Operating principle

Metal (silver / gold) and plasticSpirals inhibit the vital activity of spermatozoa, making it impossible to fertilize the egg, change the physiological transformation of the endometrium, which prevents the implantation of a fertilized egg. The IUD encourages contractions of the uterus and fallopian tubes, due to which the fertilized egg gets prematurely into the uterus: the endometrium is not ready to receive the egg, the trophoblast is defective, so implantation becomes impossible. Against the background of hormones containing IUD, the viscosity of the cervical secretion increases, as a result of which the migration of spermatozoa through the fallopian tubes and uterus decreases, ovulation is suppressed.
