Good news: contraceptives are more effective than ever (a study explains)

Without a doubt it is a news.

A recent study conducted at the Guttmacher Institute in the United States has concluded that all the contraceptive methods we use today they are more effective than ever and the percentage of error of all of them has been decreasing gradually since 2002.

We know the theoretical effectiveness of the contraceptive options we choose, but from time to time it is convenient for science, in continuous review, to study and, regardless of that margin of theoretical error, analyze how they really work in conditions as close as possible to reality. That is, as we are using them.

And that is precisely what the Guttmacher Institute researchers have done, who have analyzed up to 15,728 one-year intervals using a certain contraceptive method to see how many have ended up in a pregnancy. A study involving 6,683 women from 2006 to 2010.

Researchers have compared the margins of error in these intervals with another previous study conducted between 1995 and 2002. And the great conclusion: they have discovered that the difference between both periods is that error rates have dropped in all cases, from the 14.9% we had in 1995 to a significant 10.3% between 2006-2010.

Of course, not all methods have lowered their margins of error equally, with the pill and IUD having experienced the greatest drops: from 8% in 1995 to 6% in 2006-2010.

Studies like this serve to update indices such as the Pearl Index, which measures the actual effectiveness of various contraceptive methods regardless of its theoretical effectiveness and measured in laboratory conditions. Estimating how they work in reality is really important to help make a decision to what is the method you want to use.
