An IUD/IUS is inserted into the uterus through the cervix.actually everything i have read about the currently used IUDs they are not what you are implying,
they are inserted into the cervix, this causes a buildup of mucus which in turn causes the sperm to not be able to enter into the cervix to journey and meet up with an ovum.
There are two types of IUDs available in the US:
Paragard (Copper T 380A) contains copper

Mirena (contains progestin)

My sources state that currently the primary mechanism of action of IUDs is believed to be the production of an environment that is spermicidal. BUT, if fertilzation does take place, changes in the lining of the uterus would also prevent implantation.
Read the Patient Package Information and Prescribing Information on the two IUDs listed for more information.
Some antibiotics decrease the effectiveness. Are you stating that antibiotics probably result in most unplanned conceptions? I have never read this. It is usually theorized that the woman did not take her pills per instructions.things ingested during the month could also impair the effectivness of the pill one such impairment would be an antibiotic,this probably causes the most “unplanned fertilizations”
the way they are supposed to work is basically to “fool” the body into believing its already Pregnant,
