Contraceptive pill
Contraceptive pill
The Contraceptive pill, also known as the birth control pill, is a type of contraception that is taken orally. It is one of the most effective methods of preventing pregnancy.
History[edit | edit source]
The contraceptive pill was first approved for use in the United States in 1960. It was developed by Gregory Pincus, a biologist and researcher, and John Rock, a gynecologist and fertility expert.
Types of contraceptive pills[edit | edit source]
There are two main types of contraceptive pills: the combined pill and the progestogen-only pill.
Combined pill[edit | edit source]
The combined pill contains two hormones: estrogen and progestogen. These hormones prevent ovulation, thicken cervical mucus to prevent sperm from reaching the egg, and thin the lining of the uterus to prevent a fertilized egg from implanting.
Progestogen-only pill[edit | edit source]
The progestogen-only pill, also known as the mini-pill, contains only progestogen. It works by thickening the cervical mucus and thinning the lining of the uterus. Some types also prevent ovulation.
Effectiveness[edit | edit source]
When used correctly, the contraceptive pill is over 99% effective at preventing pregnancy. However, its effectiveness can be reduced if a pill is missed, taken late, or if the woman vomits or has diarrhea soon after taking a pill.
Side effects[edit | edit source]
Like all medications, the contraceptive pill can cause side effects. These can include headaches, nausea, breast tenderness, mood changes, and irregular bleeding. Most side effects are mild and improve after a few months of use.
Risks[edit | edit source]
While the contraceptive pill is generally safe for most women, it does carry some risks. These include an increased risk of blood clots, heart attack, and stroke, particularly in women who smoke and are over the age of 35.
