The vas deferens are a pair of curved thin tubes that run parallel to the ureter and open at the back end to the cloaca. The vas deferens are crucial for male friends, as they are related to the next generation of male friends. Many men suffer from infertility due to blocked vas deferens.
Azoospermia can be caused by complete blockage of bilateral vas deferens (from testicular rete to ejaculatory tube) for any reason. According to statistics, obstructive azoospermia accounts for about 55% of the causes of azoospermia.
The causes of male vas deferens obstruction
Many reasons can cause obstruction of the vas deferens and lead to male infertility:
Congenital abnormalities: Congenital undeveloped vas deferens, lack of communication with the epididymis, often accompanied by underdeveloped seminal vesicles, resulting in low semen volume and azoospermia.
Inflammatory stenosis: various germs cause inflammation of vas deferens, forming scars, resulting in obstruction of the lumen, and even azoospermia in severe cases.
Tumor: tumor from vas deferens itself or adjacent organs oppresses the lumen and causes obstruction, which is also one of the reasons for azoospermia.
Other: Trauma or surgical injury, such as hernia repair surgery, resulting in lumen obstruction.
Treatment methods for male vas deferens obstruction
1. Ejaculatory duct edema caused by reproductive tract infection generally does not require surgery. After anti infection and physical therapy to control inflammation, the edema subsides, and the reproductive tract can be restored to patency.
If the obstruction is in the vas deferens, resection of the obstructed segment and end-to-end anastomosis of the vas deferens can be performed.
3. If the obstruction is in the tail of the testicle, a vasectomy epididymostomy can be performed.
4. Sperm cords, seminal vesicles, prostate tumors or cysts can be surgically removed.
5. For those with underdeveloped vas deferens, artificial seminal vesicles can be used to collect sperm from the epididymis and then undergo artificial insemination to solve fertility problems.
How to prevent and control blocked vas deferens
1. In daily life, pay attention to personal hygiene, and it is recommended to clean private areas every day to prevent the infection of various pathogens.
2. Stay away from dangerous factors such as radiation pollution, chemical pollution, hormone effects, viral infections, environmental pollution, etc.
3. Quit smoking and drinking, and eat less greasy and spicy food.
4. Do not cycle, take a hot bath, wear jeans, etc. for a long time to avoid high testicular temperature that affects sperm production.
If there are diseases such as hernia and varicocele, it is recommended to choose a reputable hospital for surgery to avoid damage to the vas deferens due to improper surgery.
Expert reminder: Men need to use their index finger and thumb to gently squeeze and examine the testicles, paying attention to whether there is epididymal induration and accumulation caused by blocked vas deferens. If such signs are found, please seek medical attention at the hospital and undergo a vas deferens angiography to understand the patency of blocked vas deferens.
