Mechanism of action

DMPA acts as a long-acting reversible contraceptive by inhibiting the luteinizing hormone (LH) surge required for ovulation. It also alters the endometrium and increases cervical mucus viscosity, creating multiple barriers to fertilization. The depot formulation provides sustained hormone release over 3 months (intramuscular) or 1 month (subcutaneous), maintaining contraceptive efficacy with minimal dosing frequency.
