Unit 1 - Oral Contraceptives

This GCSE Biology quiz is all about oral contraceptives - the method of birth control commonly known as 'The Pill'.

Oral contraceptives are also known as birth control pills. Human fertility is controlled by hormones so oral contraceptives contain small amounts of female sex hormones that inhibit eggs from developing in the ovary. Pregnancy is prevented because if there is no egg produced there can be no baby. Control of a woman's fertility has been a significant factor in the improvement of millions of people's quality of life worldwide.

The pill is the most popular method of birth control in the UK. Women who are not having sex also use it, as it can help to make periods less painful, lighter and more regular.
