The use of intra - uterine devices ( IUDs ) never take off in the USA as birth control machine , the fashion they did in the eternal sleep of the mankind . But a new field might exchange that .
Researchers track 35 years ’ worth of data and rule that the copper - T is not only an effective long - term birth control tool , but arguably the most in force emergency prophylactic machine there is .

Adoption rates of IUDs only just hit around the 5 % mark in the USA in 2008 . But the eternal sleep of the reality trust on them much more hard : 10 % in the UK , 24 % in France , 43 % of contraceptive - using women in China — and thanks to the 10 + years of giving birth hold in the implant can provide , it ’s also a tremendously democratic one - off operation .
What the great unwashed might not have substantiate is that the intrauterine gadget is also an effective emergency brake birth control gadget . A copper color IUD can be used up to five daylight after intercourse , while the morning after contraceptive pill generally has a windowpane of just 72 - 120 hours depending on the preparation , and is more effective the sooner you get it .
The big difference for the IUD is the pace of effectiveness . The emergency preventative pill broadly has a charge per unit of around 80%+ , meaning 80 % of women who would have gotten pregnant from the sex wo n’t . Various formulations of the oral contraceptive also have consequence where they ’re less in force for mass with higher BMIs . So , how does an IUD heap up ?
A new meta - field of study has analyzed35 years of datafrom 42 field across six countries — an enormous analytic thinking that shows an unbelievable final statistic . For the 7034 vitrine , the pregnancy rate ( barring one outlier field of study ) was just 0.09 % .
These studies were strictly for copper IUDs , and it has n’t been analyse if the same holds true for hormonal one , too . The one Brobdingnagian other vantage for using an IUD as an emergency prophylactic machine is that afterwards , you ’re sorted for a decade of being baby - free — or less , if you get it remove .
So , why is n’t it used more wide ? The two obvious drawbacks are the fact that it ’s well more expensive than Plan B , and also that it requires a medical procedure . you could just cull up some pills at a apothecary’s shop , where an IUD needs to be introduce by a medical pro , a clip - consuming and often expensive procedure .
Nonetheless , this research shows that as an emergency measure , an IUD is very efficacious , and one that ask to be offer more wide .
