Which method of contraception involves taking a daily pill that contains both oestrogen and progesterone?

The method of contraception that involves taking a daily pill containing both oestrogen and progesterone is known as the combined pill. This type of contraceptive pill works primarily by preventing ovulation, which means it stops the ovaries from releasing eggs. Additionally, it thickens the cervical mucus, making it more difficult for sperm to enter the uterus, and it also alters the lining of the uterus to prevent a fertilized egg from implanting.

The combined pill is widely used due to its effectiveness in preventing pregnancy and its additional benefits, such as regulating menstrual cycles and reducing menstrual cramps. It requires consistency in daily intake for optimal effectiveness, making it an important option for those looking for reliable contraceptive methods.

The other methods listed do not fit the description of containing both hormones as the combined pill does. The contraceptive implant and intrauterine device (IUD) are non-pill methods, while the progesterone only pill contains only one hormone. Consequently, the combined pill is the specific option that meets the requirement of containing both oestrogen and progesterone.
