Contraception and Family Planning Indian Medical PG Practice Questions and MCQs

Question 161: A 23-year-old woman desires a combined oral contraceptive for pregnancy protection. Which of the following factors would lead a health professional to recommend an alternative form of contraception?

A. Evidence of hirsutism
B. Presence of fibroids
C. History of pelvic inflammatory disease
D. History of migraine headache that is well controlled by sumatriptan (Correct Answer)

Explanation: **Explanation:** The correct answer is **D (History of migraine headache)**. The use of Combined Oral Contraceptive Pills (COCPs) is contraindicated in women with migraines due to a significantly increased risk of **ischemic stroke**. According to the WHO Medical Eligibility Criteria (MEC): * **Migraine with aura:** MEC Category 4 (Absolute contraindication) at any age. * **Migraine without aura:** MEC Category 4 if age ≥35; MEC Category 3 if age <35. The use of sumatriptan indicates a diagnosis of migraine, and the estrogen component in COCPs further exacerbates the pro-thrombotic risk in these patients. **Why the other options are incorrect:** * **A. Evidence of hirsutism:** COCPs are actually a **first-line treatment** for hirsutism (e.g., in PCOS). They increase Sex Hormone Binding Globulin (SHBG), which lowers free testosterone levels. * **B. Presence of fibroids:** COCPs are not contraindicated in patients with fibroids. In fact, they are often used to manage the heavy menstrual bleeding (menorrhagia) associated with them. * **C. History of Pelvic Inflammatory Disease (PID):** A history of PID is not a contraindication for COCPs. COCPs may actually provide a protective effect against PID by thickening cervical mucus, which prevents the ascent of pathogens. **High-Yield Clinical Pearls for NEET-PG:** * **MEC Category 4 (Absolute Contraindications for COCPs):** Smoker >35 years (≥15 cigarettes/day), History of DVT/PE, Ischemic heart disease, Stroke, Breast cancer (current), Decompensated Cirrhosis, and Migraine with aura. * **Non-contraceptive benefits of COCPs:** Reduced risk of Ovarian and Endometrial cancers (protective effect lasts years after discontinuation). * **Drug Interactions:** Rifampicin and anti-epileptics (Phenytoin, Carbamazepine) induce hepatic enzymes and decrease COCP efficacy.

Question 162: The combined oral contraceptive pill is absolutely contraindicated in:

A. History of thromboembolism (Correct Answer)
B. Pelvic inflammatory disease
C. Age above 40 years
D. Leiomyoma

Explanation: **Explanation:** The **Combined Oral Contraceptive Pill (COCP)** contains estrogen, which increases the hepatic synthesis of clotting factors (II, VII, IX, and X) and decreases anticoagulant levels (Protein S and Antithrombin III). This induces a hypercoagulable state. **1. Why Option A is Correct:** A **history of thromboembolism** (DVT or Pulmonary Embolism) is a **WHO Medical Eligibility Criteria (MEC) Category 4** contraindication (absolute contraindication). Since the estrogen component significantly elevates the risk of recurrent thrombotic events, COCPs are strictly prohibited in these patients. **2. Why the other options are incorrect:** * **B. Pelvic Inflammatory Disease (PID):** COCPs are not contraindicated in PID. In fact, they may offer a protective effect by thickening cervical mucus, which prevents the upward migration of pathogens. * **C. Age above 40 years:** Age alone is not a contraindication. However, it becomes a contraindication if combined with smoking (≥15 cigarettes/day) or other cardiovascular risk factors. * **D. Leiomyoma:** COCPs are not contraindicated and are often used to manage the heavy menstrual bleeding associated with fibroids. **NEET-PG High-Yield Pearls:** * **Absolute Contraindications (MEC 4):** Undiagnosed vaginal bleeding, pregnancy, history of thromboembolism, stroke, ischemic heart disease, active liver disease/tumors, breast cancer, and smokers >35 years old (≥15 cigarettes/day). * **Best Contraceptive for a Lactating Mother:** Progesterone-only pills (POPs) or Centchroman (Saheli), as estrogen suppresses lactation. * **Non-contraceptive benefit:** COCPs reduce the risk of Ovarian and Endometrial cancers.

