Question

Based on the chart, what are the three most effective methods to protect against pregnancy?

IUD, implant, injection
patch, vaginal ring, implant
patch, vaginal ring, pill
vaginal ring, patch, injection

Answer 1

IUD, implant, injection
Step-by-step explanation:
According to the CDC, vaginal rings (like NuvaRing) lead to unintended pregnancy in 9% of women who report typical use within the first year of use and 0.3% of women who report perfect use.

Implants (like Implanon) lead to unintended pregnancy in 0.05% of women reporting both typical and perfect uses.

Contraceptive patches (like Evra patch) lead to unintended pregnancy in 9% of women reporting typical use and 0.3% of women with perfect use.

Intrauterine devices (IUDs, like ParaGard and Mirena) have an average of 0.5% rate of unintended pregnancy with typical use and 0.4% rate with perfect use.

The contraceptive injections (like Depo-Provera) have a 6% unintended pregnancy rate with typical use and a 0.2% for perfect use.

Finally, the contraceptive pill yields rates of 9% with typical use and 0.3% with perfect use.

So with perfect use, the most effective methods are implants first, then injections, and then IUDs.
