is very small, you may still need to use IVF to get pregnant. There is another situation. If the blockage of the vas deferens is in the ejaculatory duct, such as ejaculatory duct cyst, then the success rate of surgery should be more than 90%.

The success rate of surgical unblocking of vas deferens obstruction is related to the severity of the obstruction and the location of the obstruction. The success rate of traditional surgical unblocking of vas deferens is not high. With the development of technology, the success rate of vas deferens unblocking is greatly improved by using minimally invasive surgery under a microscope. However, it is mainly divided into unblocking surgery of vas deferens segment obstruction and unblocking of vas deferens and epididymis segment obstruction. Among them, the success rate of unblocking of vas deferens and epididymis segment obstruction is higher, with a success rate of more than 70% for microscopic surgery, and the success rate of unblocking of vas deferens and vas deferens obstruction is lower, at about 60%.

You have to look at the degree of blockage of the vas deferens and the location of the blockage. The more common is blockage in two locations, generally there is a blockage section between the vas deferens, and there is another possibility that there is a blockage section at the connection between the vas deferens and the epididymis. The probability of successful surgery is lower for the blocked section between the vas deferens. The success rate is higher for the blocked section between the vas deferens and the epididymis. And it is also related to different surgical methods. There are mainly two surgical methods now. One is the traditional anastomosis under the naked eye, and the blocked area is unblocked. The other is to perform surgery under a microscope, which is a microsurgical technique for unblocking. If the blockage is between the vas deferens, the probability of unblocking should be more than 50% if the surgery is performed under a microscope. If the blockage is between the vas deferens and the epididymis, the chance of unblocking it with microsurgery should be over 70%.
