Contraception and Family Planning — MCQs

Contraception and Family Planning Indian Medical PG Practice Questions and MCQs

Question 441: Which one of the following is the most suitable situation for prescribing the progestin-only pill for the purpose of contraception?

A. Perimenopausal patients
B. Active liver disease
C. Lactational mother (Correct Answer)
D. Diabetes

Explanation: **Explanation:** The **Progestin-Only Pill (POP)**, also known as the "mini-pill," is the contraceptive of choice for **lactating mothers** (Option C). Unlike Combined Oral Contraceptives (COCs), POPs do not contain estrogen. Estrogen is known to suppress prolactin, thereby decreasing the quantity and quality of breast milk. Progestins, however, have no adverse effect on lactation and are safe for the infant, making them ideal for use starting 6 weeks postpartum. **Analysis of Incorrect Options:** * **Active Liver Disease (Option B):** This is a **strict contraindication** for almost all hormonal contraceptives, including POPs. Steroid hormones are metabolized in the liver; impaired hepatic function can lead to hormone accumulation and further liver stress. * **Perimenopausal Patients (Option A):** While POPs can be used, they are often not the "most suitable" due to the high incidence of irregular spotting and breakthrough bleeding—side effects that can mask endometrial pathology (like hyperplasia or malignancy) common in this age group. * **Diabetes (Option D):** While POPs are generally safe in diabetics without vascular complications, they are not specifically "indicated" for them over other methods. In fact, certain progestins can slightly affect carbohydrate metabolism. **High-Yield NEET-PG Pearls:** * **Mechanism of Action:** POPs primarily work by thickening cervical mucus (preventing sperm penetration) and making the endometrium atrophic. They do not consistently inhibit ovulation (unlike COCs). * **The "3-Hour Rule":** POPs must be taken at the same time every day. A delay of more than 3 hours is considered a "missed pill." * **Ideal Candidate:** Women with contraindications to estrogen (e.g., breastfeeding, smokers >35 years, history of DVT, or migraine with aura).

Question 442: A couple is advised to use barrier methods after vasectomy until which condition is met?

A. 3 months
B. No sperms are detected in the ejaculate (Correct Answer)
C. The next 15 ejaculations
D. None of the above

Explanation: **Explanation:** The correct answer is **B. No sperms are detected in the ejaculate.** **Medical Rationale:** Vasectomy is a permanent sterilization procedure that involves the occlusion or transection of the vas deferens. However, it does **not** result in immediate sterility. Viable spermatozoa remain stored in the distal portion of the reproductive tract (seminal vesicles and ampulla) beyond the site of the incision. These "stored" sperms can cause pregnancy if unprotected intercourse occurs shortly after the procedure. Therefore, a couple must use an alternative barrier method until **Azoospermia** (zero sperm count) is confirmed by a semen analysis. **Analysis of Options:** * **Option A (3 months):** While 3 months is the standard *timeframe* recommended before performing the first follow-up semen analysis, it is not the definitive clinical endpoint. Sterility is confirmed by the lab result, not the calendar. * **Option C (15 ejaculations):** Historically, 15–20 ejaculations were thought to clear the tract. However, recent guidelines emphasize that the number of ejaculations is less reliable than the laboratory confirmation of azoospermia. * **Option D:** Incorrect, as Option B is the gold-standard clinical requirement. **High-Yield Clinical Pearls for NEET-PG:** * **Confirmation:** The first semen analysis is typically done **12 weeks (3 months)** post-procedure. * **Criteria for Success:** Ideally, two consecutive semen analyses showing azoospermia are preferred, though one sample showing no motile sperm is often accepted clinically. * **Failure Rate:** Vasectomy has a failure rate of approximately **0.1% to 0.15%** (more effective than tubal ligation). * **Complications:** The most common late complication is **Sperm Granuloma**; the most common early complications are hematoma and infection. * **Reversibility:** Vasovasostomy can reverse the procedure, but success rates decrease over time due to the development of anti-sperm antibodies.

