How to perform male sterilization surgery

Women have to endure a lot of pain during childbirth. Although many men cannot feel their wives’ pain, they still love their wives psychologically. When they don’t want to have children, for various reasons, many men will choose not to allow their wives to undergo sterilization and instead let themselves do it. Many people are curious: How is sterilization performed for men?

Basic principles of ligation surgery

Before you learn about male sterilization, it is important to understand the basic principles of male sterilization. Female pregnancy before sterilization is based on the transport of male sperm to the female vagina through the ejaculatory duct. So, sterilization is to cut off the ejaculatory duct that transports male sperm from the male testicles to the male genitals, so that male sperm cannot enter the semen, thereby preventing male sperm from being ejaculated into the vagina.

How to perform male vasectomy

Procedure 1: Touch and penetrate the vas deferens. Disinfect the surgical field three times with warm 0.1% benzalkonium bromide solution (1:1000 new gentamicin solution) and cover the hole with a towel. Use the thumb and middle thumb of the right hand to find the ejaculatory duct at the front of the scrotum, and squeeze it firmly into the subcutaneous tissue, touch and squeeze the firm ejaculatory duct. Apply local anesthesia to the skin where the ejaculatory duct is fixed, and push the medicine while inserting the needle, so that the medicine diffuses from the skin to the periphery of the ejaculatory duct.

Procedure 2: Immobilize the ejaculatory duct. Use a small sharp knife to make a small incision from the local anesthesia needle hole. The incision length should not exceed 0.4cm. Separate the ejaculatory duct and fix the ejaculatory duct directly through the ejaculatory duct. Separate it slightly along the longitudinal axis of the ejaculatory duct. Then insert the ejaculatory duct fixation clamp into the incision, pinch the ejaculatory duct and pass it out of the incision.

Process 3: Separate the tunica vaginalis and blood vessels of the ejaculatory duct. Use mosquito forceps to separate the tunica vaginalis and blood vessels of the ejaculatory duct. After the ejaculatory duct is excised 1-1.5cm, use two mosquito forceps to clamp the ejaculatory duct on the left and right sides of the separated section, and then remove the fixed forceps.

Process 4: Cut and ligate the part of the ejaculatory duct that is mineralized with hemostatic forceps. After twisting with hemostats, use No. 1 thread to ligate both sides of the operation, 1.5cm apart, lift the ligation thread and cut off about 1cm of the ejaculatory duct, check for bleeding, cut the ligation thread, and use the fascia of the outer muscle of the spermatic flexor to protect the separated broken end with the distal side, and then put it into the skin wound, carefully activate blood circulation, the skin wound does not need sutures, but the two ends of the skin edge must be aligned.

Process 5: Repeat the above process to solve the ejaculatory duct on the other side. After the operation, cover the wound with sterile gauze and fix it with tape.

Male sterilization can be described as a minimally invasive surgery, with a shorter recovery time, relatively lower risks, and less likely to affect male sexual function.
