Use of LARC methods by children of child-bearing age in the state increased to 20% during the 2009–2014 period. [33] [34] A 2017 study found that CPFI "reduced the teen birth rate in counties with clinics receiving funding by 6.4 percent over five years.

[8] [10] Oxidation occurs primarily at the C2α and C16β positions, while reduction occurs in the A ring. [10] 5α-Dihydrolevonorgestrel is produced as an active metabolite of levonorgestrel by 5α-reductase. [8] The elimination half-life of levonorgestrel is 24 to 32 hours, although values as short as 8 hours and as great as 45 hours have ...
In fact, between 1970 and 2012 this has resulted in a 25% increase of child poverty rates. One study also concluded that if women under the age of 30 began using birth control pills as a preventative measure against unplanned pregnancies, the child poverty rate could drop around half a percentage point within a year. [81]
The TCu 380A (Paragard) has a one-year failure rate of 0.8% and a cumulative 12-year failure rate of 2.2%. [10] Over 12 years of use, the models with less surface area of copper have higher failure rates. The TCu 220A has a 12-year failure rate of 5.8%. The frameless GyneFix has a failure rate of less than 1% per year. [14]
