Comment: that's complete BS

The rate of teen pregnancies, and unwanted preganncies amongst those practicing abstinence is zero. if you are having sex, you aren;t practicing abstinence. On the other hand if birth control, properly used is 99% effective, and your average horny teen has sex 100 times per year (probably quite high but who knows) then the birth control will fail at least once per year. Now let's say the average teen is active for age 16-19, and the fertile period is about 4-5 days per month. that puts the odds of a sexually active teen using birth control of getting pregnant pretty high, especially compared to the rate of ZERO amongst those who actually practice abstinence.
