How does the IUD birth control work?

Answer 1

IUD sits in the uterus and prevents implantation of a fertilized egg.
It thickens the cervical mucus, It changes the lining of the uterus, and It lessens the likelihood of ovulation

all of the above !!!!!!!
No, the IUD does not work by causing abortion. It affect the ability of sperm to get to the egg.

Answer 2

An intrauterine device (IUD) is a metal or plastic object that is placed in to a woman's uterus to prevent pregnancy. We believe that it works by preventing implantation of the fertilized egg.

Advantages include that it is effective, does no require the woman to actively do anything for it to work or plan ahead, it is reversible, and it does not have to use hormones if they are no desired (some are treated with hormones).

Disadvantages include that it can cause injury to the uterus, if a pregnancy does occur it is more likely to be ectopic (outside the uterus) and that is not only provides to protection from STD's but rather makes them more likely to ascend into the abdominal cavity if they are acquired.

It is considered a good option for women in stable relationships (usually meaning married) who desire reversible contraception. It is usually not considered appropriate for women who should also be using protection from STD's.

Answer 3

An IUD is a T-shaped contraceptive device that is inserted into the uterus. IUDs primarily work by disrupting sperm mobility and damaging sperm so that they are prevented from joining with an egg.

Answer 4

The IUD Birth Control is a small T-shaped device that is inserted into the uterus to prevent pregnancy. What it does is that it basically blocks the sperm from ever reaching the egg, and if it cannot do that, then there is no way to get pregnant.

Answer 5

The copper IUD releases copper into the uterus, which works as a spermicide. The others release a form of the hormone progestin into the uterus. The progestin thickens the cervical mucus so that sperm can't reach the egg.

Answer 6

The copper IUD interferes with sperm's ability to fertilize an egg. The progestin-containing IUD makes it difficult for sperm to get to the egg.

Answer 7

The IUD, or intraiuterine device, prevent pregnancy. The hormone-bearing IUD can also decrease the symptoms of heavy or painful periods.
