Ethical Aspects of Contraception and Sterilization Indian Medical PG Practice Questions and MCQs
Question 1: A GSP4 woman comes for routine sonography for the first time. She has four daughters and expresses a desire for a boy this time, asking for sex determination. To abide by ethical guidelines, what should you do?
- A. Check routine ANC and sex for developmental abnormalities and do not reveal gender to the patient (Correct Answer)
- B. Check routine ANC and sex for developmental abnormalities and do reveal gender to the patient
- C. Do reveal gender if a girl
- D. Check only routine ANC, do not check sex
Explanation: ***Check routine ANC and sex for developmental abnormalities and do not reveal gender to the patient*** - It is **illegal** and **unethical** to reveal the sex of the fetus in many countries, including India, to prevent **sex-selective abortions**. - The primary purpose of a routine antenatal ultrasound is to assess fetal **health** and **developmental abnormalities**, not to determine sex for parental preference. *Check routine ANC and sex for developmental abnormalities and do reveal gender to the patient* - Revealing the gender to the patient directly facilitates **sex-selective abortion**, which is medically unethical and illegal due to the potential for harm to the fetus and society. - This practice would violate the **Pre-Conception and Pre-Natal Diagnostic Techniques (PCPNDT) Act** in India, which prohibits gender determination. *Do reveal gender if a girl* - Revealing the gender, regardless of whether it is a boy or a girl, can lead to **gender-biased selective abortions**, particularly in cultures with a strong preference for male offspring. - This action undermines the ethical principles of **non-maleficence** and **justice** by potentially facilitating harm based on gender preference. *Check only routine ANC, do not check sex* - While the primary focus is routine antenatal care, avoiding the assessment of fetal sex entirely could lead to **missing potential developmental abnormalities** that might be identifiable through observation of external genitalia. - A thorough ultrasound examination routinely includes a visual check of fetal anatomy, which can incidentally reveal gender, but this information should not be shared with the parents for selection purposes.
Question 2: What are the established thresholds for permanent sterility in women for prepubertal and premenopausal exposure to radiation?
- A. 20 Gy and 6 Gy, respectively (Correct Answer)
- B. 6 Gy and 2 Gy, respectively
- C. 0.5 to 2 Gy and 20 Gy, respectively
- D. 1 Gy and 0.2 Gy, respectively
Explanation: ***20 Gy and 6 Gy, respectively*** - The threshold for **permanent sterility** in prepubertal girls is approximately **20 Gy** or higher due to their larger follicular reserve and greater radioresistance of immature ovaries. - The threshold for **permanent sterility** in premenopausal women is significantly lower, around **6 Gy** (range 6-12 Gy, age-dependent), as their ovaries have fewer follicles and are more radiosensitive. - These thresholds represent single-dose or fractionated-equivalent exposures that result in complete and irreversible loss of ovarian function. *12 Gy and 2 Gy, respectively* - **12 Gy** is below the threshold for permanent sterility in prepubertal girls; it may cause temporary ovarian damage but usually not permanent sterility. - **2 Gy** typically causes temporary amenorrhea in premenopausal women but not permanent sterility; permanent damage requires higher doses (≥6 Gy). *0.5 to 2 Gy and 20 Gy, respectively* - The **0.5-2 Gy** range is far too low to cause permanent sterility in prepubertal girls; this range may cause temporary effects in adults. - While **20 Gy** is an appropriate threshold, it is incorrectly assigned to the premenopausal group rather than the prepubertal group; premenopausal women develop permanent sterility at much lower doses (6-12 Gy). *6 Gy and 2 Gy, respectively* - **6 Gy** is the lower threshold for premenopausal women, not prepubertal girls; prepubertal ovaries can tolerate much higher doses (≥20 Gy) before permanent sterility occurs. - **2 Gy** is insufficient to cause permanent sterility in premenopausal women; this dose typically causes only temporary amenorrhea.
Question 3: Which of the following can be considered as grounds of divorce under matrimonial law?
