Mechanism of action

The Mona Lisa NT Cu380 Mini is a non-hormonal intrauterine contraceptive device that works through copper-mediated mechanisms. The copper ions released from the device surface inhibit sperm motility and viability, and alter the endometrial environment to prevent fertilization and implantation. This mechanical and chemical approach provides long-acting reversible contraception without systemic hormonal effects.