Question 163: What is the best index for measuring the efficacy of contraception?

A. Pearl Index
B. Life Table Analysis (Correct Answer)
C. Couple protection rate
D. None of the above

Explanation: ### Explanation The efficacy of a contraceptive method is measured by its failure rate. While multiple indices exist, **Life Table Analysis** is considered the superior and most accurate method. **1. Why Life Table Analysis is the Correct Answer:** Unlike other methods, Life Table Analysis calculates the **cumulative failure rate** at specific intervals (e.g., 12, 24, or 36 months). It accounts for "loss to follow-up" and varying durations of use among participants. By calculating the probability of pregnancy for each month of use, it provides a more scientifically rigorous and longitudinal view of contraceptive effectiveness compared to a simple ratio. **2. Analysis of Incorrect Options:** * **Pearl Index (Option A):** This is the most *commonly* used index, but not the *best*. It is defined as the number of unintended pregnancies per 100 woman-years of exposure. Its main drawback is that it assumes a constant failure rate over time, whereas, in reality, the risk of failure is highest in the first few months of use and decreases over time. * **Couple Protection Rate (Option C):** This is a **process indicator** used by national family planning programs to monitor the proportion of eligible couples protected by any modern contraceptive method. It measures program coverage and prevalence, not the clinical efficacy of a specific contraceptive. **3. NEET-PG High-Yield Pearls:** * **Pearl Index Formula:** (Total Accidental Pregnancies × 1200) / (Total months of exposure). * **Most Effective Contraceptive:** Implants (Etonogestrel) have the lowest Pearl Index (~0.05). * **Hierarchy of Efficacy:** Life Table Analysis > Pearl Index. * **Contraceptive Prevalence Rate (CPR):** The percentage of currently married women (15-49 years) who are using any method of contraception. In India (NFHS-5), the CPR is approximately 67%.

Question 164: A woman using oral contraceptive pills misses 3 pills during the third week of her cycle. What is the recommended course of action?

A. Continue taking the pills from the current pack.
B. Take all missed pills along with the next scheduled pill and continue the pack.
C. Start a new pack of oral contraceptive pills immediately.
D. Finish only the remaining hormonal pills in the current pack and start a new pack the next day. (Correct Answer)

Explanation: ### Explanation The management of missed Combined Oral Contraceptive (COC) pills depends on the **number of pills missed** and the **week of the cycle**. This question follows the WHO Medical Eligibility Criteria (MEC) guidelines for "3 or more missed pills." **Why Option D is Correct:** When 3 or more pills are missed during the **third week** (days 15–21), the hormone-free interval (placebo week) must be eliminated to prevent "escape ovulation." The drop in hormone levels from missed pills, combined with the upcoming scheduled placebo break, allows Follicle Stimulating Hormone (FSH) to rise, leading to follicular development. Therefore, the patient should finish the active (hormonal) pills in the current pack and **skip the placebo pills**, starting the next pack immediately the following day. **Analysis of Incorrect Options:** * **Option A & B:** Continuing the pack as usual or taking all missed pills at once is incorrect. Taking more than two pills simultaneously increases side effects (nausea/vomiting) without ensuring contraceptive efficacy if the placebo gap is maintained. * **Option C:** Starting a new pack immediately (discarding the current pack entirely) is unnecessary and wasteful; the remaining active pills in the current pack still provide hormonal support. **Clinical Pearls for NEET-PG:** * **The "7-Day Rule":** If 3 or more pills are missed, backup contraception (e.g., condoms) is required for the next **7 days** of continuous pill-taking. * **Emergency Contraception (EC):** If pills were missed in the **first week** and unprotected intercourse occurred, EC should be considered. * **Definition of "Missed":** A pill is technically "missed" if it is delayed by **>24 hours** (for COCs) or **>3 hours** (for traditional Progesterone-Only Pills). * **Most Critical Time:** The most "dangerous" pills to miss are at the **beginning or end** of a cycle, as they extend the hormone-free interval.