- A. Sterility
- B. Frigidity
- C. Impotence developing after the marriage (Correct Answer)
- D. Temporary Mental illness
Explanation: ***Impotence developing after the marriage*** - **Impotence** (inability to consummate the marriage) can constitute a ground for **nullity** if it existed **at the time of marriage** and was not disclosed. - However, **impotence developing after marriage** may be considered under certain legal frameworks as inability to fulfill marital obligations, though its status varies by jurisdiction. - In the context of medical jurisprudence, **sexual incapacity** affecting the continuation of marriage is recognized as a potential ground in matrimonial disputes. - This is the **most appropriate answer** among the given options as it relates to inability to fulfill a fundamental aspect of marriage. *Sterility* - **Sterility** (inability to conceive children) is generally **not considered a ground for divorce** under most matrimonial laws. - It does not prevent consummation of marriage or fulfillment of other marital duties. - While it may cause personal distress, legal systems distinguish between inability to conceive and inability to engage in sexual relations. *Frigidity* - **Frigidity** (lack of sexual desire or responsiveness) is typically **not a sufficient ground for divorce** on its own. - If the spouse is physically capable of consummating the marriage, lack of desire alone does not constitute legal grounds. - It may overlap with other marital issues but has weaker legal standing compared to actual physical incapacity. *Temporary Mental illness* - **Temporary mental illness** is generally **not a ground for divorce** because it implies a recoverable condition. - For mental disorder to constitute grounds for divorce under Indian matrimonial law (Hindu Marriage Act Section 13), it must be: - **Incurable** or of such nature that cohabitation becomes unreasonable - **Continuous or intermittent** mental disorder of sufficient severity - A **temporary** condition that can be cured does not meet these criteria.
Question 4: The MTP Act was introduced in:
- A. 1961
- B. 1971 (Correct Answer)
- C. 1975
- D. 1974
Explanation: ***1971*** - The **Medical Termination of Pregnancy (MTP) Act** was enacted in **1971** in India. - This legislation was a significant step towards legalizing and regulating abortion services in the country under specific conditions. - The Act came into force on **April 1, 1972**. *1961* - This year is not associated with the introduction of the MTP Act. - Other significant legislative changes may have occurred, but not related to medical termination of pregnancy. *1975* - The year **1975** is incorrect as the MTP Act was already in effect from 1971. - This year marked a different period in India's legal and social history. *1974* - The year **1974** is also incorrect; the MTP Act was passed and came into force before this date. - No major amendments to the MTP Act were introduced in 1974.
Question 5: Which of the following is NOT used as an emergency contraceptive?
- A. RU 486
- B. Danazol (Correct Answer)
- C. Copper T
- D. OCpill
Explanation: ***Danazol*** - **Danazol** is an **androgen derivative** primarily used to treat **endometriosis** and **fibrocystic breast disease**, not for emergency contraception. - Its mechanism involves suppressing **ovarian function** and creating an anovulatory state, which is not suitable for immediate post-coital intervention. *RU 486* - **RU 486 (Mifepristone)** is a **progesterone receptor modulator** that can be used as an emergency contraceptive, especially at higher doses. - It acts by **blocking progesterone receptors**, preventing implantation or inducing abortion if pregnancy has already occurred. *Copper T* - The **Copper T (intrauterine device - IUD)** is a highly effective method of emergency contraception if inserted within 5 days of unprotected intercourse. - It works by causing a **spermicidal effect** and preventing fertilization or implantation by inducing an inflammatory reaction in the uterus. *OCpill* - **OCPills (oral contraceptive pills)**, usually a combination of estrogen and progestin, can be used as emergency contraception when taken in higher doses. - This method, known as the **Yuzpe regimen**, involves taking two doses of combined oral contraceptives within 72 hours of unprotected intercourse to inhibit ovulation or fertilization.
Question 6: A 14-year-old victim of sexual assault with 22 weeks gestation has been brought for Medical Termination of Pregnancy (MTP). Which of the following statements is true?
