Hormone-free contraception with copper
A hormone-free contraception takes advantage of the effects of natural copper. Regardless of the specific product, copper particles are released into the womb. This reacts to the copper, which prevents an egg from nesting and limits the motility of the sperm. Below you will find various hormone-free methods of contraception with copper, which are also an alternative to the pill.
Copper based birth-control is also an ideal hormone-free emergency contraception, which is possible up to 5 days after unprotected sex.

Gold IUDs add a gold alloy that has an antibacterial effect to the copper base material. Copper IUDs and the contraceptive effect usually last 5 years, after which the IUD is removed again.
