AIIMS 2019 Biology Contraceptive Methods MCQ Question

Progestasert is an intrauterine device (IUD) that releases the hormone progesterone, not estrogen, which helps in preventing pregnancy by thickening cervical mucus and inhibiting ovulation. Option A is incorrect because Saheli is a weekly oral contraceptive that contains a non-steroidal compound, not a traditional hormone. Option C is misleading as Cu⁻T (Copper T) is not a barrier method; it is a copper IUD that prevents fertilization through a spermicidal effect. Option D is false since vasectomy and tubectomy are considered permanent methods of contraception, as they involve surgical procedures to block the reproductive pathways.
