Contraception and Family Planning

Contraception and Family Planning Indian Medical PG Question 1: What is the best index of contraceptive efficacy?

• A. Pearl index (Correct Answer)
• B. Quetelet index
• C. Broca index
• D. Chandelier's index

Contraception and Family Planning Explanation: ***Pearl index*** - The **Pearl Index** (also known as the Pearl Rate) is the most common measure of contraceptive efficacy, representing the number of unintended pregnancies per 100 woman-years of exposure. - It considers both the duration of use and the number of women-months a contraceptive method is used, providing a standardized way to compare different methods. *Chandelier's index* - **Chandelier's index** is not a recognized or standard measure for contraceptive efficacy in scientific literature or clinical practice. - This term does not correspond to any known medical or statistical index for evaluating contraceptive methods. *Quetlet index* - This is likely a misspelling or incorrect reference to the **Quetelet index**, which is another name for the **Body Mass Index (BMI)** used to assess body fat based on height and weight. - The **Quetelet index/BMI** has no relevance to measuring contraceptive efficacy. *Broca index* - The **Broca index** is a historical method for assessing ideal body weight based on height, often used in older anthropometric studies. - It is not used to measure contraceptive efficacy or any other aspect of reproductive health.

Contraception and Family Planning Indian Medical PG Question 2: Which of the following is not a long-acting reversible contraceptive method?

• A. Combined oral contraceptives (Correct Answer)
• B. Implanon
• C. Copper T
• D. Depo-Provera injection

Contraception and Family Planning Explanation: ***Combined oral contraceptives*** - While effective, **combined oral contraceptives** require daily adherence and are not typically classified as long-acting due to their need for frequent, consistent administration. - Their mechanism involves **exogenous hormones** that suppress ovulation and thicken cervical mucus, but their contraceptive effect relies on continuous daily intake. *Implanon* - **Implanon** (etonogestrel implant) is a **subdermal contraceptive implant** that provides effective contraception for up to three years. - It works by slowly releasing progestin, making it a **long-acting reversible contraceptive (LARC)**. *Copper T* - The **Copper T intrauterine device (IUD)** is a non-hormonal LARC that can prevent pregnancy for **up to 10 years**. - It acts by creating an inflammatory reaction in the uterus that is toxic to sperm and eggs, preventing fertilization. *Depo-Provera injection* - The **Depo-Provera injection** (medroxyprogesterone acetate) is a progestin-only contraceptive given every **3 months**. - While it offers extended protection, it is **not universally classified as a LARC** by major guidelines (WHO, ACOG, CDC), which typically reserve this designation for IUDs and implants that do not require regular clinic visits.

Contraception and Family Planning Indian Medical PG Question 3: Which one of the following IUDs is associated with a low pregnancy rate (0.2 per 100), less number of ectopic pregnancies and lower menstrual blood loss?

• A. Cu T-380A
• B. ML-Cu 375
• C. LNG-20 (Mirena) (Correct Answer)
• D. Progestasert

Contraception and Family Planning Explanation: ***LNG-20 (Mirena)*** - This **levonorgestrel-releasing IUD** (Mirena) has a very low pregnancy rate (0.2 per 100 women-years). - It significantly **reduces menstrual blood loss** and cramps and is associated with a lower risk of ectopic pregnancies compared to copper IUDs because it thins the endometrial lining, making implantation less likely. *Cu T-380A* - The **Cu T-380A copper IUD** has a slightly higher pregnancy rate (around 0.6-0.8 per 100 women-years) compared to Mirena. - It is known to **increase menstrual blood loss** and dysmenorrhea, which is contrary to the question's criteria. *ML-Cu 375* - The **Multiload Cu 375** is another type of copper IUD, with a pregnancy rate similar to or slightly higher than the TCu-380A. - Like other copper IUDs, it typically **increases menstrual flow** and may worsen menstrual pain. *Progestasert* - **Progestasert** was an early progesterone-releasing IUD that had a higher failure rate and a shorter lifespan (1 year) compared to newer LNG-IUDs. - While it aimed to reduce menstrual blood loss, its **overall efficacy and duration of action** were inferior to the LNG-20 system.

Contraception and Family Planning Indian Medical PG Question 4: For a woman who has had unprotected intercourse two days ago, which one of the following emergency contraceptive methods is LEAST preferred as first-line emergency contraception?

• A. Levonorgestrel 1.5 mg
• B. LNG IUD
• C. Yuzpe regimen (Correct Answer)
• D. Ulipristal acetate

Contraception and Family Planning Explanation: ***Yuzpe regimen*** - The **Yuzpe regimen** uses higher doses of combined oral contraceptive pills, leading to more side effects like nausea and vomiting and generally lower efficacy compared to newer methods. - It involves taking two doses of estrogen and progestin, making it less convenient and less effective, especially after **48 hours**, compared to progestin-only or ulipristal acetate pills. *Levonorgestrel 1.5 mg* - **Levonorgestrel (LNG)** 1.5 mg, taken as a single dose, is a highly effective and widely recommended first-line emergency contraceptive within **72 hours** of unprotected intercourse. - It primarily works by **inhibiting or delaying ovulation**, without causing significant side effects in most women. *LNG IUD* - While an **LNG IUD** can be used as emergency contraception, it is not typically considered a first-line *oral* method; it is placed by a healthcare provider and can provide long-term contraception. - It is effective if inserted within **5 days** of unprotected intercourse, making it a highly effective option that also offers ongoing contraception. *Ulipristal acetate* - **Ulipristal acetate (UPA)** is a highly effective emergency contraceptive, even up to **120 hours (5 days)** after unprotected intercourse. - It works by delaying or inhibiting ovulation and is generally more effective than levonorgestrel, especially when taken more than **72 hours** post-coitally.

Contraception and Family Planning Indian Medical PG Question 5: Which of the following are examples of LARC (Long Acting Reversible Contraceptives) ? 1. Copper-T 380A 2. Implants 3. LNG-IUS Select the correct answer using the code given below :

• A. 1, 2 and 3 (Correct Answer)
• B. 1 and 3 only
• C. 1 and 2 only
• D. 2 and 3 only

Contraception and Family Planning Explanation: ***1, 2 and 3*** - **Long-acting reversible contraceptives (LARCs)** include all methods that are effective for an extended period, do not require daily attention, and are reversible. The **Copper-T 380A intra-uterine device (IUD)**, **subdermal implants**, and the **levonorgestrel-releasing intra-uterine system (LNG-IUS)** all fit this description. - These methods are highly effective due to minimal user error and provide contraception for several years, making them ideal for long-term birth control. *1 and 3 only* - This option incorrectly excludes **implants**, which are a well-established and highly effective form of LARC, offering contraception for up to three years. - While Copper-T 380A and LNG-IUS are indeed LARCs, the exclusion of implants makes this option incomplete. *1 and 2 only* - This option incorrectly excludes the **levonorgestrel-releasing intra-uterine system (LNG-IUS)**, which is an increasingly popular and effective LARC, providing contraception for up to five years. - The LNG-IUS is a hormonal LARC often used for both contraception and managing heavy menstrual bleeding. *2 and 3 only* - This option incorrectly excludes the **Copper-T 380A IUD**, which is a non-hormonal LARC. - The Copper-T 380A is one of the most widely used LARCs globally, offering highly effective contraception for up to ten years.
