Sorry, incorrect. The IUD prevents IMPLANTATION of a fertilized egg. It does nothing to prevent fertilization.
Fertilization occurs in the fallopian tube. An IUD is placed in the uterus to prevent implantation. Think of them as mini coat-hangers.
Birth control pills and the IUD work on two levels. The first is to prevent conception. However if conception does occur, there is a fail-safe that raises the effectiveness of the pill or device. The lining of the womb is thinned and made hostile to the fertilized egg. The fertilized egg does not implant in the womb as it normally would, but rather continues to fall..........to death. Read the information provided in the pill prescription. Or do a yahoo or google search using the term abortifacient. You’ll find tons of information.
The "misinformation" is entirely yours, actually.
An IUD never prevents fertilization. It works by creating an inflammatory response inside the uterus that prevents implantation of the developing baby AFTER fertilization, which is to say that it causes an early abortion every time conception occurs.
The pill (and other hormonal contraceptives) essentially simulates pregnancy. Part of the time it prevents ovulation, and therefore prevents fertilization. But the rest of the time, ovulation (called "breakthrough ovulation"; Google it) occurs and implantation fails because the lining of the uterus is in "pregnancy mode," not "implantation mode" ... again, that's an early abortion.
(Read the package insert for any hormonal contraceptive if you don't believe me. They all mention this.)
check the Planned Parenthood website on how the pill, patch and IUD work. In most situations, a contraceptive will stop the egg from being released or kill the sperm. However, if all that fails, the emergency brake is how these affect the lining of the womb preventing implantation. Again, it’s what’s on the planned parenthood website.
This is the intention of the pill but it often fails. As a backup it prevents implantation of the fertilized egg. This would be an abortion. How often this secondary action occurs is open to debate. But it is fair to say that the pill is abortifacient. I encourage more knowledgeable readers to make my statements more precise.
An IUD before sex prevents fertilisation and is not abortion.
The primary action of an IUD is to prevent implantation of a fertilized egg. The IUD is primarily abortifacient.