Question 165: Which of the following drugs cannot be used for Medical Termination of Pregnancy (MTP) in a patient with bronchial asthma?

A. Prostaglandin (Correct Answer)
B. Oxytocin
C. Mifepristone
D. Ethacrydine

Explanation: ### Explanation **Correct Option: A. Prostaglandin** Prostaglandins, specifically **Prostaglandin F2-alpha (PGF2α)** and its analogues (like Carboprost), are potent **bronchoconstrictors**. In patients with bronchial asthma, these drugs can trigger severe bronchospasm and life-threatening asthma attacks. While Misoprostol (PGE1) is more commonly used for MTP and has a weaker effect on the bronchi, the entire class of prostaglandins is generally avoided or used with extreme caution in asthmatics if safer alternatives exist. **Analysis of Incorrect Options:** * **B. Oxytocin:** This is a posterior pituitary hormone used for induction of labor and preventing PPH. It acts specifically on uterine smooth muscle and has no significant effect on bronchial smooth muscle, making it safe for asthmatics. * **C. Mifepristone:** This is an anti-progestational steroid. It works by blocking progesterone receptors to cause decidual breakdown and cervical softening. It does not interact with the respiratory system and is the first-line drug for medical MTP. * **D. Ethacrydine:** This is an abortifacient used for second-trimester MTP via extra-amniotic instillation. It acts as a local irritant to induce contractions and does not cause bronchoconstriction. **Clinical Pearls for NEET-PG:** * **Carboprost (PGF2α):** Specifically contraindicated in **Asthma**. * **Methylergometrine (Methergine):** Specifically contraindicated in **Hypertension** and Preeclampsia (causes vasoconstriction). * **Misoprostol (PGE1):** The most common prostaglandin used in MTP; it is safer than PGF2α but still used cautiously in severe asthmatics. * **MTP Act Update:** Medical MTP is highly effective up to **9 weeks (63 days)** of gestation using a combination of Mifepristone (200mg) and Misoprostol (800mcg).

Question 166: Which of the following statements about Mirena is false?

A. A progestogen-containing IUCD
B. Contains desogestrel (Correct Answer)
C. Used in hormone replacement therapy
D. Decreases menstrual blood flow

Explanation: **Explanation:** The correct answer is **B (Contains desogestrel)** because Mirena is a Levonorgestrel-releasing Intrauterine System (LNG-IUS). It contains **52 mg of Levonorgestrel**, which is a second-generation synthetic progestogen, not desogestrel (a third-generation progestogen commonly found in oral contraceptive pills). **Analysis of Options:** * **Option A (Progestogen-containing IUCD):** This is true. Mirena belongs to the category of medicated intrauterine devices that release a steady dose of progestogen (20 µg of LNG per 24 hours initially) directly into the uterine cavity. * **Option C (Used in HRT):** This is true. Mirena is FDA-approved for the progestogenic protection of the endometrium during estrogen replacement therapy in menopausal women to prevent endometrial hyperplasia. * **Option D (Decreases menstrual blood flow):** This is true. The local release of LNG causes profound endometrial atrophy. It is a first-line medical management for Heavy Menstrual Bleeding (HMB) and can lead to amenorrhea in approximately 20-40% of users after one year. **High-Yield Clinical Pearls for NEET-PG:** * **Mechanism of Action:** Primarily thickens cervical mucus (preventing sperm penetration) and causes endometrial atrophy (preventing implantation). It does not consistently inhibit ovulation. * **Lifespan:** Currently approved for up to **8 years** for contraception (recently updated from 5 years). * **Non-contraceptive benefits:** Used in the management of endometriosis, adenomyosis, and endometrial hyperplasia without atypia. * **Pearl:** Mirena is the most effective reversible method of contraception, with a Pearl Index (0.1–0.2) comparable to surgical sterilization.