Question 443: Which is the ideal contraceptive for a couple who have infrequent coital frequency due to professional commitments?

A. Barrier method (Correct Answer)
B. Intrauterine contraceptive device (IUCD)
C. Oral contraceptive pill (OCP)
D. Depot medroxyprogesterone acetate (DMPA)

Explanation: **Explanation:** The choice of contraceptive method depends heavily on the patient's lifestyle, frequency of intercourse, and future fertility goals. **Why Barrier Methods are Ideal:** For couples with **infrequent coital frequency**, the **Barrier method (Condoms)** is the most suitable choice. Unlike hormonal or long-acting methods, barrier methods are **"coitus-dependent."** They are used only when required, avoiding unnecessary systemic exposure to hormones or invasive procedures. Additionally, they provide the added benefit of protection against Sexually Transmitted Infections (STIs), which is a high-yield consideration in family planning. **Analysis of Incorrect Options:** * **IUCD (Option B):** These are Long-Acting Reversible Contraceptives (LARC). They are ideal for couples seeking long-term spacing (3–10 years) with frequent intercourse, as they provide continuous protection regardless of coital frequency. * **OCP (Option C):** Oral pills require strict daily compliance to maintain efficacy. For a couple with infrequent contact, taking a daily systemic hormone is considered unnecessary "over-treatment." * **DMPA (Option D):** This injectable contraceptive is administered every 3 months. It is generally reserved for women who desire long-term contraception but struggle with daily pill compliance. It can cause a significant delay in the return of fertility (up to 7–9 months), making it less ideal for couples who may want to conceive soon. **NEET-PG High-Yield Pearls:** * **Ideal for newly married:** OCPs (Centchroman/Saheli is often preferred in the Indian context as a non-steroidal once-a-week pill). * **Ideal for lactating mothers:** Progestogen-only pills (POPs) or IUCD (after 6 weeks). * **Ideal for emergency contraception:** Levonorgestrel (1.5mg) within 72 hours or Copper-T (most effective) within 5 days. * **Pearl:** Always screen for "Medical Eligibility Criteria" (WHO MEC) before prescribing any hormonal method.

Question 444: What is the dose of ulipristal acetate when used for emergency contraception?

A. 300 mg
B. 30 mg (Correct Answer)
C. 300 µg
D. 30 µg

Explanation: **Explanation:** Ulipristal acetate (UPA) is a selective progesterone receptor modulator (SPRM) and is currently considered the most effective oral emergency contraceptive (EC). **1. Why 30 mg is correct:** The standard dose for emergency contraception is a **single 30 mg tablet** taken orally. Its primary mechanism of action is the inhibition or delay of ovulation. Unlike Levonorgestrel (LNG), which is only effective before the LH surge begins, Ulipristal can delay ovulation even after the LH surge has started (but before it peaks), making it effective for up to **120 hours (5 days)** after unprotected intercourse. **2. Why other options are incorrect:** * **300 mg (Option A):** This is a massive overdose for EC. Higher doses of UPA (e.g., 5-10 mg daily) are used for the medical management of uterine fibroids, but 300 mg is not a standard clinical dose. * **300 µg and 30 µg (Options C & D):** These doses are far too low to inhibit ovulation. For comparison, the "Minipill" (Progestogen-only pill) typically contains doses in the microgram range (e.g., Levonorgestrel 30 µg), but emergency contraception requires a much higher "stat" dose to be effective. **High-Yield Clinical Pearls for NEET-PG:** * **Window of Efficacy:** Ulipristal is effective up to 120 hours (5 days), whereas LNG is ideally taken within 72 hours. * **Efficacy in Obesity:** Ulipristal is more effective than LNG in women with a BMI >30 kg/m². * **Breastfeeding Caution:** Women should avoid breastfeeding for **one week** after taking Ulipristal (express and discard milk), unlike LNG which is safe during lactation. * **Drug Interaction:** Do not start hormonal contraception (like OCPs) for at least 5 days after taking UPA, as they may interfere with each other's efficacy.

