Answer 3

the mechanism of combined oral pill i.e oestrogen & progesteron is to prevent the release of ovum from the ovary. this is achived by blockingthe pitutary secreation of gonadotropin that is necessary for ovulation to occur.
progesteron-only preprations render the cervical mucus thick &scanty & thereby inhibit sperm penetration

the pill is given orally for 21 days consecutively beginning on the 5th day of menstural cycle followed by break of 7 daysduring which mensturation occurs. the bleeding which occurs is not like normal mensturation, but episode of uterine bleeding from an incompletely formed endometrium caused by withdrawl of exogenous harmones/pills.
