Correct answer: BDesogestrel POP inhibits ovulation more consistently than traditional POPs

Desogestrel POP suppresses ovulation more consistently than traditional POPs and has a longer missed-pill window. Traditional POPs act mainly through cervical mucus effects and have a shorter window. Age 30 is not a contraindication, and no POP protects against STIs. The pearl is that not all POPs have the same pharmacological profile.