- A. One doctor is involved
- B. MTP done in 2nd trimester only when mother's life is in danger
- C. MTP can be carried out up to 24 weeks (Correct Answer)
- D. MTP cannot be more than 20 weeks
Explanation: ***MTP can be carried out up to 24 weeks*** - The **Medical Termination of Pregnancy (Amendment) Act, 2021**, allows termination of pregnancy up to **24 weeks** for certain vulnerable groups, including survivors of sexual assault and minors. - As a 14-year-old victim of sexual assault, she falls under the category which permits MTP up to 24 weeks. *One doctor is involved* - For pregnancies between 12 and 20 weeks, the opinion of **two registered medical practitioners** is required for MTP. - Beyond 20 weeks up to 24 weeks, as in this case, the opinion of **two registered medical practitioners** is also mandatory. *MTP done in 2nd trimester only when mother's life is in danger* - While danger to the mother's life is a valid reason for MTP, the **MTP Act 2021** has expanded the grounds for MTP in the second trimester (beyond 12 weeks) to include other categories like **sexual assault survivors** and **minors**, even if the mother's life is not immediately in danger. - The primary consideration here is the **vulnerability** of the pregnant person, not solely imminent danger to life. *MTP cannot be more than 20 weeks* - This statement is incorrect as per the **Medical Termination of Pregnancy (Amendment) Act, 2021**. - The Act raised the upper gestation limit from 20 to **24 weeks** for specific categories of women, including victims of sexual assault and minors, aligning with the current case.
Question 7: The mechanism of action of emergency contraception includes the following except:
- A. Degeneration of corpus luteum (Correct Answer)
- B. Prevention of implantation of fertilized egg.
- C. Inhibition of fertilization
- D. By preventing or delaying ovulation
Explanation: ***Degeneration of corpus luteum*** - Emergency contraception primarily works by interfering with ovulation and fertilization. It does **not directly cause degeneration of the corpus luteum**. - The **corpus luteum** forms after ovulation, and its degradation is a natural process (luteolysis) if pregnancy does not occur. Emergency contraception acts earlier in the reproductive process and does not target the corpus luteum. - This is the **correct answer** as it is NOT a mechanism of emergency contraception. *By preventing or delaying ovulation* - This is the **primary mechanism** of action for most forms of emergency contraception, particularly those containing **levonorgestrel (LNG)** and **ulipristal acetate (UPA)**. - By delaying the release of an egg from the ovary, it prevents the possibility of fertilization. - This is the most established and clinically significant mechanism. *Inhibition of fertilization* - Emergency contraception may affect fertilization by altering **cervical mucus** thickness, making it less penetrable to sperm. - Some evidence suggests effects on **sperm motility** or function, though this mechanism is less well-established than ovulation inhibition. - This represents a possible secondary mechanism. *Prevention of implantation of fertilized egg* - **Current evidence does NOT support this as a mechanism** for levonorgestrel or ulipristal acetate emergency contraception. - Studies by **WHO, ACOG, FIGO, and ICMR** have shown that LNG-EC is ineffective once fertilization has occurred. - The **copper IUD** used for emergency contraception may have some anti-implantation effects due to its inflammatory action on the endometrium. - However, for hormonal EC (the most common form), prevention of implantation is **not an established mechanism** based on current medical evidence.
Question 8: The contraceptive choice for a 38 year old woman with chronic hypertension and history of dysmenorrhea and menorrhagia (malignancy ruled out) is:
- A. Copper intrauterine device
- B. Sterilization
- C. Combined oral contraceptive pills
- D. Levonorgestrel intrauterine device (Correct Answer)
Explanation: ***Levonorgestrel intrauterine device*** - The **Levonorgestrel IUD** is an excellent choice as it provides effective contraception while also treating menorrhagia and dysmenorrhea due to its local progesterone release. - It is safe for women with **hypertension** as it is a **non-estrogen-containing method**, avoiding the increased risk of thrombotic events associated with estrogen. *Copper intrauterine device* - While an effective non-hormonal contraceptive, the **copper IUD** can worsen **dysmenorrhea** and **menorrhagia**, which are existing concerns for the patient. - It does not offer any therapeutic benefits for her heavy and painful periods. *Sterilization* - Although it provides permanent and highly effective contraception, **sterilization** does not address the patient's symptoms of **dysmenorrhea** and **menorrhagia**. - It is an irreversible procedure and typically considered when no further childbearing is desired and symptomatic relief is not a primary concern for the contraceptive method itself. *Combined oral contraceptive pills* - **Combined oral contraceptive pills (COCs)** are generally contraindicated or used with caution in women with uncontrolled **hypertension** due to the estrogen component, which can increase the risk of cardiovascular events, including thrombosis. - While COCs can improve dysmenorrhea and menorrhagia, the cardiovascular risks in a 38-year-old with chronic hypertension outweigh these benefits.
