Contraceptive action Mikrolyuta progestin caused by peripheral effects. Thus, the drug helps:
- change in the properties of cervical and cervical mucus (it becomes more viscous, which in turn prevents penetration of sperm into the uterus);
- slowing down the process of proliferation of the endometrium (thereby create conditions that prevent implantation of a fertilized egg cell);
- inhibition of the release of hypothalamic releasing factors;
- decreased function of the corpus luteum.
Since the dose of levonorgestrel (the main active ingredient) in the preparation is low, and all of these processes are expressed slightly. Complete suppression of ovulation does not occur, however, the contraceptive effect is achieved.
