Which of the following are benefits of using long-acting reversible contraceptives (LARCs)? Select all that apply.
High efficacy (>99%)
Requires daily adherence
Reversible upon removal
Protects against STIs
Suitable for adolescents
Correct Answer : A,C,E
Long-acting reversible contraceptives (LARCs) include intrauterine devices (IUDs) and subdermal implants. They provide extended contraception without user action, lasting from 3 to 10 years depending on type. They are highly effective, with failure rates <1%, and are reversible upon removal, allowing rapid return to fertility. LARCs do not protect against STIs, and barrier methods are still required. They are suitable for adolescents, with no age restrictions. Normal menstrual cycle length is 21–35 days; LARCs may alter bleeding patterns but do not affect systemic hormone levels significantly.
Rationale for correct answers
1. LARCs have efficacy >99%, with failure rates <1% per year. This is due to minimal user dependency and continuous hormone or copper release. Their effectiveness surpasses that of pills, patches, or rings.
3. LARCs are reversible upon removal. Fertility typically returns within days to weeks. This reversibility distinguishes them from permanent methods like sterilization.
5. LARCs are suitable for adolescents. They are safe, effective, and recommended by major guidelines including ACOG and WHO. They reduce unintended pregnancy rates in this population.
Rationale for incorrect answers
2. LARCs do not require daily adherence. This is a major advantage over oral contraceptives, which have typical-use failure rates of 7% due to missed doses. LARCs eliminate user error.
4. LARCs do not protect against STIs. They prevent pregnancy but offer no barrier to pathogens. Condoms remain necessary for STI prevention, especially in high-risk populations.
Take home points
- LARCs are >99% effective and user-independent.
- They are reversible and fertility returns quickly after removal.
- Adolescents can safely use LARCs.
- LARCs do not protect against STIs; condoms are still needed.

Correct Answer is B
Explanation
Adolescentsrequire tailored contraceptive counseling due to high rates of unintended pregnancy, variable adherence, limited knowledge, and developmental factors. They often face barriers such as lack of access, confidentiality concerns, and misinformation. The adolescent pregnancy rate remains significantly higher than other age groups, with unintended pregnancy rates exceeding 80% in some populations. Normal menstrual cycles may be irregular in early adolescence, complicating fertility awareness methods. Cognitive and emotional maturity also influences decision-making and consistency in contraceptive use. Long-acting reversible contraceptives (LARCs) are recommended due to their high efficacy and low maintenance.
Rationale for correct answers
2.Adolescents have the highest rates of unintended pregnancy due to inconsistent contraceptive use, limited access, and developmental factors. Tailored counseling improves method selection, adherence, and understanding, reducing risk.
Rationale for incorrect answers
1.Postmenopausal women are not at risk of pregnancy due to cessation of ovulation. Their counseling focuses on hormone replacement therapy and other health concerns, not contraception.
3.Women over 50 years typically have declining fertility due to reduced ovarian reserve and anovulatory cycles. While contraception may be needed until menopause is confirmed, their risk of unintended pregnancy is much lower than adolescents.
4.Nulliparous women may have specific considerations for method selection (e.g., IUD insertion technique), but they do not inherently have higher unintended pregnancy risk. Counseling may be individualized but not necessarily tailored due to elevated risk.
Take home points
- Adolescents have the highest unintended pregnancy risk
- Tailored counseling improves contraceptive adherence and understanding
- Postmenopausal and older women have low fertility risk
- Nulliparity affects method choice, not pregnancy risk
Correct Answer is B
Explanation
Depot medroxyprogesterone acetate (DMPA)is a progestin-only injectable contraceptiveadministered every 12 weeks. It works by inhibiting ovulation, thickening cervical mucus, and altering the endometrium. A common and important side effect is delayed return to fertility, with ovulation resuming on average 9–10 months after the last injection. DMPA also causes menstrual irregularities, including amenorrhea. It may reduce bone mineral density with long-term use; normal bone mineral density (BMD) values are ≥1.0 g/cm². DMPA does not increase thromboembolic risk and is safe for women with estrogen contraindications. Other side effects include weight gain and mood changes.
Rationale for correct answers
2.DMPA is associated with a delayed return to fertility, often taking 9–10 months after the last injection for ovulation to resume. This is a well-documented and important counseling point for users considering future pregnancy.
Rationale for incorrect answers
1.DMPA does not cause a significant increase in libido. In fact, some users report decreased libido or mood changes. Libido effects vary and are not a consistent or prominent side effect.
3.While DMPA does not increase the risk of venous thromboembolism, this is not a side effect but rather a safety advantage. It is suitable for women with contraindications to estrogen, but the question asks for a side effect.
4.DMPA often causes unpredictable menstrual cycles, especially in the first year. Many users experience irregular bleeding or amenorrhea. Predictable cycles are not a feature of DMPA use.
Take home points
- DMPA delays return to fertility after discontinuation
- Menstrual irregularities are common with DMPA
- DMPA is safe for women with estrogen contraindications
- Bone density loss is a concern with long-term use