Question 9: What is the most distinctive functional characteristic of the barrier method shown?
- A. Can be retained in vagina for extended periods (Correct Answer)
- B. More effective than male condom
- C. Must be inserted immediately after coitus
- D. Consists of nonoxynol-9 impregnated latex
Explanation: ***Can be retained in vagina for extended periods*** - The image displays a **contraceptive sponge**, which can be inserted up to 24 hours before intercourse and provides continuous protection for that duration, allowing for multiple acts of coitus. - It must be left in place for at least **6 hours after the last intercourse** but not for more than **30 hours in total**. - This extended retention capability is a **distinctive feature** of the contraceptive sponge compared to other barrier methods. *More effective than male condom* - The **contraceptive sponge** has a **higher failure rate** (typical use: 12-24% for parous women, 9-12% for nulliparous women) compared to male condoms (typical use failure rate of 13%). - Male condoms are generally **more effective** in preventing pregnancy and provide additional protection against sexually transmitted infections (STIs). *Must be inserted immediately after coitus* - The contraceptive sponge is designed for **pre-coital insertion**, not post-coital use. - It should be inserted **before intercourse** to be effective, as its mechanism relies on trapping sperm and releasing spermicide continuously. - It remains effective for multiple acts of intercourse within the 24-hour insertion window. *Consists of nonoxynol-9 impregnated polyurethane* - While this statement is **technically accurate** (the contraceptive sponge is made of polyurethane foam impregnated with 1000mg of nonoxynol-9), it describes the **composition** rather than a functional characteristic. - The most **clinically distinctive** feature of the sponge is its extended retention time, making Option A the **best answer** among the choices provided. - This distinguishes the sponge from other barrier methods like diaphragms or cervical caps, which also use spermicide but have different insertion timing requirements.
Question 10: After an initial pregnancy resulted in a spontaneous loss in the first trimester, your patient is concerned about the possibility of this recurring. What is the chance of recurrence?
- A. Depends on the genetic makeup of the prior abortus
- B. Is no different than it was prior to the miscarriage (Correct Answer)
- C. Is increased to approximately 50%
- D. Is increased most likely to greater than 50%
Explanation: ### Explanation **Correct Answer: B. Is no different than it was prior to the miscarriage** **1. Why Option B is Correct:** Spontaneous abortion (miscarriage) is a common event, occurring in approximately 10–15% of clinically recognized pregnancies. The vast majority (up to 50–70%) of isolated first-trimester losses are due to **sporadic chromosomal abnormalities** (e.g., autosomal trisomies), which are random events. Statistically, after a **single** spontaneous loss, the risk of a subsequent miscarriage remains approximately **15–20%**, which is essentially the same as the baseline risk for the general population. The risk only begins to rise significantly after two or more consecutive losses. **2. Why Other Options are Wrong:** * **Option A:** While the genetic makeup of the abortus explains *why* that specific pregnancy failed, it does not dictate the recurrence risk for the next pregnancy unless a parental balanced translocation is present (which is rare and not the default assumption after a single loss). * **Options C & D:** These options overestimate the risk. A 50% recurrence risk is not reached even after three consecutive losses. After two losses, the risk rises to ~25–30%, and after three, it reaches ~33–45%. **3. Clinical Pearls for NEET-PG:** * **Most common cause of first-trimester abortion:** Fetal genetic factors (Chromosomal anomalies). * **Most common specific chromosomal anomaly:** Autosomal Trisomy (Trisomy 16 is the most common specific trisomy). * **Recurrent Pregnancy Loss (RPL):** Defined by the ASRM as **two or more** failed clinical pregnancies. Investigations for RPL are generally not indicated after a single isolated loss. * **Prognosis:** Even after 3 losses, the most likely outcome for the next pregnancy is a live birth (approx. 60–70% success rate without intervention).
