Mechanism of Action
Combination of hormonal contraceptives inhibits ovulation by modulating pituitary secretion of gonadotrophins, luteinising hormone and follicle stimulating hormone through a negative feedback system. They reduce sperm penetration if ovulation does occur by altering the cervical mucus; cause changes in the endometrium which reduce the risk of nidation and may change the tubal transport of the ova through the fallopian tubes.
