Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Students often harbor the misconception that ALL oral contraceptive pills inhibit ovulation.
This question tests the ability to differentiate between the systemic HPO-axis suppression of steroidal COCs and the localized, anti-implantation (uterine) effect of the non-steroidal pill Saheli, which allows normal ovarian cyclicity.
