Vedclass · Answer

(B) Injectable contraceptives like $DMPA$ (Depot Medroxyprogesterone Acetate) contain synthetic progestogens. These hormones act by providing negative feedback to the hypothalamus and the anterior pituitary gland. This feedback mechanism inhibits the release of gonadotropins,specifically $FSH$ (Follicle Stimulating Hormone) and $LH$ (Luteinizing Hormone). Since the surge of $LH$ is essential for ovulation,the inhibition of these gonadotropins prevents the process of ovulation,thereby acting as an effective contraceptive.
