Combined Contraceptive Pill - GCSE Biology Definition

Reviewed by: Lára Marie McIvor

Published

The combined contraceptive pill is a type of medication used to prevent pregnancy. It contains two hormones, oestrogen and progesterone, which are similar to the hormones naturally produced by a woman's body. These hormones work together to stop the ovaries from releasing an egg each month (ovulation), thicken the mucus in the cervix to make it harder for sperm to enter the uterus, and make the lining of the uterus thinner to prevent a fertilised egg from implanting. By taking the pill daily, it helps control these processes and provides effective protection against pregnancy. It's important for students to understand that the pill does not protect against sexually transmitted infections (STIs), and it's advised to consult with a healthcare professional for proper use and to understand any possible side effects.
