Ligation is a form of contraception, and a more complete form of contraception, called tubal sterilization. The fallopian tube is the channel through which the egg and sperm unite and the place where the fertilized egg is formed, and permanent sterilization can be achieved by cutting it. The procedure is a cut and ligation of the fallopian tubes, which can be done either openly through the abdomen or laparoscopically. There are two methods of surgery: firstly, the cramping and embedding method; secondly, the folding and ligation method of the fallopian tubes, and previously there was also a silver clip method of the fallopian tubes, which is less used nowadays because of the high probability of the silver clip falling off. After finding the fallopian tubes, avoiding the blood vessels, successfully cutting both fallopian tubes and ligating the two broken ends, the effect of contraception can be achieved.
