Why is the band still pregnant?

First: the word "contraceptive device" may be a little strange to everyone, but you must have heard of "shanghuan". We usually say the "ring" of "shanghuan" refers to the intrauterine device.

Second, they have similar principles of action, both of which achieve contraceptive effect by stimulating the endometrium and interfering with the implantation of fertilized eggs. The former inhibits the metabolism of endometrial cells by releasing copper ions. The latter inhibits endometrial growth by releasing progesterone. It interferes with the implantation of fertilized eggs.

Third: because the intrauterine device is through the endometrium, to prevent the implantation of fertilized eggs to work, so it must be placed at the bottom of the uterus, a large area of contact with the endometrium can be effective contraception. Under normal circumstances, if the contraceptive device is placed in the right position, its contraceptive success rate is very high, basically more than 99%.
