title: [The intrauterine system with progesterone and synthetic progestational hormones].
abstract: Release of progesterone in the endouterine system modifies the cervical mucus and blocks proliferation of the endometrium. The mode of action is therefore hemostatic, antalgic and contraceptive. Results are excellent in these three, often combined indications.