Question 167: What are the contraindications for the use of an intrauterine contraceptive device (IUCD)?

A. Undiagnosed vaginal bleeding and PID
B. Undiagnosed vaginal bleeding
C. Undiagnosed vaginal bleeding and obesity
D. Undiagnosed vaginal bleeding and PID (Correct Answer)

Explanation: **Explanation:** The selection of an Intrauterine Contraceptive Device (IUCD) requires careful screening for contraindications to prevent complications like infection or delayed diagnosis of malignancy. **Why Option D is Correct:** According to the WHO Medical Eligibility Criteria (MEC), **Pelvic Inflammatory Disease (PID)** and **Undiagnosed Vaginal Bleeding** are Category 4 contraindications (unacceptable health risk). 1. **PID:** Inserting an IUCD during an active infection can exacerbate the condition and lead to pelvic sepsis or tubal damage. 2. **Undiagnosed Vaginal Bleeding:** This is a contraindication because the bleeding could be a symptom of an underlying malignancy (like endometrial or cervical cancer) or pregnancy. An IUCD must not be inserted until the cause is diagnosed and serious pathology is ruled out. **Analysis of Incorrect Options:** * **Options A & B:** While they mention undiagnosed bleeding and PID, Option D is the most complete representation of the standard contraindications listed in the question context. * **Option C:** **Obesity** is not a contraindication for IUCD use. In fact, LARC (Long-Acting Reversible Contraception) like the IUCD or LNG-IUS is often preferred for obese patients as it avoids the metabolic risks associated with combined oral contraceptives. **High-Yield Clinical Pearls for NEET-PG:** * **Absolute Contraindications (MEC 4):** Pregnancy, active PID, undiagnosed vaginal bleeding, distorted uterine cavity (large fibroids), and current copper allergy (for Cu-T). * **Wilson’s Disease:** A specific contraindication for Copper-T, but not for the Levonorgestrel-releasing system (Mirena). * **Timing:** The best time for insertion is during menstruation or within 10 days of the cycle to ensure the patient is not pregnant and the cervix is slightly dilated. * **Ideal Candidate:** A parous woman in a stable monogamous relationship (low risk of STIs/PID).

Question 168: What is the best contraceptive method for a young, unmarried female?

A. Oral pills (Correct Answer)
B. Intrauterine contraceptive device (IUCD)
C. Diaphragm
D. Vaginal pessary

Explanation: **Explanation:** The choice of contraceptive for a young, unmarried female is guided by efficacy, ease of use, and the specific clinical profile of the patient. **1. Why Oral Pills are the Correct Answer:** Combined Oral Contraceptive Pills (COCPs) are considered the best choice for this demographic because they are highly effective, reversible, and do not require a clinical procedure for initiation. Beyond contraception, they offer significant **non-contraceptive benefits** that are highly relevant to young women, such as regulation of menstrual cycles, reduction in dysmenorrhea (menstrual pain), and management of acne or hirsutism. **2. Why Other Options are Incorrect:** * **IUCD:** While highly effective (LARC), IUCDs are generally not the first choice for young, unmarried (often nulliparous) women due to a higher risk of expulsion, technical difficulty in insertion due to a tight internal os, and the potential risk of Pelvic Inflammatory Disease (PID) if the patient has multiple sexual partners. * **Diaphragm:** This is a barrier method with a higher failure rate (user-dependent). It requires fitting by a professional and must be inserted before every act of intercourse, making it less convenient for young users. * **Vaginal Pessary:** These are primarily used for pelvic organ prolapse, not contraception. Spermicidal pessaries exist but have very high failure rates and are never recommended as a primary standalone method. **3. NEET-PG High-Yield Pearls:** * **Ideal Contraceptive for Newly Married:** Oral Pills (Centchroman/Saheli is also a popular Indian context answer). * **Ideal Contraceptive for Lactating Mothers:** Progesterone Only Pills (POPs) or Cu-T (after 6 weeks). * **Mechanism of COCPs:** Primarily prevents ovulation by suppressing LH surge. * **Contraindication:** COCPs are contraindicated in smokers >35 years and women with a history of thromboembolism.