Question 445: Which natural family planning method is based on the Ogino-Knauss theory?

A. Basal Body Temperature (BBT) method
B. Rhythm method (Correct Answer)
C. Lactational amenorrhea
D. Withdrawal method

Explanation: **Explanation:** The **Rhythm method** (also known as the Calendar method) is based on the **Ogino-Knauss theory**, which calculates the fertile window based on the length of previous menstrual cycles. **1. Why the Rhythm Method is correct:** The theory relies on three physiological assumptions: * **Ovulation** occurs 14 days (± 2 days) before the onset of the next menses. * **Spermatozoa** can survive in the female reproductive tract for up to 48–72 hours. * The **Ovum** survives for approximately 12–24 hours after release. By subtracting 18 days from the shortest cycle (to find the first fertile day) and 11 days from the longest cycle (to find the last fertile day), a woman can estimate her "unsafe" period. **2. Why other options are incorrect:** * **Basal Body Temperature (BBT):** Relies on the thermogenic effect of **Progesterone**, which causes a rise in body temperature (0.5–1°F) *after* ovulation has occurred. * **Lactational Amenorrhea (LAM):** Based on the physiological suppression of GnRH, LH, and FSH due to high **Prolactin** levels during exclusive breastfeeding. * **Withdrawal method (Coitus Interruptus):** A behavioral method involving the removal of the penis from the vagina before ejaculation; it is not based on cyclical timing or the Ogino-Knauss theory. **Clinical Pearls for NEET-PG:** * **Pearl 1:** The Rhythm method is the **least reliable** natural method due to cycle variability (Failure rate: ~25%). * **Pearl 2:** The **Billings method** (Cervical Mucus method) identifies the fertile period by observing "Spinnbarkeit" (thin, stretchy, egg-white mucus) caused by high estrogen. * **Pearl 3:** The **Symptothermal method** is the most effective natural method as it combines BBT, cervical mucus changes, and calendar calculations.

Question 446: All the following are contraindications for copper-containing IUCDs except?

A. Wilson's disease
B. Pregnancy
C. Undiagnosed genital bleeding
D. Ischemic heart disease (Correct Answer)

Explanation: **Explanation:** The correct answer is **Ischemic Heart Disease (IHD)**. According to the WHO Medical Eligibility Criteria (MEC), IHD is classified as **Category 1** for Copper IUCDs (Cu-IUD), meaning there is no restriction for its use. Unlike hormonal contraceptives (like OCPs), Cu-IUDs do not contain estrogen or progestogens, which are associated with thromboembolic risks and adverse lipid profiles. Therefore, they are safe for women with cardiovascular conditions. **Analysis of Contraindications:** * **Wilson’s Disease (Option A):** This is a specific contraindication for **Copper-containing** IUCDs because the device can potentially interfere with copper metabolism or exacerbate the systemic copper burden in these patients. (Note: LNG-IUS is an alternative here). * **Pregnancy (Option B):** This is an absolute contraindication (MEC Category 4). Insertion during pregnancy can lead to septic abortion, pelvic infection, or preterm labor. * **Undiagnosed Genital Bleeding (Option C):** This is a Category 4 contraindication. Insertion must be delayed until a serious underlying pathology (like endometrial or cervical malignancy) is ruled out, as the IUCD may worsen bleeding or complicate the diagnosis. **High-Yield Clinical Pearls for NEET-PG:** * **MEC Category 4 (Absolute Contraindications):** Current PID, unexplained vaginal bleeding, copper allergy (for Cu-IUD), and gestational trophoblastic disease with high hCG levels. * **Ideal Candidate:** A parous woman in a stable monogamous relationship with no history of PID. * **Most Common Side Effect:** Increased menstrual blood loss (menorrhagia) and dysmenorrhea. * **Most Common Reason for Removal:** Excessive menstrual bleeding. * **Post-exposure Prophylaxis:** Cu-IUD is the most effective emergency contraceptive if inserted within 5 days of unprotected intercourse.

Question 447: The failure rate of oral contraceptive pills (OCPs) is lowest in which of the following groups?

