## **Core Concept**
The minipill, also known as the progestin-only pill (POP), is a form of contraception that contains a small amount of progestogen, in this case, desogestrel. It is used for contraception and works by primarily thickening cervical mucus to prevent sperm penetration. Desogestrel is a third-generation progestin with a high progestogenic activity and low androgenic activity.

## **Why the Correct Answer is Right**
The correct schedule for the minipill containing 75 μg of desogestrel is continuous administration, one pill daily, without a break. This regimen is beneficial because it provides effective contraception while minimizing the risk of estrogen-related side effects, as it does not contain estrogen. The continuous administration helps in maintaining steady levels of the progestogen, ensuring consistent contraceptive efficacy.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option suggests a regimen that is not continuous, which could imply a regimen similar to combined oral contraceptives (with a break) or an inconsistent dosing schedule. This would not be effective for a progestin-only pill like desogestrel, which requires continuous administration to maintain contraceptive efficacy.
- **Option B:** This option implies an inconsistent or incorrect dosing schedule. For desogestrel, consistency is key to prevent ovulation and ensure contraception.
- **Option C:** This option likely suggests a different dosing schedule or interval that does not align with the recommended continuous daily administration of desogestrel for optimal contraceptive effect.
- **Option D:** This option might imply a less frequent administration than required for desogestrel, which could compromise its contraceptive efficacy.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that the progestin-only pill (POP) like desogestrel must be taken at the same time every day to ensure maximum efficacy. Desogestrel-containing pills are unique because they can be taken within a 3-hour window without loss of efficacy, but consistency is still crucial.
