Efficacy for contraceptives is almost always measured per year. That is, of every 100 couples using this method for a year, two will become pregnant. As the article says, this is about the same level as (perfect use of) condoms.
- Markoff 10y agoseem very inaccurate since every couple has very different frequency of sex per year, some couple can have 100 intercourses, other will have 20 and they have same odds according some average couple?
- scott_karana 10y agoThe inaccuracy would depend on the sample size of the test groups. It might be useful to get standard deviation, or maybe the methodology excludes outliers?
