A man’s ligation and a woman’s IUD are both very good contraceptives, and should be analyzed on a problem-specific basis. If you don’t have children, a female IUD may be better. If you already have children and do not plan to have more, it may be better for a man to have a ligation. The success rate of IUD is not 100%, while the success rate of contraception for men after IUD is 100%, because it is impossible for men to get pregnant again after IUD, and women may also get pregnant accidentally during IUD. It is also important to note that a woman’s IUD may cause a change in the position of the ring, and there is a higher chance of the ring falling off or contraceptive failure.
