Which of the following is a PROGESTIN-ONLY contraception option?

• A. Progestin-only pills
• B. Ring
• C. Patch
• D. Oral contraceptives

Answer: (A)

The key idea is that progestin-only contraception uses a progestin without estrogen. Among common methods, the mini-pill delivers only progestin, whereas the ring and the patch release both estrogen and progestin, and most oral contraceptives are combination products containing estrogen with progestin. So the progestin-only pill is the correct choice. Progestin-only pills prevent pregnancy mainly by thickening cervical mucus and thinning the endometrium, and they are particularly useful for people who cannot take estrogen (such as those who are breastfeeding or have certain cardiovascular risks). They require strict adherence to daily dosing because missing doses more readily reduces their effectiveness compared with combination pills.
