Which of the following contraceptives could be effective in avoiding pregnancy if used within 72 hours after casual unprotected intercourse?
- Androgen - FSH combination
- Testosterone - Relaxin combination
- Relaxin - Oxytocin combination
- Progestogen - Estrogen combination
The Correct Option is D
Approach Solution - 1
Emergency Contraception Mechanism: Emergency contraceptive pills (ECPs) typically contain: - High-dose progestogen (levonorgestrel) alone OR - Combined progestogen-estrogen (Yuzpe method)
These work by: 1. Delaying or inhibiting ovulation 2. Preventing fertilization 3. Possibly interfering with implantation
Thus, the correct answer is (D) Progestogen-Estrogen combination, representing the hormonal composition of emergency contraceptive pills.
Approach Solution -2
Emergency contraceptive pills (morning-after pills) contain high doses of these hormones.
They work by:
- Delaying ovulation
- Altering the endometrium to prevent implantation.
- Must be taken within 72 hours of unprotected intercourse.
The correct option is (D) Progestogen-Estrogen combination.
