It actually may contain two hormones - An Oestrogen and a Progesterone (often referred to as the combined pill).

Oestrogen prevents the release of 'Follicle Stimulation Hormone' {FSH} (which stimulates the development of primary oocytes into secondary oocytes prior to ovulation) and Progesterone will thicken secretions surrounding the cervix, making it more difficult form sperm to enter the uterus.

Oestrogen as it prevents the release of FSH, which is what stimulates the eggs ;)

if this is for your Biology 1 then i just revised this.. The contraceptive pill contains Oestrogen. Oestrogen inhibits FSH production. FSH stimulates an egg to mature so if the pill contains Oestrogen then no eggs will begin to mature stopping contraception. Hope this helps :D

Depends, the most comon is the combined pill which contains both progesterone and oestrogen. Oestrogen inhibiting the production of FSH which stops the follicle to be stimulated.  Although some women cannot take this so can take progesterone only (mini pill)  which cannot control the menstrual cycle as such (as it cannot stop the release of FSH) but does however thicken the lining of the uterus and also prevents conception. :)

The oral contraceptive pill prevents the production of FSH (Follicle Stimulating Hormone) which prevents eggs from maturing. The pills may contain Oestrogen and progesterone. Many pills now-a-day contain just progesterone or smaller amounts of Oestrogen as it leads to fewer side effects after the pills have been taken. These birth controll pills can also controll periods!