A. Nullipara (Correct Answer)
B. Multipara
C. Grand multipara
D. Same in all groups

Explanation: The failure rate of oral contraceptive pills (OCPs) is primarily influenced by **compliance and user consistency**. In clinical studies and epidemiological data, parity (the number of times a woman has given birth) has been shown to correlate with the efficacy of hormonal contraception. ### **Explanation of the Correct Answer** **A. Nullipara:** Nulliparous women (those who have never given birth) generally exhibit the lowest failure rates for OCPs. This is attributed to higher motivation levels and stricter adherence to the daily dosing schedule. Furthermore, physiological factors such as lower body mass index (on average) compared to multiparous women and a lack of "child-rearing distractions" contribute to better compliance and more consistent drug serum levels, leading to maximum contraceptive efficacy. ### **Explanation of Incorrect Options** * **B & C. Multipara and Grand Multipara:** As parity increases, the failure rate of OCPs tends to rise. This is often due to "user failure" rather than "method failure." Women with multiple children often face busier daily routines, leading to missed pills. Additionally, physiological changes (such as increased weight or metabolic changes post-pregnancy) can theoretically influence drug pharmacokinetics, though behavioral factors remain the primary cause of failure. * **D. Same in all groups:** This is incorrect because real-world "typical use" failure rates vary significantly across different demographics, including age and parity. ### **NEET-PG High-Yield Pearls** * **Pearl Index for OCPs:** The theoretical (perfect use) failure rate is **0.3 per 100 woman-years**, while the typical use failure rate is approximately **8-9 per 100 woman-years**. * **Most Common Cause of Failure:** Missing a pill (User failure). * **Drug Interactions:** OCP efficacy is reduced by **Enzyme Inducers** (e.g., Rifampicin, Phenytoin, Carbamazepine). * **Contraindication:** OCPs are contraindicated in smokers >35 years and women with a history of Thromboembolism.

Question 448: With contraceptive failure, which method has a relatively increased risk of ectopic pregnancy?

A. Condoms
B. Vasectomy
C. Tubal sterilization (Correct Answer)
D. Vaginal ring

Explanation: **Explanation:** The core concept behind this question is the distinction between **absolute risk** and **relative risk**. While all contraceptives significantly reduce the absolute risk of any pregnancy (including ectopic), if a pregnancy *does* occur despite the method, the likelihood of it being ectopic varies. **1. Why Tubal Sterilization is Correct:** Tubal sterilization is highly effective. However, if it fails, it is often due to **recanalization** or the formation of a **tuboperitoneal fistula**. These structural changes can impede the normal passage of a fertilized ovum through the fallopian tube while still allowing sperm to pass, leading to an embryo implanting in the tube. Statistically, if a woman becomes pregnant after tubal ligation, there is a **~30% relative risk** that the pregnancy will be ectopic. **2. Why the Other Options are Incorrect:** * **Condoms and Vaginal Rings:** These are temporary methods. If they fail (due to breakage or inconsistent use), fertilization usually occurs in a physiologically normal environment, meaning the pregnancy is most likely to implant normally in the uterus. * **Vasectomy:** Failure usually results from unprotected intercourse before the semen is cleared of sperm. Since the female reproductive anatomy remains unaltered, there is no increased relative risk for ectopic implantation. **Clinical Pearls for NEET-PG:** * **Highest Relative Risk:** Among all contraceptive failures, the **Progestin-only Pill (POP)** and **Levonorgestrel-IUD (LNG-IUD)** also carry a high relative risk of ectopic pregnancy because they primarily affect tubal motility or cervical mucus rather than completely suppressing ovulation. * **Absolute vs. Relative:** The *absolute* risk of ectopic pregnancy is lowest in women using effective contraception compared to those using no contraception. * **CREST Study Fact:** The risk of ectopic pregnancy after sterilization is higher in younger women and highest with the use of **bipolar cautery** compared to clips or rings.

Question 449: What is the maximum amount of progesterone (in micrograms) contained in a low-dose oral contraceptive pill?

