Ligation can also be attached afterwards. For many couples, who are married with children and use other contraceptive measures that may fail, they eventually choose a method like male ligation. Male ligation means that both vas deferens are ligated, so that no sperm will enter the seminal vesicles for storage again and no sperm will be ejaculated into the woman’s vagina during intercourse, making it impossible to cause another pregnancy. If you need to get pregnant again after a ligation, you will need to have surgery to remove the vas deferens from the ligated area and have the vas deferens anastomosed end to end or have a vas deferens epididymal anastomosis so that you can continue to have children.
