A newly published study that wrapped up two years before the pandemic finds that young people are having less sex in the 21st century. Telephone: 404-718-6785; E-mail: lszucs@cdc.gov.

That doesn't mean it's not accurate -- it is, and I've got the migraine and a pile of paper covered with my chicken scratches to prove it -- but it does mean that these rates are arrived at through math, based on the combined effectiveness rates of single methods, not through specific study or clinical trials of the combined methods. Finally, differences in condom and contraceptive use by sexual risk behaviors reveal that use of preventive strategies is suboptimal among high school students who engage in those behaviors. Analyses were limited to sexually active students (i.e., those who had sexual intercourse with one or more persons during the 3 months before the survey). The Contraceptive Implant + Cervical Barriers = 99.99% effective with perfect use - 99.98% effective with typical use If you want to work out the effectiveness of three methods for yourself, you can! Male Condoms + Withdrawal = 99.92% effective with perfect use - 96.2% effective with typical use Because of these challenges to pregnancy- and STD/HIV-prevention goals, monitoring condom and contraceptive use behaviors among sexually active youths is essential.

Primary contraceptive method was assessed through a separate question, “The last time you had sexual intercourse, what one method did you or your partner use to prevent pregnancy?” Respondents could select only one response from the following list of options: I have never had sexual intercourse; no method was used to prevent pregnancy; birth control pills; condoms; an IUD (such as Mirena or ParaGard) or implant (such as Implanon or Nexplanon); a shot (such as Depo-Provera), patch (such as Ortho Evra), or birth control ring (such as NuvaRing); withdrawal or some other method; or not sure. Fourth, the estimates for highly and moderately effective contraception could be underestimated if respondents viewed a less effective option (i.e., condoms or withdrawal or some other method) as their primary contraceptive method used at last sexual intercourse. While they aren't as effective in perfect use, if we add a backup method to the mix, we can be just as protected or even more protected from pregnancy as we could be with a more effective single method. For example, condom use as the primary pregnancy prevention method was more common among students in grades 9 (55.3%), 10 (47.7%), and 11 (45.3%) versus students in grade 12 (37.4%) (and grade 9 versus grade 11), whereas IUD or implant use was less common among 9th-grade students (<1.0%), compared with students in grades 10 (3.3%), 11 (3.2%), and 12 (8.2%). 12 Factors to Consider When Choosing the Best Birth Control for You.

MMWR Suppl 2020;69(No. Without specific study on these things, we can't predict how much it may reduce the effectiveness of one method in those cases nor account for that possibility in the math. Male Condoms + the Sponge = 99.8% effective with perfect use - 98.0% effective with typical use
