The pill prevents the ovaries from releasing an egg each month (ovulation). It also: thickens the mucus in the neck of the womb, so it is harder for sperm to penetrate the womb and reach an egg. thins the lining of the womb, so there is less chance of a fertilised egg implanting into the womb and being able to grow.

No, this is not true. Abortion ends a pregnancy. Birth control pills, as well as the ring, the patch, the shot, and the morning-after pill, prevent pregnancy before it happens. Birth control pills work by preventing ovulation — the release of an egg — and/or the fertilization of an egg.

The birth control pill prevents a woman's ovaries from producing an egg, creating a state called anovulation. Japanese researchers say using the pill briefly to cause anovulation may improve conditions for pregnancy to occur through in vitro fertilization (IVF) in some women.

A doctor inserts the implant under the skin of your upper arm. It releases the hormone progestin to stop you from getting pregnant. The hormones in the birth control implant prevent pregnancy in two ways: Progestin thickens the mucus on your cervix, which stops sperm from swimming through to your egg.

The birth control pill works by stopping sperm from joining with an egg (which is called fertilization). The hormones in the pill stop ovulation. No ovulation means there's no egg hanging around for sperm to fertilize, so pregnancy can't happen.

The good news is that being on birth control for a long period of time will not hurt your chances of getting pregnant in the future. Birth control pills are made of hormones that keep your eggs from ovulating and make your cervical mucus thicker, in order to keep sperm away from your eggs.

How Does It Work? Most birth control pills are "combination pills" containing a mix of the hormones estrogen and progesterone to prevent ovulation (the release of an egg during the monthly cycle). A woman cannot get pregnant if she doesn't ovulate because there is no egg to be fertilized.

Despite being small in size, birth control pills pack a punch in preventing pregnancy! This occurs through several mechanisms, mainly by stopping ovulation; when ovaries don't release eggs, sperm can't find and fertilize them to result in a pregnancy.
