That is not how an IUD works. What an IUD do is to stop an egg from attaching to the inside of the uterus. It had no effect on the sperm. But no, it shouldn't hurt.
Yep... Copper kills sperm...
An IUD doesn't affect how long semen (or sperm) stays in the uterus. The copper IUD interferes with sperm mobility, lowering the odds of pregnancy. The progesterone IUD thickens the cervical mucus, making it difficult for the sperm to meet the egg.
The Copper IUD is not a store but a contraceptive product. It is an Inter Uterine Device that is inserted in the uterus and prevents the mobility of sperm by the release of ions.
Spermicide works by killing sperm. The copper IUD works by interfering with sperm motility.
A Multiload IUD is a copper IUD.
The ParaGard IUD is T shaped and it contains copper.
Allergy to copper or Wilson's disease are contraindications to the copper IUD that don't apply to the levonorgestrel IUD.

No. Birth control pills work by altering the estrogen, and progesterone hormones in women. Essentially, it tricks her body into thinking she's already pregnant, so she will stop ovulating. The only thing that kills sperm is spermicide and even that doesn't kill them ALL and isn't 100% effective. The copper IUD affect sperm mobility to keep sperm from reaching the egg.
No, Mirena is a plastic IUD containing progestin. The copper IUD on the market in the US is Paragard.
Fertility returns to your baseline after removal of the IUD. Whether it's easy to get pregnant after removal depends on your fertility, not the IUD.
Leaving the copper IUD in longer than you are meant to is not dangerous and will not cause illness.
A copper IUD will not delay your period. The same things can cause a delayed period in women with or without the copper IUD. These include pregnancy and hormonal fluctuations.
The copper IUD does not change pigmentation. If you have an excess of copper (WIlson's disease), the disease could cause change in pigmentation, and the IUD could worsen that. Talk with your health care provider about your particular situation.