A. 15
B. 25
C. 35 (Correct Answer)
D. 45

Explanation: **Explanation:** The term **"Low-dose Oral Contraceptive Pill" (OCP)** specifically refers to the concentration of the estrogen component (Ethinyl Estradiol), not the progesterone. However, the classification of these pills is strictly defined by pharmacological standards to minimize metabolic side effects while maintaining contraceptive efficacy. 1. **Why 35 µg is correct:** In modern clinical practice, a "low-dose" OCP is defined as a pill containing **less than 50 µg** of Ethinyl Estradiol. Most standard low-dose formulations available (such as Mala-N or Mala-D) contain exactly **30 µg to 35 µg** of estrogen. Therefore, 35 µg represents the upper limit of what is classified as a standard low-dose pill. 2. **Why other options are incorrect:** * **15 µg & 25 µg:** These are considered "ultra-low-dose" pills. While they have fewer estrogenic side effects, they are associated with higher rates of breakthrough bleeding and a narrower margin for error if a dose is missed. * **45 µg:** This falls just below the 50 µg threshold but is not a standard manufactured dose for low-dose categorization in competitive exams; 35 µg is the classic textbook benchmark. **High-Yield Clinical Pearls for NEET-PG:** * **Generation Gap:** First-generation pills contained >50 µg of estrogen. Modern "Low-dose" pills (2nd/3rd Gen) contain 30–35 µg. * **Mechanism:** The estrogen component primarily inhibits **FSH** (preventing follicular selection), while the progestogen inhibits **LH** (preventing ovulation) and thickens cervical mucus. * **Mala-N vs. Mala-D:** Both contain 0.03 mg (30 µg) Ethinyl Estradiol and 0.15 mg Levonorgestrel. Mala-N is free (Government supply), while Mala-D is subsidized. * **Centchroman (Saheli):** A high-yield non-steroidal alternative; it is a SERM taken twice weekly for 3 months, then once weekly.

Question 450: Which of the following is NOT used as emergency contraception?

A. Saheli (Correct Answer)
B. Combined oral contraceptive pills
C. Intrauterine device (IUD)
D. High-dose estrogen for 5 days

Explanation: **Explanation:** The correct answer is **Saheli (Centchroman)**. **1. Why Saheli is the correct answer:** Saheli is a **Selective Estrogen Receptor Modulator (SERM)**. It is used as a **non-steroidal, weekly oral contraceptive pill** for routine birth control, not for emergency use. Its mechanism involves altering the uterine endometrium to prevent implantation and speeding up ovum transport. Because it requires a steady-state buildup (taken twice weekly for the first 3 months, then once weekly), it is ineffective as a post-coital emergency measure. **2. Why the other options are incorrect (Emergency Contraceptive Methods):** * **Combined Oral Contraceptive Pills (COCs):** Used in the **Yuzpe Regimen**. It involves taking two doses (each containing 100 mcg Ethinyl Estradiol + 0.5 mg Levonorgestrel) 12 hours apart within 72 hours of intercourse. * **Intrauterine Device (IUD):** The **Copper T-380A** is the **most effective** emergency contraceptive. It can be inserted up to 5 days (120 hours) after unprotected intercourse and prevents pregnancy by interfering with fertilization and implantation. * **High-dose Estrogen:** Historically used (e.g., Ethinyl Estradiol 5mg daily for 5 days), this method is now largely obsolete due to severe side effects like nausea and vomiting, but it remains a recognized pharmacological method for emergency contraception. **High-Yield Clinical Pearls for NEET-PG:** * **Drug of Choice (DOC):** Levonorgestrel (LNG) 1.5 mg single dose (within 72 hours) is the current standard. * **Most Effective Method:** Copper IUD (failure rate <0.1%). * **Ulipristal Acetate:** A Selective Progesterone Receptor Modulator (SPRM) effective up to 120 hours (5 days); it is more effective than LNG in obese women. * **Mifepristone:** Can be used as an emergency contraceptive in low doses (10–25 mg).
