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.
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:
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.
The efficacy of the copper pearls is comparable with oral contraceptives, the pill, when used correctly. However, no birth control method is 100% effective. For detailed information about the Copper Pearls please download the patient information leaflet.
If you are looking for long term, hormone free, reversible pregnancy protection please talk to your healthcare provider to find out if you are a candidate for the Copper Pearls.
Since the IUB™ is one third to a half of the size of traditional intrauterine devices, it can be inserted almost painlessly without local anesthesia.
Once the IUB™ is placed in the uterus it forms a 3-dimensional spherical shape.
The IUB™ is available in 3 different sizes ranging from 12 mm to 18 mm in diameter. Your doctor will advise you which size is most suitable for you.
