Contraceptive Ring
The contraceptive ring is a small and flexible plastic ring which is inserted into the vagina and releases hormones into the blood.
How does it work?
The contraceptive ring works by releasing the hormones oestrogen and progesterone.
Oestrogen prevents ovulation. This is when the ovaries release an egg each month.
Progesterone thickens the mucus in the cervix so sperm cannot easily pass through and it thins the lining of the womb (endometrium) which makes it difficult for the egg to implant itself.
How long does it last?
The contraceptive ring lasts for 1 month.
Who can use it?
The contraceptive ring may not be suitable if*:
-
You have a personal or family history of breast cancer
-
Have a history of blood clots
-
Have a history of migraines
-
You smoke cigarettes
-
You are over the age of 35 years old
-

How effective is it?
The contraceptive ring is approximately 99% effective when used perfectly and 91% effective with typical use.
