Mechanism of action

Increase the cervical mucus viscosity. Progestogen reduces the volume of crypts, thickens cervical mucus, reduces the content of sialic acid and the activity of spermatozoa, narrows the cervical canal, thereby preventing the penetration of spermatozoa and certain microorganisms into the uterus and fallopian tubes. It is explained by both the contraceptive and therapeutic effect of progestogens in inflammatory diseases of the pelvic organs.

Reduce the contractile activity of the fallopian tubes by the threshold of the muscle cells’ excitability.

Have a specific effect on the endometrium: it causes suppression of the mitotic activity of the endometrium, the early secretion of its transformation, and with prolonged use under anovulation conditions, hypnophobia and atrophy of the endometrium, which prevents the implantation of a fertilized egg.
