Abstract in brief

  • The review updates estimates of the likelihood that different contraceptive methods will fail within the first year of use in the U.S., comparing typical use (which includes mistakes and inconsistent use) with perfect use (correct and consistent use).
  • It highlights how the failure rates differ based on the method's sensitivity to imperfect use and the difficulty of using it correctly, showing the impact of user behavior on effectiveness.
  • The new data incorporate recent research findings, providing a more accurate understanding of contraceptive failure rates during both typical and perfect use.]

@MorgLaMignonne Because of the times that contraception fails (which literature sites as rare), it is still more likely to fail in Black women (15% v 8%). (Sundaram A, et al. Contraceptive Failure in the United States: Estimates from the 2006-2010 National Survey of Family Growth.)

Demorei 15 min pra achar uma fonte confiável, com metodologia, que justifique a eficácia da camisinha masculina. Os melhores estudos geralmente citam trussel2011. TL;DR 98% com uso perfeito, 87% com uso comum. https://t.co/eVdsoIpsIm

@oyaziMK2 避妊は基本的に確率論なのでこれさえやればOKってこともないですし適用可能かどうかは医者の判断によりますけど、その確率論で言うなら『コンドームって実は避妊効果は思ったより低いし何なら膣外射精と変わらんレベル』なのでこっちの過信の方が危険なんすよね。https://t.co/uWzJY9Po6L

@HoParlato @_elle_gal_ @carmelodipaola sto leggendo lo studio https://t.co/7msz2u3JeB (ho l'accesso completo dall'università), riguarda solo gli USA ed è un po' datato, avrei anche qualche perplessità sul calcolo delle percentuali, ma devo finire di leggerlo.

@SirenStephR @HuffPost According to “Contraceptive Failure in the United States: Estimates from the 2006–2010 National Survey of Family Growth,” by Aparna Sundaram of the Guttmacher Institute et al., within the first 12 months of typical use, long-act (the IUD and implant) have the lowest failure rates
