Ligation can be performed at family planning stations or outpatient family planning centers in hospitals.1. In the case of male ligation, the ligation site is mostly the root of the scrotum, a 1-2cm incision is made on the scrotum, and the vas deferens is cut and ligated outside the body after freeing it. Generally, it is necessary to cut and ligate the vas deferens bilaterally to complete the male ligation. 2. For women, a 2-3cm incision is made in the lower abdomen, and then the fallopian tubes are found and ligated bilaterally to complete the ligation surgery. Due to the current medical advancement and the widespread promotion of IUDs, their effects are safe and reliable and avoid incisions, so ligation is rarely performed nowadays. For female patients who need ligation, it is recommended to go to the local family planning service station or the outpatient fertility center of the hospital to ask about ligation.