Question 169: Oral contraceptives prevent pregnancy by which mechanism?

A. Inhibition of ovulation by inhibiting the release of LH (Correct Answer)
B. Preventing the nidation of the fertilized ovum
C. Increasing the motility of the cilia in the tube and uterus
D. Alteration of the pH of the endometrium

Explanation: **Explanation:** The primary mechanism of action of Combined Oral Contraceptive Pills (COCPs) is the **inhibition of ovulation**. This is achieved through a negative feedback loop on the hypothalamic-pituitary-ovarian axis. 1. **Progestogen component:** Primarily suppresses the secretion of **Luteinizing Hormone (LH)**, thereby preventing the LH surge which is essential for ovulation. 2. **Estrogen component:** Primarily suppresses **Follicle Stimulating Hormone (FSH)**, preventing the development of a dominant follicle. **Analysis of Incorrect Options:** * **B & D:** While COCPs do cause histological changes in the endometrium (making it thin and out-of-phase), which is unfavorable for **nidation** (implantation), this is a secondary/back-up mechanism. Alteration of pH is not a recognized primary mechanism for OCPs. * **C:** This is incorrect; progestogens actually **decrease** the motility of the cilia in the fallopian tubes, which slows down ovum transport. **High-Yield Clinical Pearls for NEET-PG:** * **Primary Mechanism:** Inhibition of ovulation (via LH suppression). * **Secondary Mechanisms:** * Thickening of cervical mucus (hostile to sperm) – *This is the most important mechanism for Progesterone-Only Pills (POPs).* * Endometrial atrophy (prevents implantation). * **Failure Rate:** The Pearl Index for COCPs with perfect use is **0.1 per 100 woman-years**. * **Non-contraceptive benefits:** Reduced risk of ovarian and endometrial cancers (protective effect persists for years after discontinuation).

Question 170: Which contraceptive intrauterine device (IUD) is associated with the highest pregnancy rate?

A. Lippes loop IUD (Correct Answer)
B. Copper T IUD
C. Progestasert IUD
D. Levonorgestrel-releasing IUD (LNG-IUD)

Explanation: **Explanation:** The efficacy of an Intrauterine Device (IUD) is primarily determined by its generation and the presence of bioactive substances (copper or hormones). **1. Why Lippes Loop is the correct answer:** The **Lippes Loop** is a **first-generation, non-medicated (inert)** IUD made of polyethylene. Because it lacks bioactive components like copper or progestogens, its contraceptive action relies solely on a local foreign body inflammatory response in the endometrium. This mechanism is less effective than newer models, resulting in a higher failure rate (Pregnancy rate: **~3 per 100 woman-years**). **2. Analysis of Incorrect Options:** * **Copper T IUD (Second Generation):** These medicated IUDs release copper ions which are toxic to sperm (spermicidal) and inhibit fertilization. They have significantly lower failure rates (e.g., CuT 380A has a pregnancy rate of **<1 per 100 woman-years**). * **Progestasert (Third Generation):** This is a hormone-releasing IUD that releases progesterone. While it has a lower failure rate than the Lippes Loop (~1.3–2.0%), it is less effective than the LNG-IUD and requires yearly replacement. * **LNG-IUD (Mirena):** This is the most effective reversible contraceptive method. It thickens cervical mucus and suppresses the endometrium, with a failure rate of approximately **0.2 per 100 woman-years**, comparable to tubal sterilization. **Clinical Pearls for NEET-PG:** * **Highest Failure Rate:** Lippes Loop (Inert IUD). * **Lowest Failure Rate:** LNG-IUD (Mirena). * **Most Common Side Effect of IUDs:** Bleeding (especially with Copper IUDs). * **Most Common Reason for Removal:** Bleeding and Pain. * **Ideal Candidate for IUD:** A multiparous woman in a stable monogamous relationship.
