Hormone free contraception


The copper pearls are a birth control method that requires no hormones and is effective for up to 5 years. The Copper Pearls works along the same principle as other intrauterine devices and prevents pregnancy locally - within the uterus. The contraceptive effect comes mainly from the copper.

The copper pearls consist of a special shape memory alloy, which has been successfully used in medicine for a long time, e.g. in implants and stents. Several copper pearls are strung on a uterus friendly frame, coated with polymer.

how do the copper pearls work

As soon as the Copper Pearls is placed in your uterus, it starts releasing small amounts of copper into your uterus to provide continuous birth control for up to 5 years.


The method of action is similar to standard copper intrauterine devices. The copper ions released probably:

  • interfere with the process of fertilization in the uterus 
  • limit the sperm mobility
  • prevent sperm from fertilizing the egg
  • prevent the egg from attaching (implanting) in the uterus

The amount of copper released from the copper pearls is minimal - the average quantity of copper ingested with a normal diet is much higher than the quantity inserted to the body through the copper pearls.
