Patient's question:
Got a vas deferens blockage, my girlfriend doesn't know, but she recently got pregnant. I want to know if sperm can still be expelled with a vas deferens blockage.Doctor's answer:
The vas deferens is one of the important reproductive organs in males, responsible for maturing sperm and enabling it to gain motility, as well as serving as a necessary channel for transporting sperm. If this channel becomes blocked, it can hinder the smooth expulsion of sperm outside the body. Therefore, if the vas deferens is blocked, it may result in no sperm being expelled, and timely (: unblocking) is necessary.Vas deferens blockage can lead to obstructive azoospermia, which is often characterized by normal testicular size, texture, and shape, but with no sperm present. In fact, there are many causes of vas deferens blockage, but they typically fall into a few common categories:
1. Congenital malformations. Such as the absence of the head, body, or tail of the epididymis, or a partial or complete absence of the vas deferens, or a lack of connection between the vas deferens and the epididymis, or underdeveloped epididymis, vas deferens, and seminal vesicles. All of these can cause vas deferens blockage. For these conditions, Shanghai Changjiang Hospital of Infertility and Sterility typically uses vas deferens anastomosis or epididymal-vas deferens anastomosis for treatment.
2. Inflammation. Such as epididymitis, orchitis, seminal vesiculitis, or urogenital infections like prostatitis or epididymitis-vas deferens tuberculosis, which can cause duct obstruction and lead to vas deferens blockage, often occurring at the junction of the epididymis and vas deferens. In such cases, initial anti-infection treatment may be administered.
3. Tumors. Common types include epididymal tumors, seminal vesicle tumors, or prostate tumors, all of which can cause vas deferens blockage. Therefore, tumor resection can be an effective treatment.
4. Surgical injury. Such as surgery for epididymal spermatocele or hydrocele of the tunica vaginalis, which may damage the epididymis; surgeries like inguinal hernia repair, varicocele repair, or spermatic cord tumors may injure the vas deferens; prostate surgery can lead to obstruction of the ejaculatory duct. Even if these surgeries do not cause direct damage, postoperative care must be meticulous to avoid infection, adhesion, and scar formation, which can compress and obstruct the duct system.
