Male sterilization procedures are mainly vasectomy and can be divided into two main categories: obstructive sterilization and non-obstructive sterilization. Obstructive vasectomies include vasectomies, chemical blockages of the vas deferens, and other vasectomies. Non-obstructive sterilization includes the use of vasovaginal filtration devices or injection of maleic anhydride copolymer. 1. Vasectomy: belonging to the obstructive vasectomy, it is the more commonly used procedure in the clinic, and the operation is to rely on the steel wire in the vas deferens ligation of two channels. The main advantage lies in the easy operation and few complications, which is favorable to the patients who want to conceive again in the future. 2. Vasectomy with chemical blockage: this procedure mainly uses scrotal puncture to inject chemical blocking agent into the vas deferens. This method is safer as there is no need to remove the vas deferens. 3. Non-obstructive vasectomy: This includes intravesical filtration devices such as nylon filters and injection of maleic anhydride copolymers, etc. It is less commonly used in clinical practice and is not the preferred method. The type of sterilization procedure used for different patients varies according to the patient’s physical condition and self-will, and the patient should go to a regular hospital for consultation and implementation of the procedure.
