Mechanism

It has predominant estrogen antagonistic action in uterus and breast with little action on vaginal epithelium and cervical mucus. Endometrial proliferation is suppressed by down regulation of endometrial ER. Contraceptive action is probably due to utero-embyonic asynchrony and failure of implantation. Pituitary, ovarian and other endocrine functions remain practically unaffected.
